With a Z-score of -0.40 (34.6th percentile), this represents normal volume ; whole brain volume measures 879,917 mm³, 14.5% below the reference mean. With a Z-score of -1.90 (2.9th percentile), this represents moderate atrophy. ",

Cognitive scores (MMSE 23, MoCA 23) are borderline for mild impairment, but age (88.2) and absence of APOE4 reduce Alzheimer's likelihood.  \nDiagnosis: MCI  \nConfidence: Medium",
