What is dysphagia? ?
Dysphagia is characterized by abnormality in the transfer of a bolus from the mouth to the stomach.
What type of stage might the abnormality occur?
Abnormalities may involve the oral, pharyngeal, or esophageal stage of swallowing sequence.
What are the ranges of impairment from delay in transfer?
Impairments ranges from delay in transfer to absence of transfer and includes misdirections of transference as in airway penetration.
What is the more functional definition of dysphagia?
Dysphagia is a condition resulting from interruption in either eating pleasure or the maintenance of nutrition and hydration.
Describe the 3 roles of the speech-language pathologist in the management of dysphagia?
1) The SLP teach patients compensatory (other ways) techniques for eating and swallowing. 2)They also make recommendations about diets, specifying the consistency of foods that a patient can safely consume, e.g. thick/thin, liquids, puree/mechanical soft, etc. 3) SLPs assess the swallowing abilities of patients through bed-side evaluations, and also through the use of radiographic techniques when neccessary.
Discuss the causes of dysphagia?
Swallowing patients neurological status may change due to additional strokes. Patients may be treated for dysphagia after suffering a stroke or after traumatic brain injury. Other causes of dysphagia include brain tumor, spinal cord injuries, and progressive diseases like Parkinson's Disease, and Mulitiple Sclerosis.
Discuss the incidence of dysphagia?
The exact incidence of dysphagia in population of adults with neurogenic disorders is unknown. 1/3 of such patients has some type of dysphagia (Rehab Institue of Chicago).
Discuss incidences of dysphagia?
According to Cherney, stroke was most common cause of dysphagia, accounting for about half of the cases.
What is bilateral cortical stroke?
Is a type of CVA most likely to cause dysphagia.
Which unilateral side causes more dysphagia? Why?
Unilateral right hemisphere cause more dysphagia than do unilateral left hemisphere. This probably occurs b/c right hemisphere lesion often cause implusively poor judgement and reduced ability to follow compensatory strategies.
What is the second most common cause of dysphagia?
TBI being the cause of about 20% of swallowing problems seens at that facility. Overall about 25% of patients suffering from TBI has some type of dysphagia. TBI has more often causes severe dysphagia.
What is a stroke or cerebral vascular accident?
Stroke and CVA is a temporary or permanent loss of functioning brain
What are the two types of strokes?
1. Full or partial blockage of an artery (Ischemic strokes)
2. Ruptures of intracranial blood vessels. Approximately 300,000 pll have strokes in U.S (Hemmorphage).
What factors increase stroke?
1. Primary Hypertension- greatly increases a person's risk of suffering a CVA. Primary Hypertension refers elevated diastrolic pressure.
Smoking and obesity increase risk of vascular probs in those who have hypertension.
2. High Cholesterol Levels (hypercholesterolemia). High Density Lipoprotein (HDL) or Low Density Lipoprotein (LDL).
What is diastrolic blood pressure and systolic blood pressure?
Systolic blood pressure (upper number) is measured when the heart is contracting, while diastolic blood pressure (lower number) is measured when the heart muscle is between beats or pressure in arteries as of the heart in rest.
