Perception of functionality in mild and moderate stages of Alzheimer's disease: vision of the patient and their caregiver

OBJECTIVES: Evaluate and compare of the perception of functionality in elderly with Alzheimer´s disease (AD) with the functionality they present according with the perception of their caregivers, as well as evaluate this relationship according to the degree of cognitive problems in this population METHODS: Cross-sectional study in 20 older people with AD and their caregivers, applying the Functional Independence Measures (FIM) to evaluate the perception of functionality according to the report of the elderly with AD and their caregiver; it was used the Clinical Dementia Rating Scale (CDR) to evaluate the clinical staging of the dementia, considering elderly with mild AD (CDR 1) and moderate AD (CDR 2). RESULTS: When comparing the perception of the functionality of the total sample of older person with AD and their caregivers, the mean of FIM was 116.5 (sd=9.8) points, reported by patients with AD, and mean of 88.5 (sd=19.0) points according to their caregivers (p<0.001). The same pattern was observed in the comparison between the elderly with mild AD and their caregivers, although self-care and mobility FIM's items have not been statistically significant. In the elderly with moderate AD, there were significant differences in all dimensions of the FIM, when compared to their caregivers. CONCLUSION: Older patients with AD underestimate their difficulties as compared to the perception of their caregivers and this perception of functionality is worse according with progression of AD.
