The Dopaminergic Mind in Human Evolution and History

The Dopaminergic Mind in Human Evolution and History
Author: Fred H. Previc
Date: May, 2009.

What does it mean to be human? There are many theories of the evolution of human behavior which seek to explain how our brains evolved to support our unique abilities and personalities. Most of these have focused on the role of brain size or specific genetic adaptations of the brain. In contrast, Fred Previc presents a provocative theory that high levels of dopamine, the most widely studied neurotransmitter, account for all major aspects of modern human behavior. He further emphasizes the role of epigenetic rather than genetic factors in the rise of dopamine. Previc contrasts the great achievements of the dopaminergic mind with the harmful effects of rising dopamine levels in modern societies and concludes with a critical examination of whether the dopaminergic mind that has evolved in humans is still adaptive to the health of humans and to the planet in general.

Insomnia, Despair about Sleep May Raise Risk of Suicide

By Makini Brice. Counsel & Heal.
Researchers have long known that insomnia and nightmares are risk factors for suicide, but they were not sure what role that the conditions precisely played. Now, researchers believe that they may have the answer. They found that insomnia can give way to a specific form of hopelessness. While hopelessness has also long been a characteristic risk factor for suicide, this despair is different. For people who fear that they will never have a good night of sleep again, suicidal thoughts may increase.

In fact, according to WJBF, people who have insomnia that persists for over a year have up to 30 times the risk of developing depression than people who do not. An estimated 60 percent of people who have depression also have insomnia.
The study was led by Dr. W. Vaughn McCall from Georgia Regents University, and was performed in collaboration with researchers from Wake Forest University in North Carolina and the University of Louisville in Kentucky. Dr. McCall explained in a statement that he has had patients who developed increasingly negative and unfounded thoughts about their sleep, thinking that they had damaged their immune systems for good, or that one night of bad sleep would mean that their sleep for the rest of the week would be tainted as well, according to Fox News.
The study was conducted with 50 participants, with ages ranging from 20 to 80. All of the patients had depression disorder; they were all either in-patients, out-patients or being treated at the emergency department. Over half of the patients had attempted suicide before the study; most were taking some kind of antidepressant. The researchers asked all of the participants questions linked to dysfunctional sleep behavior, like "Do you think that you will ever get a good night's rest again?"
The answers surprised the researchers. "It was this dysfunctional thinking, all these negative thoughts about sleep that was the mediating factor that explained why insomnia was linked to suicide," said Dr. McCall in a statement. "If you talk with depressed people, they really feel like they have failed at so many things. It goes something like, 'My marriage is a mess, I hate my job, I can't communicate with my kids, I can't even sleep.' There is a sense of failure and hopelessness that now runs from top to bottom and this is one more thing."
The study was published in the Journal of Clinical Sleep Medicine.

Psychology of hoarding: From collecting to being buried alive

February 7, 2013. VOXXI. By Hope Gillette.


Hoarding is classified as a type of obsessive compulsive disorder; however, emerging evidence and research suggests it may be a mental condition on its own.
According to a report from Discovery Magazine, hoarding has a unique signature within the circuitry of the brain. Instead of a form of obsessive compulsive disorder, which is in turn an anxiety disorder, hoarding is thought to be a natural human instinct gone unregulated.
“Hoarding is a compulsive tendency to acquire and hold onto things, usually that one doesn’t need and doesn’t use,” F. Diane Barth, psychotherapist in private practice in NYC, told VOXXI. “It becomes pathological when the things one has hoarded take up room in one’s living space, filling up closets and covering floors, walls or furniture. Severe hoarding makes it hard for a person to carry out normal activities of daily living.”

From collecting to hoarding

According to Barth, hoarding is collecting “gone wild.” Often, hoarders don’t know what they have in their piles of things; they may buy several versions of the same item because they have no idea where the original version is, she explained.
Hoarders also often don’t use most of what they buy or collect. Unlike most collectors, they aren’t proud of what they’ve collected and have no interest in showing it to other people. In fact, hoarders are often embarrassed by or ashamed of their hoarding issues.
“Many hoarders like to think of themselves as collectors,” said Travis Osborne, a Seattle psychologist who treats hoarding and has made appearances on The Learning Channels Hoarding: Buried Alive, in a University of Washington guest lecture. “But collectors take pride in their possessions, whereas hoarders feel shame when other people see all of the stuff that they have in their homes.”

Signs of hoarding

Approximately 2.5 to 5 percent of the population in the United States is affected by a hoarding disorder, and few hoarders ever seek out treatment for their condition.
Barth tells VOXXI there are varying degrees of hoarding, and Osborne notes studies suggest more men than women hoard. The condition also seems to be more prevalent in older adults.
“…There are people who hold onto things because they have meaning — like clothing that belonged to a parent who has died — but who have not covered their entire home with their mother’s belongings; there are people whose collections, for example, books or clothes, have gotten out of control, but who are still able to live normally in their homes,” said Barth. ”And then there are people who save everything — newspapers, books, boxes and so on — whose homes are running over with stuff, so that they can barely find space to sit on a chair, sleep on their bed or cook in their kitchen, and who can’t explain why they are holding onto these things but can’t separate from them.”
Common warning signs of hoarding, according to the Mayo Clinic, include:

  • Inability or unwillingness to discard items
  • Moving items from one area to another without discarding them
  • Keeping stacks of paper
  • Keeping useless items such as napkins or trash
  • Trouble making decisions
  • Procrastination
  • Lack of organization
  • Excessive attachment to items
  • Shame or embarrassment attached to collected items
  • Limited social interaction


What items are commonly hoarded?

