What is Wallenberg syndrome?
Wallenberg’s syndrome is a neurological condition caused by a stroke in the vertebral or posterior inferior cerebellar artery of the brain stem.
What is Wallenberg syndrome symptoms?
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.
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.
What type of stroke is Wallenberg syndrome?
Wallenberg syndrome is often caused by an ischemic stroke. Ischemic strokes account for about 87 percent of all strokes, according to the American Stroke Association.
Is Wallenberg syndrome a disability?
Complications of Wallenberg Syndrome Stroke syndromes can cause permanent disability and affect normal daily functioning, per StatPearls. The most common complications of posterior circulation strokes include: Aspiration pneumonia.
Why does diplopia occur in lateral medullary syndrome?
Diplopia in Wallenberg’s syndrome is considered to be caused by a lesion involving the otolith-ocular system. Vertical diplopia is simply explained by ocular skew deviation due to a lesion involving the vestibular nucleus; in which the affected eye becomes deviated inferiorly.
Is Wallenberg syndrome permanent?
Are there any other names for Wallenberg syndrome?
Other Names: Lateral medullary syndrome; Posterior inferior cerebellar artery syndrome; PICA syndrome; Lateral medullary syndrome; Posterior inferior cerebellar artery syndrome; PICA syndrome; Vertebral artery syndrome; Wallenberg’s syndrome See More.
How are magnetic resonance imaging used in Wallenberg’s lateral medullary syndrome?
Four patients with a clinical diagnosis of Wallenberg’s lateral medullary syndrome were studied with both Magnetic Resonance Imaging (MRI) and cranial Computed Tomography (CT). Using transverse images and both T1 and T2–weighted sequences, MRI demonstrated a medullary infarction not seen on CT in all four cases.
What is the infarcted area of Wallenberg syndrome?
The syndrome can also be due to occlusion of the vertebral artery, or the inferior, middle, or superior medullary vessels. Anatomically the infarcted area in Wallenberg syndrome is supplied by the posterior inferior cerebellar artery (PICA). It turns out occlusion of the PICA accounts for only a small number of cases.
How does transcranial magnetic stimulation help 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.
