ictal

Full Definition

The term 'ictal' describes phenomena that occur during an actual seizure event, as opposed to interictal (between seizures) or postictal (after seizures) periods. Ictal symptoms include the seizure manifestations themselves, such as motor movements, altered consciousness, sensory changes, or behavioral automatisms. In neuropsychiatric practice, ictal psychiatric symptoms can include fear, euphoria, hallucinations, or complex behaviors that may be mistaken for primary psychiatric disorders. Accurate identification of ictal versus non-ictal symptoms is crucial for proper diagnosis and treatment.