“Hoarding almost always starts in childhood, where they have a really hard time getting rid of things,” Osborn said in his lecture. “If there are parents or other people in the house getting rid of things, stuff doesn’t build up as much until they live on their own.”
Items commonly hoarded, according to Harvard Medical School, include:
  • Food
  • Newspapers
  • Books
  • Clothing
While television has increased the awareness of animal hoarding, experts say it is actually quite rare. Any item can be hoarded; it all depends on the individual and the emotional and mental attachment to a specific thing.

Can hoarders recover?

Cognitive behavior therapy currently shows a lot of promise in patients with hoarding issues. The method of therapy uses a trained professional to help hoarders learn to dispose of items gradually, eventually leaving them to do so on their own. Hoarders are taught to modify their thought patterns, questioning why they are keeping a particular item. Eventually, individuals are weaned off of the impulse to acquire new items.

9 Holiday Depression Busters.


By Therese J. Borchard.
PsychCentral. Dec. 2012.

It’s supposed to be the most wonderful time of the year — but not if negative emotions take hold of your holidays. So let’s be honest. The holidays are packed with stress, and therefore provoke tons of depressionand anxiety.
But there is hope. Whether I’m fretting about something as trite as stocking stuffers or as complicated as managing difficult family relationships, I apply a few rules that I’ve learned over the years.
These 9 rules help me put the joy back into the festivities — or at least keep me from hurling a mistletoe at Santa and landing myself on the “naughty” list.
1. Expect the Worst
Now that’s a cheery thought for this jolly season. What I’m trying to say is that you have to predict bad behavior before it happens so that you can catch it in your holiday mitt and toss it back, instead of having it knock you to the floor. It’s simple math, really. If every year for the last decade, Uncle Ted has given you a bottle of Merlot, knowing full well that you are a recovering alcoholic and have been sober for more years than his kids have been out of diapers, you can safely assume he will do this again. So what do you do? Catch it in your “slightly-annoyed” mitt. (And maybe reciprocate by giving him a cheese basket for his high cholesterol.)
2. Remember to “SEE”
No, I don’t mean for you to schedule an appointment with an ophthalmologist. SEE stands for Sleeping regularly, Eating well, andExercising. Without these three basics, you can forget about an enjoyable (or even tolerable) holiday. Get your seven to nine hours ofsleep and practice good sleep hygiene: go to bed at the same time every night, and wake up in the same nightgown with the same man at the same time in the same house every morning.
Eating well and exercise are codependent, at least in my body, because my biggest motivator for exercising is the reduction in guilt I feel about splurging on dessert. Large quantities of sugar or high fructose corn syrup can poison your brain. If you know your weak spot–the end of the table where Aunt Judy places her homemade hazelnut holiday balls — then swim, walk, or jog ten extra minutes to compensate for your well-deserved treat. Another acronym to remember during the holidays is HALT: don’t get too Hungry, Angry, Lonely, or Tired.
3. Beef Up Your Support
If you attend Al-Anon once a week, go twice a week during the holidays. If you attend a yoga class twice a week, try to fit in another. Schedule an extra therapy session as insurance against the potential meltdowns ahead of you. Pad yourself with extra layers of emotional resilience by discussing in advance specific concerns you have about X, Y, and Z with a counselor, minister, or friend (preferably one who doesn’t gossip).
In my life with two young kids, this means getting extra babysitters so that if I have a meltdown in Starbucks like I did two years ago — before I knew the mall was menacing to my inner peace — I will have an extra ten minutes to record in my journal what I learned from that experience.
4. Avoid Toxic People
This one’s difficult if the toxic people happen to be hosting Christmas dinner! But in general, just try your best to avoid pernicious humans in December. And if you absolutely must see such folks, then allow only enough time for digestion and gift-giving. Drink no more than one glass of wine in order to preserve your ability to think rationally. You don’t want to get confused and decide you really do love these people, only to hear them say something horribly offensive two minutes later, causing you to storm off all aggravated and hurt. (This would also be a good time to remember Rule #1.)
5. Know Thyself
In other words, identify your triggers. As a highly sensitive person (as described in Elaine Aron’s book, “The Highly Sensitive Person”), I know that my triggers exist in a petri dish of bacteria known as the Westfield Annapolis Mall. Between Halloween and New Years, I won’t go near that place because Santa is there and he scares me with his long beard, which holds in its cute white curls every virus of every local preschool. Before you make too many plans this holiday season, list your triggers: people, places, and things that tend to trigger your fears and bring out your worst traits.
6. Travel With Polyester, Not Linen
By this, I do not mean sporting the polyester skirt with the red sequined reindeer. I’m saying that you should lower your standards and make traveling as easy as possible, both literally and figuratively. Do you really want to be looking for an iron for that beautiful linen or cotton dress when you arrive at your destination? I didn’t think so — life’s too short for travel irons.
I used to be adamantly opposed to using a portable DVD player in the car to entertain the kids because I thought it would create two spoiled monsters whose imaginations had rotted courtesy of Disney. One nine-hour car trip home to Ohio for Christmas, I cried uncle after six hours of constant squabbling and screaming coming from the back seat. Now David and Katherine only fight over which movie they get to watch first. If you have a no-food rule policy for the car, I’d amend that one during the holidays as well.
7. Make Your Own Traditions
Of course, you don’t need the “polyester” rule if you ban holiday travel altogether. That’s what I did this year. As the daughter/sister who abandoned her family in Ohio by moving out east, it has always been my responsibility to travel during the holidays. But my kids are now four and six. I can’t continue to haul the family to the Midwest every year. We are our own family. So I said this to my mom a few weeks ago: “It’s very important that I spend time with you, but I’d like to do it as a less stressful time, like the summer, when traveling is easier.” She wasn’t thrilled, but she understood.
Making your own tradition might mean Christmas Eve is reserved for your family and the extended family is invited over for brunch on Christmas Day. Or vice versa. Basically, it’s laying down some rules so that you have better control over the situation. As a people-pleaser who hates to cook, I make a better guest than host, but sometimes serenity comes in taking the driver’s seat, and telling the passengers to fasten their seatbelts and be quiet.
8. Get Out of Yourself
According to Gandhi, the best way to find yourself is to lose yourself in service to others. But that doesn’t necessarily mean holding a soup ladle. Since my name and the word “kitchen” have filed a restraining order on each other, I like to think there are a variety of ways you can serve others.
Matthew 6:21 says “for where your treasure is, there your heart will be also.” In other words, start with the things you like to do. For me, that is saying a rosary for a depressed Beyond Blue reader, or visiting a priest-friend who needs encouragement and support in order to continue his ministry, or helping talented writer friends get published. I’d like to think this is service, too, because if those people are empowered by my actions, then I’ve contributed to a better world just as much as if I had dished out mashed potatoes to a homeless person at a shelter.
9. Exercise Your Funny Bone
“Time spent laughing is time spent with the gods,” says a Japanese proverb. So, if you’re with someone who thinks he’s God, the natural response would be to laugh! But seriously folks, research shows that laughing is good for your health. And, unlike exercise, it’s always enjoyable! The funniest people in my life are those who have been to hell and back, bought the t-shirt, and then accidentally shrunk it in the wash. Humor kept them alive — physically, emotionally, and spiritually. Remember, with a funny bone in place — even if it’s in a cast — everything is tolerable.

