With a Z-score of 0.72 (76.3th percentile), this represents normal volume ; whole brain volume measures 1,011,350 mm³, 1.7% below the reference mean. With a Z-score of -0.23 (41.0th percentile), this represents normal volume . ",
  "text_data": "Age is 85.0 years. Gender is Male. Education: 12 years. MMSE: 14.0. Logical Memory: 0.0. APOEε4 alleles: 1.0. Biomarker levels: Amyloid beta: 740.90 pg/mL (normal ); Total tau: 414.50 pg/mL (significant elevated); Phosphorylated tau: 40.55 pg/mL (significant elevated). ",

  "gpt_diagnosis": "Reasoning: The MMSE score of 14 indicates significant cognitive impairment, and the elevated T-tau and P-tau levels suggest neurodegenerative pathology, despite normal Aβ levels. The brain volumes are within normal ranges, but the clinical presentation and biomarker profile are concerning for dementia.  \nDiagnosis: Dementia  \nConfidence: Medium (due to normal Aβ but high tau and low MMSE)",
