Biomarker levels: Florbetapir (AV45): 1.01 SUVR (normal ); Amyloid beta: 1633.00 pg/mL (moderate elevated); Total tau: 406.00 pg/mL (significant elevated); Phosphorylated tau: 33.43 pg/mL (moderate elevated).

  "gpt_diagnosis": "Reasoning: The MMSE score of 26 and MoCA score of 23 are borderline, suggesting mild cognitive impairment (MCI). The biomarker profile (moderately elevated Aβ, significantly elevated T-tau, and moderately elevated P-tau) is consistent with Alzheimer's pathology, but the normal AV45 (amyloid PET) complicates the interpretation.  \nDiagnosis: MCI (likely due to Alzheimer's pathology)  \nConfidence: Medium (due to conflicting biomarker results)",
