ABSTRACT
Several factors contribute to the swallowing difficulties encountered in patients with neurogenic dysphagia. These include weakness of the oral musculature and tongue movements, failure to form a cohesive food bolus, reduced sensitivity of the pharyngeal receptors, and buccolingual apraxia. Although the abnormalities of swallowing associated with neurological disease predominantly affect the oropharyngeal phase, occasionally neurogenic dysphagia may result from disorders of innervation of the oesophagus.
