  "img_finding": "Image findings: hippocampal volume measures 6,895 mm³, 10.3% below the reference mean. With a Z-score of -1.15 (12.4th percentile), this represents mild atrophy. ",
  "text_data": "Age is 62.8 years. Gender is Female. Education: 16 years. MMSE: 27.0. MoCA: 24.0. Logical Memory: 0.0. APOEε4 alleles: 1.0. ",
  "true_diagnosis": "Diagnosis: MCI.",
  "gpt_diagnosis": "**Reasoning:** The hippocampal volume shows mild atrophy (10.3% below mean, Z-score -1.15), but cognitive scores (MMSE 27, MoCA 24) are borderline normal to mildly impaired. APOE4 carrier status increases Alzheimer’s risk, but current cognitive performance does not yet meet dementia criteria.  \n**Diagnosis:** Mild Cognitive Impairment (MCI)  \n**Confidence:** Medium (cognitive scores are near the MCI threshold, and hippocampal atrophy supports early neurodegenerative changes)",
