  "img_finding": "Image findings: ventricular volume measures 33,727 mm³, 28.3% below the reference mean. With a Z-score of -0.82 (20.6th percentile), this represents normal volume ; whole brain volume measures 1,036,650 mm³, 0.7% above the reference mean. With a Z-score of 0.10 (53.8th percentile), this represents normal volume . ",
  "text_data": "Age is 83.3 years. Gender is Male. Education: 20 years. MMSE: 29.0. Logical Memory: 0.0. APOEε4 alleles: 0.0. Biomarker levels: Amyloid beta: 673.00 pg/mL (normal ); Total tau: 333.70 pg/mL (mild elevated); Phosphorylated tau: 34.93 pg/mL (moderate elevated). ",

  "gpt_diagnosis": "Reasoning: The brain volumes (ventricular and whole brain) are within normal ranges, and Aβ levels are normal, which argues against Alzheimer's pathology. However, the elevated T-tau and P-tau levels suggest some neurodegenerative activity, though the high MMSE score (29/30) indicates preserved cognitive function.  \nDiagnosis: CN (Cognitively Normal)  \nConfidence: Medium (due to conflicting biomarkers—normal Aβ but elevated tau—despite intact cognition)",
