Abstract
We define as early seizure (ES) those occurring within 7 days after stroke and late seizures those developing beyond 1 week after stroke. Seizures are well known to occur at the onset of intracerebral hemorrhage and serve as a clinical marker. Onset seizures may be focal or generalized, are usually brief, and are associated with loss of consciousness in the setting of hemorrhage. A similar concept of immediate seizure occurs in traumatic brain injury. Predictive factors of ES can be classified of general and neurologic origin. An important question is whether ES per se worsen prognosis and outcome. The viability of the penumbral region in animal models of focal ischemia is influenced by the peri-infarct depolarization waves. If this also is true in humans, seizures in the immediate poststroke period might worsen outcome. Recently, hypercholesterolemia has been associated with better functional outcome at 1 month after a first-ever stroke, and multivariate analysis studies have shown that mean cholesterol values were lower in patients with ES compared with controls.
