[Multi-infarct dementia in the very elderly].

Findings regarding the multi-infarction dementia in 34 long-lived persons from Sofia aged 92.4 years on average are introduced. The patients were observed until they died. Three clinical variants of multi-infarction dementia have been found (the lacunar variant, the amnestic variant, and the pseudoparalytic variant). The clinical peculiarities of the disease are stronger pronounced with physically active long-lived patients. In the terminal stage the patients approached the vegetative state. It is justified to speak of an unfavourable course of multi-infarction dementia in long-lived people.
