13 snips
Apr 3, 2026 Franciska de Beer, researcher and PhD candidate focused on first-episode psychosis, discusses psychiatrist-driven outcome differences and why clinicians explain about 10% of symptom and functioning variance. She covers antipsychotic tapering versus maintenance, dopamine supersensitivity after strong D2 blockers, tapering strategies to avoid rebound, and sex- and menopause-related drug level differences.

Episode notes
Baseline Recovery Predicts One Year Outcome
- Baseline severity strongly predicts one-year outcome, explaining ~38.6% of variance, overshadowing psychiatrist effect magnitude.
- Early recovery status (how well someone recovers initially) is a major prognostic indicator for first-episode psychosis.
Team Composition Influences Recovery
- Team factors beyond the psychiatrist matter: frequency of psychologist contact related to psychosis severity and different patients need different combinations of care.
- Future research should examine team composition and which patients benefit from which resources.
Two Trajectories After Stopping Antipsychotics
- In HAMLETT follow-up, two distinct clusters emerged after stopping antipsychotics: one relapsed quickly and was more often male with higher care needs.
- Another cluster stayed well long-term; they were higher functioning, younger, often with partners and prior drug use that later decreased.