Listen to the sounds of the human mind: Remixed brain scans reveal our inner music


  • Researchers suggest it could potentially lead to to advances useful for clinical diagnosis or biofeedback therapy



Scientists have combined and translated two kinds of brain waves into music, offering a unique insight into the functional activity of our minds. Researchers used electroencephalography scans to create the pitch and duration of notes and functional magnetic resonance imaging scans to control the intensity of the music.

The study, published in the open access journal PLoS ONE, reveals an improved method to reflect the physiological processes of the scale-free brain in music. Previous research published in PLoS ONE by the same group has described how EEG amplitudes and waveforms may be converted to music. In the past, researchers at the U.S. Department of Homeland Security's Science and Technology Directorate have also explored the possibility of a form of neuro-training called 'Brain Music'.

This uses music created from an individual's brain waves to help the individual move from an anxious state to a relaxed state. But this new study by Jing Lu and colleagues from the University of Electronic Science and Technology, China, uses simultaneous EEG and fMRI recordings to better represent the activity of the brain in musical notes.

According to the researchers, this brain music 'embodies the workings of the brain as art, providing a platform for scientists and artists to work together to better understand the links between music and the human brain.' The authors also suggest that combining EEG and fMRI data may produce music that better reflects the functional activity of the brain, potentially leading to advances useful for clinical diagnosis or biofeedback therapy.

A psychologist with schizophrenia talks about what helps him function effectively


Taken from the book: “Abnormal Psychology” by David Homes.  Harpers Collins. ©1991.

Frederick J. Frese III is a psychologist who has struggled with schizophrenia for over 20 years. He described the onset of his symptoms and talked about his occasional “breakdowns”. Most of the time, however, he functions effectively, and in the following comments he describes some of the things that help. Dr. Frese believes it is important that the person whit schizophrenia be aware of the nature of the problem in order to develop effective coping strategies. He said:

Person whit schizophrenia needs to carefully study how they function. Until they can identify their deficits, it is very difficult to start building compensatory mechanisms that will enable them to function better… persons recovering from schizophrenia should be able to identify, and be on the lookout for, the sorts of persons, places, and things that can cause the type of stress that may precipitate their breakdowns. They should know to get to environments that are helpful.

