With a Z-score of 2.53 (99.4th percentile), this represents significant enlargement; whole brain volume measures 829,026 mm³, 14.9% below the reference mean. With a Z-score of -1.88 (3.0th percentile), this represents moderate atrophy. ",

  "gpt_diagnosis": "Reasoning: The data shows significant ventricular enlargement (Z-score 2.53) and moderate whole brain atrophy (Z-score -1.88), consistent with neurodegenerative changes. Combined with cognitive scores below normal (MMSE 23, MoCA 17) and APOE4 homozygosity, this strongly suggests dementia.  \nDiagnosis: Dementia  \nConfidence: High",
