  "img_finding": "Image findings: whole brain volume measures 1,010,010 mm³, 6.4% below the reference mean. With a Z-score of -0.83 (20.2th percentile), this represents normal volume . ",
  "text_data": "Age is 79.6 years. Gender is Male. Education: 20 years. MMSE: 19.0. Logical Memory: 1.0. APOEε4 alleles: 0.0. Biomarker levels: Amyloid beta: 759.30 pg/mL (normal ); Total tau: 359.60 pg/mL (moderate elevated); Phosphorylated tau: 36.80 pg/mL (significant elevated). ",
  "true_diagnosis": "Diagnosis: AD.",
  "gpt_diagnosis": "**Reasoning:** The patient shows significant elevation in P-tau and moderate elevation in T-tau, which are biomarkers for Alzheimer's pathology, despite normal Aβ levels. The MMSE score of 19 suggests cognitive impairment, but brain volume is within normal limits for age.  \n**Diagnosis:** **Dementia (likely Alzheimer’s disease)**  \n**Confidence:** **Medium** (due to conflicting biomarkers—normal Aβ but elevated tau—and borderline MMSE, though tau elevation strongly suggests neurodegeneration)",
