Neurologist Tests for Swallowing Disorder

Swallowing difficulty is also called dysphagia and is a problem that often originates in the brain. The brain is sent a signal that a swallowing action is needed. It then sends the signal via neurotransmitters to perform the act. However, different neurological disorders can inhibit swallowing since this transfer of information is disrupted.

Significance

• Swallowing disorders and difficulties are sometimes the indicators or first signs of a neurological disorder. Diagnosing patients early, through swallowing tests, can buy patients time for treatment of degenerative diseases such as Parkinson's, Lou Gehrig Disease and muscular dystrophy.

Types of Tests

• Neuromuscular diseases that manifest as swallowing disorders can be detected through single fiber electromyography or EMG. This is a test of muscle fiber stimulation to electrical impulses. A barium test and endoscope are used to rule out issues in the digestive system. Once this is done, neurological testing for specific disorders begins.

Trials

• A study began in April 2010 headed by Teresa Lever of Missouri University School of Health Professionals to detect the neurological source of swallowing disorders in patients already diagnosed with chronic neurological conditions. Lever's test will show which part of the brain is the culprit in the swallowing problems, in an effort to focus treatment for the condition.
