According to the National Institute of Neurological Disorders and Stroke, Wallenberg Syndrome (aka Lateral Medullary Syndrome) is a neurological condition caused by compromise of the vertebral artery (VA) or posterior inferior cerebellar artery (PICA), ultimately leading to infarction of the lateral medulla.

Epidemiology/Etiology/Prognosis[edit | edit source]
A study reviewing 25 cases of Wallenberg Syndrome found the incidence to be highest in middle-aged men at 55.06 years of age (Srivastava et al., 2015). The greatest risk factor for Wallenberg Syndrome is currently believed to be atherosclerosis, which is often linked to a history of hypertension, diabetes, and smoking (Gregory et al., 2014). The long-term outlook varies quite substantially, with some individuals seeing a decrease in symptoms within weeks, whereas others may have symptoms persist for years (Srivastava et al., 2015). With appropriate treatment, clinical monitoring, and post-stroke care, the prognosis for recovery remains positive. Majority of patients have minimal deficits at six months, and over 85% have been found to attain functional independence with ambulation within a year (Gregory et at., 2014). Overall, researchers have yet to confidently determine why this type of stroke occurs.
