With a Z-score of 0.74 (77.1th percentile), this represents normal volume ; whole brain volume measures 840,447 mm³, 18.3% below the reference mean. With a Z-score of -2.40 (0.8th percentile), this represents significant atrophy. ",

  "gpt_diagnosis": "Reasoning: The patient shows significant whole brain atrophy (Z-score -2.40, 0.8th percentile) but normal ventricular volume. The MMSE score of 26 is borderline, but the absence of APOE4 reduces genetic risk. Age-related atrophy is likely, but the degree of atrophy is concerning.  \nDiagnosis: MCI  \nConfidence: Medium",
