Table 3 Dysphagia classification, description of disorders and symptoms

From: Swallowing disorders in tracheostomised patients: a multidisciplinary/multiprofessional approach in decannulation protocols

Type of dysphagia Disorder Symptom
Neurogenic dysphagia in the vegetative state Typical of patients who present a permanent vegetative state  
Neurogenic dysphagia from cognitive/behavioural deficit Patients whose cognitive/behavioural deficits have a decisive effect on their ability to feed by mouth  
Neurogenic dysphagia for fluids Patients are able to eat by mouth with a free diet These patients present dysphagia for fluids and it is essential to introduce thickened liquids, with Aquagel, through parenteral or enteral therapy (NG-tube or PEG).
Mixed neurogenic dysphagia Patients are not able to safely take more than one consistency Patients who are fed with a semisolid diet and take thickened liquids, with Aquagel or through parenteral or enteral therapy (NG-tube or PEG) fall into this category.
Neurogenic dysphagia for solids Patients are fed with a semisolid diet and fluids are administered by mouth The subject cannot eat foods with a solid consistency due to inability to chew, difficulty in forming the bolus or inhalation. Dysphagia must be determined by a neurological and not a mechanical deficit.
