Filter by:This research is being done to find out if daily use of the drug levetiracetam can improve memory function in individuals with memory problems like those associated with Mild Cognitive Impairment (MCI) and Alzheimer's disease (AD).
Compared with cognitively normal older adults, those with mild cognitive problems (MCI) have a two-fold higher rate of falls, sustain more fractures, and have a higher rate of mortality due to falls. Why older adults with cognitive problems fall more frequently is not completely understood. What is known, however, is that attention is a necessary cognitive resource for normal walking and impairments in attention are associated with increased risk of falls in older adults. It has been suggested that cholinesterase inhibitors (ChEI), medications used for treatment of dementia, may improve motor function and walking (gait performance). Since ChEI are known to improve attention, we hypothesized that ChEI will reduce falls risk in people with MCI by improving their gait velocity, improving their balance, and reducing their gait variability; a well-established risk factor for falls. In the proposed study, we will evaluate the effect of donepezil (ChEI) on gait velocity, gait variability, and the balance on 140 elderly individuals with MCI (70 intervention and 70 controls). Gait variables will be measured using an electronic walkway, and balance confidence using a validated scale (Activities-Specific Balance Confidence Scale; ABC) over four months. By characterizing and understanding the effects of cognitive enhancers on fall risk in older adults with cognitive impairments, we will be able to pave the way for a new approach to fall prevention in this population. We would establish that medications that augment cognitive function could be a complementary therapeutic option for reducing fall risk in people with MCI. This may lead to new approaches to prevent and treat fall risk in this population, which will lead to improve the autonomy and quality of life of seniors in early stage of dementia, and a decreased burden for the Ontario health care system.
