Studies of brain morphology in schizophrenia may be informative about
basic pathophysiologic processes, provide clinically useful indicators
of treatment response, and lead to the identification of markers for
selective treatment effects. This paper reviews findings from magnetic
resonance imaging studies of patients with schizophrenia conducted at
Hillside Hospital, with special attention to (1) findings that have h
elped distinguish patients who respond well to typical neuroleptics fr
om those who have gone on to trials of clozapine, (2) the capacity of
morphological measures to predict clozapine treatment response, and (3
) the possibility that selective hypertrophy of striatal structure may
be caused by chronic treatment with typical neuroleptics, but not by
clozapine.
