Arteriosclerosis, infarcts, and dementia

D P Birkett, A Raskin

    Journal of the American Geriatrics Society
    |April 1, 1982

    Summary
    This summary is machine-generated.

    In elderly patients with late-onset mental disorders, cerebral infarcts are strongly linked to cerebral arteriosclerosis. This finding supports a causal relationship, particularly relevant for understanding multi-infarct dementia.

    Area of Science:

    • Neurology
    • Geriatrics
    • Pathology

    Background:

    • Elderly patients with late-onset mental disorders often present complex neuropathological findings.
    • Distinguishing between cerebral infarcts and senile brain disease is crucial for diagnosis and treatment.

    Purpose of the Study:

    • To investigate the relationship between cerebral infarcts and cerebral arteriosclerosis in elderly patients with late-onset mental disorders.
    • To compare the prevalence of arteriosclerosis in patients with infarcts versus those with senile brain disease.

    Main Methods:

    • Autopsy examination of 31 brains from elderly mental-hospital patients.
    • Macroscopic assessment of arteriosclerosis, including base of brain and arterial plaques.
    • Statistical analysis using Fisher's exact test and chi square.

    Main Results:

    • 14 brains showed cerebral infarcts without senile brain disease; 10 showed senile brain disease without infarcts.
    • Overwhelming preponderance of arteriosclerosis found in patients with cerebral infarcts compared to those with senile brain disease.
    • Cerebral arteriosclerosis was significantly associated with cerebral infarcts.

    Conclusions:

    • Cerebral infarcts in elderly patients with mental disorders are closely and causally related to cerebral arteriosclerosis.
    • This association has significant implications for the understanding and diagnosis of multi-infarct dementia.
    • Cerebral arteriosclerosis is a key factor in the etiology of infarcts leading to cognitive decline in the elderly.
