  "text_data": "Age is 79.6 years. Gender is Male. Education: 18 years. MMSE: 29.0. MoCA: 24.0. Logical Memory: 2.0. APOEε4 alleles: 1.0. Biomarker levels: Florbetapir (AV45): 1.43 SUVR (significant elevated); Amyloid beta: 388.90 pg/mL (moderate reduced); Total tau: 247.60 pg/mL (normal ); Phosphorylated tau: 26.41 pg/mL (normal ). ",
  "true_diagnosis": "Diagnosis: MCI.",
  "gpt_diagnosis": "Reasoning: The patient has a high MMSE score (29/30) but a borderline MoCA score (24/30), suggesting possible mild cognitive deficits. Elevated AV45 (amyloid PET) and moderately reduced Aβ (CSF) indicate amyloid pathology, while normal tau levels suggest no significant neurodegeneration at this stage.  \nDiagnosis: MCI (Mild Cognitive Impairment)  \nConfidence: Medium  \n\n(Note: The diagnosis leans toward MCI due to cognitive test discrepancies and amyloid burden, but the high MMSE and normal tau reduce confidence slightly. Progression to dementia is not yet evident.)",
