With a Z-score of 0.29 (61.2th percentile), this represents normal volume ; whole brain volume measures 1,067,400 mm³, 3.7% above the reference mean. With a Z-score of 0.46 (67.8th percentile), this represents normal volume ; entorhinal cortex volume measures 4,235 mm³, 8.8% above the reference mean. With a Z-score of 0.68 (75.2th percentile), this represents normal volume ; fusiform gyrus volume measures 17,523 mm³, 3.8% below the reference mean. With a Z-score of -0.42 (33.5th percentile), this represents normal volume ; middle temporal gyrus volume measures 21,615 mm³, 5.3% above the reference mean.

  "gpt_diagnosis": "Reasoning: All brain volumes (hippocampus, whole brain, entorhinal cortex, fusiform gyrus, middle temporal gyrus) are within normal ranges (Z-scores between -0.42 and +0.68). Cognitive scores (MMSE 25, MoCA 24) are slightly below typical cutoffs but not strongly indicative of impairment. APOE4 homozygous status increases Alzheimer’s risk but does not confirm pathology.  \nDiagnosis: CN (Cognitively Normal)  \nConfidence: Medium (due to borderline cognitive scores and APOE4 risk, but normal imaging)",
