With a Z-score of -0.18 (43.0th percentile), this represents normal volume ; whole brain volume measures 924,923 mm³, 10.1% below the reference mean. With a Z-score of -1.26 (10.4th percentile), this represents mild atrophy. ",

  "gpt_diagnosis": "Reasoning: The patient shows mild whole brain atrophy (10.1% below reference mean, Z-score -1.26) but normal ventricular volume. The MMSE score of 23 suggests mild cognitive impairment, and the presence of one APOE4 allele increases Alzheimer's risk.  \nDiagnosis: MCI  \nConfidence: Medium",
