Body weight was examined in chronic schizophrenic patients. Underweight
medicated patients had normal ventricular brain ratios (VBRs) on CT.
Overweight patients had both normal and abnormal VBRs. Weight decreased
during neuroleptic withdrawal; caloric intake and weight increased when
neuroleptics were reinstituted. Weight gain on neuroleptics correlated with
symptom improvement independent of VBR or gender. Weight changes and
psychosis in schizophrenia may be mediated by similar neurochemical
systems.Abstract Teaser
