New research shows a possible explanation for the link between mental health and creativity. By studying receptors in the brain, researchers at Karolinska Institute have managed to show that the dopamine system in healthy, highly creative people is similar in some respects to that seen in people with schizophrenia.

High creative skills have been shown to be somewhat more common in people who have mental illness in the family. Creativity is also linked to a slightly higher risk of schizophrenia and bipolar disorder. Certain psychological traits, such as the ability to make unusual or bizarre associations are also shared by schizophrenics and healthy, highly creative people. And now the correlation between creativity and mental health has scientific backing.

"We have studied the brain and the dopamine D2 receptors, and have shown that the dopamine system of healthy, highly creative people is similar to that found in people with schizophrenia," says associate professor Fredrik Ullen from Karolinska Institutet's Department of Women's and Children's Health, co-author of the study that appears in the journal PLoS ONE.

Just which brain mechanisms are responsible for this correlation is still something of a mystery, but Dr Ullen conjectures that the function of systems in the brain that use dopamine is significant; for example, studies have shown that dopamine receptor genes are linked to ability for divergent thought. Dr Ullen's study measured the creativity of healthy individuals using divergent psychological tests, in which the task was to find many different solutions to a problem.

"The study shows that highly creative people who did well on the divergent tests had a lower density of D2 receptors in the thalamus than less creative people," says Dr Ullen. "Schizophrenics are also known to have low D2 density in this part of the brain, suggesting a cause of the link between mental illness and creativity."
The thalamus serves as a kind of relay centre, filtering information before it reaches areas of the cortex, which is responsible, amongst other things, for cognition and reasoning.

"Fewer D2 receptors in the thalamus probably means a lower degree of signal filtering, and thus a higher flow of information from the thalamus," says Dr Ullen, and explains that this could a possible mechanism behind the ability of healthy highly creative people to see numerous uncommon connections in a problem-solving situation and the bizarre associations found in the mentally ill.

"Thinking outside the box might be facilitated by having a somewhat less intact box," says Dr Ullen about his new findings.link (http://www.dosenation.com/listing.php?id=7511)

Well that explains a lot. :D

I'm pretty creative. I've let my mind go a little insane at times. Although not in a while. But when I was around 19, I would try to explore my slightly psychotic self (while alone). I didn't do drugs at that time. They were only thoughts. It was a good thing. I know myself a little better because of it. I still get a little crazy (but not in a good way) when I'm enraged.

I think this study is on to something.

Just goes to show how little we really understand about how the brain works.

People often say that "creative types" are just a little bit nuts.

People with mental issues have been drawn to writing, art, etc.

Can't say I ever linked those two things together before.

Either I'm not creative as I thought, or as schizophrenic as I thought. :p

Be careful in how you interpret and apply the results of studies like this. You have to understand that all psychological research is a mixture of qulitative and quantitative study. They must take the concept or focus of the study and "operationally define" it in order to be able to set up an experiment through which they can gain data for analysis.

In this study they chose to define creativity in this manner:

Dr Ullen's study measured the creativity of healthy individuals using divergent psychological tests, in which the task was to find many different solutions to a problem.


So, for the purpose of this study creativity was directly linked to problem solving. More specifically it was narrowed to how the test(s) used was designed to measure and define problem solving.

While this is good in that it allows for quantitative study of an abstract concept, just recognize that what they call creativity, may not fit your definition of the concept.
