With a Z-score of -0.53 (29.9th percentile), this represents normal volume ; whole brain volume measures 1,096,880 mm³, 1.6% above the reference mean. With a Z-score of 0.21 (58.3th percentile), this represents normal volume ; entorhinal cortex volume measures 4,400 mm³, 7.3% above the reference mean. With a Z-score of 0.50 (69.0th percentile), this represents normal volume ; fusiform gyrus volume measures 19,676 mm³, 4.4% above the reference mean.

  "gpt_diagnosis": "Reasoning: All brain volumes (ventricular, hippocampal, whole brain, entorhinal cortex, fusiform gyrus, and middle temporal gyrus) are within normal ranges based on Z-scores and percentiles. Cognitive scores (MMSE 29, MoCA 26) are also within normal limits for age, and biomarkers (T-tau, P-tau, AV45) are normal. The presence of one APOE4 allele increases Alzheimer's risk but does not confirm pathology.  \nDiagnosis: CN (Cognitively Normal)  \nConfidence: High",
