Mild Cognitive Impairment
by Cynthia M. Johnson, MA
Mild cognitive impairment (MCI) is a loss in memory. It does not get in the way of day-to-day tasks but can make it hard to make decisions and use language. MCI may raise the risk of getting dementia and Alzheimer disease later in life.
The causes are not clear. It may be caused by early brain changes of dementia or Alzheimer disease.
MCI is more common in people over 65 years of age. Things that may raise your risk are:

There are no medicines that have been shown to help MCI. Some people may be given cholinesterase inhibitors to treat changes in thinking.
