  "text_data": "Age is 87.5 years. Gender is Female. Education: 13 years. MMSE: 25.0. MoCA: 23.0. Logical Memory: 2.0. APOEε4 alleles: 0.0. Biomarker levels: Florbetapir (AV45): 1.18 SUVR (normal ). ",
  "true_diagnosis": "Diagnosis: AD.",
  "gpt_diagnosis": "Reasoning: The patient has normal brain volumes and a normal AV45 scan (indicating no significant amyloid deposition). MMSE and MoCA scores are within the normal range for age, though slightly lower than optimal, which could reflect normal aging or very mild cognitive changes. The absence of APOE4 further reduces Alzheimer's risk.  \n\nDiagnosis: CN (Cognitively Normal)  \nConfidence: Medium (scores are borderline, but imaging and genetics support normal cognition)",
