Schizophrenia, bipolar disorder and artistic creativity may share some genetic roots, a study published in the journal Nature Neuroscience, on Monday said.
The research delves into a distinguished genetic database called the deCODE library of DNA codes sprung by the Iceland population sample.
Genetic and medical data of 86,000 Icelanders were compared by establishing DNA signature pointing to a doubled risk of schizophrenia and a third of an increase in bipolar disorder.
The genomes of artistic people were scrutinized. More than 1,000 volunteers were members of the Icelandic national societies for writing and music, visual arts, dance and theatre.
The study found that the artistic members of these organizations have a 17% likelier chance, compared to non-members, to have the same genetic signature.
4 studies from the Netherlands and Sweden supported the study, which is composed of about 35,000 people that compared individuals from the general public and from artistic occupations.
Although different parameters were used by the investigations, it resulted to a 23% higher probability.
Kari Stefansson, who led the study and headed the deCODE Genetics said, “We are here using the tools of modern genetics to take a systematic look at a fundamental aspect of how the brain works.”
“The results of this study should not have come as a surprise because to be creative, you have to think differently from the crowd, and we had previously shown that carriers of genetic factors that predispose to schizophrenia do so,” he disclosed during a news release.
