Mild cognitive impairment: clinical and imaging profile in a memory clinic setting in India.

Background: Despite the increasing burden of dementia in developing countries, mild cognitive impairment (MCI) continues to be underexplored. MCI has conventionally been identified based on clinical profile, but recently, biomarkers suggestive of Alzheimer's disease pathology have been included in the revised National Institute on Aging and the Alzheimer's Association (NIA-AA) criteria. In this study, we evaluated the profile of MCI in a memory clinic in India and explored the applicability of the revised NIA-AA criteria in a limited resource setting.
