With a Z-score of -0.44 (33.1th percentile), this represents normal volume ; hippocampal volume measures 9,217 mm³, 14.8% above the reference mean. With a Z-score of 1.48 (93.1th percentile), this represents mild enlargement; whole brain volume measures 1,145,400 mm³, 1.0% above the reference mean. With a Z-score of 0.14 (55.4th percentile), this represents normal volume ; entorhinal cortex volume measures 4,627 mm³, 8.5% above the reference mean. With a Z-score of 0.59 (72.3th percentile), this represents normal volume ; fusiform gyrus volume measures 20,077 mm³, 0.8% above the reference mean. With a Z-score of 0.07 (52.8th percentile), this represents normal volume ; middle temporal gyrus volume measures 23,331 mm³, 4.1% above the reference mean.

  "gpt_diagnosis": "Reasoning: The brain volume measurements are largely within normal ranges or slightly above average, with no significant atrophy in key regions like the hippocampus or entorhinal cortex. Cognitive scores (MMSE 29, MoCA 25) are within normal limits, and biomarkers (T-tau, P-tau, AV45) are normal, with no APOE4 risk allele.  \nDiagnosis: CN (Cognitively Normal)  \nConfidence: High",
