With a Z-score of -1.15 (12.6th percentile), this represents mild atrophy; whole brain volume measures 967,549 mm³, 6.0% below the reference mean. With a Z-score of -0.78 (21.6th percentile), this represents normal volume . ",
  "text_data": "Age is 88.7 years. Gender is Male. Education: 16 years. MMSE: 22.0. Logical Memory: 0.0. APOEε4 alleles: 0.0. Biomarker levels: Amyloid beta: 571.60 pg/mL (mild reduced); Total tau: 211.10 pg/mL (normal ); Phosphorylated tau: 19.36 pg/mL (normal ). ",

  "gpt_diagnosis": "Reasoning: The patient shows mild ventricular atrophy and normal whole brain volume, which is common in aging. The MMSE score of 22 suggests mild cognitive impairment, supported by mildly reduced Aβ but normal tau levels.  \nDiagnosis: MCI  \nConfidence: Medium",
