With a Z-score of 0.80 (78.9th percentile), this represents normal volume ; whole brain volume measures 1,051,260 mm³, 2.1% above the reference mean. With a Z-score of 0.27 (60.5th percentile), this represents normal volume ; entorhinal cortex volume measures 3,961 mm³, 1.7% above the reference mean. With a Z-score of 0.14 (55.4th percentile), this represents normal volume ; fusiform gyrus volume measures 17,657 mm³, 3.0% below the reference mean. With a Z-score of -0.34 (36.6th percentile), this represents normal volume ; middle temporal gyrus volume measures 20,476 mm³, 0.2% below the reference mean.

  "gpt_diagnosis": "**Reasoning:** All measured brain volumes (hippocampus, whole brain, entorhinal cortex, fusiform gyrus, middle temporal gyrus) are within normal ranges, with no significant atrophy. Cognitive screening (MMSE 29, MoCA 24) shows no significant impairment, and the absence of APOE4 further reduces Alzheimer's risk.  \n\n**Diagnosis:** CN (Cognitively Normal)  \n**Confidence:** High",
