  "img_finding": "Image findings: ventricular volume measures 68,169 mm³, 142.9% above the reference mean. With a Z-score of 3.27 (99.9th percentile), this represents profound enlargement; whole brain volume measures 793,154 mm³, 18.6% below the reference mean. With a Z-score of -2.34 (1.0th percentile), this represents significant atrophy. ",
  "text_data": "Age is 77.5 years. Gender is Female. Education: 18 years. Handedness: Right. Race: White. Medical history: Cardiovascular; Musculoskeletal; Major Surgical Procedures. MMSE: 24.0. MoCA: 19.0. Logical Memory: 0.0. APOEε4 alleles: 1.0. ",

  "gpt_diagnosis": "Reasoning: The data shows profound ventricular enlargement and significant whole brain atrophy, both indicative of advanced neurodegeneration. The MMSE (24) and MoCA (19) scores suggest cognitive impairment, with MoCA falling below the typical MCI cutoff (usually <26).  \nDiagnosis: Dementia  \nConfidence: High",
