Everyone would like to improve their memory. Just as exercise trains the body, answers but he did allude to the it may be possible to design a “fitness program” for our memory. This is especially important for individuals suffering from mild cognitive impairment (MCI). MCI is defined as impaired memory performance in older adults without general cognitive impairment or dementia. MCI is important because individuals with this disorder are much more likely to develop dementia over a 2-3-year period than the general population.
It is hoped that interventions aimed at MCI may improve quality of life for these absolutely no choice is aging.
individuals and even slow down the development of Alzheimer’s Disease. In a recent paper in Dementia and Geriatric Cognitive Disorders, Drs. Sylvie Belleville, Brigitte Gilbert, Francine Fontaine, Lise Gagnon, Édith Ménard, and Serge Gauthier reported that healthy older adults and individuals with MCI showed improvement in face-name associations and memory for lists after completing an 8-week cognitive intervention program aimed at improving memory, attention, and stress management. In contrast, those subjects who did not receive the memory training showed no improvement over the same time period, and MCI patients even showed a small decline. What is especially exciting about these results is that the memory improvement seen in subjects with MCI was on memory tasks that are known to deteriorate in Alzheimer’s Disease patients. This provides some hope that even brief memory training courses may be useful for MCI sufferers and maybe even reduce the chances of developing dementia later on. But since healthy older adults also showed memory improvement, a little memory workout is probably good for everyone. Now, everybody Reference:
