Abstract

Introduction Deep brain stimulation (DBS) is an established treatment for Parkinson's disease (PD). However, there is little evidence regarding the effect of DBS on dysphagia.

Objective To assess the swallowing and quality of life of individuals with PD before and after DBS surgery.

Methods Our sample consisted of people who had undergone DBS surgery in a referral hospital in the state of Rio Grande do Sul, Brazil. The inclusion criteria were a diagnosis of PD and having undergone DBS surgery. A cognitive screening, through a questionnaire about depression and quality of life, was conducted. Evaluations of each patient's swallowing were performed before and after surgery. The assessment consisted of anamnesis, clinical assessment, the Functional Oral Intake Scale, clinical evaluation of swallowing, and the Hoehn and Yahr scale.

Results The sample included 10 individuals, all male, with a mean age of 57.3 years (±4.7), a mean disease duration of 13.0 years (±2.4), and mean level education of 8.1 years (±4.0). In the clinical evaluation of the swallowing, a significant improvement after DBS was not observed. However, little changes in the signs and symptoms of dysphagia that had a positive impact on the quality of life were observed. Furthermore, there was no relation between the patients' motor subtype and swallowing pre- and post-DBS.

Conclusion There was an improvement in the quality of life of the patients after DBS. However, the improvement in the clinical signs and symptoms of dysphagia did not cause an overall improvement in the swallowing function.
