  "text_data": "Age is 90.8 years. Gender is Female. Education: 13 years. MMSE: 23.0. MoCA: 22.0. Logical Memory: 5.0. APOEε4 alleles: 0.0. ",

  "gpt_diagnosis": "Reasoning: The hippocampal volume shows profound atrophy (Z-score -7.19, 0.0th percentile), which is strongly indicative of neurodegeneration. Despite relatively preserved cognitive scores (MMSE 23, MoCA 22), the severity of hippocampal atrophy in a 90-year-old female suggests significant underlying pathology.  \nDiagnosis: **Dementia** (likely Alzheimer’s disease given hippocampal atrophy, though APOE4-negative status slightly reduces certainty).  \nConfidence: **High** (due to extreme hippocampal atrophy, though clinical scores are borderline).",
