EEG BOARD CERTIFICATION
EVALUATION EXAMS COMPLETE
QUESTIONS AND ANSWERS
◉ Beta. Answer: ->14 HZ
-detected during wakefulness, enhanced during drowsiness, and decreased in deeper sleep
-seen on barbiturates and benzodiazepines
◉ Lambda waves. Answer: -NORMAL, awake
-sharp waves occurring in occipital region (o1/o2) during wakefulness
-visually scanning a picture in a lit room
-physiological, eyes OPEN
-saccadic eye movement
-4-6hz
◉ Small sharp spikes / BETS. Answer: -occurs in stage 1/stage 2
-peaks at 30-60 years
-temporal region
-occurs sporadically and short duration
-NORMAL benign variant
◉ Wicket Spikes. Answer: -Single spike or 6-11 hz Mu like shape seen in drowsiness and light sleep.
-mid temporal region
-seen in adults over 30
-NORMAL benign variant
,◉ 14&6hz positive spikes. Answer: -posterior/temporal region (t5/t6)
-normal benign variant
-light sleep
-best seen in referential montage
-runs last less than 2 seconds
-seen in a lot of adolescents
◉ sleep spindles. Answer: -11-14hz , 1/2 second duration
-central regions
-asynchrony is abnormal after 2years old
-stage 2 sleep
◉ Hypnagogic Hypersynchrony. Answer: -2-6years old
-central/frontal regions
-paroxysmal bursts high voltage, 3-4.5hz
-normal variant of drowsiness
◉ Dilantin toxicity. Answer: ataxia (loss of control of body muscles)
◉ Laplacian montage. Answer: -source reference deviation
-looks at only the electrodes that are closest to the point of interest
-emphasizes localized waveforms
◉ deja vu. Answer: -complex partial sz
-automatisms/impaired consciousness
◉ extreme spindles. Answer: -found in MR (mental retardation) patients
-high voltage, anterior dominant
, -generalized
◉ OIRDA (Occipital Intermittent Rhythmic Delta Activity). Answer: -encephalopathy eeg pattern most
associated with children
-high amplitude, saw toothed, and reactive to eye opening
◉ Rolandic Spikes. Answer: -seen in children
-cento/temporal
-seen in benign rolandic epilepsy
◉ FIRDA. Answer: -Frontal Intermittent Rhythmic Delta Activity
-reacts to stimulation
-2-3hz
-rhythmic
-awake adult eeg
◉ Atonic seizure (drop attack). Answer: generalized seizure characterized by sudden loss of muscle tone
and strength; may cause the head to drop suddenly, objects to fall from the hands, or the legs to lose
strength, with falling and potential injury
◉ Tonic seizure. Answer: Muscle stiffness, rigidity
◉ photomyogenic response. Answer: -normal physiological response to photic light
-frontal leads
-only seen with eyes closed
◉ Photoparoxysmal response. Answer: -abnormal response to photic
-spikes, polyspikes, or spike/waves
-mostly seen in FQ >10hz
