With a Z-score of -0.83 (20.4th percentile), this represents normal volume ; whole brain volume measures 908,239 mm³, 11.7% below the reference mean. With a Z-score of -1.54 (6.2th percentile), this represents moderate atrophy. ",

  "gpt_diagnosis": "Reasoning: The patient shows moderate whole brain atrophy (Z-score -1.54, 6.2th percentile) but normal ventricular volume. The MMSE score of 24 is borderline, suggesting possible cognitive impairment, but the absence of APOE4 reduces genetic risk.  \nDiagnosis: MCI  \nConfidence: Medium",
