Question 1: Rhythmic Temporal Theta Bursts of Drowsiness (RTTD)

Answer:

Recorded mostly in adolescents & young adults during relaxed wakefulness & drowsiness. Present predominantly over the posterior head regions & usually is maximal over the midtemporal regions. The discharge may have a notched or flat-topped appearance.

Question 2: 14- and 6-Hz Positive Bursts

Answer:

Seen in children & adolescents during drowsiness & light non-REM sleep. These rhythmic bursts consist of trains of arch shaped waves & occur bisynchronously or independently. The bursts are usually maximal voltage over the posterior temporal head region.Question 3: Small Sharp Spikes (SSS)/Benign Epileptiform Transients of Sleep (BETS)

Answer:

Recorded mainly in adults during drowsiness & light non-rapid eye movement sleep. Typically low voltage and are short duration. Morphologically, the discharges are monophasic/diphasic spikes, at times followed by a low-voltage slow wave component.

Question 4: Breach Rhythms

Answer:

Present over skull defects. Higher in amplitude and may have a sharp appearance.

Question 5: 6-Hz Spike and Wave/Phantom Spike and Wave

Answer:

Typically has a very low voltage, fast frequency spike discharge followed by a more prominent slow-wave component usually of higher amplitude. Most common in adolescents & young adults during relaxed wakefulness & drowsiness, with disappearance in deeper

Question 6: Midline Theta Rhythms

Answer:

Consists of trains of rhythmic 5-7 Hz activity recorded over midline electrodes. Recorded during awake and drowsy states in both children and adults and may have a smooth, sinusoidal, arciform, spikey, or mu like appearance.

Question 7: Wicket Spikes

Answer:

Best appreciated during drowsiness & light sleep. Likely present when background contains sharply contoured waveforms (6-11 Hz) & are usually recorded over the anterior or mid-temporal head regions.

Question 8: Subclinical Rhythmic Electrographic Discharge in Adults (SREDA)

Answer:

Occurs in w/hyperventilation in adults over the age of fifty. Also present during drowsiness & rest.Consists of rhythmic, sharply contoured waveforms that evolve into a sustained 5 to 6 Hz pattern.Widespread & maximal over the parietal & posterior tempo
