Seizure

Seizure Overview

Abnormal electrical activity in the brain triggers seizure activity. A person may have a seizure disorder (epilepsy) and require medications. Other factors such as hypoglycemia (low blood sugar), which is a diabetic reaction, may cause seizures. Meningitis or a head injury may also cause a seizure.

Fainting can also cause a series of jerking movements as the person loses consciousness. These movements do not necessarily indicate a seizure.

Seizure Symptoms

  • Symptoms range from jerking movements in a single extremity to abnormal movements throughout the entire body.
  • Some seizures may cause lip smacking, behaviorisms, staring spells, or other symptoms depending on in which area of the brain the seizure cause originates.
  • Seizures may affect bladder and bowel control, and a person experiencing a seizure often bites his or her own tongue.
