Obsessive-compulsive symptoms (OCS) are often associated with schizophrenia. So far no single pathogenetic theory was able to convincingly explain this co-occurrence, due to heterogeneous subgroups within the comorbid sample. Based on long-term case observations, one hypothesis assumes that second-onset OCS in the course of schizophrenia might be a side effect of second generation antipsychotics (SGA), most importantly clozapine (CLZ). This review summarizes the supporting epidemiological and pharmacological evidence and defines several open questions regarding pathogenetic influence of genetic factors, differential neurocognitive profiles, affective comorbidity and interactions of serotonergic, dopaminergic and glutamatergic neurotransmission. Treatment of comorbid patients might involve cognitive behavioural therapy (CBT) with graduated exposure and response prevention (ERP). However, so far no controlled clinical trials confirmed efficacy and tolerability of psychotherapy for this specific indication. Strategies of polypharmacy are often preferred, although based on similarly scarce systematic evidence. The combination of amisulpride or aripipirazole with pro-obsessive, antiserotonergic antipsychotics in minimally sufficient dose levels yielded favourable effects. Adding serotonergic antidepressants or mood stabilizers resemble augmentation approaches. In perspective, individual psychotherapeutic and pharmacological strategies have to be further evaluated. Head to head trials of different approaches as well as combinations of the mentioned strategies promise therapeutic progress and will help to improve treatment options for schizophrenia patients suffering from comorbid OCS.
