What is Epilepsy?
1 in 26 Americans will develop epilepsy in their lifetime
Epilepsy is a diverse group of neurological disorders of varying types and severities which are characterized by recurrent seizures. (Epilepsy is sometimes called “seizure disorder.”) When a person has had two or more seizures which have not been provoked by specific events such as trauma, infection, fever or chemical change, they are considered to have epilepsy.
In general, epilepsy and seizures result from abnormal circuit activity in the brain. Any event ranging from faulty wiring during brain development, brain inflammation, physical injury or infection can lead to seizure and epilepsy. Underlying causes for epilepsy include:
However, according to recent estimates, in up to 50% of patients diagnosed with epilepsy, the cause is unknown (idiopathic).
Epilepsy and seizures can develop in any person and at any age, though new cases are most common in children, especially in the first year of life. An estimated 65 million people worldwide currently live with epilepsy, including more than 3.4 million Americans. In fact, one in 26 Americans will develop epilepsy in their lifetime.
Sadly, there is no cure for epilepsy. There are, however, many treatments and therapies available to help patients with epilepsy become seizure-free, including medication, anti-seizure devices, and surgery.
While a majority of patients with epilepsy will achieve seizure freedom, more than 30% do not respond to medication at all, and their seizures remain uncontrolled. Research will help us find a cure for epilepsy.
Globally, the burden of epilepsy is huge: Of the top 5 chronic conditions among children and adults, epilepsy is the costliest and second most common. Epilepsy costs the United States approximately $15.5 billion each year, yet U.S. federal funding in epilepsy is modest and lags behind other common neurological conditions.
Epilepsy can be diagnosed by administering tests to assess whether there are any detectable abnormalities in a person’s brainwaves; the most common diagnostic test for epilepsy is the electroencephalogram (EEG). Tests can determine if a person has epilepsy and, if so, what kind of seizures will result.
Epilepsy and seizures can be treated by a variety of therapies, including medication, dietary changes, and surgery. Some individuals with treatment-resistant epilepsy also explore alternative treatments while looking to achieve seizure freedom, including participating in clinical drug trials.
