What Is a Seizure Disorder?
The term
seizure disorder refers to a disorder that occurs when clusters of nerve cells, or neurons, in the brain sometimes signal abnormally. When these brain cells are not working properly, a person's consciousness, movement, or actions may be altered for a short time. These physical changes are called epileptic
seizures.
Seizure disorders are more commonly known as
epilepsy and affect people of all nationalities and races.
What Causes a Seizure Disorder?
A seizure disorder can be caused by a variety of factors. Anything that disturbs the normal pattern of neuron activity -- from illness to brain damage to abnormal brain development -- can cause a seizure. A seizure disorder may develop as the result of abnormality in brain wiring, an imbalance of nerve signaling chemicals called neurotransmitters, or some combination of these factors.
Seizure disorders are not contagious and are not caused by mental illness or mental retardation.
Diagnosing a Seizure Disorder
Experiencing a single seizure does not necessarily mean that a person has a seizure disorder. Only when a person has had two or more seizures is he or she considered to have a seizure disorder. Brain scans and electroencephalograms (EEGs) are common tests used to diagnose a seizure disorder.
Treatment for a Seizure Disorder
After a person has been diagnosed with a seizure disorder, seizures can be controlled with modern medicines and surgical techniques. In 1997, the Food and Drug Administration (FDA) approved the
vagus nerve stimulator for use in people with seizures that are not well-controlled by medication.
