With a Z-score of -0.02 (49.3th percentile), this represents normal volume ; whole brain volume measures 953,823 mm³, 11.6% below the reference mean. With a Z-score of -1.51 (6.5th percentile), this represents moderate atrophy. ",
  "text_data": "Age is 71.2 years. Gender is Male. Education: 19 years. Handedness: Right. Race: White. Medical history: Head, Eyes, Ears, Nose and Throat; Cardiovascular; Respiratory. MMSE: 26.0. Logical Memory: 2.0. APOEε4 alleles: 0.0. ",

  "gpt_diagnosis": "Reasoning: The whole brain volume shows moderate atrophy (Z-score -1.51, 6.5th percentile), which is concerning for neurodegeneration, but the MMSE score of 26 is only mildly impaired and still within the normal range for age. The absence of APOE4 reduces genetic risk.  \nDiagnosis: Mild Cognitive Impairment (MCI)  \nConfidence: Medium",
