Objective Affective disorders are prevalent in different somatic conditions and influence somatic symptom bother and quality of life. Mood and anxiety disorders impact patients' compliance and adherence to treatment. This systematic review summarizes published studies on affective complaints in patients with oropharyngeal dysphagia (OD) in order to determine the quality of studies concerning any association of OD with symptoms of depression and/or anxiety. Methods A literature search was carried out using electronic databases Embase, Medline, Web-of-science, PsycINFO, Cochrane Library, and Google scholar. Two reviewers made the preselecting cut by screening all articles on title and abstract and independently screened the full texts of this initial set of articles. Methodological quality of the studies that met the inclusion criteria was assessed independently. Results Twenty-six articles were included in the analysis after full-text screening and by applying the inclusion and exclusion criteria. All studies concluded that symptoms of depression were associated with impaired swallowing function, and 9 out of 12 studies concluded that symptoms of anxiety were associated with functional impairment of swallowing. The reviewers found heterogeneous outcomes and methodological limitations, which prevented data from pooling. Conclusion Although no meta-analytic conclusions can be drawn, it appears that symptoms of anxiety and depression are common in OD. Caregivers have to be aware of this in order to detect affective comorbidity. Given that affective conditions influence patients' treatment adherence and compliance, integrated care approaches should be advocated in case of comorbidity. Studies on treatment effect are lacking and well-designed prospective research is needed.
