Cerebellar Ischemic Stroke
Ischemic damage, regardless of cause, results in endothelial cell damage predisposing to thrombosis, necrosis, and hemorrhage. One of the most devastating effects of severe intracranial vascular disease is intracranial hemorrhage. Hemorrhage into and around the brain can result in an associated inflammatory reaction, increases in overall intracranial volume, and increases in intracranial pressure. If bleeding is substantial, hematomas may subsequently form.
Age of Onset: 8-9 years of age
Sex Predisposition: Any sex of animal can be affected
Clinical Course:
Clinical signs may stabilize within the first 48 hours or progress rapidly. Most dogs will improve over the course of 1-10 days.
Dogs may have a history of previous episodes that resolved rapidly, suggestive of a more transient ischemic event.
