With a Z-score of 1.82 (96.6th percentile), this represents moderate enlargement; whole brain volume measures 1,002,660 mm³, 7.1% below the reference mean. With a Z-score of -0.92 (17.8th percentile), this represents normal volume . ",

  "gpt_diagnosis": "**Reasoning:** The ventricular volume is moderately enlarged (76.1% above mean, Z-score 1.82), while whole brain volume is normal (7.1% below mean, Z-score -0.92). The MMSE is normal (30/30), but the MoCA (25/30) suggests mild cognitive impairment (MCI), with no APOE4 risk allele.  \n\n**Diagnosis:** **MCI** (Mild Cognitive Impairment)  \n**Confidence:** **Medium** (MoCA indicates possible MCI, but MMSE is normal; structural changes are moderate but not severe enough for dementia)",
