With a Z-score of 1.19 (88.3th percentile), this represents mild enlargement; whole brain volume measures 1,067,980 mm³, 1.1% below the reference mean. With a Z-score of -0.14 (44.5th percentile), this represents normal volume . ",

The MMSE (21) and MoCA (20) scores suggest cognitive impairment, but the absence of APOE4 reduces genetic risk for Alzheimer's.  \nDiagnosis: MCI (Mild Cognitive Impairment)  \nConfidence: Medium",
