Association between dysphagia and symptoms of depression and anxiety after ischemic stroke

Abstract

AbstractBackground and purposeDysphagia is associated with poor outcome, higher mortality, reduced quality of life, and social isolation. We investigate the relationship between swallowing impairment and symptoms of anxiety and depression after ischemic stroke.MethodsConsecutive patients with ischemic stroke participating in the prospective STROKE‐CARD Registry study from 2020 to 2022 were assessed for dysphagia on hospital admission (clinical swallowing assessment) and for persistence until discharge and 3‐month follow‐up (SINGER Independency Index). Anxiety and depression symptoms were recorded using Beck Depression Inventory (BDI) and Hospital Anxiety and Depression Scale (HADS) at 3‐month follow‐up.ResultsOf 648 patients, 19.3% had dysphagia on admission, persisting in 14.8% at discharge and 6.8% at 3‐month follow‐up. With the presence or duration of dysphagia (no dysphagia, dysphagia at baseline, at discharge, at 3 months), score (mean ± SD) increased on the BDI (7.9 ± 6.7, 12.5 ± 8.7, 13.5 ± 9.0, 16.5 ± 10.2), HADS‐D (4.4 ± 3.7, 7.1 ± 4.2, 7.7 ± 4.4, 9.8 ± 4.3), and HADS‐A (4.4 ± 3.5, 5.4 ± 3.6, 6.0 ± 3.6, 7.0 ± 3.6). In linear regression analysis adjusting for age, sex, diabetes, dementia, and either functional disability or stroke severity, BDI and HADS‐D scores were significantly higher in patients with dysphagia across all points in time (admission, discharge, 3‐month follow‐up). An independent association with HADS‐A scores was only evident in patients with persisting dysphagia after 3 months. Patients with dysphagia were more likely to receive antidepressants, antipsychotics, or benzodiazepines at discharge and 3‐month follow‐up.ConclusionsDysphagia after stroke is common and severely affects psychosocial functioning of individuals. Our results highlight swallowing impairment as an independent predictor for poststroke depressive and, to a lesser extent, anxiety symptoms.
