CLTM Only Exam Material - Rebecca ClarkBash Study
Guide
1. 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
2. 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.
3. 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.
4. What is the most common artery that infarction, emboli, ischemia,
thrombo- sis, etc., may be seen at?: Middle Cerebral Artery (MCA)
5. What are the most common symptoms of Middle Cerebral Artery
cerebral infarction?: Contralateral face and arm/hand paralysis
6. C3 & C4
Arm/Hand Paralysis?
Face Paralysis?: Arm/Hand Paralysis
7. T3 & T4
Arm/Hand Paralysis?
EG power spectral
,Face Paralysis?: Face Paralysis
8. What is Compressed Spectral Array (CSA)?: Three dimensional display of
E lines.
9. What is Spectral Edge Frequency (SEF)?: Highest significant frequency present in the recorded
EEG spectrum for each epoch.
10. 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)
,11. On the CSA, the X Axis displays EEG as:
Frequency in Hz OR Power as a function (amplitude or mv): Frequency in Hz
12. Where does the burst-suppression pattern come from in the brain?: Brainste
13. Only patients with what types of seizures qualify to have epilepsy surgery?
: Partial or Focal Epilepsies
14. The WADA is also known as:: Sodium Amobarbital Test
15. The Sodium Amobarbital Test is hemisphere dominant for &
Assessment.: Language & Short Term Memory
NOT LONG TERM MEMORY OR SPEECH
16. What does the WADA process begin with?: It begins with selective angiography
17. 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.
18. 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
19. 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
20. Excessive irrigation fluid of CSF in the field has which of the following
influ- ences on the recording?
a. Sixty cycle artifact
b. Shunting with subsequent cancellation
c. No change
d. All channels record the same activity in frequency & amplitude: b. Shunting
with subsequent cancellation
Almost like a big salt bridge