Just as a diabetic must take action to control his or her blood-sugar level, persons recovering from schizophrenia must learn to monitor and take measures to counteract an imbalance in subcortical neurochemical activity. But unlike diabetes, schizophrenia seriously interferes with rational processes, and once the irrationality begins, the person may have great difficulty in acting in a rational or responsible manner.

To overcome the irrationality, Dr. Frese also emphasizes the importance of feedback from others:

Because of our disability, it is very difficult for us to know what we do that normal do not understand. Therefore, it is very helpful to have a trustworthy normal around to let us know what it is about our thoughts that perhaps it would be better not to share with everyone else. In my case, my wife constantly gives me feedback whenever I am saying or doing things that normal people may consider bizarre or offensive. Some things are rather obvious. If you are hearing voices, it is generally best not to talk back to them while normal are around. If your thoughts are dominated by the importance of the colors or similar sounds in the environment, you probably do not want to reveal too much about this to others.

Whit help, other disabled persons learn to compensate for their disabilities and frequently lead dignified, productive lives. The blind learn to use canes and seeing-eye dogs; those with limited use of their legs learn to use crutches and wheelchairs. For the mentally ill, however, the parameters of our disability are often not easily defined. We need help and feedback so we can understand exactly the nature of our disability.

Whit regard to the results of psychological testing, Dr. Frese said:

Assessment results that us we have “gross pathology”, “extreme confusion” or “diffuse brain damage” are not really helpful. We need very specific information. Perhaps new assessment instruments need to be developed, possibly with input from us, so that we can better learn how it is that we are different from others or where our psychological blind spots are.

Unfortunately, feedback is not always enough. Sometimes the symptoms overwhelm the person, who then loses the ability to function. When that occurs, some flexibility on the part of other people in the environment is necessary. Dr. Frese commented:

Schizophrenia tends to be an episodic disorder. We are going to have periodic breakdowns. This makes holding employment very difficult because the usual practice is to terminate employees who require frequent periods of leave. Work for us should be structured so that our disabilities are taken into account. Many of us are well educated and/or have useful skills when we are not having episodes. Why can´t jobs be structured for us so that our episodic breakdowns do not automatically result in our loss of employments? As with those in the general population, we like and needs to be a little more flexible in understanding that we are going to behave strangely from time and there are going to be time when we do not function well at all.

A Psychological Analysis of Chuck Palahniuk's Fight Club


How the World of Psychology Applies to This Famous Novel.

by Bryan R. Price.
Yahoo! Contributor Network.
May, 2007.

Fight Club was originally a novel by Chuck Palahniuk, and was made into a movie a short time after the book's success. Palahniuk's contemporary and often vulgar writing style has made the author not only a good fortune, but a huge fan base of support. In all of Palahniuk's books, a great deal of psychology theory and ideas are present- and Fight Club is no different.

