  "true_diagnosis": "Diagnosis: AD.",
  "gpt_diagnosis": "Reasoning: The MMSE score of 21.0 is below the typical cutoff of 24 for cognitive normality, suggesting cognitive impairment. The presence of two APOE4 alleles increases the risk for Alzheimer's disease, and the age of 82.6 is within a high-risk demographic.  \nDiagnosis: Dementia  \nConfidence: Medium (MMSE is borderline, and additional clinical context or biomarkers would strengthen the diagnosis).",
