Parkinson's Parkinson's Speech and Communication 2 — Questions and Answers
Question 1: What is the medical term for the difficulty swallowing that affects a significant number of people with Parkinson's disease?
- Dysarthria
- Dysphagia (Correct answer)
- Dyspraxia
- Dysphonia
Correct answer: Dysphagia
Dysphagia is the medical term for difficulty swallowing, and it occurs in up to 80% of people with Parkinson's disease due to impaired motor control of the swallowing muscles.
Question 2: Which phase of the swallowing process is most commonly impaired in Parkinson's disease, increasing the risk of food or liquid entering the airway?
- Oral preparatory phase
- Oral transit phase
- Pharyngeal phase (Correct answer)
- Esophageal phase
Correct answer: Pharyngeal phase
The pharyngeal phase is most commonly impaired in Parkinson's disease because reduced and delayed muscle contractions in the throat increase the risk of aspiration.
Question 3: What serious pulmonary complication, directly resulting from dysphagia, is a leading cause of death in people with Parkinson's disease?
- Pulmonary embolism
- Aspiration pneumonia (Correct answer)
- Pulmonary fibrosis
- Chronic obstructive pulmonary disease
Correct answer: Aspiration pneumonia
Aspiration pneumonia, caused by food or liquid entering the lungs instead of the stomach, is one of the most common causes of death in advanced Parkinson's disease.
Question 4: Excessive drooling, known as sialorrhea, in Parkinson's disease is primarily caused by:
- Overproduction of saliva by the salivary glands
- Reduced frequency of automatic swallowing (Correct answer)
- Direct damage to the salivary glands from Parkinson's
- A side effect of levodopa medication
Correct answer: Reduced frequency of automatic swallowing
Sialorrhea in Parkinson's is not due to excess saliva production but rather due to reduced automatic swallowing frequency, causing saliva to pool in the mouth and spill out.
Question 5: Which healthcare professional is primarily responsible for evaluating and treating swallowing difficulties in patients with Parkinson's disease?
- Neurologist
- Gastroenterologist
- Speech-language pathologist (Correct answer)
- Occupational therapist
Correct answer: Speech-language pathologist
Speech-language pathologists (SLPs) are trained to assess and treat swallowing disorders (dysphagia) as well as speech and communication difficulties in Parkinson's patients.
Question 6: The 'chin tuck' technique, recommended during swallowing for some Parkinson's patients, is used primarily to:
- Strengthen neck flexor muscles over time
- Reduce the risk of food or liquid entering the airway (Correct answer)
- Increase the speed of swallowing
- Improve saliva production
Correct answer: Reduce the risk of food or liquid entering the airway
The chin tuck maneuver positions the airway to narrow its entrance, reducing the risk of aspiration by directing food and liquid away from the trachea.
Question 7: Which diagnostic test is considered the gold standard for evaluating swallowing function and aspiration risk in patients with Parkinson's disease?
- CT scan of the neck
- Videofluoroscopic swallow study (barium swallow study) (Correct answer)
- MRI of the brainstem
- Flexible endoscopic evaluation of swallowing (FEES)
Correct answer: Videofluoroscopic swallow study (barium swallow study)
The videofluoroscopic swallow study uses real-time X-ray imaging with barium contrast to visualize all phases of swallowing and identify aspiration, making it the gold standard assessment.
