Wallenberg's Syndrome

Wallenberg's syndrome is a neurological disorder. It is characterized by swallowing difficulties and hoarseness which results from paralysis of a portion of the vocal cord.


The disorder is generally caused by a blockage in a vertebral or cerebellar artery.


Symptoms may include:

  • Dizziness.

  • Loss of pain or temperature sensitivity.

  • Some paralysis of the facial muscles.

  • Loss of taste.

Patients with this syndrome often report an unsettling tilt of their environment. This affects their balance.


Treatment for this syndrome is symptomatic. If swallowing is greatly impaired, a feeding tube may be needed. Therapy and intraoral appliances may aid speech and swallowing. In some cases, medication reduces or eliminates pain.

Individuals with this syndrome may have a lessening of their symptoms as a result of medical intervention. For some patients, symptoms go away after a few weeks of treatment.
