  "text_data": "Age is 84.0 years. Gender is Male. Education: 12 years. MMSE: 24.0. MoCA: 22.0. Logical Memory: 3.0. APOEε4 alleles: 2.0. Biomarker levels: Florbetapir (AV45): 1.60 SUVR (profound elevated). ",

  "gpt_diagnosis": "Reasoning: The hippocampal volume is significantly reduced (25% below mean, Z-score -2.16), which is strongly associated with Alzheimer's pathology. The MMSE (24) and MoCA (22) scores indicate mild cognitive impairment, and the presence of two APOE4 alleles plus elevated AV45 (amyloid PET) strongly supports Alzheimer's pathophysiology.  \nDiagnosis: Dementia (likely Alzheimer’s disease)  \nConfidence: High",
