  "text_data": "Age is 80.9 years. Gender is Male. Education: 16 years. MMSE: 28.0. MoCA: 24.0. Logical Memory: 15.0. APOEε4 alleles: 0.0. Biomarker levels: Florbetapir (AV45): 0.96 SUVR (normal ). ",

  "gpt_diagnosis": "**Reasoning:** The hippocampal volume is above the reference mean, indicating no significant atrophy. Cognitive scores (MMSE 28, MoCA 24) are within normal limits for age, and amyloid PET (AV45) is normal. No genetic risk (APOE4 negative) further supports cognitive stability.  \n\n**Diagnosis:** CN (Cognitively Normal)  \n**Confidence:** High",
