Swallowing disorders, or dysphagia, affect over 30% of multiple sclerosis (MS) patients. Early assessment is crucial, especially for those with longer disease duration and greater neurological impairment.
Area of Science:
- Neurology
- Gastroenterology
- Speech-Language Pathology
Background:
- Swallowing disorders (dysphagia) are prevalent in multiple sclerosis (MS).
- Dysphagia complications contribute to morbidity and mortality in advanced MS stages.
- Dysphagia in MS often lacks adequate clinical attention.
Purpose of the Study:
- To determine the prevalence of various swallowing disorders in MS patients with mild to moderate disability.
- To identify associations between patient clinical/demographic features and dysphagia.
- To highlight the need for dysphagia assessment in MS care.
Main Methods:
- Screening of swallowing function in 101 consecutive MS patients using the Northwestern Dysphagia Patient Check Sheet.
- The screening tool identifies pharyngeal stage disorders, aspiration, oral stage disorders, and pharyngeal delay.
- Dysphagia was defined as the presence of at least one of these four disorders.
Main Results:
- 31.7% of MS patients screened had dysphagia.
- Pharyngeal stage disorders were most common (28.7%), followed by aspiration (6.9%), oral stage disorders (5%), and pharyngeal delay (1%).
- Dysphagia correlated significantly with longer disease duration, greater cerebellar impairment, and higher Expanded Disability Status Scale (EDSS) scores.
Conclusions:
- Dysphagia is a significant issue in MS patients, even with mild to moderate disability.
- Assessment and management of swallowing function are critical for MS patients.
- Particular attention should be paid to MS patients with high EDSS scores, severe cerebellar dysfunction, and long disease duration.
