  "text_data": "Age is 90.8 years. Gender is Female. Education: 13 years. MMSE: 29.0. MoCA: 18.0. Logical Memory: 12.0. APOEε4 alleles: 0.0. Biomarker levels: Florbetapir (AV45): 1.42 SUVR (significant elevated). ",

  "gpt_diagnosis": "Reasoning: The hippocampal volume shows profound atrophy (Z-score -7.66, 0.0th percentile), strongly suggestive of neurodegeneration. Despite a high MMSE (29.0), the MoCA score (18.0) indicates significant cognitive impairment, and elevated AV45 (amyloid PET) supports Alzheimer's pathology.  \nDiagnosis: **Dementia (likely Alzheimer’s disease)**  \nConfidence: **High**",
