title: The neuropathology of schizophrenia.
abstract: Insofar as schizophrenia is a neuropsychiatric syndrome involving the brain, neuropathology is a promising, if not essential investigative approach. Although traditional neuropathology has yet to yield a pathognomonic lesion in schizophrenia, there have been no shortages of findings. Unfortunately, many of these findings have not only failed to be pathognomonic, but they have not been consistently replicated. Fortunately, newer neuropathological techniques, such as post-mortem neurochemistry, have resulted in findings among the most reproducible in schizophrenia research. Although one of these, increased dopamine receptors in the basal ganglia of schizophrenic patients, has been replicated many times, it suffers from doubts as to its clinical relevance. Are these increases in dopamine receptors primary to the illness or a side effect of the treatment? This article discusses the relevance of this finding, reviews other highlights of post-mortem neurochemistry and traditional neuropathology, and discusses new horizons such as autoradiography, immunocytochemistry, and neuronal morphometrics.
