With a Z-score of -0.83 (20.2th percentile), this represents normal volume ; whole brain volume measures 922,058 mm³, 10.4% below the reference mean. With a Z-score of -1.36 (8.6th percentile), this represents mild atrophy. ",

  "gpt_diagnosis": "Reasoning: The patient shows mild whole brain atrophy (Z-score -1.36, 8.6th percentile) but normal ventricular volume. The MMSE score of 20 suggests cognitive impairment, but the absence of APOE4 reduces genetic risk. Age-related changes are expected at 89.7 years.  \nDiagnosis: MCI  \nConfidence: Medium",
