A state of disorientation and cognitive impairment that occurs immediately following a seizure.
Full Definition
Postictal confusion is a transient state of altered consciousness characterized by disorientation, memory impairment, and reduced cognitive functioning that follows an epileptic seizure. The duration and severity vary depending on seizure type, location, and individual factors, typically lasting minutes to hours. This period is important for differential diagnosis as it helps distinguish epileptic seizures from other paroxysmal events such as syncope or psychogenic non-epileptic seizures.
Usage
Usage note: Hyphenate when used as a compound adjective before a noun.
