[Changes of orbitofrontal astroglia in senile dementia (author's transl)].

The changes of orbitofrontal studied astroglia in 10 cases of senile dementia have been studied. The modification of Golgi-method by Bubenaite was used. The results reveal 4 different types of changed astroglia. A relation between changes of makroglia and the aging process of CNS is suggested. The changes of glia are not a result of nervous cell alterations, but an independent neuroglial process under the conditions of aging.
