  "text_data": "Age is 71.3 years. Gender is Male. Education: 14 years. MMSE: 29.0. MoCA: 26.0. Logical Memory: 10.0. APOEε4 alleles: 0.0. Biomarker levels: Florbetapir (AV45): 1.26 SUVR (mild elevated). ",

  "gpt_diagnosis": "Reasoning: The hippocampal volume is significantly enlarged (36.6% above mean, Z-score 3.57), which is atypical for Alzheimer's disease (AD) and suggests a non-degenerative process. Cognitive scores (MMSE 29, MoCA 26) are within normal limits, and the absence of APOE4 and only mild AV45 (amyloid) elevation further reduce the likelihood of AD.  \nDiagnosis: CN (Cognitively Normal)  \nConfidence: High",
