With a Z-score of 0.98 (83.8th percentile), this represents normal volume ; whole brain volume measures 1,006,610 mm³, 2.2% below the reference mean. With a Z-score of -0.27 (39.3th percentile), this represents normal volume ; entorhinal cortex volume measures 3,596 mm³, 7.6% below the reference mean. With a Z-score of -0.59 (27.7th percentile), this represents normal volume ; fusiform gyrus volume measures 18,275 mm³, 0.4% above the reference mean. With a Z-score of 0.04 (51.6th percentile), this represents normal volume ; middle temporal gyrus volume measures 18,976 mm³, 7.5% below the reference mean.

  "gpt_diagnosis": "**Reasoning:** The brain volume measurements are within normal ranges (Z-scores between -0.67 and 0.98), with no significant atrophy in key regions like the entorhinal cortex or middle temporal gyrus. Cognitive scores (MMSE 29, MoCA 28) are intact, and biomarkers (T-tau, P-tau, AV45) are normal, with no APOE4 risk allele.  \n\n**Diagnosis:** CN (Cognitively Normal)  \n**Confidence:** High",
