Biomarker levels: Florbetapir (AV45): 1.35 SUVR (significant elevated); Amyloid beta: 461.80 pg/mL (mild reduced); Total tau: 253.50 pg/mL (normal ); Phosphorylated tau: 26.82 pg/mL (normal ). ",

  "gpt_diagnosis": "Reasoning: The MMSE and MoCA scores are within normal ranges (MMSE 30, MoCA 27), suggesting intact cognitive function. However, elevated AV45 (amyloid PET) and mildly reduced Aβ (CSF) indicate amyloid pathology, which is a biomarker for Alzheimer's disease, despite normal tau levels.  \n\nDiagnosis: **CN (Cognitively Normal, but with amyloid pathology - preclinical AD)**  \nConfidence: **Medium** (Cognitive scores are normal, but biomarker evidence suggests early Alzheimer's pathology.)",
