title: Neurodynamics of abnormalities in cerebral metabolism and structure in schizophrenia.
abstract: Much evidence points to the importance of intrauterine events in the etiology of schizophrenia and suggests a complex interplay between dysfunctional and intact neurons in the pathophysiology of the disorder. This article contrasts what is known of the topographies of metabolic and structural brain abnormalities in schizophrenia at differing stages of the illness. From these contrasts, a schema is elaborated by which subtle neurodevelopmental perturbation in early to middle gestation might give rise to functional and structural abnormalities that ultimately release the diagnostic symptoms of schizophrenia. An interaction between those mechanisms mediating the expression of psychosis and the initially subtle stages of normal aging is posited to act on the substrate of a brain that is already developmentally compromised. Such a process might masquerade as "progression" in the absence of any active disease directly attributable to the original etiological event.
