With a Z-score of -0.09 (46.3th percentile), this represents normal volume ; entorhinal cortex volume measures 4,063 mm³, 0.9% below the reference mean. With a Z-score of -0.06 (47.5th percentile), this represents normal volume ; fusiform gyrus volume measures 20,826 mm³, 10.6% above the reference mean. With a Z-score of 0.90 (81.6th percentile), this represents normal volume ; middle temporal gyrus volume measures 21,962 mm³, 2.9% above the reference mean.

  "gpt_diagnosis": "Reasoning: The brain volumes (whole brain, entorhinal cortex, fusiform gyrus, middle temporal gyrus) are all within normal ranges, with no significant atrophy. However, the MoCA score of 22 suggests mild cognitive impairment, while the MMSE of 26 is borderline normal. APOE4 carrier status increases Alzheimer’s risk but is not diagnostic alone.  \nDiagnosis: **MCI**  \nConfidence: **Medium** (due to borderline cognitive scores but normal imaging)",
