With a Z-score of 0.28 (61.2th percentile), this represents normal volume ; whole brain volume measures 910,224 mm³, 15.7% below the reference mean. With a Z-score of -2.03 (2.1th percentile), this represents significant atrophy. ",

  "gpt_diagnosis": "Reasoning: The patient shows significant whole brain atrophy (Z-score -2.03, 2.1th percentile) but normal ventricular volume. The MMSE score of 25 is borderline, and the absence of APOE4 reduces genetic risk. These findings suggest cognitive impairment but not severe dementia.  \nDiagnosis: MCI  \nConfidence: Medium",
