Absence seizures are a form of epilepsy. They mainly occur in children and young people. Absence seizures are a brief loss of consciousness (an 'absence') for a few seconds, and can appear like daydreaming. Although no underlying cause for this type of seizure can be found, it is thought that the brain develops a low threshold for bursts of abnormal electrical activity. Ethosuximide is one of the medicines commonly prescribed for this type of epilepsy. It helps to reduce absence seizures by stabilising the abnormal electrical activity in the brain.
