Computer Presented and Physical Exercises to Maintain Cognitive Function and Emotional Health in Older Adults

Yale University34 enrolled

Overview

The aim of this study is to investigate and compare how 18-weeks of computer-based brain training and physical exercise together can improve physical performance, cognitive function and mood in older adults in a cross-over design with participants randomized to receive the intervention first and then be assessed before and after an 18 week period without intervention, or the reverse sequence. 80 adults between the ages of 65 and 105 years old will be invited to participate. After providing informed consent, in the case of subjects who are living on units for individuals with memory or other cognitive compromise, after assent from the individual and approval from facility staff, subjects will be randomly assigned to either receive the intervention for 18 weeks and then be followed for an additional 18 weeks, or to be followed for 18 weeks without intervention and then do the intervention for 18 weeks. The intervention will consist of 18 weeks of 60-minute PE sessions 3-4 times/week and 25-minute CBB training sessions 3-4 times a week. There will be 3 assessments of participants: before and after the first 18-week period and then again after the second 18-week period. Assessments will be done in 2 sessions over a total of 90 minutes and will include demographic, health, physical activity and social activity questionnaires as well as the self-report measures of cognitive function, emotional state and weekly activities; quantitative assessments of physical balance, strength, flexibility blood pressure and heart rate; and tests of cognitive function. Subject medications will be recorded at each assessment. The wait-list control group will receive the same assessments at the same time points.

Outcomes

Primary Outcomes

Composite cognition score

Composite from: Flanker Test of Attention; Go/No-Go Test of Response Inhibition; List Sort Working Memory Test; Logical Memory Story Recall; Digit symbol coding; Digit Span Forwards and Backwards; Hopkin's Verbal Learning Test; Trail Making B; Stroop Color Word; Category Verbal Fluency; Reaction Time. A composite score will be calculated for each participant at baseline and after training and waitlist periods by first determining Z-scores for each test for each participant at each time point based on means and standard deviations for the entire sample at baseline, and then averaging the individual's Z-scores at that time point.

Time frame: 18 weeks

Sit to Stand in one-minute

Number of times able to go from sit to stand in in one minute

Time frame: 18 weeks

Balance - stand on one foot at a time

Stand on one foot with the toe of the other foot touching the calf of the standing leg - number of seconds able to maintain. The sum of right and leg foot will be added.

Time frame: 18 weeks

Mood and Quality of Life

Composite score from WHODAS, DEMQ QLI and Beck Depression Inventory. A composite score will be calculated for each participant at baseline and after training and waitlist periods by first determining Z-scores for total score on each questionnaire for each participant at each time point based on means and standard deviations for the entire sample at baseline, and then averaging the individual's Z-scores at that time point.

Time frame: 18 weeks

Secondary Outcomes

Attention and Speed of Processing

Flanker Test of Attention (average reaction time on correct incongruent trials)

Time frame: 18 weeks
