Schizotypal personality disorder — structured clinical viva

This presentation is most consistent with schizotypal personality disorder if a longitudinal pattern meets DSM ≥5 of 9 features with general PD criteria: cognitive-perceptual oddness (ideas of reference with residual doubt), interpersonal deficits, and eccentricity, without frank sustained psychosis. Working part-time and questioning referential ideas argue against current schizophrenia, but you must still take a full history for duration, functional trajectory, substances, depression, ASD developmental profile, and family history.[1][2]

Risk. Separate (a) suicide/self-neglect risk linked to depression and isolation from (b) conversion risk if conviction and function worsen, and (c) parenting capacity/safeguarding, which depends on functional impairment, insight, and specific behaviours — oddness alone is not automatic child removal. Assess capacity decision-specifically and act on statutory safeguarding duties when indicated without inventing foreign legal sections.[1][5]

Treatment answer to the GP. Psychotherapy/alliance-first psychosocial care is foundational. No antipsychotic is a disease-modifying “personality drug.” Time-limited low-dose antipsychotic trials may be considered for severe cognitive-perceptual distress with targets and review dates; evidence certainty is limited (Jakobsen; Kirchner; Gundersen GRADE). Treat depression/anxiety properly. Monitor conversion and escalate to early psychosis pathways if frank psychosis or UHR thresholds with decline emerge.[2][3][4][5]
