  "img_finding": "Image findings: ventricular volume measures 38,329 mm³, 0.5% below the reference mean. With a Z-score of -0.01 (49.5th percentile), this represents normal volume ; hippocampal volume measures 5,211 mm³, 31.1% below the reference mean. With a Z-score of -3.03 (0.1th percentile), this represents profound atrophy; whole brain volume measures 812,600 mm³, 24.7% below the reference mean. With a Z-score of -3.21 (0.1th percentile), this represents profound atrophy. ",
  "text_data": "Age is 74.9 years. Gender is Male. Education: 12 years. MMSE: 23.0. MoCA: 14.0. Laboratory findings: Monocytes: 0.63 (significant elevated); Alkaline Phosphatase: 124.00 (significant elevated); Serum Uric Acid: 8.60 (significant elevated). APOEε4 alleles: 2.0. ",

  "gpt_diagnosis": "Reasoning: The data shows profound atrophy in both hippocampal and whole brain volumes (Z-scores of -3.03 and -3.21, respectively), which are strongly associated with Alzheimer's pathology. The cognitive scores (MMSE 23, MoCA 14) indicate significant impairment, and the presence of two APOE4 alleles further increases Alzheimer's risk.  \nDiagnosis: Dementia (likely Alzheimer's disease)  \nConfidence: High",
