interictal
Pronunciation: in-ter-IK-tal
Relating to the period between seizures in patients with epilepsy.
Full Definition
Interictal refers to the time intervals between epileptic seizures when the patient appears clinically normal but may still show abnormal brain activity on EEG. During interictal periods, patients may experience subclinical epileptiform discharges that can affect cognitive function, mood, and behavior. This concept is crucial in neuropsychiatry as interictal psychiatric symptoms are common in epilepsy patients and may require specific management approaches.
