Mild cognitive impairment (MCI)

DELeichte kognitive Beeinträchtigung (MCI)

Mild cognitive impairment (MCI) sits between normal aging and dementia. By Petersen's criteria, it means tests show a real cognitive decline, but you still handle daily life on your own, and you do not meet the bar for dementia. In clinic-based groups, roughly 10 to 15% of people with MCI progress to dementia each year; community samples show lower rates. In longevity medicine, it is a key window to act. Lifestyle changes, treating vascular risk, better sleep, and correcting hearing can stabilize symptoms, or even partly reverse them.
