Logical Memory: 1.0. APOEε4 alleles: 2.0. Biomarker levels: Amyloid beta: 212.30 pg/mL (significant reduced); Total tau: 270.60 pg/mL (normal ); Phosphorylated tau: 27.29 pg/mL (normal ). ",
  "true_diagnosis": "Diagnosis: AD.",
  "gpt_diagnosis": "Reasoning: The patient shows significant Aβ reduction (indicative of amyloid pathology) and an MMSE score of 24, which is borderline for cognitive impairment. However, T-tau and P-tau are normal, suggesting no significant neurodegeneration at this stage.  \nDiagnosis: **MCI** (Mild Cognitive Impairment, likely due to Alzheimer's pathology)  \nConfidence: **Medium** (MMSE is borderline, and tau markers are normal, but amyloid burden is significant)",
