Annotation	Although mild cognitive impairment is associated with increased risk of developing dementia, there has been little work on its incidence and prevalence. The authors used data derived from the Leipzig Longitudinal Study of the Aged (LEILA75+), a community sample of 1,045 dementia-free individuals aged 75+ examined by neuropsychological testing in a 3-wave longitudinal study. Prevalence rates ranged from 3% to 10%, depending on the concept applied. The annual incidence rates applying different case definitions varied from 8 to 77 per 1000 person-years. Rates of conversion to dementia over 2.6 years ranged from 23% to 47%. Mild cognitive impairment is frequent in older people. Prevalence, incidence and predictive validities are highly dependent on the diagnostic criteria applied. (RH).
