Chapter 3 Flashcards
What is dysphagia a manifestation of what?
of another disease or disorder
What are the 2 basic divisions of the the nervous system?
upper motor neurons
lower motor nuerons
What is the basic foundation of upper motor neurons?
the central nervous system
What is the basic foundation of lower motor neurons?
the peripheral nervous system
Name 3 descriptive words used to describe MOTOR neurological disorders.
- spastic
- flaccid
- muscular weakness
Name 3 descriptive words used to describe SENSORY neurological disorders.
- taste
- smell
- consistency
Cortical/Subcortical =
Cognitive Function; initiation/inhibition
Brainstem =
Junction box / switch yard
Cerebellum =
Refinement
Spinal tract =
motor / sensory tract highway
Peripheral system =
exit the CNS
Muscle insertion =
Muscle action
Sensory initiation
Sensory uptake
What is subcortical function?
It is mainly giving directions and subconscious/sub-cortical fast unconscious reactions
What are the 2 areas of neurological swallowing disorders?
cortical and subcortical
Where is subcortical?
Anything beneath the cortex: thalamus, hypothalamus, brainstem, cerebellum. It is inside the orange peel.
Where is the cortical layer?
It is located on the outer layer of neural tissue and it surrounds the brain. It is the orange peel.
What are the 2 cortical function LOBES involved with swallow function?
frontal lobe
parietal lobe
What are the responsibilities of the frontal lobe during cortical functioning for swallowing?
MOTOR CONTROL
- intent
- initiation of movement
- coordination of movement
- movement of space and time
What are the responsibilities of the frontal lobe during cortical functioning for swallowing?
SENSORY
- Recognition
- Interpretation
Impairments due to cortical damage may vary for what 4 reasons?
- location of damage
- extent of damage
- type of damage (trauma vs. blunt force)
- unilateral vs. bilateral
What deficits should you consider when considering the swallowing effects of cortical damage?
- cognitive deficit
2. physical deficit
When you are assessing someone with cortical damage, what might assessment be “drawing the line” between?
Whether or not the patient gets to eat.
What are the 3 largest categories of neurological cortical disorders?
- stroke
- dementia
- traumatic brain injury
What is a stroke from cortical damage?
- A CVA that does not include the brainstem.
2. Anoxia damage.
What is dementia?
generalized neurologic degeneration
What is a traumatic brain injury?
- closed or open head injury
2. vascular, tissue, or neurologic damage
What do know about swallowing disorders if a hemisphere stroke occurs?
- swallowing disorders pertaining to left side/right side are not entirely defined.
What happens to swallowing if someone has a left hemisphere stroke?
oral apraxia
Define oral apraxia.
Voluntary movement disorder of sequence.
Inability to sequence motor movement voluntarily.
Since oral apraxia is a disorder of voluntary motor sequencing what should you remember for swallowing evaluations with these patients?
Patients do better feeding themselves. THIS DOES NOT MAKE SENSE. ASK SOMEONE ABOUT THIS.
What happens with swallowing during a right side hemisphere stroke?
- oral transit problems
- delay in pharyngeal swallow
- laryngeal elevation delayed
What happens to swallowing if a patient has multiple strokes?
- There is an overall multiplication of symptoms.
- More severe oral transit
- reduced laryngeal elevation/closure
- treatment is difficult
What is the overall recovery like for someone who had his/her first stroke?
- full oral intake recovery usually takes 3-4 weeks
2. most progress occurs within 3-4 weeks
Name 6 other factors that affect stroke patients recovery.
- comorbidities
- diabetes
- neuropathies
- prior CVA
- pulmonary disorders in PNEUMONIA
- medications
What are your goals as an SLP for a patient in stroke swallow treatment?
- ensure that they swallow their food SAFELY
- keep in mind that they have to MEET NUTRITION
(i.e. double swallow, thickened liquids)
NOTE: honey thickened liquids are not the answer for everyone
Don’t get stuck in a box during stroke swallow treatment. HOW should dysphagia treatment CHANGE over time?
Changes in:
- bolus volume
- bolus viscosity
- bolus taste (sour bolus)
What should treatment include for a head and neck patient?
- head and body positions
2. put your head down, turn your head to the side
- For most strokes that cause a delay in the pharyngeal swallow, what might be the most difficult for the patient to swallow?
- What might be the best to start off with?
- thin liquids might be the most difficult
- a puree might be the best to start of with (i.e. pudding bolus
OR - follow IMBSP protocol
List a few examples reasons for cortical damage dementia?
- alzheimer’s disease
- alcoholism
- cardiovascular disease
Dementia is a progressive deterioration of what?
cognitive abilities
What is negatively effected because of cortical damage dementia?
- memory
- judgement
- apraxia
