Biomarker levels: Florbetapir (AV45): 1.37 SUVR (significant elevated); Amyloid beta: 991.80 pg/mL (normal ); Total tau: 713.90 pg/mL (profound elevated); Phosphorylated tau: 86.51 pg/mL (profound elevated).

  "gpt_diagnosis": "Reasoning: The MMSE score of 29 is within the normal range, but the MoCA score of 25 suggests mild cognitive impairment (MCI). The biomarker profile (normal Aβ but elevated T-tau, P-tau, and AV45) indicates significant neurodegeneration and tau pathology, which is atypical for typical Alzheimer's disease but may suggest a tauopathy or mixed pathology.  \nDiagnosis: MCI  \nConfidence: Medium",
