The range of benign variants includes wicket waves, rhythmic mid-temporal theta of drowsiness (RMTD or RTTD), benign small sharp spikes (BSSS, sometimes denoted BSST for benign small sleep transients), 14 and 6 positive spikes, 6-Hz “phantom” spike and wave, subclinical rhythmic EEG discharge of adults (SREDA), and the midline theta rhythm ...

Benign epileptiform transients of sleep (BETS) are also called small sharp spikes (SSS). While BETS have a slightly oxymoronic name, they are in fact a normal, benign finding that you can …

2020年12月1日 · SSS can be an epileptiform EEG pattern for temporal lobe epilepsy. 1. Introduction. Small sharp spikes (SSS) are defined as electronegative spikes in the temporal region with duration < 50 ms and amplitude < 50μv, appearing almost exclusively during drowsiness and light sleep.

2021年6月1日 · To study the prevalence of benign EEG variants (BEVs) in the sleep–wake cycle among 1163 consecutive patients. Prospective, observational EEG study using the 10–20 system with systematically two additional anterior-temporal electrodes. Depending on clinical indications, other electrodes were added.

2024年8月1日 · The analysis of EEG demands expertise and keen observation to distinguish epileptiform discharges from benign epileptiform variants (BEVs), a frequent source of erroneous interpretation. The prevalence of BEVs varies based on …

BSSS (aka BETS) on ipsilateral ear reference (left) and longitudinal bipolar montage (right). Note steep descending slope of low-amplitude spike and small after-coming slow wave, particularly at T7 to TP11. BSSS are a common feature in adult EEGs during drowsiness and sleep.

2024年10月15日 · BSSS are among the most common benign EEG variants, appearing in 1.85% to 24% of scalp EEG recordings. [3] BSSS are usually observed in adults and seldom in children.

Results: We identified 296 patients with BEVs after reviewing 3000 EEGs (9.9%). The most common BEV was small sharp spikes (SSS), observed in 114 patients (3.8%).

2022年9月2日 · Benign sporadic sleep spikes (BSSS), also referred to as small sharp spikes or benign epileptiform transient of sleep (BETS), are low amplitude (<50 mV), brief (<50 ms), sharply contoured monophasic or biphasic electronegative spikes …
