What is the Wallenberg syndrome?

Wallenberg syndrome (WS) is a neurological disorder that is due to damage to the lateral portion of the medulla oblongata (i.e., the lateral medullary syndrome). WS is typically due to ischemia from a vertebral artery or posterior inferior cerebellar artery infarction.

What is Wallenberg syndrome and what are the symptoms?

Summary. 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.

Why is it called Wallenberg syndrome?

Named after Adolf Wallenberg in 1895, this neurological condition is characterized by lateral medullary infarction resulting from an occlusion of the posterior inferior cerebellar artery (PICA) or the vertebral artery.

Is Wallenberg syndrome a stroke?

Wallenberg’s syndrome is a neurological condition caused by a stroke in the vertebral or posterior inferior cerebellar artery of the brain stem.

Can you recover from lateral medullary syndrome?

As a result, dysphagia following a lateral medullary stroke (LMS) is often more severe and spontaneous recovery may not completely restore the swallowing function. It may persist for life time or may take months or years to resolve [2].

Does Wallenberg syndrome go away?

The long-term outlook for people with Wallenberg syndrome is fairly positive. A successful recovery depends on where the stroke happened in the brainstem. It also depends on how much damage occurred. Some people can recover between a few weeks to six months after treatment.

How common is Wallenberg syndrome?

Approximately 800,000 people have an acute stroke each year in the United States, notes StatPearls, and 83 percent of these are ischemic strokes. Twenty percent of ischemic strokes occur in the posterior circulation, leading to an estimated 60,000 new cases of Wallenberg syndrome each year.

How is lateral medullary syndrome diagnosed?

Since lateral medullary syndrome is often caused by a stroke, diagnosis is time dependent. Diagnosis is usually done by assessing vestibular-related symptoms in order to determine where in the medulla that the infarction has occurred.

Is Wallenberg syndrome rare?

Wallenberg syndrome is a rare condition in which an infarction, or stroke, occurs in the lateral medulla.

What is Wallenberg syndrome?

Wallenberg syndrome is the most prevalent posterior ischemic stroke syndrome. There are nearly 800,000 patients who suffer from an acute stroke each year in the United States. Of these, 83% are ischemic strokes.

Can physiotherapy help people with Wallenberg syndrome?

Repetitive transcranial magnetic stimulation has shown promise in aiding the rehabilitation of the dysphagia that often presents in Wallenberg Syndrome. Physiotherapy can play an essential role in helping those with Wallenberg Syndrome regain their functional independence and reintegrate into their communities.

What increases my risk for Wallenberg syndrome?

The greatest risk factor for Wallenberg Syndrome is currently believed to be large artery atherosclerosis, which is often linked to a history of hypertension, diabetes, and smoking. The most common cause of Wallenberg Syndrome is an ischemic stroke in the VA or PICA of the brainstem, often the result of a thrombus or embolism.

What is Wallenberg syndrome of posterior ischemic stroke?

Wallenberg syndrome, also known as “ lateral medullary syndrome ” or “ posterior inferior cerebellar artery ( PICA) syndrome”, is the most prevalent posterior ischemic stroke syndrome.
