What is Wallenberg’s syndrome?
Wallenberg’s syndrome is a neurological disorder describing symptoms that result from the disruption of blood flow to the brainstem.
Early intervention is crucial, and Wallenberg’s syndrome is diagnosed through examination and brain imaging.
The outcome can vary depending on the severity. On the whole, people progress through recovery with rehabilitation support and lifestyle changes.
What causes Wallenberg’s syndrome?
Wallenberg’s syndrome is most commonly caused by an ischaemic stroke to the lateral medulla oblongata of the brainstem. For this reason, it is also known as lateral medullary syndrome.
Occlusion of the posterior inferior cerebellar artery (PICA) or the vertebral artery is the main reason.
This can be due to trauma or blockage of blood supply to the brain from plaque build-up or clots in the arteries.
What are the symptoms of Wallenberg’s syndrome?
The symptoms of Wallenberg’s syndrome differ depending on the extent of the blockage.
Most common symptoms include:
- Vertigo and dizziness
- Nausea and vomiting
- Speech difficulties
- Ataxia – disordered movement
- Difficulty swallowing
- Numbness or tingling
