View clinical trials related to Mild Cognitive Impairment (MCI).
Filter by:The purpose of this study is to build upon the information obtained in the original Alzheimer's Disease Neuroimaging Initiative (ADNI1) and ADNI-GO (Grand Opportunity; a study funded through an NIH grant under the American Recovery and Reinvestment Act), to examine how brain imaging technology can be used with other tests to measure the progression of mild cognitive impairment (MCI) and early Alzheimer's disease (AD). ADNI2 seeks to inform the neuroscience of AD. This information will aid in the early detection of AD, and in measuring the effectiveness of treatments in future clinical trials.
The purpose of this study is to learn if activities that challenge the brain (mentally stimulating activities) can improve memory and other types of thinking in patients with Mild Cognitive Impairment. The study will compare the effects of different methods of mental stimulation.
Age-related cognitive decline is unavoidable. However, recent results of neuroplasticity-based research show that neuroplasticity-based training and physical activity might have the potential to decelerate or even reverse effects of aging and age-related cognitive impairments. Little is known whether these results also apply to pathological processes of aging such as mild cognitive impairment (MCI) and dementia. This multi-center study aims at investigating efficiency and feasibility of a neuroplasticity-based auditory discrimination training and a physical fitness training for patients suffering from mild cognitive impairment or mild Alzheimer's disease (Mini Mental State Examination, MMSE > 19). Evaluation will include neuropsychological testing, electroencephalography (EEG) and magnetic resonance imaging (MRI) measurements as well as blood and liquor analyses.
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.
Recent studies have described the role of melatonin as a sleep regulator and as an anti- oxidative neuroprotective agent in improving sleep quality and delaying cognitive decline in Alzheimer's disease (AD). In accordance with this data, our hypothesis is that melatonin will delay the cognitive decline in Mild Cognitive Impairment (MCI) patients and reduce the conversion rate from MCI to AD.