Fight Club's success is more than just well written content- it was a book and movie geared towards younger men. Books such as "Little Women" and other women-themed movies were plentiful- but the same could not be said for male content. The book and movie differ in many ways- so focus will be put on the movie. In the movie, the main character's name is somewhat of a mystery. Through various clues, the avid film buff will notice that small hints suggest the character's name is Jack Moore, as seen on a check.
Jack is a rather disturbed individual, who suffers from insomnia. Jack sees a doctor, who tells him to visit a support group to see what pain really was- and declined to give Jack medicine. Jack finds an ability to sleep after going to these support groups, often of which he ends up crying to relieve stress from a common office job, common apartment, and a dull, bland, life. This is where things take a turn for the worst- as Marla Singer is introduced. She makes an appearance at one of the support groups for males only- so she is clearly what Jack calls a "faker". Jack is also a "faker", of course, but he finds that he can not enjoy the support groups knowing that Marla is there faking along with him. Eventually, he confronts her and they work out a temporary solution- which ultimately ends up failing.
Meanwhile, Jack meets Tyler Durden. Tyler is a strong hater of common culture, and considered to be a nihilist. Tyler and Jack form a much more involved friendship after Jack's apartment explodes- which effectively ruins his life and everything he owned. Tyler and Jack end up fighting in a parking lot out of being curious, and end up forming a fight club when other men start to join. These applicants are usually the type that grew up without a father- a rather interesting fact to take note while watching.
Throughout the movie, Tyler and Jack start to drift apart, as Tyler forms a project to attack popular consumer culture. Eventually, Jack and Tyler find themselves at the end of their efforts, with Tyler ready to watch a few credit card buildings explode from the amount of explosives he had ordered to be planted. Jack realizes that Tyler is actually him- and nothing more than an apparition or split personality. Jack ends up putting a gun inside his mouth and pulling the trigger, only to still live and realize that Tyler is gone. Jack then wakes up in a mental hospital, with the movie ending with a scene of the fight club members planning to continue their efforts against society- and claiming Tyler will come back.
The movie and book both focus on existentialism- which is the philosophy that an individual must make meaning from a chaotic and empty universe- and this individual is often the object of suffering. Throughout the movie, there are scenes where there is clear cut evidence of this. For instance, Tyler claims, "Only after disaster can we be resurrected" [1]. Another piece of evidence of existentialism comes when Tyler states, "It's only after we've lost everything that we are free to do anything." At one point, Tyler inflicts a chemical burn onto Jack, which is a lesson that tries to explain the sole fact that you will never get anywhere in life until hitting rock bottom. Existentialism defines the need for one to make decisions to better one's life- and that a person is who they are determined to be. Clearly, the movie focuses on this philosophy throughout the entire movie- as several main themes and subtexts are based from it.
Sigmund Freud is a notable psychologist that suggested the existence of the id, ego, and superego. The id is essentially the driving force that demands pleasure constantly [2]. The ego is the checks and balances of the id, as it waits for a safe or healthy moment for pleasure to be obtained. Finally, the superego is the moral standard that suppresses the id. Jack has a very interesting system of morals in Freud's terms. Jack is first satisfied with the common, bland life of having a normal job and condo. His superego is clearly doing a great job. However, it may be functioning all to well- as the id apparently creates Tyler Durden in an attempt to overcome its suppressor. While the id is successful in achieving its purpose, the ego is still operational. While it is hard to see, as Tyler and Jack are exact opposites- the ego acts as a mediator between the two in the end of the conflict. As Jack and Tyler become equally aware of each other, the ego can claim responsibility of bringing a sense of peace to the situation.
Also, there is the matter of gender identity confusion to take into effect. Although Jack shouldn't be considered feminine, there is a definite difference between Jack and Tyler in regards to masculinity. For instance, Jack collects furniture for a hobby. This is far from masculine, and far from the gender identity of Tyler. It would seem that the gender identity confusion adds to the correct balance of id and superego [3] - and ultimately helps Jack achieve things he otherwise could not. For instance, Jack gets into his first fight, albeit with himself. He defies his boss, in an act of rebellion against conformity. He also finds an attractive woman to date off and on, depending on the state of his identity. This lack of masculinity could be attributed to Jack's lack of a father figure in early childhood- but either way, it ends up causing catastrophic consequences in his personality.
Another psychologist, Abraham Maslow, suggested the idea of self-actualization. This is the idea that all humans try to make the most of their abilities, and to strive towards success to the fullest ability [4]. Individuals who achieve such self-actualization are considered to be creative, embrace facts rather than avoid them, spontaneous, appreciate life, like to solve puzzles, and of course have morals. Essentially, this is the act of achieving the peak of one's potential. Interestingly, there is a paradox within Fight Club concerning this subject. Tyler claims that men who wish to achieve freedom from a controlling father-figure will only be self-actualized once they have children and become fathers themselves. Essentially, the only way to self-actualization in this statement is to become what you are trying to defy. However, the narrator eliminates Tyler through shooting himself- and achieves self-actualization in effect.
Obviously, following a matriarch-style of development has either directly given Jack his problems, or at least contributed to them. As with other characters in the book and movie, most notably in the fight club, the majority of men relate to Jack through not experiencing a father figure. This has led a generation of youth develop without the guidance of a father- and in essence shaped masculinity through much harsher means. Interestingly, this has made an increase in schizophrenics [5]. Poverty is usually a cause of schizophrenia, and this is very much more common among single mother families than that of couples or single father families. This makes it very possible that Jack was suffering from schizophrenia because of poverty- although other factors could have been a direct cause. Heredity is another big cause of the disorder- and Jack's father was not mentioned in this context. It would appear that the exact cause of Jack's possible schizophrenia can not be determined because of lack of evidence.
Finally, it is important to relate psychosis and sleep deprivation to the film. Jack suffers from a bad case of insomnia- which can have detrimental effects. These effects can lead to forms of psychosis [6] - which makes schizophrenia a very viable effect as a result. When Jack is denied medication, he instead finds release in another form. Because of this he experiences schizophrenia less than he was before, although he might not have known it. It would seem that everything follows a massive chain reaction- which eventually leads to schizophrenia and an eventual internal conflict.
Fight Club is incredibly accurate in terms of validity. This comes to no surprise, as the author is both very qualified and very knowledgeable. Everything that could be explained in medical terms can likewise be explained through several theories or ideas. The effects of these health afflictions are very real- such as the insomnia or schizophrenia. Interesting psychological terms such as self-actualization and gender identity come into play- and with amazing accuracy. It seems Hollywood has made a successful and fact-proven work of art. Although, it would seem the credit should likely go to Chuck Palahniuk- who sold the rights of his works to have a movie made. Overall, the movie is incredibly accurate, and is definitely worth a place in any movie collector's shelf.

Brain Abnormalities in Schizophrenia Due to Disease, Not Genetics

Brain Abnormalities in Schizophrenia Due to Disease, Not Genetics
By  Associate News Editor
Reviewed by John M. Grohol, Psy.D. on August 3, 2012


The brain differences found in people with schizophrenia are mainly the result of the disease itself or its treatment, as opposed to being caused by genetic factors, according to a Dutch study.

