With a Z-score of -0.16 (43.7th percentile), this represents normal volume ; hippocampal volume measures 8,209 mm³, 5.1% above the reference mean. With a Z-score of 0.72 (76.3th percentile), this represents normal volume ; whole brain volume measures 1,118,510 mm³, 7.5% above the reference mean. With a Z-score of 0.90 (81.6th percentile), this represents normal volume ; entorhinal cortex volume measures 4,060 mm³, 9.9% above the reference mean. With a Z-score of 0.77 (78.0th percentile), this represents normal volume ; fusiform gyrus volume measures 19,952 mm³, 8.2% above the reference mean. With a Z-score of 0.75 (77.3th percentile), this represents normal volume ; middle temporal gyrus volume measures 19,818 mm³, 3.5% 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 or above the mean. Cognitive scores (MMSE: 29, MoCA: 28) are also within normal limits, indicating no significant cognitive impairment. The presence of one APOE4 allele does not override the absence of structural or functional deficits.  \nDiagnosis: CN (Cognitively Normal)  \nConfidence: High",
