Document Summary

What are the defining characteristics of adult dysphagia: 1. Determined by the site of which the swallowing system breaks down. Slp is primarily concerned with disorders in the oral preparatory, oral, and pharyngeal phases also called oropharyngeal dysphagia. Gastroenterologists, internists, radiologists, and other professionals study and treat esophageal dysphagia, resulting from impairments of the esophageal phase of swallowing. Breakdowns in the oral preparatory phase occur when the lips, tongue, cheeks, and mandible do not function as they should. Inefficient oral preparation because of reduced range of motion of the tongue and/or weakness of the tongue. Impaired sensitivity of the tongue, lips, and other oral structures that hinders food positioning and management. Formed bolus moves to the back of the mouth toward the pharynx to trigger the swallowing. Oral phase dysphagia occurs in people with strokes or als: difficulty moving the bolus to the pharynx. Inability to adequately control movement of the bolus: delayed initiation of the bolus movement.
