Abstract:
Cerebellar strokes account for less than 10% of all strokes but lead to significantly poor outcomes. Cerebellar strokes that are initially missed have a mortality rate of 40%, and half of the patients who survive have long-term deficits. The patient's history may provide clues that point to a cerebellar stroke. Signs and symptoms include vertigo, headache, vomiting and ataxia. It is important to note the presence of stroke risk factors, such as a history of strokes or transient ischemic attacks, diabetes mellitus, hypertension, hypercholesterolemia, advanced age, atrial fibrillation, and cigarette smoking. The importance of early and correct diagnosis is imperative to reduce morbidity and mortality.
