  "img_finding": "Image findings: ventricular volume measures 50,169 mm³, 35.7% above the reference mean. With a Z-score of 0.96 (83.3th percentile), this represents normal volume ; whole brain volume measures 805,478 mm³, 13.2% below the reference mean. With a Z-score of -1.59 (5.6th percentile), this represents moderate atrophy. ",

  "gpt_diagnosis": "Reasoning: The patient shows moderate whole brain atrophy (Z-score -1.59, 5.6th percentile) with normal ventricular volume. Combined with low MMSE (16) and MoCA (15) scores, this suggests significant cognitive impairment. The absence of APOE4 does not rule out dementia given the clinical and imaging findings.  \nDiagnosis: Dementia  \nConfidence: High",
