  "img_finding": "Image findings: ventricular volume measures 66,559 mm³, 72.8% above the reference mean. With a Z-score of 1.74 (95.9th percentile), this represents moderate enlargement; hippocampal volume measures 5,943 mm³, 21.4% below the reference mean. With a Z-score of -2.09 (1.9th percentile), this represents significant atrophy; whole brain volume measures 946,054 mm³, 12.4% below the reference mean. With a Z-score of -1.60 (5.4th percentile), this represents moderate atrophy. ",

These structural changes, combined with cognitive test scores below typical cutoffs (MMSE 23, MoCA 16), strongly suggest neurodegenerative pathology.  \nDiagnosis: Dementia  \nConfidence: High",
