Medical history: Neurologic; Head, Eyes, Ears, Nose and Throat; Cardiovascular; Gastrointestinal; Smoking; Major Surgical Procedures. MMSE: 26.0. Logical Memory: 4.0. APOEε4 alleles: 0.0. Biomarker levels: Total tau: 259.70 pg/mL (normal ); Phosphorylated tau: 24.96 pg/mL (normal ). ",
  "true_diagnosis": "Diagnosis: MCI.",
  "gpt_diagnosis": "Reasoning: The MMSE score of 26 is within the normal range (typically 24-30), and both T-tau and P-tau levels are normal, suggesting no significant neurodegenerative pathology. The absence of APOE4 alleles further reduces Alzheimer's risk.  \nDiagnosis: CN (Cognitively Normal)  \nConfidence: Medium (MMSE is borderline, but biomarkers and genetics support normal cognition)",
