Population-Based Norms for the Montreal Cognitive Assessment in Arab Adults.

Objective: The Montreal Cognitive Assessment (MoCA) is a brief screening instrument for detecting mild cognitive dysfunction, a precursor to many cognitive disorders, such as dementia, which have increased in prevalence globally. Qatar, a small high-income country, has the largest projected increase in dementia of any country in the Middle East. Yet no population-based norms for cognitive function are available to date.
