Cerebral amyloid angiopathy in the elderly

|April 1, 1981
Summary
Cerebral amyloid angiopathy (AA) increases with age, affecting women more. This condition, linked to amyloid deposits, can cause cerebral bleeding and cortical infarctions in the aged.
Area of Science:
- Neuropathology
- Gerontology
- Vascular Biology
Background:
- Cerebral amyloid angiopathy (AA) is a common finding in the aging brain.
- Its relationship with other cerebrovascular lesions requires further investigation.
Purpose of the Study:
- To determine the relationship between cerebral amyloid angiopathy (AA) and other cerebrovascular lesions in the aged population.
Main Methods:
- Examination of 128 autopsy brains from individuals over 60 years of age.
- Utilized both light and electron microscopy for detailed analysis.
Main Results:
- Cerebral AA frequency increased with age, reaching 58% in those over 90.
- AA was more prevalent in women and often associated with senile plaques.
- Amyloid deposits in vessel walls led to structural damage, hyalinosis, angionecrosis, and fibrotic occlusion.
- Severe AA was linked to cerebral bleeding and small cortical infarctions, particularly in the temporal lobes.
Conclusions:
- Cerebral amyloid angiopathy is a progressive condition in the aged, associated with significant cerebrovascular damage.
- AA contributes to cerebral bleeding and infarctions, highlighting its clinical significance in elderly patients.
