With a Z-score of 1.54 (93.9th percentile), this represents moderate enlargement; whole brain volume measures 864,657 mm³, 19.9% below the reference mean. With a Z-score of -2.58 (0.5th percentile), this represents significant atrophy. ",

  "gpt_diagnosis": "Reasoning: The data shows significant whole brain atrophy (Z-score -2.58, 0.5th percentile) and moderate ventricular enlargement (Z-score 1.54, 93.9th percentile), consistent with advanced neurodegeneration. The cognitive scores (MMSE 14, MoCA 9) are severely impaired, well below typical dementia thresholds.  \nDiagnosis: Dementia  \nConfidence: High",
