With a Z-score of -0.71 (23.8th percentile), this represents normal volume ; hippocampal volume measures 7,637 mm³, 7.3% above the reference mean. With a Z-score of 0.67 (75.0th percentile), this represents normal volume ; whole brain volume measures 972,481 mm³, 0.2% below the reference mean. With a Z-score of -0.03 (48.9th percentile), this represents normal volume ; entorhinal cortex volume measures 3,759 mm³, 2.3% above the reference mean. With a Z-score of 0.14 (55.7th percentile), this represents normal volume ; fusiform gyrus volume measures 15,852 mm³, 6.8% below the reference mean. With a Z-score of -0.62 (26.7th percentile), this represents normal volume ; middle temporal gyrus volume measures 19,682 mm³, 2.7% above the reference mean.

The MMSE score of 30/30 indicates no cognitive impairment, and the absence of APOE4 alleles reduces genetic risk for Alzheimer’s.  \n\n**Diagnosis:** CN (Cognitively Normal)  \n**Confidence:** High",
