  "text_data": "Age is 71.7 years. Gender is Male. Education: 20 years. MMSE: 29.0. MoCA: 25.0. Logical Memory: 12.0. APOEε4 alleles: 0.0. Biomarker levels: Florbetapir (AV45): 0.98 SUVR (normal ). ",

  "gpt_diagnosis": "**Reasoning:** The hippocampal volume is significantly above the reference mean (17.5% higher, Z-score 1.71), which is unusual for Alzheimer's disease (AD) as hippocampal atrophy is a hallmark of AD. Cognitive scores (MMSE 29, MoCA 25) are within normal limits, and amyloid PET (AV45) is negative, further reducing the likelihood of AD.  \n**Diagnosis:** CN (Cognitively Normal)  \n**Confidence:** High",
