The incidence of MCI differs by subtype and is higher in men: the Mayo Clinic Study of Aging.

ABSTRACT:

Objective

Although incidence rates for mild cognitive impairment (MCI) have been reported, few studies were specifically designed to measure the incidence of MCI and its subtypes using published criteria.
