Todd's paralysis
A temporary weakness or paralysis in a portion of the body following a focal seizure, typically lasting minutes to hours.
Full Definition
Todd's paralysis, also known as postictal paralysis, is a focal neurological deficit that occurs after a seizure, most commonly following focal motor seizures. The weakness typically affects the body parts involved in the seizure and can range from mild weakness to complete paralysis. It usually resolves within 24-48 hours but can occasionally persist longer. The phenomenon helps localize the seizure focus and should be distinguished from stroke or other acute neurological conditions.
Usage
Usage note: Possessive form with apostrophe. Named after Robert Bentley Todd. Distinguish from other acute weakness causes.
