Story summary

A study reveals that many psychiatric disorders share genetic similarities, suggesting they may not need to be treated as distinct conditions.
Researchers analyzed DNA from 1 million individuals with psychiatric disorders and identified a pervasive genetic overlap across conditions.
They defined five genetic-based categories, including compulsive features and internalizing conditions, and noted that about 70% of schizophrenia signals are linked to bipolar disorder, with the European-ancestry focus potentially limiting applicability.
