CLTM EXAM STUDY GUIDE WITH QUESTIONS
AND VERIFIED ANSWERS
What is the most common artery that infarction, emboli,
ischemia, thrombosis, etc., may be seen at?
Middle Cerebral Artery (MCA)
What are the most common symptoms of Middle Cerebral
Artery cerebral infarction?
Contralateral face and arm/hand paralysis
C3 & C4
Arm/Hand Paralysis?
Face Paralysis?
Arm/Hand Paralysis
T3 & T4
Arm/Hand Paralysis?
Face Paralysis?
Face Paralysis
In a patient with epileposy, which region of focus (by lobe
of the brain) is known to have the greatest incidence of
NORMAL EEG?
,Frontal Lobe
Seizures from here don't always show up on the EEG
Catamenial Epilepsy - What is it?
Includes women whose seizures are exacerbated by their
menstrual cycle.
Women with catamenial epilepsy are unusually sensitive to
endogenous hormonal changes. This seizure exacerbation
has a statistically significant positive correlation to serum
estradiol/estrogen levels and ratios.
GAMMA
A gamma wave is a pattern of neural oscillation in humans
with a frequency between ___ and ___ Hz, though ___ Hz is
typical.
(Related to depth of anesthesia (patient state index)
A gamma wave is a pattern of neural oscillation in humans
with a frequency between 25 and 100 Hz, though 40 is
typical.
What is Compressed Spectral Array (CSA)?
Three dimensional display of EEG power spectral lines.
What is Spectral Edge Frequency (SEF)?
,Highest significant frequency present in the recorded EEG
spectrum for each epoch.
On the CSA, the Y Axis displays EEG as:
Frequency in Hz OR Power as a function (amplitude or mV)
Power as a function (amplitude or mV)
On the CSA, the X Axis displays EEG as:
Frequency in Hz OR Power as a function (amplitude or mV)
Frequency in Hz
Where does the burst-suppression pattern come from in the
brain?
Brainstem
Only patients with what types of seizures qualify to have
epilepsy surgery?
Partial or Focal Epilepsies
The WADA is also known as:
Sodium Amobarbital Test
The Sodium Amobarbital Test is hemisphere dominant for
__________ & _____ _____ ____ assessment.
Language & Short Term Memory
NOT LONG TERM MEMORY OR SPEECH
What does the WADA process begin with?
, It begins with selective angiography
What is Angiography?
Assesses arterial blood flow
Selective Angiography is a procedure in which visualization
is improved by concentrating the contrast media in the
region to be studied by injection through a catheter.
The Ambobarbital Sodium is injected via an arterial catheter
which is located at the ______________.
Proximal Internal Carotid Artery OR Proximal External
Carotid Artery
Proximal Internal Carotid Artery
What kind of EEG activity would you see during a WADA?
Slow activity (delta) in the hemisphere ipsilateral to the
injection.
**Ipsilateral hemispheric dysfunction & transient
contralateral paralysis
Excessive irrigation fluid of CSF in the field has which of
the following influences on the recording?
a. sixty cycle artifact
b. shunting with subsequent cancellation
c. no change
