  "text_data": "Age is 70.2 years. Gender is Female. Education: 12 years. MMSE: 26.0. MoCA: 24.0. Logical Memory: 6.0. APOEε4 alleles: 1.0. Biomarker levels: Florbetapir (AV45): 1.30 SUVR (moderate elevated). ",

  "gpt_diagnosis": "Reasoning: The hippocampal volume is significantly reduced (Z-score -2.35, 0.9th percentile), which is strongly associated with Alzheimer's pathology. The MMSE (26) and MoCA (24) scores are borderline, suggesting mild cognitive deficits, while the presence of APOE4 and elevated AV45 (amyloid PET) further supports Alzheimer's-related changes.  \nDiagnosis: **MCI (likely due to Alzheimer's disease)**  \nConfidence: **High**",
