Epilepsy with reading-induced seizures

Epilepsy with reading-induced seizures, also known as reading epilepsy or primary reading epilepsy, is a rare form of reflex epilepsy in which seizures are specifically triggered by the act of reading. It is classified among the idiopathic generalized epilepsies and primarily affects the central nervous system. The condition was first described by Bickford in 1956 and is considered a distinct epilepsy syndrome. The hallmark feature of this condition is the occurrence of seizures provoked by reading, particularly prolonged or silent reading. The initial symptoms typically involve brief myoclonic jerks affecting the jaw, tongue, lips, and facial muscles (orofacial or perioral myoclonus), which patients often describe as a clicking or locking sensation in the jaw while reading. If the individual continues to read despite these warning signs, the myoclonic jerks may progress to generalized tonic-clonic seizures. Some patients may also experience visual symptoms or alexia (difficulty reading) as part of the seizure. The seizures are thought to involve complex cortical processes related to language, including visual processing, phonological decoding, and articulation. The typical age of onset is during adolescence or early adulthood, most commonly in the second decade of life. Males appear to be more frequently affected than females. A family history of epilepsy is reported in a significant proportion of cases, suggesting a genetic predisposition, though the exact genetic basis remains incompletely understood. Electroencephalography (EEG) during reading may show bilateral spike-wave or polyspike-wave discharges, often with left hemisphere predominance. Treatment primarily involves avoidance of prolonged reading when possible and antiepileptic medications. Valproic acid (sodium valproate) is generally considered the first-line treatment and is effective in most patients. Levetiracetam and clonazepam have also been used with success. The prognosis is generally favorable with appropriate management.
