  "img_finding": "Image findings: ventricular volume measures 79,156 mm³, 105.5% above the reference mean. With a Z-score of 2.53 (99.4th percentile), this represents significant enlargement. ",
  "text_data": "Age is 75.9 years. Gender is Male. Education: 18 years. MMSE: 23.0. MoCA: 23.0. Logical Memory: 0.0. APOEε4 alleles: 1.0. ",
  "true_diagnosis": "Diagnosis: AD.",
  "gpt_diagnosis": "**Reasoning:** The significant ventricular enlargement (Z-score 2.53, 99.4th percentile) suggests substantial brain atrophy, which is consistent with neurodegenerative processes. The MMSE and MoCA scores (both 23) are borderline, indicating possible cognitive impairment, but not severe enough for a definitive dementia diagnosis.  \n\n**Diagnosis:** **Mild Cognitive Impairment (MCI)**  \n**Confidence:** **Medium** (Cognitive scores are borderline, and ventricular enlargement strongly suggests neurodegeneration, but clinical correlation is needed to rule out other causes.)",