Schizophrenia is a mental disorder that significantly affects cognition and usually contributes to chronic problems with behavior and emotion. Along with a breakdown of thought processes, the disorder is also characterized by poor emotional responsiveness, paranoia, auditory hallucinations and delusions.

People with schizophrenia are likely to have additional conditions, including major depression and anxiety.

The strong familial link of schizophrenia is thought to be as high as 81 percent, and researchers have suggested that schizophrenia-related brain abnormalities may be present in unaffected relatives, a notion that has been supported by several studies.

For the current study, Heleen Boos and a team from University Medical Center Utrecht performed structural magnetic resonance imaging (MRI) whole-brain scans on 155 patients with schizophrenia, 186 of their non-psychotic siblings, and 122 healthy controls (including 25 sibling pairs).

Researchers used the images to measure volume, cortical thickness and to map the brain anatomy in order to evaluate group differences.

Compared with healthy controls, participants with schizophrenia had strong reductions in total brain, gray matter, and white matter volumes, and significant increases in lateral and third ventricle volumes after taking into account age, gender, intracranial volume, and left or right handedness.

However, there were no significant differences in brain volume between unaffected siblings and healthy controls.

Schizophrenia patients also showed cortical thinning compared with healthy controls, and had decreased gray matter density. Again, this was not found in unaffected siblings and healthy controls.

“Our study did not find structural brain abnormalities in nonpsychotic siblings of patients with schizophrenia compared with healthy control subjects, using multiple imaging methods,” the team says.

“This suggests that the structural brain abnormalities found in patients are most likely related to the illness itself.”

"Si oyes voces y ves visiones..., ¡no estás mal de la cabeza!" - John Read


John Read, psicólogo especialista en abusos sexuales y psicosis.

26/05/2012 por Víctor M. Amela. La Vanguardia.

¿Locura... o sentido?
John Read superó el trauma psicológico de una familia disfuncional y un abuso sexual en la infancia. Sus vivencias y su curiosidad le llevaron a investigar la psique humana y a estudiar eso que llamamos locura. Read ha concluido que lo mejor es tratar amorosamente a pacientes a los que hemos etiquetado como psicóticos y esquizofrénicos. Y lo argumenta en libros como Modelos de locura o El sentido de la locura (Herder). Read me pondera el trabajo en España del doctor Jorge Tizón y su equipo de atención precoz a pacientes en riesgo de psicosis (con el patronazgo de la Fundació Llegat Roca i Pi) y me anima a visitar InterVoiceOnline.org. Este Read me ha parecido muy cuerdo.

¿Qué es la locura?
El término para definir comportamientos inusuales en el seno de una cultura.

¿La locura... es cultural?
¡Claro! Conozco a fondo la cultura maorí, y sé que en esa cultura no es síntoma de locura oír voces.

¿No?
Aprenden desde niños que eso encaja en la normalidad..., ¡y nadie se asusta! Nadie cree que uno esté loco sólo por oír voces...

Aquí sí, aquí te llevan al médico...
Allí entienden que es un ancestro que acude a ayudarte. Lo agradeces..., ¡y a otra cosa!

Pues si yo oigo voces, ¡sí me espantaré!
Porque te han enseñado que eso es estar mal de la cabeza, enfermo, y te internarán, tratarán...: vives con ese relato miedoso.

Oír voces, entonces, ¿no es patológico?
Para la especie humana, no es nada raro oír voces y ver visiones: ¡es parte de nuestra naturaleza! El 15% de la gente oye voces.

No sabía esto, explíquemelo...
Mire, el 80% de las personas mayores de 60 años que ha perdido a su pareja o a algún ser muy querido... ¡lo oirá o lo verá en algún momento durante el primer año de duelo!

¡¿Tantas personas?!
Pero preferimos no comentarlo con nadie...

¿Le ha pasado a usted?
Un buen amigo mío se mató en accidente de coche... Lo lamenté tanto... Al día siguiente se me apareció, vino a despedirse de mí...

¿Hay explicación científica?
Lo primero es aceptar el hecho sin problematizarlo, pues lo que ayuda no es saber cómo sucede, ¡sino dilucidar qué significa!

¿Y qué significa?
¡Es un mensaje a encajar en la biografía de quien lo vive! Pero el psiquiatra, en vez de escuchar al paciente..., ¡lo dopa! Debería ver cómo encaja el mensaje en su relato vital.

¿Lo llamamos locura... y es un mensaje?
Sí. El psiquiatra debe lograr, con humildad, sensibilidad y paciencia, que el paciente se convierta en autor del relato de su vida...

¿Y no lo hacen así los psiquiatras?
En España, los profesores universitarios de psiquiatría ¡cobran de la industria farmacéutica! En estas condiciones..., me daría vergüenza ser psiquiatra en España.

