Seizures triggered by blinking in a non-photosensitive epileptic

|April 1, 1986
Summary
Epileptic seizures in a girl with Lennox-Gastaut syndrome were specifically triggered by blinking. This included voluntary, reflex, and psychogenic blinking, but not other eye movements or flashing lights.
Area of Science:
- Neurology
- Epileptology
- Clinical Neuroscience
Background:
- Lennox-Gastaut syndrome is a severe form of epilepsy characterized by multiple seizure types.
- Identifying specific seizure triggers is crucial for effective management and treatment strategies.
Observation:
- A patient with Lennox-Gastaut syndrome experienced seizures exclusively triggered by blinking.
- Seizure precipitation was observed with voluntary blinking, reflex blinking (corneal stimulation), and psychogenic blinking (social stress, cognitive effort).
Findings:
- Blinking, a common and often involuntary action, was identified as a unique and potent trigger for both electrographic and clinical seizures in this case.
- Other eye movements and photic stimulation did not precipitate seizures, highlighting the specificity of the blinking trigger.
Implications:
- This case highlights the importance of considering even seemingly innocuous actions like blinking as potential seizure triggers in epilepsy.
- Further research into the neural mechanisms underlying reflex and psychogenic blinking-induced seizures may offer novel therapeutic targets for specific epilepsy syndromes.
