Biomarker levels: Florbetapir (AV45): 1.02 SUVR (normal ); Amyloid beta: 1303.00 pg/mL (normal ); Total tau: 228.50 pg/mL (normal ); Phosphorylated tau: 18.16 pg/mL (normal ). ",

  "gpt_diagnosis": "Reasoning: The MMSE score of 28 is within the normal range (typically ≥26), but the MoCA score of 22 suggests mild cognitive impairment (MCI) as it falls below the typical cutoff of 26. Biomarkers (Aβ, T-tau, P-tau, AV45) are normal, and there is no APOE4 risk allele, which argues against Alzheimer's pathology.  \nDiagnosis: MCI  \nConfidence: Medium (due to discrepancy between MMSE and MoCA, but normal biomarkers suggest non-Alzheimer's etiology)",
