What is Early-Onset Psychosis (First Episode)?

First-episode psychosis (FEP) refers to the first time a person experiences psychotic symptoms — delusions, hallucinations, disorganized thinking, or grossly disorganized behavior — typically emerging in late adolescence and early adulthood. Early intervention services have demonstrated substantial benefits in functional outcomes, relapse prevention, and reduction of duration of untreated psychosis (DUP), the strongest modifiable predictor of long-term outcome.

Differential diagnosis includes schizophrenia spectrum disorders, brief psychotic disorder, schizoaffective disorder, major depression with psychotic features, bipolar disorder with psychosis, substance/medication-induced psychosis (cannabis, methamphetamine, hallucinogens), psychosis due to medical conditions (autoimmune encephalitis, temporal lobe epilepsy, neurosyphilis, HIV, Wilson disease, lupus cerebritis, NMDA receptor encephalitis), and prodromal/at-risk mental state.

Comprehensive evaluation includes psychiatric interview, mental status examination, collateral history from family, baseline labs (CBC, metabolic panel, TSH, vitamin B12, syphilis, HIV), urine toxicology, and brain imaging (MRI preferred). Treatment is built on three pillars: low-dose antipsychotic medication (aripiprazole, risperidone, lurasidone, paliperidone preferred for tolerability), psychosocial intervention with cognitive-behavioral therapy for psychosis (CBTp), family psychoeducation, and supported employment/education. Early intervention teams (assertive outreach) reduce relapse and improve recovery.
