Seven questions about stroke and epilepsy.

Seizures and stroke are both common neurologic conditions, but when they occur in close temporal proximity they produce much more concern than either does alone. The stroke specialist (and the family) fear that convulsions will worsen the stroke because of acute hypertension and airway compromise, and the epileptologist is concerned that these acute seizures are the harbingers of later epilepsy. Other less commonly recognized but important aspects of this relationship are that subclinical seizures worsen some forms of stroke, and some anticonvulsants may have more adverse effects on stroke patients than they do in other groups. In surveying the connections between these two conditions, I have attempted to address seven questions. For some questions, there are data to help provide an answer; for others, there is only opinion; and for a maddening few, newer research is making older suggestions less certain.
