Neuropsychological Functioning in Older Adults with Mild Cognitive Impairment and Insomnia Randomized to CBT-I or Control Group

Abstract

Objectives: Improving the sleep of older adults with mild cognitive impairment (MCI) represents a first step in discovering whether interventions directed at modifying this risk factor also have the potential to alter the cognitive decline trajectory. Methods: A six-session, adapted version of a cognitive behavioral therapy for insomnia (CBT-I) was administered to older adults (N = 28; 14 per group) with MCI across two residential facilities. Participants were randomly assigned to either the sleep intervention or an active control group and completed a neuropsychological battery at three time points (e.g., baseline-T1, post-intervention-T2, 4 month follow-up-T3). Results: Results showed a significant improvement in sleep and a change (p
