With a Z-score of 0.80 (78.9th percentile), this represents normal volume ; whole brain volume measures 817,860 mm³, 11.9% below the reference mean. With a Z-score of -1.43 (7.7th percentile), this represents mild atrophy. ",

  "gpt_diagnosis": "Reasoning: The patient shows mild whole brain atrophy (Z-score -1.43) but normal ventricular volume. The MMSE score of 22 suggests cognitive impairment, but the absence of APOE4 reduces genetic risk. Age is a significant factor for neurodegeneration.  \nDiagnosis: MCI  \nConfidence: Medium",
