Eclampsia, high fevers in children, psychological problems and migraines can cause seizures that are not related to epilepsy, notes WebMD. Some people experience first seizures, which may be brought on by drugs or anesthesia but often occur with no trigger. Unless the person suffers brain damage during a first seizure or has a family history of epilepsy, these seizures usually do not recur.
Eclampsia is a condition that causes seizures in pregnant women accompanied by an abrupt rise in blood pressure, states WebMD. Women who receive treatment for eclampsia and give birth generally do not suffer from additional seizures. Children who have high fevers may suffer from febrile seizures, with a 25 to 30 percent chance of recurrence, though they generally do not develop epilepsy. Children with family histories of epilepsy or nervous system damage that occurred before the seizure or who had prolonged or complicated seizures are at higher risk of recurrence.
People with psychological problems may experience non-epileptic events that have the same symptoms as seizures but are not accompanied by the abnormal electrical discharges in the brain that typify epileptic seizures, according to WebMD. These types of events are called psychogenic seizures, and doctors typically refer patients with these seizures to mental health professionals.
