With a Z-score of -1.12 (13.2th percentile), this represents mild atrophy; whole brain volume measures 1,087,730 mm³, 5.7% above the reference mean. With a Z-score of 0.71 (76.1th percentile), this represents normal volume . ",

The MMSE score of 23 suggests mild cognitive impairment, but the absence of APOE4 reduces Alzheimer's risk.  \n**Diagnosis:** MCI  \n**Confidence:** Medium",
