A study of brain scans shows that gene mutations affect the structure and function of the brain. This mutation affects the gene, DISC1, which has been linked to schizophrenia and bipolar disorder.
This gene was found by studying a family prone to mental illnesses. They've been studying this for over 40 years.
This discovery could lead to new treatments for mental illnesses.
Professor Stephen Lawrie, Head of the Division of Psychiatry at the University of Edinburgh, said:
“This study confirms and extends the genetics of DISC1, and shows how that and similar genetic effects can increase the risk of major mental illnesses.”
The study was published in the journal, Nature.
