London: Scientists have found that nicotine patches help improve the memory of elderly people experiencing the earliest symptoms of dementia, a finding they say could lead to effective use of nicotine to treat people with mild cognitive impairment. However, experts said the results of the small study are not conclusive, merely hinting of a benefit and do not mean people should smoke. Scientists have known for some time that the brain contains receptors that respond to nicotine and that a number of these are lost in Alzheimer`s. In the latest study, a team at the Vanderbilt University School of Medicine in Nashville looked at 67 elderly people with "pre-dementia" or mild cognitive impairment (MCI) andtreated them with nicotine patches that deliver the addictive chemical found in cigarettes. After six months of treatment, the researchers performed on the patients tests designed to assess memory, attention and response times. It was found that the nicotine-treated group regained 46 per cent of normal performance for age on long-term memory, whereas the placebo group worsened by 26 per cent over the same time period, the BBC reported.
