What Causes Seizures?

Seizures can be caused by many things. These include:

  • Unbalanced signalling of nerve cells (neurons) in your brain
  • Brain tumor
  • Stroke
  • Brain damage from illness or injury
  • Genetic conditions

Epilepsy may be caused by a combination of these things. In many of those with epilepsy, the cause of epilepsy that leads to seizures is unknown.

Globally, 50% of those with epilepsy have an unknown cause of seizures.
