With a Z-score of 0.06 (52.2th percentile), this represents normal volume ; whole brain volume measures 1,162,050 mm³, 7.7% above the reference mean. With a Z-score of 0.99 (84.0th percentile), this represents normal volume ; entorhinal cortex volume measures 4,197 mm³, 2.4% above the reference mean. With a Z-score of 0.16 (56.3th percentile), this represents normal volume ; fusiform gyrus volume measures 18,904 mm³, 0.3% above the reference mean. With a Z-score of 0.03 (51.2th percentile), this represents normal volume ; middle temporal gyrus volume measures 22,505 mm³, 5.5% above the reference mean.

  "gpt_diagnosis": "Reasoning: The brain volumes (hippocampus, entorhinal cortex, fusiform gyrus, and middle temporal gyrus) are all within normal ranges, with Z-scores close to or slightly above the mean. The MMSE score of 28 is normal, but the MoCA score of 21 suggests mild cognitive impairment (MCI). The absence of APOE4 reduces genetic risk for Alzheimer's.  \nDiagnosis: **MCI**  \nConfidence: **Medium** (due to the discrepancy between MMSE and MoCA, but normal imaging)",
