With a Z-score of -0.84 (20.1th percentile), this represents normal volume ; hippocampal volume measures 7,334 mm³, 3.1% above the reference mean. With a Z-score of 0.28 (61.1th percentile), this represents normal volume ; whole brain volume measures 908,337 mm³, 6.8% below the reference mean. With a Z-score of -0.86 (19.6th percentile), this represents normal volume ; entorhinal cortex volume measures 3,434 mm³, 6.5% below the reference mean. With a Z-score of -0.40 (34.5th percentile), this represents normal volume ; fusiform gyrus volume measures 15,544 mm³, 8.6% below the reference mean. With a Z-score of -0.79 (21.6th percentile), this represents normal volume ; middle temporal gyrus volume measures 17,787 mm³, 7.2% 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 further reduces Alzheimer's risk.  \n\n**Diagnosis:** CN (Cognitively Normal)  \n**Confidence:** High",
