Todd's paralysis is a neurological condition characterized by a brief period of transient (temporary) paralysis following a seizure. The paralysis - which may be partial or complete - generally occurs on one side of the body and usually subsides completely within 48 hours. Todd's paralysis may also affect speech or vision. The cause is not known. Examination of an individual who is experiencing or who has just experienced Todd's paralysis may help physicians identify the origin of the seizure. It is important to distinguish the condition from a stroke, which requires different treatment.

Treatment of Todd's paralysis is symptomatic and supportive because the paralysis disappears quickly.

An occurrence of Todd's paralysis indicates that a seizure has occurred. The prognosis for the patient depends upon the effects of the seizure, not the occurrence of the paralysis.
