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 ...

RMTD (rhythmic midtemporal theta burst of drowsiness) Synonymes: Rhythmic midtemporal discharges, RTTD, psychomotor variant pattern. Does not change in frequency or form, in contrast to an epileptic discharge. RMTD: Rhythmic theta waves right temporal (average) This page was last modified on 14 March 2017, at 11:36.

Herein, we illustrate two pediatric cases with bursts of rhythmic mid-temporal theta of drowsiness (RMTD), activated by hyperventilation. Continued awareness of this EEG phenomenology and its variations in pediatrics is important in avoiding misdiagnosis of epilepsy.

2024年8月1日 · Wicket waves, 6 Hz spike and slow wave, 14 and 6 Hz positive bursts, and Rhythmic Temporal Theta of Drowsiness (RTTD) were identified in 67 (2.2%), 40 (1.3%), 39 (1.3%), and 35 (1.16%) patients, respectively and one patient with Subclinical Rhythmic EEG Discharges in Adults (SREDA).

2019年3月2日 · In this chapter we discuss spiky normal variants including breach rhythm, benign epileptiform transients of sleep (BETS), 14 & 6 positive spikes, 6 Hz (phantom) spike and wave, wicket spikes, and rhythmic normal variants including rhythmic temporal theta of drowsiness (RTTD) and subclinical rhythmic electrographic discharge of adults (SREDA).

2020年8月1日 · Our findings show that scalp EEG correlates of hippocampal ictal discharges can resemble RTTBD and may be associated with ictal symptoms and cognitive impairment, indicating that RTTBD may rarely be an ictal EEG pattern in patients with TLE.

2021年5月18日 · Rett syndrome (RTT) is a rare neurodevelopmental disorder that is usually caused by mutations of the MECP2 gene. Patients with RTT suffer from severe deficits in motor, perceptual and cognitive domains. Electroencephalogram (EEG) has provided useful information to clinicians and scientists, f …

2012年4月13日 · Rhythmic temporal theta bursts of drowsiness (RTTD), also known as “psychomotor variant”, and subclinical rhythmic EEG discharge of adults (SREDA) are two EEG patterns of uncertain significance that occur without any correlation with epilepsy.

Rhythmic temporal theta of drowsiness. Bitemporal left greater than right, longitudinal bipolar montage. Noted are notched rhythmic waveforms localized to the temporal regions, some of which are sharply contoured.
