[Primary reading epilepsy. 11 cases].
Eleven cases of primary reading epilepsy are reported. They confirm Bickford's description. These patients were otherwise normal. A family history of seizures was present in 6 cases. The first seizure occurred between 12 and 25 years. After a variable period of reading all patients developed a tightness and jerking in throat and jaw muscles. In 4 cases, occasionally, speaking could cause jaw or throat jerks. Whilst reading out loud or silently (exclusively in reading aloud in 1 patient) bilateral discharges were recorded in EEG, sometimes on the left hemisphere. The mechanisms are discussed. Seizures in primary reading epilepsy are facilitated by saccadic eye movements, impulse language muscles and mental concentration. The role of higher integrating systems of language is emphasized. Therapy is discussed.
