[Angioarchitectonics of the cerebral cortex in senile dementia as the basis of hemodynamic disorders].

Using Klosovsky's technique and scanning electron microscopy, the authors studied the angioarchitectonics of the cerebral cortex in 3 patients with senile dementia and in mentally normal age-matched individuals. Senile dementia was associated with characteristic loop- and spiral-shaped changes in vascular trunks. Possible causes of these phenomena and their relationship to the cerebral blood flow is discussed.
