The patient is considered to have sleep-type epilepsy when he or she convulses in his or her sleep in the middle of the night. Sleep-type epilepsy is a type of epilepsy that can be identified by giving the patient an EEG, if necessary, or a 24-hour EEG or video EEG. There is a direct correlation between the type of seizure and the cause and prognosis of sleep-onset epilepsy. In the case of young children or adolescents with nocturnal sleep-onset epilepsy, the seizures can resolve spontaneously as they grow older, after puberty. If sleep-type epilepsy occurs in middle-aged or elderly people, head CT or magnetic resonance imaging (MRI) should be performed to rule out the possibility of secondary epilepsy. If necessary, the patient should be given medication to control seizures, which may include clonazepam or diazepam.