¿En el resto del mundo no es así?
También en Estados Unidos... Y me abochorna que dilapidemos fortunas buscando el gen de la locura, de la esquizofrenia: ¡no existe! No hay raíz biológica de la locura.

¿Dónde debemos buscar, pues?
En el propio relato del paciente, insisto. Darle drogas antipsicóticas... ¡sí es una locura!

¿Tan contraproducentes son?
Perjudican más que benefician, por lo que deberían prohibirse. ¡Acortan diez años la vida del paciente así medicado!

¿En qué casos sí benefician?
Sólo para tranquilizar al paciente durante una crisis: eso es sólo un tercio de los casos.

¿Aconsejaría a los pacientes abandonar ahora mismo los antipsicóticos?
¡Que nadie deje a solas la medicación! Es arriesgado. Dialogad con el psiquiatra y pedidle ayuda para contactar con grupos de terapias mentales sin fármacos, que los hay.

¿Cómo trata usted a sus pacientes?
Un caso: uno llevaba treinta años medicándose porque se sentía observado y espiado y quería convertirse en mujer. Me bastaron seis meses conversando con él para entrar en su lógica y ayudarle a mejorar.

¿Conclusión?
La buena calidad de la relación terapeuta-paciente es lo más curativo que hay. ¡No existe mejor medicina!

¿Algún consejo para el terapeuta?
Escucha al paciente con paciencia, sin hacerle sentir enfermo mental y sin juzgarle.

¿Alguna otra evidencia científica sobre lo que llamamos locura y su tratamiento?
En países africanos, es la propia locura la que cura: los chamanes provocan brotes psicóticos con drogas, con fines curativos...

¿Con qué resultados?
El dato científico es que dos tercios de los psicóticos se recuperan en África. Aquí sólo recuperamos a un tercio. ¡Aprendamos!

¿Qué le llevó a aprender psicología?
La necesidad de entenderme a mí mismo.

¿Qué le pasaba?
De los 11 a los 13 años fui víctima de abusos sexuales por parte del director de mi colegio. No entendía qué estaba pasando y me vengué del mundo suspendiéndolo todo...

¿Qué efectos tiene un abuso?
Si no se repara, es un trauma psíquico que puede derivar en psicosis y esquizofrenia.

¿Es muy frecuente el abuso sexual?
En Occidente, el 20% de las niñas y el 15% de los niños padecen abusos sexuales...

¿Con efectos iguales en niños y niñas?
La niña se aislará de otros niños. El niño abusará psicológicamente de otros niños.

¿Cómo debemos actuar ante un abuso?
Hay que alejar al abusador. Y preguntar al niño y escucharle. Y hacerle entender que él no ha actuado mal. Y ayudar a los progenitores inocentes. ¡Y dar mucho cariño y amor al niño! Si se hace así, se repondrá.

¿Puede pasarle algo peor a un niño?
También es muy traumático chillarle y reñirle y abroncarle continuamente..., y tanto peor cuanto más joven, porque se dañan más los reguladores neuronales del estrés.

¿Con qué consecuencias?
Tú dile al niño continuamente que es muy malo o un desastre... y será fiel a este relato, porque los niños creen íntimamente a sus padres. Y será malo y será un desastre. Y psicótico, depresivo... y eventual suicida.

Scientists Find Truth in "Mad Scientist" Stereotype: There Is a Link between Genius and Insanity



By Christine Hsu. Medical Daylt. June 04, 2012.
Genius and insanity may actually go together, according to scientists who found that mental illnesses like schizophrenia and bipolar disorder are often found in highly creative and intelligent people.
The link is being investigated by a group of scientists who had all suffered some form of mental disorder. 
Bipolar sufferer Kay Redfield Jamison, a clinical psychologist and professor at Johns Hopkins University School of Medicine, said that findings of some 20 or 30 scientific studies confirms the idea of the "tortured genius" or "mad scientist".   
Jamison said that creativity appears to be significantly linked to mood disorders, especially bipolar disorder.  For instance, one 2010 study that tested the intelligence of 700,000 Swedish 16-year-olds found that highly intelligent adolescents were more likely to develop bipolar disorder in a decade-long follow-up.
"They found that people who excelled when they were 16 years old were four times as likely to go on to develop bipolar disorder," Jamison said Thursday night during a panel discussion at New York’s World Science Festival.
Bipolar disorder is a condition in which people have dramatic mood swings between "mania" or extreme happiness and severe depression. 
Panelist and researcher James Fallon, a neurobiologist at the University of California-Irvine said that research found that people who suffer bipolar disorder tend to be more creative when they’re coming out of deep depression. 
Fallon suggested that when a bipolar patients' mood improves, activity decreases in the lower part of a brain region called the frontal lobe and increases in a higher part of that lobe, a shift that is also seen when people have bouts of creativity.
"There [is] this nexus between these circuits that have to do with bipolar and creativity," Fallon said at the panel.
Elyn Saks, a mental health law professor at the University of Southern California who also developed schizophrenia as a young adult, said that people with psychosis do not filter stimuli as well as others without the disorder, meaning that they're able to ponder contradictory ideas simultaneously and gain insight into loose associations that the general unconscious brain wouldn't even consider worthy of sending to consciousness.
Saks said that while the invasion of nonsense into conscious thought can be overwhelming and disruptive, "it can be quite creative, too."
Studies on word associations that ask participants to list all the words that come to mind in relation to a stimulus word like "tulip" found that bipolar patients experiencing mild mania can generate three times as many word associations in the same amount of time as the general population. 
The findings suggest that mania can lead to bouts of genius because the great amount of unsuppressed ideas means a greater probability of producing something original and profound.
Many prodigies like painter Van Gogh, author Jack Kerouac and mathematician John Nash had displayed self-destructive behaviors, and it is unclear as to why humans have evolved this trait. 
"The notion of a 'tortured genius' or 'mad scientist' may be more than a romantic aberration," says the World Science Fair. "Research shows that bipolar disorder and schizophrenia correlate with high creativity and intelligence, raising tantalizing questions: What role does environment play in the path to mental illness?"
Scientists wonder whether the mental disorders are being positively selected for in the gene pool, and if there is actually a line between gift and deficit. 
Past studies have suggested that much of the link between genius and madness is produced by one particular gene called the DARPP-32, and that three out of four people inherit a version of the DARPP-32 gene, which enhances the brain's ability to think by improving information processing in the prefrontal cortex of the brain. 
However panelists noted that while society benefits from the productivity of its "tortured geniuses," people who are affected by mental disorders that often lead to bouts of creative energy don’t always consider their moment of brilliance to be worth their suffering.
"I think the creativity is just one part of something that is mostly bad," Saks said.

