L5 Abnormal Swallow Physiology & Etiology Flashcards
T or F: The line between abnormal and normal is always clear
False
Why is knowing the incidence of dysphagia and your patient population important?
- anticipation of clinical caseload will help plan and allocate resources
- use figures to lobby for support from hospital admin
- knowledge of risk factors can improve Ax and Tx of disease via modification of risk factors or earlier detection of disease
What is the idea behind the surgical sieve technique?
a way to approach thinking about your patients symptoms to make sure you have considered all the contributing factors
Why is the surgical sieve technique useful for deglutition disorder clinicians?
- forces you to consider all factors
- consider why symptoms are presenting the way they are
- helps consider potential prognosis for return to baseline diet
- consider long, medium and short term prognosis
- helps reason through Tx plan
When going through the sieve what types of factors do you include
- neurological
- neoplastic
- traumatic
- inflammatory
- congenital
- degenerative
- autoimmune
- idiopathic
- environmental
- metabolic
- endocrinological
- haematological
- anatomical variations
- feeding ability and feeding techniques
- GI tract disorders
- Respiratory disorders
- Iatrogenic
Stroke and Parkinsons examples of _________ factors
neurological
Teeth loss due to aging, dementia and MS are examples of __________ factors
degenerative
Pierre-Robin Sequence and cerebral palsy are examples of __________ factors
congenital
The shape of the epiglottis and pyriform sinuses are examples of __________ factors
anatomical variations
COPD has a _______ course of dysphagia symptoms
chronic
Pharyngitis has a _________ course of dysphagia symptoms
acute
Parkinsons, MS and ALS all have a ________ course
degenerative
After a tongue resection, the dysphagia symptoms follow a ________ course
stabilizing
T or F: delirium and confusion in patients can affect their swallowing
true
Overall what are the 2 main etiology courses of dysphagia
- recuperative
- degnerative
List some examples that fall under recuperative etiology course
- stroke
- head and neck cancer
- cervical spine injury
- head injury
List some examples that fall under degenerative ethology course
- Parkinsons
- Alzheimers
- Multiple Sclerosis
- Huntington’s
When assessing dysphagia in stroke, using screening, clinical Ax and VFS, which method is most effective in identifying dysphagia in stroke
VFS
After first ischemic stroke _____% of individuals have dysphagia alone
49%
What are the 2 symptoms that co-occur with dysphagia after a ischemic stroke?
dysarthria
and aphasia
In an MRI study of brain lesions, which brain areas were associated with a high dysphagia
- lateral medulla (57%)
- medial medulla (40%)
- poins (43%)
Neurologic dysphasia may present in 3 ways. List them
1) Known neuro etiology & obvious symptoms
2) Known neuro etiology & no obvious symptoms (less common)
3) Unknown neuro etiology & obvious symptoms
List 4 common causes of neurologic related dysphagia
- stroke
- head injury
- progressive neurological (AD, PD)
- LMN disease
what is the incidence of dysphagia in acute stroke?
> 55%
What is meant by silent aspiration?
aspiration without any obvious signs of swallowing difficulty, such as coughing or difficulty breathing
T or F: the first swallow during a VFS or FEES is a reliable representation of a person’s swallowing
False - strange things can happen on the first bolus so we don’t push too much weight on the first swallow
What are the common dysphagia impairments in stroke
- Prolongation of oral and pharyngeal transit times (>2 sec)
- Delay and/or absent pharyngeal swallow
- Shorter laryngeal closure, UES opening & laryngeal elevation
- Site or side of lesions don’t always correlate well with symptoms
What are the common dysphagia impairments in head injury
- delayed and/or absent pharyngeal swallow
- reduced lingual control
- reduced pharyngeal clearance
- aspiration during and after swallow
- cognitive deficits impact on safety
What is the prevalence of dysphagia in MS?
24-65%
What is the prevalence of dysphagia in ALS
83%
What is the prevalence of dysphagia in Parkinsons
82%
T or F: In parkinsons patients, their report of swallowing difficulties is more sever than their actual dysphagia
FALSE - it Patient report tends to be less severe than their actual dysphagia
