Biomarker levels: Florbetapir (AV45): 1.04 SUVR (normal ); Amyloid beta: 1558.00 pg/mL (mild elevated); Total tau: 194.50 pg/mL (normal ); Phosphorylated tau: 16.58 pg/mL (normal ). ",

  "gpt_diagnosis": "Reasoning: The MMSE score of 29 is within the normal range, and the MoCA score of 25 is slightly below the typical cutoff of 26, suggesting possible mild cognitive impairment. Biomarkers show mild Aβ elevation but normal tau and AV45, which may indicate early amyloid pathology without significant neurodegeneration.  \nDiagnosis: MCI  \nConfidence: Medium",
