  "img_finding": "Image findings: ventricular volume measures 19,779 mm³, 11.5% below the reference mean. With a Z-score of -0.29 (38.7th percentile), this represents normal volume ; hippocampal volume measures 5,580 mm³, 27.4% below the reference mean. With a Z-score of -3.07 (0.1th percentile), this represents profound atrophy; whole brain volume measures 999,777 mm³, 2.9% below the reference mean. With a Z-score of -0.36 (36.1th percentile), this represents normal volume ; entorhinal cortex volume measures 2,816 mm³, 27.7% below the reference mean. With a Z-score of -2.14 (1.6th percentile), this represents significant atrophy; fusiform gyrus volume measures 13,542 mm³, 25.6% below the reference mean. With a Z-score of -2.89 (0.2th percentile), this represents significant atrophy; middle temporal gyrus volume measures 14,760 mm³, 28.1% below the reference mean. With a Z-score of -2.49 (0.6th percentile), this represents significant atrophy. ",

  "gpt_diagnosis": "**Reasoning:** The data shows profound atrophy in the hippocampus and significant atrophy in the entorhinal cortex, fusiform gyrus, and middle temporal gyrus—key regions affected in Alzheimer's disease. The MMSE score of 23 indicates cognitive impairment, and the presence of two APOE4 alleles further increases Alzheimer's risk.  \n\n**Diagnosis:** **Dementia (likely Alzheimer’s disease)**  \n**Confidence:** **High**",
