Explanation of the study: As the older adult population continues to rise, so will normal cognitive aging. This increase raises concern for maintaining cognitive function and possibly delaying the onset of disorders such as dementia. Cognitive training (CT) is one potential solution which may be done using computer programs, pencil-and-paper problem solving activities, or everyday tasks. Traditional, skilled occupational therapy (OT) is not reimbursed for this type of preventative or maintenance services. CT may be a fundable answer for older adults to maintain or even improve cognitive function. The purpose is to determine if computerized CT, utilizing a specific program (RehaCom), improves executive functioning in the older adult with mild cognitive impairment, as compared to pencil-and-paper CT.
