CLTM Only Exam Material - Study Guide
In a patient with epileposy, which region of focus (by lobe of the brain) is known to have the greatest
incidence of NORMAL EEG? - Answer-Frontal Lobe
Seizures from here don't always show up on the EEG
Catamenial Epilepsy - What is it? - Answer-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) - Answer-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 the most common artery that infarction, emboli, ischemia, thrombosis, etc., may be seen at? -
Answer-Middle Cerebral Artery (MCA)
,What are the most common symptoms of Middle Cerebral Artery cerebral infarction? - Answer-
Contralateral face and arm/hand paralysis
C3 & C4
Arm/Hand Paralysis?
Face Paralysis? - Answer-Arm/Hand Paralysis
T3 & T4
Arm/Hand Paralysis?
Face Paralysis? - Answer-Face Paralysis
What is Compressed Spectral Array (CSA)? - Answer-Three dimensional display of EEG power spectral
lines.
What is Spectral Edge Frequency (SEF)? - Answer-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) - Answer-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) - Answer-Frequency in Hz
Where does the burst-suppression pattern come from in the brain? - Answer-Brainstem
, Only patients with what types of seizures qualify to have epilepsy surgery? - Answer-Partial or Focal
Epilepsies
The WADA is also known as: - Answer-Sodium Amobarbital Test
The Sodium Amobarbital Test is hemisphere dominant for __________ & _____ _____ ____ assessment.
- Answer-Language & Short Term Memory
NOT LONG TERM MEMORY OR SPEECH
What does the WADA process begin with? - Answer-It begins with selective angiography
What is Angiography? - Answer-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 - Answer-Proximal Internal Carotid
Artery
What kind of EEG activity would you see during a WADA? - Answer-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?
