Abstract

Population aging is today an universal phenomenon. The increase of the elderly population is associated with larger prevalence of dementia. Elderly people constitute 9,6% of all Brazilians and dementia is one of the most prevalent morbidity, with estimated prevalence of 2% to 25% ou ranging from 2% to 25% in those aged 65 years or more. Parallel to the cognitive impairment that happens with the aging, we verify a higher incidence of non transmissible chronic diseases, such as chronic kidney disease (CKD), hypertension, and diabetes mellitus. Of particular interest is CKD, since its prevalence is increasing worldwide, it is considered a world health problem, its diagnosis among the elderly population is very high, what explains the high mean age of patients in renal replacement therapy. The depression and the cognitive impairment constitute two of the most prevalent diseases in geriatrics. It is not uncommon that they come together, and sometimes, one simulates the other, what makes the diagnosis very difficult. Depression is quite common among patients with CKD, but its causes are still not known. In this study, we aim to assess the cognitive function ,depression and life quality in patients of different from the chronic renal disease.
