Ancient Viral DNA Linked to Psychiatric Disorders

New research reveals how remnants of ancient infections in human DNA contribute to mental health conditions like schizophrenia, bipolar disorder, and depression.

Human Endogenous Retroviruses (HERVs) make up about 8% of the human genome.
Specific HERVs are linked to increased susceptibility to schizophrenia, bipolar disorder, and depression.
The study analyzed genetic data from tens of thousands of people and brain samples from 800 individuals.
HERV expression profiles were found to significantly impact brain function and psychiatric risk.
Further research is needed to understand the exact role of HERVs in these disorders.
