Nimhans Neuropsychological Battery Ppt May 2026

The NIMHANS Neuropsychological Battery (NNB) is a comprehensive set of tests developed in 2004 by the National Institute of Mental Health and Neurosciences (NIMHANS), Bangalore. It is specifically designed to be culturally and linguistically sensitive for the Indian population, providing normative data for adults aged 16–65. Key Cognitive Domains Tested

  1. Ecological Validity: Stimuli are familiar (e.g., "auto-rickshaw," "chapati"). A patient who fails to name "snow" in a Western test might be perfectly intact; failing to name "mango" is pathognomonic.
  2. Literacy-Fairness: The CTT and certain visuospatial tasks do not require reading, making them suitable for low-literacy individuals.
  3. Linguistic Diversity: Instructions can be given in the patient's mother tongue without loss of psychometric properties.
  4. Cost-Effectiveness: Most subtests use simple materials (paper, pencils, colored blocks) – no expensive computer or licensing fees.
  5. Local Norms: Interpretations are not confounded by cultural differences in test-taking attitudes (e.g., speed vs. accuracy emphasis).

4. Key Subtests (Commonly Included)

  1. Digit Forward & Backward – Attention and working memory.
  2. Rey’s Auditory Verbal Learning Test (RAVLT) – Verbal learning and memory.
  3. Rey-Osterrieth Complex Figure Test (ROCFT) – Visuospatial construction and visual memory.
  4. Trail Making Test (TMT) A & B – Psychomotor speed and cognitive flexibility.
  5. Verbal Fluency (Animals / ‘P’ words) – Executive function and semantic access.
  6. Stroop Test – Inhibitory control and selective attention.
  7. NIMHANS Aphasia Screening Test – Language deficits.
  8. Motor Speed Tasks – Finger tapping, hand dynamometer (optional).

B. Diagnostic Battery (Specific Domains)

If a deficit is suspected, specific tests are administered to pinpoint the location and severity of brain damage. recognition | | Language | Naming

| Domain | Functions Assessed | |--------|--------------------| | Attention & Concentration | Digit span, cancellation tasks | | Executive Functions | Verbal fluency (phonemic & semantic), Trail Making Test (Part A & B), Stroop Test | | Memory | Verbal and visual recall (immediate & delayed), recognition | | Language | Naming, comprehension, repetition, aphasia screening | | Visuospatial & Constructional Ability | Clock drawing, complex figure copy, block design | | Motor Speed & Manual Dexterity | Finger tapping, grooved pegboard |

Specialized Screening: Detecting early signs of cognitive decline in conditions like Parkinson’s Disease (PD-MCI) with high sensitivity and specificity. Why It Matters
