To date there are no simple or effective methods that can determine whether a person who has MCI will go on to develop Alzheimer's. There is no specific treatment for MCI but there are indications that symptoms may be relieved by medication used for mild to moderate Alzheimer's.

Family members and loved one's have a role in encouraging self-help. All the evidence suggests that a person's lifestyle can have a marked effect on cognitive capabilities and can help prevent Alzheimer's. For example, physical exercise, good diet, maintaining social contacts, doing crossword puzzles and learning a new language, are all associated with maintaining and even developing cognitive capabilities. Memory lapses can fairly readily be compensated for by use of calendars, diaries or other tools to help things along. This can provide a big boost to confidence, increase the person's sense of independence, and provide a continued sense of value within their family and community.
