With a Z-score of -0.40 (34.3th percentile), this represents normal volume ; hippocampal volume measures 7,851 mm³, 10.4% above the reference mean. With a Z-score of 0.95 (82.9th percentile), this represents normal volume ; whole brain volume measures 1,003,470 mm³, 3.0% above the reference mean. With a Z-score of 0.37 (64.5th percentile), this represents normal volume ; entorhinal cortex volume measures 4,050 mm³, 10.3% above the reference mean. With a Z-score of 0.63 (73.6th percentile), this represents normal volume ; fusiform gyrus volume measures 16,578 mm³, 2.6% below the reference mean. With a Z-score of -0.23 (40.8th percentile), this represents normal volume ; middle temporal gyrus volume measures 18,593 mm³, 3.0% below the reference mean.

  "gpt_diagnosis": "**Reasoning:** All brain volumes (hippocampus, entorhinal cortex, fusiform gyrus, etc.) are within normal ranges based on Z-scores and percentiles. The MMSE score of 30 is normal, but the MoCA score of 22 suggests mild cognitive impairment (MCI). Biomarkers (T-tau, P-tau, AV45) are normal, and there is no APOE4 risk allele.  \n**Diagnosis:** **MCI** (due to MoCA score discrepancy despite normal imaging and biomarkers)  \n**Confidence:** **Medium** (MoCA suggests impairment, but other markers are normal)",
