[Quality of life in Alzheimer's disease]

Abstract

Introduction: Quality of life is a concept that is receiving increasing amounts of attention; its assessment complements the traditional clinical evaluation, which is of special interest in areas related with healthcare organisation. Here, we present a study on quality of life in Alzheimer's disease and its relationship with cognitive and functional measures.

Patients and methods: Quality of life was evaluated by means of the EQ-5D scale in a sample of cases of Alzheimer's disease (diagnosed according to criteria established by the National Institute of Neurologic, Communicative Disorders and Stroke-Alzheimer's Disease and Related Disorders Association) that donated blood samples for the National DNA Bank. The status of the global deterioration scale was determined and a verbal fluency test and the Folstein minimental test were also carried out. A classic analysis, variable contrast by means of chi-square for proportions and Student's t test for measurements were conducted, as well as estimation of r for the regression models in the quantitative variables. The social rate was determined using the software application SPSS v. 11.

Results: Altogether 141 cases were analysed, with a male to female ratio of 2:1, and a mean age of 76.2 years. Aspects such as personal hygiene, activity and, to a lesser extent, motility are affected in Alzheimer's disease, but pain and anxiety aspects do not seem to be affected. There is a relationship between quality of life, functional scales and cognitive scales. Functional aspects correlate with quality of life better than cognitive ones.

Conclusions: Quality of life is evaluated in Alzheimer's disease using general scales, such as EQ-5D. Cognitive aspects do not appear to provide relevant information about quality of life that is not already provided by the functional aspects.
