Which of the following is the WORST prognostic feature in the EEG of a comatose
patient? - monorhythmic tracing without variability
SMALL SHARP SPIKES are also called - Benign Epileptiform Transients of Sleep
(BETS)
HYPSARRHYTHMIA shows - Disorganized, continuous high voltage slow waves with
interspersed multifocal spike waves
A seizure discharge arising from the right frontal lobe is likely to be characterized
clinically by - deviation of head and eyes
What is most important when evaluating the background activity? - Record the
maximal state of alertness
High voltage theta or delta waves, commonly seen in children 8-14 years,
accentuated by hyperventilation: - Posterior Slow Waves of Youth (PSWY)
A stroke which results in only LEFT leg weakness most likely involves which of the
following arteries? - The RIGHT anterior cerebral artery
Rare 6-11 hz negative sharp arciform waves, most commonly seen in adults over 30
years in the mid-temporal regions. - Wickets
A prolonged series of generalized convulsions without any period of consciousness
between them is referred to as - status epilepticus
What differentiates Lambda and POSTS - Occurs with eyes open
,If the Low Frequency Filter is changed from 1 Hz to 5 Hz, how will a 2 Hz slow wave
be affected? - It will be significantly attenuated
Creuetzfeldt-Jakob disease EEG shows - GPDs/GPEDS
Mu Rhythm is a frequency of - 8-10 Hz
In which of the following conditions are periodic lateralized epileptiform discharges
most likely? - Herpes simplex encephalitis
Photic induced epileptiform discharges are most likely associated with - barbiturate
withdrawal
Subacute sclerosing panecephalitis is associated with - Measles
Seizures commonly result from withdrawal of which of the following? - Alcohol
At what conceptional age is a delta brush pattern primarily seen? - 32 to 34 weeks
An electrographic seizure is characterized by - Episodic rhythmic activity
Which of the following occurs during a typical absence seizure? - Impaired
consciousness
What is the term that describes failure of the alpha rhythm to attenuate with eye
opening? - Bancaud's Phenomenon
INFANTILE SPASMS EEG shows - Electrodecremental Events
Slow sampling rate may cause fast frequencies to appear slower: - aliasing
The polarity convention for EEG states that the deflection is up if input - 1 is more
negative than input 2
The EEG pattern of hypsarrhythmia is usually associated with - infantile spasms
An EEG obtained within 24 hours following a closed head injury would be LEAST
likely to show - focal spike activity
Excessive beta frequency activity may be the result of which of the following? - Drug
effect
TIME CONSTANT - Low frequency filter
Photic stimulation is most effective in evoking epileptiform abnormailties in patients
with - a family history of seizures
, What normal activity would be seen most prominently at the C3 or C4 electrode
postion? - Mu
Patients with temporal lobe epilepsy may display ictal automatisms, which are: -
Stereotyped, repetitive movements, such as lip smacking or rubbing fingers together
Which of the following infectious diseases is most frequently associated with
periodic complexes in the EEG? - Herpes simplex encephalitis
What is most useful when determining localization and polarity? - montage
HYPNAGOGIC HYPERSYNCHRONY - can be present during arousal state transitions,
both prior to sleep and onset and following arousal
Which of the following is abnormal? - asymmetric attenuation of the alpha activity
Alpha coma is most often seen following: - cardiac arrest
Mu Rhythm is located ... - C3/C4
Hyperventilation should be done at a rate of: - 20 breaths per minute
Which neurologic syndrome may be associated with focal epilepsy? - Tuberous
Sclerosis Complex
Which of the following is characteristic of active sleep in a neonate? - Frequent
movements
Photoparoxysmal responses are characterized by: - Generalized irregular spike and
wave discharges or polyspike and wave bursts
A common electrographic correlate of a seizure: - Rhythmic activity
Which of the following patterns is characteristically eliminated by movement of a
limb? - Mu rhythm
Which is the most important when evaluating background frequency? - wakefulness
and age
When using the average reference, if a spike-and-wave focus appears at C3, the
abnormality would be best enhanced by - Excluding C3 and surrounding electrodes
from reference
In the majority of patients with arterial hypertension and acute pure motor
hemiplegia, and EEG with MOST likely show - normal activity
