  "text_data": "Age is 64.5 years. Gender is Male. Education: 18 years. MMSE: 29.0. MoCA: 25.0. Logical Memory: 2.0. APOEε4 alleles: 1.0. Biomarker levels: Florbetapir (AV45): 0.99 SUVR (normal ). ",

  "gpt_diagnosis": "**Reasoning:** The hippocampal volume is within the normal range (Z-score 0.47, 67.9th percentile), and cognitive screening scores (MMSE 29, MoCA 25) are largely intact, with no significant amyloid pathology (AV45 normal). The presence of one APOE4 allele increases risk but does not confirm pathology.  \n**Diagnosis:** CN (Cognitively Normal)  \n**Confidence:** High",
