[Ethnic features of multipathology in elderly and senile patients of the Republic of Sakha suffering from chronic brain ischemia].

OBJECTIVE To study ethnic characteristics of multipathology in elderly and senile patients with chronic cerebral ischemia living in the Republic of Sakha (Yakutia). MATERIAL AND METHODS The study included 522 inpatients, aged 60 to 89 years, who were divided into subgroups depending on the stage of chronic cerebral ischemia, ethnicity (Evens, Yakuts and Russians) and age (elderly and senile). RESULTS In addition to vascular cerebral pathology, comorbidities were identified in patients of older age groups. At the same time, polymorbidity was less pronounced in the Evens, the indigenous inhabitants of the northern regions of Yakutia, than in the Yakuts and representatives of the non-indigenous population - Russians. CONCLUSION The relatively rare occurrence of comorbid pathologies in Evens is presumably associated with greater adaptation to the extreme climatic conditions of the North.
