  "img_finding": "Image findings: ventricular volume measures 73,128 mm³, 160.5% above the reference mean. With a Z-score of 3.68 (100.0th percentile), this represents profound enlargement; whole brain volume measures 881,741 mm³, 9.5% below the reference mean. With a Z-score of -1.20 (11.5th percentile), this represents mild atrophy. ",
  "text_data": "Age is 78.3 years. Gender is Female. Education: 16 years. MMSE: 24.0. Logical Memory: 0.0. APOEε4 alleles: 2.0. Biomarker levels: Amyloid beta: 446.40 pg/mL (moderate reduced); Total tau: 380.40 pg/mL (moderate elevated); Phosphorylated tau: 38.91 pg/mL (significant elevated). ",

  "gpt_diagnosis": "**Reasoning:** The data shows profound ventricular enlargement (Z-score 3.68) and mild whole-brain atrophy (Z-score -1.20), along with significant biomarker abnormalities (elevated tau and reduced Aβ). The MMSE score of 24 suggests cognitive impairment, and the presence of two APOE4 alleles increases Alzheimer's risk.  \n**Diagnosis:** Dementia (likely Alzheimer’s disease)  \n**Confidence:** High",