Ritalin use for ADHD children soars fourfold

Pupils as young as three are at risk from untested drug cocktails, warn experts as prescriptions soar.

More youngsters are being prescribed Ritalin for ADHD despite clinical guidelines to the contrary, say child psychologists.
Jamie Doward and Emma Craig. The Observer, May 2012. The Guardian U.K.
Prescriptions of Ritalin for attention deficit hyperactivity disorder have quadrupled in a decade, prompting fears it is being pushed on childrenat the expense of alternative treatments and without appreciation of long-term effects.
Figures released by the NHS business services authority to the Liberal Democrat MP Tessa Munt reveal the number of prescriptions of methylphenidate hydrochloride, the generic name for Ritalin, rose in England from 158,000 in 1999 to 661,463 in 2010.
Ritalin is a psychostimulant drug most commonly approved for treatment of ADHD in children. It is also used to treat conditions such as narcolepsy and in certain cases may also be prescribed for lethargy, depression and obesity.
The Association of Educational Psychologists said its members were reporting an increase in children with behavioural difficulties being prescribed the drug in conjunction with antidepressants, despite the fact there was "little to no evidence about the effect which these cocktails ofdrugs are having on the development of children's brains".
The association claims clinical studies show the "beneficial effects of psychostimulant medication are not sustained over the long term, necessitating stronger and stronger dosages to be prescribed over time" and that it is "becoming a common practice for children to be prescribed stronger dosages than recommended in the morning as a 'top-up' or 'kickstart' dose so that medication lasts the full school day".
Munt, who until recently sat on the education select committee, said there were natural alternatives that could help combat ADHD. She highlighted a report commissioned by the RSPB that suggested activities in a natural environment appear to improve children's symptoms by 30% compared with urban outdoor activities, and threefold compared to playing indoors. But Munt said many young people were prevented from enjoying the outdoors because of reasons such as lack of school playing fields and the distractions posed by video games, smartphones and social networking.
"It is extremely alarming that in the decade up to 2010, prescriptions for Ritalin quadrupled," she said. "Statistics show that 90% of prescriptions for this powerful drug in 2004 were used to combat behavioural problems in school-age children. I am shocked that there has been such a huge explosion in use."
ADHD is believed to affect between 5% and 10% of schoolchildren in the UK. Symptoms include overactive and impulsive behaviour and difficulty paying attention. The increase in Ritalin prescriptions appears to mirror the US where there was an 83% increase in sales of the drug between 2006 and 2010.
How many children are being prescribed the drug is difficult to quantify from official data. Munt said: "Unless the Department of Health collects vital statistical data about prescribing habits, no one will know what is happening.
"We hear teachers tell of their students' lack of ability to concentrate, from police about increasingly disruptive and antisocial behaviour, and from parents unable to control the actions of young family members. We need to show young people how to deal with the normal stresses and strains of growing up. Resorting to powerful drugs only stores up trouble for the future."
The Association of Educational Psychologists said it believed guidelines were not being followed. The guidelines recommend that ADHD medication should not be prescribed to pre-school children for the long term.nor in isolation from other therapeutic interventions, without consultation But the association said it was aware of a substantial increase in the number of children aged under six, and in some cases as young as three, being prescribed ADHD drugs. It said an informal survey of educational psychology practitioners across the West Midlands had revealed there were more than 100 children under six on the medication in the area. "This is reaffirmed across the country by our members," the association said.
