Due to depression and brain damage, people sometimes develop abnormal sleep patterns after strokes, and the ensuing sleep deprivation exacerbates the possibility of seizures, according to About.com. Stroke survivors should remain moderate in alcohol consumption to lessen the risk of seizures. Doctors prescribe anti-seizure medication to stroke victims, but if they forget to take it or skip doses because of the side effects, they increase their risk of seizures. The anti-seizure medications may also react negatively with other medications the patient is taking, and doctors may periodically need to adjust dosages. If stroke survivors develop new onset epilepsy, they may sometimes need to change or add anti-seizure medications.

To help prevent seizures, stroke survivors should participate in regular exercise and avoid overexertion, dehydration and hypoglycemia, as advised by the National Stroke Association. Because of the risk of seizures, driving may prove difficult for stroke survivors, and people should supervise them when they perform other potentially dangerous activities, such as swimming and cooking. Stroke survivors should also educate family, friends and colleagues about what to do if they have a seizure.
