RESUMO
Objective To investigate the leukoaraiosis(LA)influencing factors of sleep disorder patients. Meth-ods 90 cases of LA patients which were conformed MRI diagnostic criteria were chosen as LA group,90 cases of normal old people which the gender and age were matched with LA group were chosen as NC group;by asking the medical history to inquirying blood vessel hazards;pittsburgh sleep quality index(PSQI)was adopted to evaluate the condition of sleep disorders,according to the performance MRI of skull to part LA group as four grades. Results In LA group,hypertension and diabetes incidence were significantly higher than that in group NC(P < 0. 05);LA group,PSQI score was significantly higher than that of NC group(P < 0. 01). LA group with the LA increasing grade,PSQI score increased(P < 0. 05). Regression analysis showed that age,hypertension,diabetes and MoCA were associated with LA in patients with sleep disorders. Conclusion Patients with LA have a sleep disorder, which is closely related with the degree of cognitive impairment,LA lesions,age,hypertension,diabetes etc.
