Plasma biomarkers are associated with agitation and regional brain atrophy in Alzheimer's disease.


ABSTRACT: This study investigated the relationships among plasma biomarkers, regional brain atrophy, and clinical symptoms in patients with Alzheimer's disease (AD; n?=?177), mild cognitive impairment (MCI; N?=?60) and controls (n?=?108). The Mini-Mental Status Examination (MMSE), Clinical Dementia Rating (CDR), and Neuropsychiatric Inventory (NPI) subscales were administered to subjects. Magnetic resonance imaging was performed and medial temporal atrophy (MTA) and posterior atrophy (PA) were assessed visually. We examined associations among cognition, NPI score, plasma ?-amyloid (A?) and clusterin levels, and regional brain atrophy in patients with AD by regression analysis. The mean MTA score was associated with the plasma A?1-42/A?1-40 ratio (r?=?0.38, p?=?0.01) and with MMSE scores (r?=?0.43, p?
