With a Z-score of -0.58 (28.0th percentile), this represents normal volume ; hippocampal volume measures 7,235 mm³, 11.4% above the reference mean. With a Z-score of 0.91 (81.9th percentile), this represents normal volume ; whole brain volume measures 946,572 mm³, 2.0% above the reference mean. With a Z-score of 0.24 (59.4th percentile), this represents normal volume ; entorhinal cortex volume measures 3,309 mm³, 4.4% below the reference mean.

  "gpt_diagnosis": "**Reasoning:** All brain volumes (hippocampal, whole brain, entorhinal cortex, fusiform gyrus, and middle temporal gyrus) are within normal ranges based on Z-scores and percentiles. Cognitive scores (MMSE 25, MoCA 28) are also within normal limits for age, and biomarkers (T-tau, P-tau, AV45) are normal. No significant atrophy or pathological markers are present.  \n\n**Diagnosis:** CN (Cognitively Normal)  \n**Confidence:** High",
