With a Z-score of 0.61 (73.0th percentile), this represents normal volume ; whole brain volume measures 849,218 mm³, 17.5% below the reference mean. With a Z-score of -2.29 (1.1th percentile), this represents significant atrophy. ",

  "gpt_diagnosis": "Reasoning: The patient shows significant whole brain atrophy (Z-score -2.29, 1.1th percentile) but normal ventricular volume. The MMSE score of 25 is borderline, and the absence of APOE4 reduces genetic risk. Age is a significant factor for neurodegeneration.  \nDiagnosis: MCI (Mild Cognitive Impairment)  \nConfidence: Medium",
