With a Z-score of -0.28 (38.9th percentile), this represents normal volume ; hippocampal volume measures 8,427 mm³, 5.0% above the reference mean. With a Z-score of 0.50 (69.1th percentile), this represents normal volume ; whole brain volume measures 1,149,430 mm³, 1.3% above the reference mean. With a Z-score of 0.19 (57.4th percentile), this represents normal volume ; entorhinal cortex volume measures 4,641 mm³, 8.9% above the reference mean. With a Z-score of 0.61 (73.0th percentile), this represents normal volume ; fusiform gyrus volume measures 21,628 mm³, 8.6% above the reference mean. With a Z-score of 0.72 (76.4th percentile), this represents normal volume ; middle temporal gyrus volume measures 24,484 mm³, 9.2% above the reference mean.

Cognitive scores (MMSE and MoCA) are also within normal limits, and there is no APOE4 genetic risk factor.  \nDiagnosis: CN (Cognitively Normal)  \nConfidence: High",
