Abstract
Increases in plasma of β-amyloids (Aβ) and tau proteins have been noted in patients with Alzheimer’s dementia (AD). Our study investigated the associations of plasma Aβ and tau proteins with dementia in stroke patients. This cross-sectional study recruited 24 controls (mean age: 67.4 ± 7.5 years, 33.3% male), 27 stroke patients without dementia (mean age: 70.7 ± 6.9 years, 60.7% male), 34 stroke patients with dementia (mean age: 78.3 ± 5.3 years, 45.5% male, Clinical Dementia Ranking (CDR): 1.46 ± 0.63), and 21?AD patients (mean age: 77.1 ± 9.1 years, 42.9% male, CDR: 1.43 ± 0.60) from a medical center. Dementia was defined as a CDR scale score of ? 1. The plasma levels of Aβ-40, Aβ-42, and tau were analyzed using immunomagnetic reduction. One-way analysis of variance was used to compare the differences in measured protein levels between the groups. The results indicated that plasma levels of tau and Aβ-42, but not Aβ-40, in stroke patients were significantly higher than in the controls. After adjustment for age, sex, diabetes mellitus, hypertension, and hyperlipidemia, only plasma level of Aβ-42 remained significantly higher in stroke patients with dementia than in those without dementia (OR 1.85, 1.25–2.75, p = 0.002). In summary, our results suggest that plasma Aβ-42 is a potential biomarker for dementia in stroke patients. ? 2018, Springer Science+Business Media, LLC, part of Springer Nature.
