With a Z-score of 0.10 (53.9th percentile), this represents normal volume ; hippocampal volume measures 7,607 mm³, 0.6% above the reference mean. With a Z-score of 0.06 (52.5th percentile), this represents normal volume ; whole brain volume measures 1,121,530 mm³, 3.9% above the reference mean. With a Z-score of 0.51 (69.4th percentile), this represents normal volume ; entorhinal cortex volume measures 4,092 mm³, 0.2% below the reference mean. With a Z-score of -0.01 (49.4th percentile), this represents normal volume ; fusiform gyrus volume measures 18,931 mm³, 0.5% above the reference mean. With a Z-score of 0.04 (51.7th percentile), this represents normal volume ; middle temporal gyrus volume measures 21,019 mm³, 1.5% below the reference mean.

  "gpt_diagnosis": "**Reasoning:** All brain volume measures (ventricular, hippocampal, whole brain, entorhinal cortex, fusiform gyrus, and middle temporal gyrus) are within normal ranges, with Z-scores close to zero and percentiles near 50%. Cognitive scores (MMSE 28, MoCA 25) are also within normal limits for age, with no significant impairment. The presence of one APOE4 allele increases Alzheimer's risk but does not confirm pathology.  \n\n**Diagnosis:** CN (Cognitively Normal)  \n**Confidence:** High",
