Summary

Rhythmic teeth grinding can be a symptom of temporal lobe epilepsy, not just sleep bruxism. This study highlights motor events during seizures, differentiating them from sleep disorders.

Area of Science:

  • Neurology
  • Sleep Medicine
  • Epileptology

Background:

  • Teeth grinding, or bruxism, is often associated with sleep disorders.
  • Temporal lobe epilepsy is a neurological condition affecting brain activity.

Observation:

  • A patient presented with rhythmic teeth grinding as the primary symptom of temporal lobe seizures.
  • The teeth grinding occurred during both sleep and wakefulness.

Findings:

  • Polygraphic and clinical data confirmed the teeth grinding was linked to epileptic seizures.
  • Electromyographic and autonomic features indicated a specific form of masticatory activity during seizures.

Implications:

  • This finding expands the understanding of seizure manifestations beyond typical motor symptoms.

  • It suggests that teeth grinding can be an epileptic motor event, distinct from sleep bruxism.
  • Clinicians should consider epilepsy in the differential diagnosis of unexplained rhythmic teeth grinding.
