Bulbar palsy is a condition that affects the nerves controlling the muscles involved in speech and swallowing. It’s caused by damage to the nerves in the brainstem, which is the part of the brain that controls basic bodily functions like breathing and heart rate.
Types:
There are two main types of bulbar palsy:
- Progressive Bulbar Palsy (PBP): This type gets worse over time and is usually caused by diseases like ALS (Amyotrophic Lateral Sclerosis) or motor neuron disease.
- Non-Progressive Bulbar Palsy: This type does not get worse over time and is often caused by injuries or infections.
Causes:
- ALS (Amyotrophic Lateral Sclerosis)
- Stroke
- Brainstem tumors
- Traumatic brain injury
- Infections such as polio or meningitis
- Multiple sclerosis
- Guillain-Barré syndrome
- Parkinson’s disease
- Myasthenia gravis
- Botulism
- Wilson’s disease
- Progressive supranuclear palsy
- Chronic obstructive pulmonary disease (COPD)
- Diabetes
- Lyme disease
- Radiation therapy to the head and neck
- Lead poisoning
- Alcoholism
- Drug overdose
- Genetic disorders
Symptoms:
- Difficulty speaking or slurred speech
- Difficulty swallowing or choking
- Weakness in the tongue or facial muscles
- Drooling
- Hoarse voice
- Nasal regurgitation (food or liquid coming out of the nose)
- Uncontrolled crying or laughing
- Weight loss due to difficulty eating

- Feeding schedules: Establishing regular meal times and avoiding distractions during meals can improve focus and swallowing function.
- Sensory stimulation: Using taste, smell, or temperature variations to stimulate the swallowing reflex.
- Education and counseling: Providing information and support to patients and caregivers about managing symptoms and coping strategies.
- Oral motor exercises: Strengthening exercises for the muscles involved in speech and swallowing.
- Neuromuscular electrical stimulation: This therapy uses electrical currents to stimulate muscle contractions and improve swallowing function.
- Modified feeding techniques: Adjusting the pace and size of food bites to reduce the risk of choking.
- Hydration management: Monitoring fluid intake and using hydration strategies like frequent sips or ice chips.
- Postural techniques: Positioning the body in specific ways to optimize swallowing function.
- Cognitive-linguistic therapy: Addressing cognitive deficits that may impact communication and swallowing.
- Social support groups: Connecting with others facing similar challenges can provide emotional support and practical advice.
- Oral care protocols: Implementing routines for oral hygiene maintenance to prevent complications like dental decay or infections.
- Energy conservation techniques: Managing activities and rest periods to conserve energy and prevent fatigue.
- Feeding assistance programs: Accessing community resources or home care services for help with meal preparation and feeding.
- Adaptive equipment training: Learning to use assistive devices effectively for eating, drinking, and communication.
- Texture-modified diets: Following guidelines for soft or pureed foods to accommodate swallowing difficulties.
- Breathing exercises: Practicing deep breathing and coughing techniques to clear the airways and prevent respiratory infections.
