Todd's paralysis

From WikiMD

Todd's paralysis is a neurological condition experienced by individuals with epilepsy, in which a seizure is followed by a brief period of temporary paralysis.

Pathophysiology

  • The paralysis may be partial or complete but usually occurs on just one side of the body.
  • The paralysis can last from half an hour to 36 hours, with an average of 15 hours, at which point it resolves completely.
  • Todd's paralysis may also affect speech and vision.

Cause

  • What causes Todd's paralysis is not known.
  • Current theories propose biological processes in the brain that involve a slow down in either the energy output of neurons or in the motor centers of the brain.

Differential diagnosis

  • It is important to distinguish Todd's paralysis from a stroke, which it can resemble, because a stroke requires completely different treatment.

Prognosis

  • Todd's paralysis is an indication that an individual has had an epileptic seizure.
  • The outcome depends on the effects of the seizure and the subsequent treatment of the epilepsy.

Treatment

  • There is no treatment for Todd's paralysis.
  • Individuals must rest as comfortably as possible until the paralysis disappears.
