RATED A+ NEWEST!!!!
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.
Which function has the lowest risk of being affected if a temporal lobectomy is
performed in the dominant hemisphere?
Supplementary Motor Deficits
During functional mapping, afterdischarges are more likely to occur with
intensities greater than ____ mA.

_____________ are localized seizures and occur at an individual patient's
threshold AFTER cortical stimulation.
Afterdischarges
If the EEG displays persistent epileptiform activity after direct cortical stimulation,
what is the approach to stop the event?
Cold irrigation
The surgical treatment most beneficial for patients who have epileptic zones
overlapping eloquent cortex:
Multiple Subpial Transection
Preferred treatment for Lennox-Gastaut syndrome.
Multiple Subpial Transection OR Corpus Collostomy (Only if atonic seizures or
drop attacks are mentioned)
Surgical treatment for Rasmussens and Sturge Weber syndrome:
Hemispherectomy
If the diagnosis was Hypothalamic Hamartoma, what would be the surgery type?
Gamma Knife (Gelastic Seizures)
If the diagnosis was Rasmjussens Encephalitis, what would be the surgery type?
Hemispherectomy
If the diagnosis was Lennox-Gastaut with atonic seizures/drop attacks, what would
be the surgery type?
Corpus Collosotomy
, If the diagnosis was Sturge Weber Syndrome, what would be the associated
surgery type?
Hemispherectomy
If the diagnosis was a patient with epileptic zones arising from or overlapping the
eloquent cortex, what would be the surgery type?
Multiple Subpial Transection
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.
If the diagnosis was Temporal Lobe Epilepsy, what would be the associated
surgery type?
Focal Resection
Any catastrophic infant and early childhood epilepsies, what would be the
associated surgery type?
Hemispherectomy

infarction?
Contralateral face and arm/hand paralysis
C3 & C4
Arm/Hand Paralysis?
