Partial Parietal Seizure Disorder

A seizure disorder, also referred to as epilepsy, is a brain disorder in which the nerve cells in the brain become overly stimulated and fire at a rapid rate. This rapid, abnormal firing of neurons may begin in one part of the brain, but it usually spreads to adjacent areas.

Causes

• A seizure disorder can be caused by genetic abnormalities, brain trauma, alcoholism, Alzheimer's disease, imbalances in the levels of brain chemicals called neurotransmitters or exposure to lead or toxins. It can occur after strokes or other brain injuries.

Prevalence

• About one in every 100 people has had a seizure or has been diagnosed with a seizure disorder.

Types

• Partial seizures may affect one region of the brain and are named after the area where they originate. Generalized seizures may start in one area of the brain but rapidly spread to other areas. These types of seizures often result in a loss of consciousness.

Effects

• Partial parietal seizures -- named for the brain's parietal lobe, where they begin -- create sensations of tingling and feelings of electricity or discomfort. Usually the seizure affects other regions of the brain.

Treatment

• Anti-seizure medications can slow or prevent seizures. Partial parietal seizures that do not respond to medication may sometimes be treated surgically.
