title: [The morphology of pial and cortical vessels in senile dementia].
abstract: The presentation deals with the data of a morphological study on the brain vessels in senile dementia (19 cases) which are compared to the corresponding data of mentally healthy individuals of different ages. It was displayed that in the arterial vessels along with collagenous and elastic fibres there were pseudoelastic structures subjected during the involutional process to hyperplasy. The author found that the inner elastic membrane did not undergo pathological changes either in the involutional process, or in the cerebral congophyl angiopathy, which was characteristic of senile dementia. It was established that primary hyalinosis (artheriosclerosis), characteristic of the vessel involution of some organs was not observed as an independent process in the brain. A constant combination of hyalinosis and amiloidosis in the same vessels allowed the author to suppose that the two processes were of the same genesis in senile dementia.
