With a Z-score of 0.79 (78.5th percentile), this represents normal volume ; hippocampal volume measures 7,798 mm³, 0.1% below the reference mean. With a Z-score of -0.02 (49.3th percentile), this represents normal volume ; whole brain volume measures 986,424 mm³, 5.2% below the reference mean. With a Z-score of -0.62 (26.6th percentile), this represents normal volume ; entorhinal cortex volume measures 3,948 mm³, 6.8% above the reference mean. With a Z-score of 0.53 (70.4th percentile), this represents normal volume ; fusiform gyrus volume measures 17,124 mm³, 7.1% below the reference mean. With a Z-score of -0.64 (26.0th percentile), this represents normal volume ; middle temporal gyrus volume measures 18,513 mm³, 9.8% below the reference mean.

  "gpt_diagnosis": "**Reasoning:** All brain volumes (hippocampal, whole brain, entorhinal cortex, fusiform gyrus, and middle temporal gyrus) fall within normal ranges based on Z-scores and percentiles. Cognitive scores (MMSE 27, MoCA 26) are within normal limits, and biomarkers (T-tau, P-tau, AV45) are normal.  \n\n**Diagnosis:** CN (Cognitively Normal)  \n**Confidence:** High",
