            NIMHANS Neuropsychological Battery is a comprehensive, indigenous assessment tool widely regarded as the "gold standard" for evaluating cognitive functions within the Indian population. It was specifically designed to overcome the limitations of Western tools by grounding its tests in Indian cultural, linguistic, and educational contexts. Psychology Town Core Cognitive Domains & Tests The battery evaluates 15 functions across 7 major domains: Finger Tapping, Digit Symbol Substitution Measures motor and mental processing speed. Colour Trails, Digit Vigilance, Triads Assesses focused, sustained, and divided attention.
