Medical history: Psychiatric; Head, Eyes, Ears, Nose and Throat; Cardiovascular; Musculoskeletal; Endocrine-Metabolic; Malignancy; Major Surgical Procedures. MMSE: 18.0. MoCA: 11.0. Logical Memory: 0.0. APOEε4 alleles: 2.0. Biomarker levels: Florbetapir (AV45): 1.41 SUVR (significant elevated); Amyloid beta: 314.00 pg/mL (moderate reduced); Total tau: 275.70 pg/mL (normal ); Phosphorylated tau: 24.01 pg/mL (normal ). ",
  "true_diagnosis": "Diagnosis: AD.",
  "gpt_diagnosis": "Reasoning: The patient shows significant cognitive impairment (MMSE 18, MoCA 11), elevated amyloid burden (AV45), and moderately reduced Aβ, consistent with Alzheimer's pathology. The absence of elevated tau biomarkers suggests less neurodegeneration but does not rule out AD.  \nDiagnosis: Dementia (likely Alzheimer's disease)  \nConfidence: Medium (high amyloid burden supports AD, but tau levels are normal, which is atypical for advanced AD)",
