Cerebellar pathology in schizophrenia: a controlled postmortem study

D R Weinberger, J E Kleinman, D J Luchins

    The American Journal of Psychiatry
    |March 1, 1980
    PubMed
    Summary

    Schizophrenia patients often show smaller cerebellar vermis areas. This morphometric study confirms structural abnormalities in the cerebellum, supporting existing research in living patients.

    Area of Science:

    • Neuroanatomy
    • Psychiatric Research
    • Morphometrics

    Background:

    • The cerebellum plays a role in cognitive and emotional functions.
    • Previous research suggests potential cerebellar abnormalities in schizophrenia.

    Purpose of the Study:

    • To investigate morphometric differences in the anterior cerebellar vermis in individuals with schizophrenia.
    • To correlate post-mortem findings with in-vivo imaging studies.

    Main Methods:

    • A morphometric analysis was conducted on the anterior cerebellar vermis.
    • The Yakovlev collection, comprising 47 brains, was utilized.
    • Comparative analysis included brains from schizophrenic patients, healthy controls, and patients with other psychiatric diagnoses.

    Main Results:

    • A significantly smaller anterior cerebellar vermis area was observed in 5 out of 12 brains from schizophrenic patients compared to controls (p < .02).
    • This finding was consistent across different control groups.
    • Results align with previous computerized tomography scan observations in living individuals.

    Conclusions:

    • Structural abnormalities of the cerebellar vermis are present in some individuals with schizophrenia.
    • These findings support the hypothesis of cerebellar involvement in the pathophysiology of schizophrenia.
    • Morphometric studies of post-mortem brains provide valuable insights into neurobiological alterations in psychiatric disorders.
