Assessment of cognitive and affective disorders in an elderly population undergoing hemodialysis.
The purpose of this study was to assess the prevalence of cognitive and affective disorders in a group of elderly people suffering from chronic renal failure (CRF) and undergoing outpatient hemodialysis. Psychogeriatric assessment was performed on 39 individuals over 65 years of age suffering from CRF, and on a control group composed of 35 healthy elderly individuals. Assessment was made through Mini Mental State Examination (MMSE), Geriatric Depression Scale (GDS), Activity Daily Living (ADL) and Instrumental Activity Daily Living (IADL) shortly before hemodialysis. A number of blood parameters were determined for both groups to evaluate the state of metabolic compensation. The elderly people undergoing hemodialysis did not seem to present a greater decline in cognitive capacity than their healthy peers, even if this is closely related to the level of anemia present in hemodialysis patients. On the other hand, affective disorders were widely observed, although in mild form, and seem to depend on factors other than age. There is certainly a reactive element deriving from the hemodialysis condition itself and the problems related to it, whereas an organic element linked to CRF cannot be excluded, and which seems to be related to anemia. Finally, the level of independence does not seem to be compromised in hemodialysis patients.
