Definition
- Adjective:
- Relating to or characteristic of a seizure: Describes something that pertains to, occurs during, or is associated with a sudden, abnormal electrical discharge in the brain, often manifesting as convulsions or other physical symptoms.
Usage
- The term "ictal" is primarily used in medical and clinical contexts, particularly in neurology and epileptology, to describe events, states, or phenomena directly linked to an active seizure.
- It is often used in contrast with "interictal" (between seizures) and "postictal" (after a seizure).
Examples
- Adjective:
- The patient's ictal activity was recorded on the electroencephalogram (EEG).

- An ictal cry sometimes occurs at the onset of a tonic-clonic seizure.
Advanced Usage
- "Ictal event": A specific occurrence or manifestation of a seizure.
- The sudden loss of awareness was identified as an ictal event.
- "Ictal period": The duration during which a seizure is actively occurring.
- The ictal period for this type of seizure typically lasts 30 to 90 seconds.
