Improving Mobility and Cognition in Older Adults Using Non-Invasive Brain Stimulation

NCT ID: NCT02740530


Title
Improving Mobility and Cognition in Older Adults: Establishment of an Interdisciplinary Clinical Research Program Using Non-Invasive Brain Stimulation
Purpose
This study aims to test the efficacy of a type of non-invasive brain stimulation (NIBS), known as repetitive transcranial magnetic (rTMS) stimulation, in improving mobility, particularly gait stability and variability, and executive dysfunction in older adults. The study will be conducted in forty older adults (≥60 years) with a diagnosis of executive dysfunction.
Details
The proposed study using rTMS will build upon the investigators previous work demonstrating the link between cognitive impairment, particularly executive dysfunction, and mobility/gait abnormalities in older adults, even in those labeled as "cognitively normal". Emerging evidence demonstrates that executive dysfunction is an early phenomenon in the pathway to mobility disability and subtle changes in executive function are independently associated with future falls. The investigators have piloted studies showing that pharmacological enhancement of executive function, can improve gait-motor performance and, potentially, reduce mobility decline and risk of falls. This supports the rationale for a promising intervention: enhancing cognition to prevent mobility decline and reduce risk of falls. The long-term goal is to create a clinical research program to apply rTMS as an early novel intervention for cognitive/motor interaction to ultimately delay the onset of cognitive and mobility disabilities and their devastating consequences, dementia and falls, in older adults. However, it is first necessary to study a smaller group of seniors to plan for recruitment, study retention and compliance, and to gather preliminary data as proof of principle before proceeding to a larger clinical trial.
