Alerting, Orienting, Executive Control and Language Function in Post-stroke Aphasia Patients

Background: Aphasia is frequently observed in post-stroke patients, and this population usually presents attention impairment. Attention considered to play an important role the language recovery of patients with Post-Stroke (PSA). However, it no idea whether function correlates performance. In our study, we investigated association between PSA patients. Methods: This cross-sectional study was performed from September 2020 May 2021. A total 26 healthy people without neurological disorders were recruited study. And demographic, performance, performance recorded. The Battery Chinese (ABC) applied assess network tests used measure scores compared people. correlation analysis stepwise linear regression are explore relationship group. Results: (male/female = 21:5) enrolled mean ages 50.00 ± 9.01 years, 48.88 7.01, respectively. According ABC, 14 (53.85%) experienced Broca’s aphasia. accordance Network Test (ANT), there significant differences accuracy reaction time group control (all P<0.05). Orienting RT alerting inverse efficiency (IE) two groups. spearman revealed that executive associated aphasia severity grade, repetition correlated alerting, auditory comprehension orienting. after analysis, alone emerged as a predictor comprehension. Alerting IE orienting predictors repetition. Conclusions: results suggest among items (aphasia comprehension, repetition) related three specific functions: orienting, control. Disentangling mechanism deficits may provide supplement for rehabilitation strategies
