Influencing factors of dysmnesia in elderly cerebral infarction patients

ObjectiveTo investigate the incidence and influential factors of dysmnesia in elderly patients with cerebral infarction and to provide evidence for intervention on the disease. MethodsTotally 429(241 males,188 females)elderly hospitalized patients with cerebral infarction aged 60 to 80 years were recruited from neurology department of a hospital from April 2010 to October 2011.Rivermead Behavioural Memory Test(RBMT-Ⅱ)was adopted to assess memory function of the patients. ResultsIn the patients,there were 342 diagosed as dysmnesia,with 99(23.1%) mild dysmnesia,187(43.6%) moderate dysmnesia,56(13.0%) serious dysmnesia,and a overall prevalent rate of 79.7%.Univariate analysis showed that old age,female,lower educational background,employment,hypertension,hyperlipemia and diabetes mellitus,relapse of the disease,and with infarction of temporal lobe,frontal lobe,thalamus or basal ganghia were significant risk factors for the incident of dysmnesia(P<0.01 or P<0.05).Multivariate logistic regression analysis showed that risk factors for dysmnesia were female,hypertension,diabetes mellitus,and relapse of the infarction,and the protective factors were high educational background and with occupation of brainwork. ConclusionThe influential factors of dysmnesia in elderly cerebral infarction patients are complex and more attentions should be paid to these factors.
