Corticosteroids are commonly used in the treatment of stroke, although their clinical effectiveness has not been established. Side effects, especially gastrointestinal complications, occur in patients with cerebral disease. A necroscopy study of 124 patients investigated the occurrence of gastrointestinal lesions in patients with acute stroke treated with high-dose of corticosteroids compared to untreated patients with stroke and to patients dying from non-vascular neurological diseases. A significant relationship between the use of steroids and gastrointestinal lesion in strokes is demonstrated.
