  • Shuddering episodes are characterized by periods of rapid tremor of the head, shoulders and arms that resemble shivering. It is often accompanied by facial grimacing with preserved consciousness
  • Onset is in infancy or early childhood, but can occur as late as 10 years of age
  • The episodes last several seconds and can occur up to 100 times a day.
  • Spells are often triggered by excitement, frustration, embarrassment, or surprise
  • The differential diagnosis of shuddering attacks includes benign neonatal sleep myoclonus, jitteriness, epilepsy, benign myoclonus of infancy, and tremor.
  • The preservation of consciousness, predictable triggers, ability to abort an episode when distracted by a parent, and normal EEG distinguish this entity from seizures.
  • The prognosis for development and neurologic function is uniformly good.
  • Treatment is generally not needed
