wicket rhythm
A benign EEG pattern resembling mu rhythm but occurring in temporal regions, often mistaken for epileptiform activity by inexperienced interpreters.
Full Definition
Wicket rhythm is a normal EEG variant characterized by arcuate or wicket-shaped waveforms in the temporal regions, typically occurring at 6-11 Hz. Named for its resemblance to cricket wickets, this pattern can be asymmetric and may appear sharp, leading to misinterpretation as temporal lobe epileptiform discharges. It is most commonly seen in adults and elderly patients during drowsiness or light sleep. Recognition of wicket rhythm is crucial for editors reviewing neurological reports, as misidentification can lead to unnecessary antiepileptic drug prescriptions and patient anxiety.
Usage
Usage note: Always lowercase when referring to the EEG pattern; capitalize only when beginning a sentence.
