With a Z-score of -0.54 (29.3th percentile), this represents normal volume ; hippocampal volume measures 7,977 mm³, 2.2% above the reference mean. With a Z-score of 0.30 (61.8th percentile), this represents normal volume ; whole brain volume measures 1,070,510 mm³, 2.9% above the reference mean. With a Z-score of 0.35 (63.5th percentile), this represents normal volume ; entorhinal cortex volume measures 3,888 mm³, 5.2% above the reference mean. With a Z-score of 0.41 (65.8th percentile), this represents normal volume ; fusiform gyrus volume measures 20,223 mm³, 9.7% above the reference mean.

  "gpt_diagnosis": "**Reasoning:** All brain volumes (hippocampus, entorhinal cortex, fusiform gyrus, middle temporal gyrus, and whole brain) are within normal ranges, with Z-scores close to or above the mean. Biomarkers (Aβ, T-tau, P-tau, AV45) are normal, and cognitive scores (MMSE, MoCA) are at ceiling levels. APOE4 carrier status alone does not indicate pathology in the absence of other abnormalities.  \n\n**Diagnosis:** CN (Cognitively Normal)  \n**Confidence:** High",
