Mild cognitive impairment (MCI) is an intermediate stage between normal cognitive function and dementia. The rate of progression of MCI to dementia in older adults has been found to be between 10-12% per year, whereas those without cognitive impairment acquire dementia at a rate of only 1-2% per year. MCI has been linked to poor dual-tasking, impaired balance and functional mobility, and is a significant risk factor for falls. Individuals with MCI need preventive therapies that target both the cognitive and mobility-related outcomes. Dr. Jehu has identified pairing targeted dual-tasking training with balance and mobility training as a promising  preventative therapy.

In recent research, balance and mobility training (BMT), and balance and mobility plus cognitive training (BMT+C) programs have been shown to improve dual-tasking and functional mobility in the healthy older adult population; however no previous interventions have targeted dual-task training in individuals with MCI. Dr. Jehu will extend this work to individuals with MCI in order to improve cognitive and mobility outcomes. The BMT and BMT+C interventions will determine whether individuals with MCI can reverse cognitive and functional declines and improve to healthy older adult norms.

The timed up & go (TUG) is a commonly used clinical functional mobility assessment tool. TUG has been shown to be an independent predictor of cognitive decline following an ischemic stroke, and has accurately differentiated between healthy older adults and older adults with MCI. Dr. Jehu aims to use TUG to improve the diagnostic interpretation of important clinical measures used to evaluate individuals with MCI.

Dr. Jehu’s research may serve to improve the interpretation of clinical diagnostic tools, which could revolutionize the prescription of exercise in older adults with MCI and improve the overall interpretation of commonly used clinical assessment tools.
