[Study of the performance of complex activities of daily living in a population of patients with mild cognitive impairment. Mild functional impairment: A new clinical entity?]

Abstract

Several papers describe functional changes in the aging population, and its relevance in the early cognitive impairment detection. Alterations in instrumental activities would constitute a diagnostic marker of MCI and predict the progression to Dementia. In order to count on a tool to evaluate the performance in the use of new technologies we have designed a new protocol, Complex Functional Study (CFS), that quantifies performance and functional changes Related to previous states.

Objectives: To compare CFS scores in patients with MCI with a control group without cognitive impairment (CD) and verify their diagnostic performance to detect complex function alterations in reference too the functional scales, Instrumental Activities of Daily Living (AVDI) and Disability Assessment for Dementia (DAD).

Methods: Patients with MCI and controls were included. All subjects were evaluated with a neurocognitive battery, and functional scales (EFE).STATA software version 14.2 was used for data analysis.

Results: 269 recruited patients older than 65 years old, 173 with diagnosis of MCI and 96 controls. The MCI patients obtained significantly higher EFE scores tan subjects without DC (p < 0,001).The EFE presented a greater sensitivity to detect the functional alteration (EFE 81.5%, AVDI 25.9%, DAD 18.5%).

Conclusions: The EFE is an instrument of optimal clinical value, with good sensitivity to identify the alteration of the complex activities of daily life in patients with MCI. The results allow to characterize a profile compatible with Light Functional Impairment.
