With a Z-score of 0.94 (82.7th percentile), this represents normal volume ; hippocampal volume measures 7,435 mm³, 3.2% below the reference mean. With a Z-score of -0.36 (35.8th percentile), this represents normal volume ; whole brain volume measures 1,088,900 mm³, 5.8% above the reference mean. With a Z-score of 0.72 (76.5th percentile), this represents normal volume ; entorhinal cortex volume measures 3,541 mm³, 9.0% below the reference mean. With a Z-score of -0.70 (24.2th percentile), this represents normal volume ; fusiform gyrus volume measures 17,846 mm³, 2.0% below the reference mean. With a Z-score of -0.23 (41.1th percentile), this represents normal volume ; middle temporal gyrus volume measures 22,494 mm³, 9.6% above the reference mean.

Cognitive scores (MMSE: 26, MoCA: 25) are also within normal limits for age, and there is no APOE4 genetic risk factor.  \n\n**Diagnosis:** CN (Cognitively Normal)  \n**Confidence:** High",
