Seizures are changes in the brain’s electrical activity. Depending on the severity of the change and location in the brain, the symptoms of a seizure can be dramatic, barely noticeable or have no symptoms at all. There are many different types of seizures, but the two major types are called focal onset seizures and generalized onset seizures.

Focal onset seizures: A seizure focused on a single area of the brain. The person may be aware they are having a seizure or they may lose consciousness. 

Generalized onset seizures: Seizures that start on both sides of the brain at the same time. 

Seizure Symptoms

The symptoms of a seizure can last anywhere from a few seconds to several minutes. Signs that a seizure is about to happen include:

  • Sudden feeling of fear
  • Nausea
  • Dizziness
  • Change of vision
  • Out of body sensation
  • Headache 

Symptoms of a seizure in progress include:

  • Loss of consciousness
  • Uncontrollable muscle spasms
  • Drooling at the mouth
  • Clenching teeth
  • Sudden, rapid eye movements

Seizure Causes

Seizures may be the result of a variety of health conditions. A person may have a single seizure in their life or suffer from a condition called epilepsy where they are prone to random seizures. Other causes of seizures include:

  • Brain infection
  • Drug withdrawal
  • Electrical shock
  • High blood pressure
  • Head trauma
  • Drug abuse
  • Stroke
  • Brain tumor
