Symptoms of a Brain Seizure

The brain communicates through electrical signals. However, when there is abnormal electrical activity, a seizure can happen. The type of seizure and the resulting symptoms you may have depend on the region of the brain where it is located. Because the symptoms of a brain seizure can range from barely noticeable to losing control and falling, it is important to know how to lower your risk of seizures occurring and how to protect yourself during a seizure.

  1. Causes

    • Seizures can be caused by a variety of factors. Among them are an injury to the brain because of brain tumors, brain lesions, degenerative brain diseases, congenital brain defects, brain abscess, meningitis, encephalitis, neurosyphilis, traumatic brain injury or a stroke. Alcoholics who drink heavily often, then suddenly cease drinking, are also at risk for having a seizure. In addition, having abnormal levels of sodium or glucose, either too much or too little, can result in a seizure. The abnormal levels can be caused by kidney or liver failure.

    Symptoms

    • Symptoms for a brain seizure depend on the brain lobe in which the seizure is localized. The most common symptoms are loss of muscle control, falling suddenly, twitching and tension in the muscles. Other symptoms include changes in consciousness, emotion, sensation and vision. However, some people may not even notice they are having a seizure if their symptoms are lighter; these symptoms include staring off for a few minutes--an example of a change in consciousness. One indicator of an on-coming seizure is tasting a bitter or metallic flavor.

    Timeline

    • Most seizures last a few minutes, rarely going beyond 15 minutes. Seizures come on suddenly and sometimes without warning. For people whose symptoms include full body shaking, it should cease within 5 minutes.

    Seeking Medical Help

    • If you have a seizure for the first time, call 911. Since seizures can be caused by serious ailments, it is important to be examined. In addition, if the seizure incident lasts longer than usual, medical attention should be sought immediately.

    Prevention

    • There is no way to prevent an unprovoked seizure. Staying healthy and avoiding illegal substances can lower your risk for a seizure. If you are prone to seizures, wearing a helmet can prevent head injuries and brain trauma. In addition, you should not drive if you have frequent seizures.
