Pseudobulbar palsy
Pseudobulbar palsy (pronounced: soo-doh-bul-bar pahl-see) is a medical condition characterized by the inability to control facial movements such as chewing and speaking. The term is derived from the Greek words "pseudo" meaning false, "bulb" referring to the brainstem, and "palsy" meaning weakness.
Definition
Pseudobulbar palsy is a type of bulbar palsy, which refers to a group of neurological disorders affecting the nerves responsible for swallowing, speaking, and other functions associated with the mouth and throat. Unlike bulbar palsy, pseudobulbar palsy is characterized by the dysfunction of the upper motor neurons that control the muscles involved in these functions.
Symptoms
The symptoms of pseudobulbar palsy can vary but often include difficulty swallowing (dysphagia), slurred speech (dysarthria), and emotional lability, which is characterized by uncontrollable episodes of laughing or crying.
Causes
Pseudobulbar palsy is often caused by conditions that damage the upper motor neurons, such as stroke, multiple sclerosis, or motor neuron disease. It can also occur as a result of traumatic brain injury.
Treatment
Treatment for pseudobulbar palsy typically involves managing the symptoms and may include speech therapy, physical therapy, and medications to control muscle stiffness and emotional lability.
