Paroxysmal, rhythmic lingual movements and chronic epilepsy
Neurology
|October 1, 1981
Summary
Three children experienced rhythmic tongue movements during sleep, linked to unusual subcortical seizures. These paroxysmal lingual movements were confirmed via electroencephalogram during a chronic epilepsy study.
Area of Science:
- Neurology
- Epileptology
- Pediatric Neurology
Background:
- Investigating oropharyngeal muscle movements in chronic epilepsy patients.
- Focus on identifying epileptiform activity during sleep.
Observation:
- Observed paroxysmal and rhythmic lingual movements in three pediatric patients.
- Movements were isolated to the tongue and primarily occurred during sleep.
- Recurrence noted in two children over 18 months.
Findings:
- Tongue movements correlated with episodic electroencephalogram desynchronization.
- Attributed movements to a novel form of subcortical seizures.
- Distinct from typical generalized or focal epileptic seizures.
Implications:
- Suggests subcortical seizures can manifest as isolated lingual movements.
- Highlights the need for detailed observation of oropharyngeal activity in epilepsy diagnosis.
- Potential for new diagnostic markers in pediatric epilepsy.
