  "img_finding": "Image findings: ventricular volume measures 59,171 mm³, 110.8% above the reference mean. With a Z-score of 2.54 (99.4th percentile), this represents significant enlargement; whole brain volume measures 865,154 mm³, 11.2% below the reference mean. With a Z-score of -1.41 (7.9th percentile), this represents mild atrophy. ",
  "text_data": "Age is 77.7 years. Gender is Female. Education: 8 years. Handedness: Right. Race: White. Medical history: Psychiatric; Gastrointestinal; Hematopoietic-Lymphatic; Allergies or Drug Sensitivities; Major Surgical Procedures. MMSE: 10.0. MoCA: 4.0. Logical Memory: 0.0. APOEε4 alleles: 1.0.

  "gpt_diagnosis": "Reasoning: The data shows significant ventricular enlargement (Z-score 2.54) and mild whole brain atrophy (Z-score -1.41), consistent with advanced neurodegeneration. The very low MMSE (10) and MoCA (4) scores, along with elevated AV45 (amyloid burden), strongly suggest severe cognitive impairment.  \nDiagnosis: Dementia  \nConfidence: High",
