With a Z-score of 0.21 (58.2th percentile), this represents normal volume ; hippocampal volume measures 7,886 mm³, 1.8% below the reference mean. With a Z-score of -0.18 (43.0th percentile), this represents normal volume ; whole brain volume measures 1,226,390 mm³, 8.1% above the reference mean. With a Z-score of 1.15 (87.4th percentile), this represents mild enlargement; entorhinal cortex volume measures 4,145 mm³, 2.8% below the reference mean. With a Z-score of -0.19 (42.4th percentile), this represents normal volume ; fusiform gyrus volume measures 19,905 mm³, 0.0% below the reference mean. With a Z-score of -0.00 (49.9th percentile), this represents normal volume ; middle temporal gyrus volume measures 25,020 mm³, 11.6% above the reference mean.

  "gpt_diagnosis": "**Reasoning:** All brain volumes (hippocampal, entorhinal cortex, fusiform gyrus, etc.) are within normal ranges or mildly enlarged, with no significant atrophy. Cognitive scores (MMSE 28, MoCA 26) are within normal limits, and the absence of APOE4 further reduces Alzheimer's risk.  \n\n**Diagnosis:** CN (Cognitively Normal)  \n**Confidence:** High",
