With a Z-score of 1.22 (88.8th percentile), this represents mild enlargement; whole brain volume measures 833,624 mm³, 10.2% below the reference mean. With a Z-score of -1.22 (11.1th percentile), this represents mild atrophy. ",

  "gpt_diagnosis": "Reasoning: The data shows mild ventricular enlargement and mild whole brain atrophy, which are consistent with neurodegenerative changes. The MMSE score of 21.0 (below the typical cutoff of 24 for cognitive normality) suggests cognitive impairment, but the absence of APOE4 reduces genetic risk for Alzheimer's.  \nDiagnosis: Dementia  \nConfidence: Medium",
