Pseudointerictal
Pronunciation: /ˌsuːdoʊɪntərˈɪktəl/
EEG patterns that appear abnormal between seizures but are not truly epileptiform in nature.
Full Definition
Pseudointerictal refers to EEG abnormalities that occur between seizures but do not represent genuine epileptiform activity. These patterns may include benign variants, artifact, or non-specific abnormalities that can be mistaken for interictal epileptiform discharges by inexperienced readers. Common pseudointerictal patterns include wicket spikes, 6-Hz phantom spike-and-wave, small sharp spikes, and 14-6 Hz positive spikes. Proper identification of these patterns is crucial to avoid misdiagnosis and inappropriate treatment of non-epileptic conditions.
Usage
