With a Z-score of 1.75 (96.0th percentile), this represents moderate enlargement; whole brain volume measures 901,019 mm³, 16.5% below the reference mean. With a Z-score of -2.15 (1.6th percentile), this represents significant atrophy. ",

The MMSE score of 26 is borderline, but the structural changes and APOE4 homozygosity strongly suggest Alzheimer's pathology.  \nDiagnosis: Dementia  \nConfidence:",
