What is Brief Potentially Ictal Rhythmic Discharges and Paroxysmal Fast Activity as Scalp Electroencephalographic Biomarkers of Seizure Activity and Seizure Onset Zone about?
## Abstract ## Objective The electroencephalographic (EEG) terms “brief potentially ictal rhythmic discharges” (BIRDs) and “paroxysmal fast activity” (PFA) are considered distinct entities; however, their definitions overlap, and they may have similar clinical significance. We investigated their clinical significance and their association with seizures and the seizure onset zone (SOZ). ## Methods We retrospectively identified an adult cohort (July 2015 to March 2018) whose long‐term (>12 h) EEGs in any setting reported BIRDs (>4 Hz, lasting .5–10 s) and/or PFA. Different frequency cutoffs for PFA (>13 Hz or ≥8 Hz) were tested to compare their clinical significance. Patient demographics, clinical history, and EEG features were recorded. ## Results We identified 94 patients with BIRDs/PFA out of 3520 patients (3%); 36 were critically ill (12 with epilepsy), and 58 were noncritically ill (all with epilepsy). The frequency of BIRDs/PFA was largely dependent on EEG background: it tended to be slower (theta) in the absence of a posterior dominant rhythm or in the presence of continuous focal slowing in the same region (p = .01). Sixty‐two of 94 patients (66%; 32/36 [89%] critically ill,
