Seizures triggered by blinking in a non-photosensitive epileptic.
نویسندگان
چکیده
An epileptic girl with Lennox-Gastaut syndrome had seizures triggered specifically by blinking, but not by other eye movements or by photic stimulation. Electrographic and clinical seizures were most reliably precipitated by repetitive blinking produced voluntarily on command, by reflex blinking on corneal stimulation, or by psychogenic triggers of blinking such as social stress or cognitive effort.

متن کاملTransition to seizure in photosensitive epilepsy
Photosensitive epilepsy (PSE) offers a highly reproducible model to investigate whether changes in neuronal activity preceding the transition to an epileptic photoparoxysmal response (PPR) may be detected. We investigated this possibility in patients with idiopathic PSE using MEG, as well as normal controls and non-photosensitive epileptic patients of the same age group. Spectral analysis of th...
متن کاملCortical triggers in generalized reflex seizures and epilepsies.
Activation of specific cortical territories by sensory stimuli or of less restricted areas of the brain by cognitive stimuli is known to induce apparently generalized seizures in predisposed patients; this is clinically and electroencephalographically distinct from reflex triggering of partial seizures. Photosensitive patients may have seizures when exposed to environmental stimuli producing ap...
