Logical Memory: 6.0. APOEε4 alleles: 2.0. Biomarker levels: Florbetapir (AV45): 1.96 SUVR (profound elevated); Amyloid beta: 797.70 pg/mL (normal ); Total tau: 576.70 pg/mL (profound elevated); Phosphorylated tau: 61.67 pg/mL (profound elevated).

  "gpt_diagnosis": "Reasoning: The patient shows significant cognitive impairment (MMSE 22, MoCA 19) with profound elevations in T-tau, P-tau, and AV45 (indicating amyloid burden), despite normal Aβ levels. This biomarker profile is consistent with Alzheimer's pathology, particularly given the presence of two APOE4 alleles, which increases risk.  \n\nDiagnosis: **Dementia (likely Alzheimer’s disease)**  \nConfidence: **High**",
