Reading and language-induced epilepsy

Primary reading epilepsy
Primary reading epilepsy usually begins when the person is between 12 and 25 years old. In this condition, seizures are provoked only by reading, and people do not have seizures at other times. Usually, while reading, the person’s jaw clicks or jerks and, if she keeps reading, she may have a generalized tonic-clonic seizure. Other seizure types may also occur. People with this syndrome often have a family history of epilepsy, and cases of reading epilepsy that run in families have been reported. Primary reading epilepsy may be a specific form of language-induced epilepsy (see below).

Secondary reading epilepsy
Secondary reading epilepsy is very similar to primary reading epilepsy, except that people with this condition may also have unprovoked seizures.

Language-induced epilepsy
In language-induced epilepsy, stimuli such as writing, typing, listening to speech, singing, or reciting may trigger seizures. People with this syndrome have jaw jerks with abnormal EEG activity.

Some symptomatic epilepsies may also result in reading- or language-induced seizures.
