  "img_finding": "Image findings: ventricular volume measures 89,564 mm³, 132.5% above the reference mean. With a Z-score of 3.17 (99.9th percentile), this represents profound enlargement; whole brain volume measures 878,765 mm³, 18.6% below the reference mean. With a Z-score of -2.41 (0.8th percentile), this represents significant atrophy. ",

  "gpt_diagnosis": "Reasoning: The data shows significant ventricular enlargement (132.5% above mean, Z-score 3.17) and substantial whole brain atrophy (18.6% below mean, Z-score -2.41), which are strong indicators of neurodegeneration. The MMSE score of 24.0 suggests mild cognitive impairment, and the presence of one APOE4 allele increases Alzheimer's risk.  \nDiagnosis: Dementia (likely Alzheimer's disease)  \nConfidence: High",
