  "img_finding": "Image findings: ventricular volume measures 76,379 mm³, 62.5% above the reference mean. With a Z-score of 1.81 (96.5th percentile), this represents moderate enlargement; whole brain volume measures 961,254 mm³, 6.6% below the reference mean. With a Z-score of -0.86 (19.4th percentile), this represents normal volume . ",
  "text_data": "Age is 81.0 years. Gender is Male. Education: 20 years. MMSE: 16.0. Logical Memory: 0.0. Laboratory findings: Albumin: 5.10 (profound elevated). APOEε4 alleles: 0.0. ",

  "gpt_diagnosis": "Reasoning: The patient shows significant ventricular enlargement (62.5% above mean, Z-score 1.81) and slightly reduced whole brain volume (6.6% below mean, Z-score -0.86), consistent with atrophy. The MMSE score of 16 indicates severe cognitive impairment, strongly suggestive of dementia.  \nDiagnosis: **Dementia**  \nConfidence: **High**",
