Definition and frequency of epilepsy

Show Summary Details

Preview

• Epilepsy is one of the most common neurological conditions. In a typical Western population of 1 million people, there will be 5,000 people with epilepsy and 500 new cases each year. • Epilepsy can take many forms and has many causes. • The highest incidence rates are in children and in the elderly. It also occurs with a high frequency in people with learning disability. • Although the prognosis is generally good, the mortality rate in epilepsy is higher than in the general population. Sudden unexpected death in epilepsy (SUDEP) is a particular problem occurring in patients prone to tonic-clonic seizures, at a frequency of approximately 1 case per 2,500 persons per year in mild epilepsy to 1 case per 100 persons per year in severe epilepsy.
