  "img_finding": "Image findings: ventricular volume measures 31,724 mm³, 14.2% below the reference mean. With a Z-score of -0.38 (35.1th percentile), this represents normal volume ; whole brain volume measures 717,793 mm³, 22.7% below the reference mean. With a Z-score of -2.72 (0.3th percentile), this represents significant atrophy. ",

The absence of APOE4 and only moderate amyloid burden (AV45) may indicate non-Alzheimer's pathology or mixed etiology.  \nDiagnosis: Dementia  \nConfidence: High",
