  "text_data": "Age is 72.0 years. Gender is Male. Medical history: Musculoskeletal. MMSE: 30. Delayed Recall: 10. Immediate Recall: 13. Laboratory findings: WBC: 3.80 (moderate reduced); Cholesterol (High Performance): 266.79 (moderate elevated); Urea Nitrogen: 22.23 (moderate reduced). APOEε4 alleles: 1. ",
  "true_diagnosis": "Diagnosis: CN.",
  "gpt_diagnosis": "Reasoning: The MMSE score of 30 is within the normal range (typically 24-30), and there is no volumetric data to suggest structural brain changes. The presence of one APOE4 allele increases Alzheimer's risk but is not diagnostic on its own.  \nDiagnosis: CN (Cognitively Normal)  \nConfidence: Medium (due to lack of volumetric data and reliance on MMSE alone, though the score is strongly indicative of normal cognition)",
