Only a minority of epilepsy cases have clear causes. The most common causes of epilepsy are associated with trauma or injury to the brain. These include brain damage at birth or from accidents during adolescence, brain tumours, brain infections such as meningitis and encephalitis, Scarring or “sclerosis” of brain tissue, and strokes. In addition, a strong family history of epilepsy increases the susceptibility to the disease.
Certain factors can also trigger seizures in people with epilepsy. These include forgetting to take seizure medications, heavy alcohol consumption, drug abuse (including Cocaine, Ecstasy), sleep deprivation (insomnia) and use of drugs that interfere with seizure medications.
