  "img_finding": "Image findings: ventricular volume measures 72,162 mm³, 53.5% above the reference mean. With a Z-score of 1.55 (94.0th percentile), this represents moderate enlargement; whole brain volume measures 774,034 mm³, 24.8% below the reference mean. With a Z-score of -3.25 (0.1th percentile), this represents profound atrophy. ",

  "gpt_diagnosis": "Reasoning: The data shows profound whole brain atrophy (Z-score -3.25) and moderate ventricular enlargement, which are strong indicators of neurodegeneration. Despite relatively preserved cognitive scores (MMSE 26, MoCA 24), the structural changes are severe and disproportionate to age.  \nDiagnosis: Dementia  \nConfidence: High",
