The purpose of this study is to determine whether nicotine can improve symptoms of memory loss in people experiencing mild memory problems (mild cognitive impairment).
Recent studies have suggested that one of the causes of memory disorders may be a reduction in a particular chemical substance in the brain. This chemical substance, acetylcholine, is thought to act on certain brain cells in a specific way that helps us to remember and use memories as well as affect our mood.
In people with mild cognitive impairment (and Alzheimer’s disease), the level of acetylcholine may be changed, and this may impair brain functioning. Preliminary studies have suggested that short-term administration of nicotine appears to improve memory in patients with mild memory loss and early Alzheimer’s disease (AD). It has been known for many years that nicotine imitates many of the actions of acetylcholine.
By administering a nicotine patch over a longer period of time to participants with MCI, we hope to better understand whether nicotine may act to improve memory loss symptoms over the longer term and whether it may help to delay the progression of memory loss symptoms.
The amount of nicotine in each patch used in this study is the same as patches that are used in people who are trying to quit smoking and has not been associated with nicotine dependence.
