Does psychosis damage the brain?

Yes, untreated psychosis can cause significant, potentially permanent brain damage, leading to loss of brain volume (gray matter), altered brain structure, and disrupted neuronal connections, which worsens with each episode and prolonged delay in treatment (Duration of Untreated Psychosis or DUP). While research has sometimes shown inconsistent results, larger, well-designed studies suggest untreated psychosis is neurotoxic, causing atrophy, reduced gray matter in areas for memory and movement, and changes in brain networks, highlighting the critical need for early intervention.
