Mild cognitive impairment affects memory to the point of being noticeable to others, but not enough to interfere with daily functioning. People with mild cognitive impairment exhibit some forgetfulness or amnesia of recent events. They often need to write notes to remind themselves to do things that they would otherwise forget. They still can however, perform daily tasks such as paying bills or taking medications without direction from others.

While people with mildly impaired memory can function relatively normally, the condition is of concern because nearly half of these patients develop Alzheimer's disease within five years.
