With a Z-score of 0.57 (71.5th percentile), this represents normal volume ; whole brain volume measures 1,132,490 mm³, 4.9% above the reference mean. With a Z-score of 0.64 (73.8th percentile), this represents normal volume ; entorhinal cortex volume measures 4,111 mm³, 0.3% above the reference mean. With a Z-score of 0.02 (50.7th percentile), this represents normal volume ; fusiform gyrus volume measures 21,237 mm³, 12.7% above the reference mean. With a Z-score of 1.08 (86.1th percentile), this represents mild enlargement; middle temporal gyrus volume measures 23,095 mm³, 8.2% above the reference mean.

  "gpt_diagnosis": "**Reasoning:** All brain volumes (hippocampal, whole brain, entorhinal cortex, fusiform gyrus, and middle temporal gyrus) are within normal ranges or mildly enlarged, with no significant atrophy. Biomarkers (Aβ, T-tau, P-tau, AV45) are normal, and cognitive scores (MMSE 30, MoCA 25) do not indicate significant impairment. APOE4-negative status further reduces Alzheimer's risk.  \n\n**Diagnosis:** CN (Cognitively Normal)  \n**Confidence:** High",
