Details and patient eligibility

About

This research is being done to determine if computerized administered cognitive fitness activities will improve thinking and depression in older depressed adults who are being treated with antidepressants. The investigators are also interested in whether participating in the treatment will result in changes to brain activity measured with magnetic resonance imaging (MRI).

Full description

Major depression in the elderly is both challenging to treat and detrimental to the cognitive functioning of patients. Major depression increases the probability of a later dementia diagnosis. By targeting cognitive processes in treatment, the investigators hope to both find a more effective means to manage major depression in older adults, but also demonstrate how top-down processes (e.g., Executive Control Network) may be driving depression and cognitive decline in older adults.

The investigators are recruiting older adults with and without mild cognitive impairment. All subjects must have at least mild depressive symptoms to be eligible to participate. Subjects will be randomly assigned to one of two different interventions.

Results of this study will help the investigators understand the mechanisms that contribute to depressed mood and cognitive change in older adults with late life depression.

38 participants in 2 patient groups

Computerized Cognitive Remediation of Executive Functioning (CCR-EF)

Experimental group

Description:

Initially 10 hours of processing speed exercises from "Brain HQ", (the 3 exercises are auditory tone sweep, visual processing \[Double Decision\], visual sweep). Following the 8-10 hours of Brain HQ, participants complete 8-10 hours of "Ultimate Word Master" before completing 16-20 hours of "Neurogrow" (formerly called "Catch the Ball"). Participants are asked to complete approximately 28-42 hours of computerized brain training over 4-6 weeks.

Treatment:

Other: Computerized Cognitive Remediation of Executive Functioning (CCR-EF)

Active Control

Active Comparator group

Description:

Patients in the active control arm will complete three activities according to a standard protocol: 1) play a visuospatially oriented computer game (Myst), 2) watch computer-based educational programs on art, history, literature, and 3) play computer games online through the Brain HQ platform; games include crossword puzzles, soduko, paddleboard, and word search. Participants will complete a total of 32-42 hours of training over 4-6 weeks. Time spent on each task will be evenly divided (15 minutes of each task everday).

Other: Active Control
