Why Symptoms of Schizophrenia Emerge in Young Adulthood

ScienceDaily (Feb. 25, 2010) — In reports of two new studies, researchers led by Johns Hopkins say they have identified the mechanisms rooted in two anatomical brain abnormalities that may explain the onset of schizophrenia and the reason symptoms don't develop until young adulthood. Both types of anatomical glitches are influenced by a gene known as DISC1, whose mutant form was first identified in a Scottish family with a strong history of schizophrenia and related mental disorders. The findings could lead to new ways to treat, prevent or modify the disorder or its symptoms.

Taken together, Sawa says, results of both studies suggest that these anatomical differences, which seem to be influenced by the DISC1 gene, cause problems that start before birth but surface only in young adulthood.
