⩥ SREDA (subclinical rhythmic electrographic discharges of adults).
Answer: Sharply contoured theta activity in the posterior head region. A
normal variant in older adults during wakefullness.
⩥ 14 and 6 positive spikes. Answer: 1-2 seconds of sharply contoured
discharges in the posterior head regions in light sleep. Presents in
adolescents.
⩥ 6 hz spike and wave. Answer: Midparietal low amplitude discharges.
Occurs in young adults in drowsiness and disappears in sleep.
⩥ My rhythm. Answer: Oscillating 10 hz waves seen in leads overylying
the senserimotor cortex in the absence of movement. If a patient moves
or thinks about moving their contralateral limb, this rhythm will be
suppressed.
⩥ Wickets. Answer: Symmetric monophasic sharp wave occuring
predominantly in older adults during light sleep in temporal leads
without disruption of the background.
,⩥ 3 hz slow wave activity. Answer: 3 hz waves without an associated
spike which can be seen during hyperventilation in childhood
⩥ RTTBD (rhythmic temporal theta bursts of drowsiness). Answer: 5-6
hz rhythmic waves in the temporal lobe. Seen in young adults during
drowsiness.
⩥ Breach rhythm. Answer: Unilateral high voltage iregular wave
rhythms due to alteration of conductance commonly seen in patients
with a skull defect.
⩥ Anterior eye blinks (bells phenomenon). Answer: Positive downward
deflection, maximal in the frontopolar leads, followed by a negative
deflection from eye opening. Disappears in sleep.
⩥ EKG. Answer: Rhythmic electropositive discharges in one or multiple
leads, most often in the occipital leads. Time locked and synchronous
with the EKG tracing.
⩥ Pulse. Answer: Rhythmic slow waves in a single lead due to a close
pulsating vessel. Time locked but delayed after each QRS sample.
⩥ Lateral eye movements. Answer: Very slow out of phase derivations
involving anterior electrodes due to movement of the positively charged
, cornea. Best appreciated in drowsiness and early sleep when patient
experience rolling eye movements.
⩥ Muscle. Answer: Extremely high frequency waves often generated
from the frontalis and temporalis muscles. Usually spares central leads.
Disappears in sleep.
⩥ Glossokinetic. Answer: Diffuse, low frequency discharges produced
by movements of the negative tip of the tongue. Can be induced by
saying "la la la la", chewing, or sucking.
⩥ Electrode pop. Answer: Single or multiple sharp waves localized to a
single electrode without a surrounding field. Disappears by reapplying
an electrode.
⩥ GRDA (generalized rhythmic delta activity). Answer: Generalized in
all leads, typically signifies global cerebral dysfunction, such as in a
severe encephalopathy, but is not to be a risk factor for seizure or seizure
tendency.
⩥ Frontally dominant GRDA. Answer: Can be seen with a variety of
pathologies including posterior fossa lesions, intracranial lesions, and
increased intraventricular pressure.
