By Mayo Clinic staffMild cognitive impairment (MCI) is an intermediate stage between the expected cognitive decline of normal aging and the more pronounced decline of dementia. It involves problems with memory, language, thinking and judgment that are greater than typical age-related changes. If you have mild cognitive impairment, you may be aware that your memory or mental function has "slipped." And your family and close friends may also notice a change. But generally these changes aren't severe enough to interfere with your day-to-day life and usual activities.
Mild cognitive impairment increases your risk of later developing dementia, including Alzheimer's disease, especially when your main difficulty is with memory. But some people with mild cognitive impairment never get worse, and a few eventually get better.
