With a Z-score of 1.31 (90.5th percentile), this represents mild enlargement; whole brain volume measures 945,435 mm³, 3.0% below the reference mean. With a Z-score of -0.38 (35.3th percentile), this represents normal volume . ",

The MMSE score of 24 suggests mild cognitive impairment, and the presence of two APOE4 alleles increases Alzheimer's risk.  \nDiagnosis: MCI (Mild Cognitive Impairment)  \nConfidence: Medium",
