With a Z-score of 0.85 (80.1th percentile), this represents normal volume ; whole brain volume measures 889,345 mm³, 13.6% below the reference mean. With a Z-score of -1.78 (3.8th percentile), this represents moderate atrophy. ",

  "gpt_diagnosis": "Reasoning: The patient shows moderate whole brain atrophy (Z-score -1.78, 3.8th percentile) but normal ventricular volume. The MMSE score of 26 is borderline, and the presence of two APOE4 alleles increases Alzheimer's risk. At age 88, some atrophy is expected, but the degree here is concerning.  \nDiagnosis: MCI (Mild Cognitive Impairment)  \nConfidence: Medium",
