Mild cognitive impairment

This involves a notable decline in at least one area of thinking skills, such as memory, that's greater than the changes of aging and less than those of dementia. Having mild cognitive impairment doesn't prevent you from performing everyday tasks and being socially engaged.

Researchers and physicians are still learning about mild cognitive impairment. For many people, the condition eventually progresses to dementia due to Alzheimer's disease or another disorder causing dementia.

Other people's memory loss doesn't progress much, and they don't develop the spectrum of symptoms associated with dementia.
