Medical history: Head, Eyes, Ears, Nose and Throat; Dermatologic-Connective Tissue; Musculoskeletal; Renal-Genitourinary; Malignancy; Major Surgical Procedures. MMSE: 30.0. Logical Memory: 15.0. APOEε4 alleles: 1.0. Biomarker levels: Amyloid beta: 935.30 pg/mL (normal ); Total tau: 336.90 pg/mL (mild elevated); Phosphorylated tau: 34.21 pg/mL (moderate elevated). ",
  "true_diagnosis": "Diagnosis: CN.",
  "gpt_diagnosis": "Reasoning: The patient has a normal MMSE score (30/30) and normal Aβ levels, but shows mild elevation in T-tau and moderate elevation in P-tau, which may indicate early neurodegenerative changes despite preserved cognition. The presence of one APOE4 allele increases Alzheimer's risk but does not confirm pathology.  \nDiagnosis: CN (Cognitively Normal)  \nConfidence: Medium (Biomarkers suggest possible preclinical AD, but cognition remains intact.)",
