With a Z-score of 0.29 (61.4th percentile), this represents normal volume ; hippocampal volume measures 7,573 mm³, 0.2% above the reference mean. With a Z-score of 0.02 (50.7th percentile), this represents normal volume ; whole brain volume measures 1,137,720 mm³, 5.4% above the reference mean. With a Z-score of 0.70 (75.8th percentile), this represents normal volume ; entorhinal cortex volume measures 4,247 mm³, 3.6% above the reference mean. With a Z-score of 0.24 (59.6th percentile), this represents normal volume ; fusiform gyrus volume measures 20,809 mm³, 10.5% above the reference mean. With a Z-score of 0.89 (81.4th percentile), this represents normal volume ; middle temporal gyrus volume measures 21,530 mm³, 0.9% above the reference mean.

  "gpt_diagnosis": "Reasoning: All brain volume measures (ventricular, hippocampal, whole brain, entorhinal cortex, fusiform gyrus, middle temporal gyrus) are within normal ranges, with Z-scores close to or slightly above the mean. The MMSE score of 30 is optimal, and both T-tau and P-tau levels are normal, with no APOE4 alleles present.  \nDiagnosis: CN (Cognitively Normal)  \nConfidence: High",
