A mysterious brain network may underlie many psychiatric disorders

Scientists have uncovered a mysterious network of brain connections that is linked to several psychiatric disorders, including schizophrenia, depression and obsessive-compulsive disorder (OCD).

This shared brain circuitry could help reveal why many patients who are diagnosed with one psychiatric illness also meet the criteria for a second.

"Half of the people we treat meet criteria for more than one disorder," Dr. Joseph Taylor(opens in new tab), clinical director of transcranial magnetic stimulation at the Brigham and Women's Hospital's Center for Brain Circuit Therapeutics in Boston and first author of a study describing the discovery, told Live Science. The study, published Thursday (Jan. 12) in the journal Nature Human Behaviour(opens in new tab), supports the idea that disorders that often occur together may stem from the same neurobiological roots.
