Post-Stroke Cognitive Impairment in Georgia: Diagnostic Utility of Georgian NINDS-CSN Neuropsychological Battery

Background

Post-stroke cognitive impairment (PSCI) affects approximately half of stroke survivors within the first year. Data from low- and middle-income countries, including Georgia, are limited. Although a Georgian-language version of the Montreal Cognitive Assessment (MoCA) has previously been validated as a brief cognitive screening instrument, no validated Georgian-language multidomain neuropsychological battery for vascular or post-stroke cognitive impairment is currently available. This study aimed to validate the Georgian version of the National Institute of Neurological Disorders and Stroke–Canadian Stroke Network (NINDS–CSN) neuropsychological battery by assessing its concurrent validity with the Montreal Cognitive Assessment (MoCA), and to evaluate its clinical utility for estimating PSCI prevalence.
