interictal state
Pronunciation: /ˌɪntərˈɪktəl/
The period between epileptic seizures when patients appear neurologically normal, crucial for baseline neuroimaging comparisons.
Full Definition
The interictal state represents the baseline neurological condition of epilepsy patients between seizure episodes, characterized by the absence of overt clinical seizure activity. This state is fundamental in neuroimaging research as it provides the reference condition against which ictal (during seizure) and postictal (after seizure) changes are compared. Interictal neuroimaging studies help identify structural abnormalities, metabolic changes, and functional network alterations that may contribute to seizure generation. Editors reviewing epilepsy neuroimaging literature must understand this terminology to accurately assess study designs and interpret findings related to seizure localization and characterization.
Usage
Usage note: Always hyphenate when used as a compound modifier (e.g., 'interictal-state imaging').
