  "img_finding": "Image findings: ventricular volume measures 33,242 mm³, 13.7% below the reference mean. With a Z-score of -0.33 (37.1th percentile), this represents normal volume ; hippocampal volume measures 4,745 mm³, 37.2% below the reference mean. With a Z-score of -3.63 (0.0th percentile), this represents profound atrophy; whole brain volume measures 945,147 mm³, 12.4% below the reference mean. With a Z-score of -1.61 (5.3th percentile), this represents moderate atrophy; entorhinal cortex volume measures 1,697 mm³, 58.6% below the reference mean. With a Z-score of -3.98 (0.0th percentile), this represents profound atrophy; fusiform gyrus volume measures 16,265 mm³, 13.7% below the reference mean. With a Z-score of -1.16 (12.2th percentile), this represents mild atrophy; middle temporal gyrus volume measures 16,853 mm³, 21.0% below the reference mean. With a Z-score of -1.89 (2.9th percentile), this represents moderate atrophy. ",

  "gpt_diagnosis": "Reasoning: The data shows profound atrophy in the hippocampus and entorhinal cortex, which are key regions affected in Alzheimer's disease. The MMSE and MoCA scores (16 and 8, respectively) indicate significant cognitive impairment, consistent with dementia. The presence of two APOE4 alleles further supports a high risk for Alzheimer's.  \nDiagnosis: Dementia (likely Alzheimer's disease)  \nConfidence: High",
