Supervised by: Atsushi Iwata, Associate Professor, Department of Neurology, Graduate School of Medicine, University of Tokyo

At present, in the so-called super-aging society, one in four elderly people aged 65 years or older are said to have MCI or dementia.

While public concern about dementia is increasing day by day, many people would say “I have heard the words “mild cognitive impairment,” but I do not know about it well enough.”

Therefore, this section, entitled “Learn about mild cognitive impairment (MCI),” attempts to provide a clear explanation about MCI.

Early detection of MCI is important.

MCI is said to be the condition that prevails “immediately prior to dementia.” Although patients with MCI have memory impairment, like forgetfulness in dementia, the symptoms are still mild and they are able to live independent lives, because they do not have dementia.

Precisely because the symptoms are mild, family members and the patients themselves may miss MCI, if they do not observe carefully. Detection of the disease at the stage of MCI and taking early action may improve the condition or delay the onset of dementia.

Most cases of dementia cannot be completely cured by currently available medicines. However, it is said that the most important for prevention of dementia is to accurately and timely recognition of MCI and adoption of appropriate countermeasures.

This section gives a clear explanation about MCI from various angles.
