  "text_data": "Age is 73.0 years. Gender is Male. Medical history: Gastrointestinal; Renal-Genitourinary; Smoking; Malignancy. MMSE: 25. Delayed Recall: 9. Immediate Recall: 12. APOEε4 alleles: 1. ",
  "true_diagnosis": "Diagnosis: CN.",
  "gpt_diagnosis": "Reasoning: The MMSE score of 25 is within the normal range (24-30 typically indicates no cognitive impairment), 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.  \nDiagnosis: CN (Cognitively Normal)  \nConfidence: Medium (due to lack of volumetric data and reliance on MMSE alone, which has limitations in sensitivity).",
