With a Z-score of 2.68 (99.6th percentile), this represents significant enlargement; whole brain volume measures 1,067,540 mm³, 1.1% below the reference mean. With a Z-score of -0.14 (44.3th percentile), this represents normal volume . ",

  "gpt_diagnosis": "Reasoning: The significant ventricular enlargement (Z-score 2.68) suggests substantial atrophy, consistent with neurodegenerative changes. The MMSE and MoCA scores of 22 indicate mild cognitive impairment, though not severe enough for dementia. The absence of APOE4 reduces Alzheimer's risk but doesn't rule out other causes.  \nDiagnosis: MCI  \nConfidence: Medium",
