Extract

IQ, appears to play a major role in the development and course of schizophrenia. Patients with low IQ tend to have an earlier onset (Pollack, 1960; Belmont, Birch, Klein and Pollack, 1964; Offord and Cross, 1971), to stay in hospital longer (Offord and Cross, 1971) and improve less while there (Pollack, 1960), to remit less often (Stotsky, 1952) and to make a poorer post-hospital adjustment (Pollack, Levenstein and Klein, 1968) than patients with normal or high IQ. In addition, schizophrenics, particularly the men, tend to have lower childhood IQs than their siblings (Lane and Albee, 1965; Offord, 1974).
