What Causes Epilepsy?


There are many different causes of Epilepsy. Your doctor will do a number of investigations to look for the cause. However, in 6 out of 10 children, no cause can be found.


The cause of Epilepsy when known can be classified into several broad categories.


  • Genetic: There is an underlying predisposition to having seizures. However, there is often no family history of seizures.
  • Structural: There is an underlying abnormality in the brain tissue that makes seizures more likely.
  • Metabolic: The cells in the brain use energy in a way that makes them more prone to creating abnormal electrical activity.
  • Unknown
