With a Z-score of 1.85 (96.8th percentile), this represents moderate enlargement; whole brain volume measures 979,842 mm³, 9.2% below the reference mean. With a Z-score of -1.20 (11.6th percentile), this represents mild atrophy. ",

  "gpt_diagnosis": "Reasoning: The data shows moderate ventricular enlargement and mild whole brain atrophy, which are consistent with neurodegenerative changes. The MMSE score of 25 is borderline, suggesting possible cognitive impairment, and the presence of one APOE4 allele increases Alzheimer's risk.  \nDiagnosis: MCI (Mild Cognitive Impairment)  \nConfidence: Medium",
