What Causes Seizures?

While it is difficult to pinpoint exactly what causes many seizures, a great deal has been learned about this condition. It is understood that a seizure occurs due to disruptions in the brain cells’ (neurons) electrical signals, causing a sudden electrical discharge in the brain that may affect an individual’s sensation, behavior, and/or consciousness. It is also understood that seizures may be partial (occurring in one or more regions of a single side of the brain) or generalized (occurring in both sides of the brain simultaneously).

Diagnosing what causes a specific patient’s seizures involves determining if the seizure is:

  • Unprovoked – Caused by phenomena occurring within the body such as:
  • Congenital defects
  • Genetic factors
  • An infection
  • Neurological problems
  • Chemical imbalances
  • Provoked – Caused by external factors such as:
  • Drug and/or alcohol use
  • Medications
  • Head trauma
  • Brain tumors
  • Stroke
  • Birth trauma
