With a Z-score of 0.36 (64.0th percentile), this represents normal volume ; hippocampal volume measures 7,751 mm³, 2.5% above the reference mean. With a Z-score of 0.25 (59.8th percentile), this represents normal volume ; whole brain volume measures 1,087,560 mm³, 0.8% above the reference mean. With a Z-score of 0.10 (53.9th percentile), this represents normal volume ; entorhinal cortex volume measures 4,412 mm³, 7.6% above the reference mean.

  "gpt_diagnosis": "**Reasoning:** All brain volumes (hippocampus, entorhinal cortex, fusiform gyrus, middle temporal gyrus, etc.) are within normal ranges, with Z-scores close to or slightly above the mean. Biomarkers (Aβ, T-tau, P-tau) are normal, and cognitive performance (MMSE 29/30) is intact. No significant atrophy or pathological markers are present.  \n**Diagnosis:** CN (Cognitively Normal)  \n**Confidence:** High",
