With a Z-score of 0.17 (56.9th percentile), this represents normal volume ; whole brain volume measures 1,036,670 mm³, 6.4% above the reference mean. With a Z-score of 0.80 (78.8th percentile), this represents normal volume ; entorhinal cortex volume measures 3,935 mm³, 7.1% above the reference mean. With a Z-score of 0.44 (66.9th percentile), this represents normal volume ; fusiform gyrus volume measures 21,801 mm³, 28.1% above the reference mean. With a Z-score of 2.56 (99.5th percentile), this represents significant enlargement; middle temporal gyrus volume measures 21,069 mm³, 9.9% above the reference mean.

  "gpt_diagnosis": "**Reasoning:** The hippocampal, whole brain, entorhinal cortex, and middle temporal gyrus volumes are all within normal ranges, with some structures even showing above-average volumes (e.g., fusiform gyrus). Cognitive screening (MMSE 30, MoCA 25) suggests intact global cognition with only mild executive/visuospatial concerns (common in normal aging). No APOE4 risk allele is present.  \n\n**Diagnosis:** **CN (Cognitively Normal)**  \n**Confidence:** **High**",
