MMSE: 27.0. MoCA: 19.0. Logical Memory: 10.0. APOEε4 alleles: 0.0. Biomarker levels: Florbetapir (AV45): 1.37 SUVR (significant elevated); Amyloid beta: 884.00 pg/mL (normal ); Total tau: 297.40 pg/mL (normal ); Phosphorylated tau: 26.82 pg/mL (normal ). ",

  "gpt_diagnosis": "Reasoning: The MMSE score of 27 is within the normal range, but the MoCA score of 19 suggests mild cognitive impairment (MCI). The discrepancy between MMSE and MoCA, along with elevated AV45 (amyloid PET), indicates early amyloid deposition despite normal CSF biomarkers (Aβ, T-tau, P-tau).  \nDiagnosis: MCI  \nConfidence: Medium  \n\n(Note: The confidence is medium due to the conflicting MMSE/MoCA scores and the need for further clinical correlation. The elevated AV45 suggests amyloid pathology, but normal CSF biomarkers introduce some uncertainty.)",
