With a Z-score of -0.73 (23.3th percentile), this represents normal volume ; hippocampal volume measures 8,415 mm³, 4.8% above the reference mean. With a Z-score of 0.48 (68.5th percentile), this represents normal volume ; whole brain volume measures 1,161,970 mm³, 2.4% above the reference mean. With a Z-score of 0.34 (63.4th percentile), this represents normal volume ; entorhinal cortex volume measures 4,350 mm³, 2.0% above the reference mean. With a Z-score of 0.14 (55.6th percentile), this represents normal volume ; fusiform gyrus volume measures 19,741 mm³, 0.8% below the reference mean. With a Z-score of -0.07 (47.2th percentile), this represents normal volume ; middle temporal gyrus volume measures 21,571 mm³, 3.8% below the reference mean.

  "gpt_diagnosis": "**Reasoning:** All brain volume measures (ventricular, hippocampal, whole brain, entorhinal cortex, fusiform gyrus, and middle temporal gyrus) fall within normal ranges based on Z-scores and percentiles. The MMSE score of 30/30 indicates no cognitive impairment, and the absence of APOE4 alleles reduces genetic risk for Alzheimer's.  \n\n**Diagnosis:** CN (Cognitively Normal)  \n**Confidence:** High",
