What Is Wallenberg Syndrome?
2. Causes of Wallenberg Syndrome
It is not clear why Wallenberg syndrome occurs. However, the condition develops when the brain stem is starved of oxygen for a period of time. This leads to inflammation of the affected brain cells making them ineffective in carrying out their functions.
When this happens, the body functions controlled from the affected part of the brain can no longer run normally. This is what leads to the symptoms described above.
The cells that make up the brain stem, as indeed the rest of the brain and the body, need oxygen and nutrients to produce energy. These are delivered through blood. If, however, blood rich in oxygen and nutrients does not flow with ease to these cells, they can no longer produce the energy necessary for them to function. If this continues for some time, the cells may even die, making the brain tissue dysfunctional.
