With a Z-score of -1.39 (8.2th percentile), this represents mild atrophy; whole brain volume measures 968,563 mm³, 5.9% below the reference mean. With a Z-score of -0.77 (22.0th percentile), this represents normal volume . ",

Cognitive impairment (MMSE 20) is present, but normal Aβ, T-tau, and P-tau levels argue against Alzheimer's pathology.  \nDiagnosis: MCI (likely non-Alzheimer's etiology)  \nConfidence: Medium",
