  "text_data": "Age is 63.7 years. Gender is Male. Education: 15 years. MMSE: 27.0. MoCA: 27.0. Logical Memory: 7.0. APOEε4 alleles: 2.0. Biomarker levels: Florbetapir (AV45): 1.66 SUVR (profound elevated). ",
  "true_diagnosis": "Diagnosis: MCI.",
  "gpt_diagnosis": "Reasoning: The hippocampal volume is within the normal range (50.1th percentile), and cognitive scores (MMSE 27, MoCA 27) are intact, suggesting no significant cognitive impairment. However, the presence of two APOE4 alleles and profoundly elevated AV45 (amyloid PET) indicates a high amyloid burden, which is a strong risk factor for future cognitive decline but does not currently meet criteria for MCI or dementia.  \n\nDiagnosis: CN (Cognitively Normal)  \nConfidence: Medium (due to conflicting biomarkers—normal cognition and structure but high amyloid burden)",
