With a Z-score of -1.34 (9.1th percentile), this represents mild atrophy; whole brain volume measures 887,800 mm³, 4.4% below the reference mean. With a Z-score of -0.52 (30.1th percentile), this represents normal volume . ",

The MMSE score of 20 suggests cognitive impairment, but the absence of APOE4 reduces genetic risk.  \nDiagnosis: MCI (Mild Cognitive Impairment)  \nConfidence: Medium",
