Investigation of neurogenic dysphagia in commonly seen neurological diseases

OpenAlex İngilizce

Neurological disorders lead to varying degrees of impairment in the functions of vital swallowing structures, such as the cortex, cerebellum, brainstem, cranial nerves, and muscles. Neurogenic dysphagia is observed in approximately 50% of common neurological disorders such as stroke, multiple sclerosis, and Parkinson’s disease. Although the pathophysiology and course of the disease vary, dysphagia may occur at any stage of swallowing, including oral preparation, oral, pharyngeal, and esophageal phases. Neurogenic dysphagia ranks among the top symptoms that restrict patients’ independence in daily life activities, reduce their quality of life and increase morbidity and mortality rates. Despite being a prevalent and highly impactful symptom among patients, neurogenic dysphagia can go unnoticed among the multiple symptoms experienced by neurological disorders due to their nature. It is important to be aware of disease-specific risk factors for the early detection of neurogenic dysphagia. Overlooked dysphagia can lead to complications such as aspiration pneumonia, dehydration, malnutrition, and weight loss. Among these complications, aspiration pneumonia is the most common, requiring attention due to its recurrent hospitalizations, inpatient treatment, and high healthcare costs. Many patients exhibit common neurogenic dysphagia symptoms such as drinking liquids in small sips, cutting solid foods into small pieces, decreased appetite, and prolonged meal times. The aim of this study is to examine various aspects of neurogenic dysphagia in different neurological disorders, including its etiology, risk factors, symptoms, and prevalence.
