Biomarker levels: Florbetapir (AV45): 1.13 SUVR (normal ); Amyloid beta: 873.20 pg/mL (normal ); Total tau: 348.20 pg/mL (mild elevated); Phosphorylated tau: 32.24 pg/mL (mild elevated). ",

  "gpt_diagnosis": "Reasoning: The MMSE score of 29 is within the normal range, but the MoCA score of 23 suggests mild cognitive impairment (MCI). Biomarkers show normal Aβ and AV45 (amyloid PET), but mildly elevated T-tau and P-tau, which may indicate early neurodegenerative changes despite no significant amyloid pathology.  \nDiagnosis: MCI  \nConfidence: Medium (due to conflicting MMSE/MoCA scores and biomarker profile)",
