What is Epilepsy?

About Epilepsy:

  • Epilepsy — also known as a seizure disorder — is a chronic brain disorder where nerve cells don’t signal properly, that causes recurring seizures.
    • During a seizure,many neurons send signals at the same time, much faster than normal.
    • This surge of excessive electrical activity may cause involuntary movements, sensations, emotions, and/or behaviors.
    • The disturbance of normal nerve cell activity may cause a loss of awareness. 
    • Some people recover immediately after a seizure, while others may take minutes to hours to feel like themselves again.
  • Causes:
    • Epilepsy has many possible causes, but about half of people living with epilepsy do not know the cause.
    • In some cases, epilepsy is clearly linked to genetic factors, developmental brain abnormalities, infection, traumatic brain injury (TBI), stroke, brain tumors, or other identifiable problems. 
  • Seizure symptoms can vary widely:
    • Some people may lose awareness during a seizure while others don’t.
    • Some people stare blankly for a few seconds during a seizure.
    • Others may repeatedly twitch their arms or legs, movements known as convulsions.
  • Having a single seizure doesn’t mean you have epilepsy. Epilepsy is diagnosed if you’ve had at least two unprovoked seizures at least 24 hours apart.
  • Anyone can develop epilepsy. It affects both men and women of all races, ethnic backgrounds, and ages.
  • Around 50 million people worldwide have epilepsy, making it one of the most common neurological diseases globally.
  • Treatment:
    • Treatment with medicines or sometimes surgery can control seizures for most people with epilepsy.
    • Some people require lifelong treatment. For others, seizures go away.
    • Some children with epilepsy may outgrow the condition with age.
