Somewhere between misplacing your keys, missing an important appointment, or forgetting an acquaintance’s name and developing a full-blown case of dementia is a condition researchers call mild cognitive impairment (MCI).
MCI is cognitive decline beyond what you would expect to see in a person based on normal aging and other factors. It may be an early signal for the future onset of dementia, or it could be a temporary reaction to an underlying disease or even be stress related. In the latter cases, MCI would most likely either reverse itself or remain stable.
