Wallenberg syndrome is a condition that affects the nervous system. Signs and symptoms may include swallowing difficulties, dizziness, hoarseness, nausea and vomiting, nystagmus, and problems with balance. Some people have uncontrollable hiccups, loss of pain and temperature sensation on one side of the face, and/or weakness or numbness on one side of the body. Wallenberg syndrome is often caused by a stroke in the brain stem. Treatment addresses each symptom and may include a feeding tube for swallowing problems, speech and/or swallowing therapy, and medication for pain. While some people’s symptoms may improve within weeks or months, others may have long-term neurological problems.
