CLTM exam
VNS (vagus nerve stimulation) - CORRECT ANSWER-Dr. Zabara developed in
the mid-80s. FDA approved in 1997 for partial seizure onset.
VNS device is made of - CORRECT ANSWER-constant current pulse generator
and 2 platinum spiral electrodes; coiled around left vagus nerve.
VNS, how does it stop seizure? - CORRECT ANSWER-Thought to increase
inhibitory neurotransmitters and decrease excretory neurotransmitters. Blood
flow increases and decreases in different parts of brain also contributes.
FIRDA caused by: - CORRECT ANSWER-toxic metabolic encephalopathy
VSN seizure highest % decrease (year): - CORRECT ANSWER-3 years post
implantation
Lennox-Gastaut and VNS: - CORRECT ANSWER-these patients become more
alert and have better behavior control
Intermittent Rhythmic Delta Activity (IRDA) - CORRECT ANSWER-Is seen
maximal over the frontal or occipital lobes and can be caused by various
reasons, some benign or unknown, but also are commonly associated with
lesions and tumors. Gray matter is sick right now.
% of epileptic patients who are refractory to medication: - CORRECT
ANSWER-30%
Locus Ceruleusceruleus: - CORRECT ANSWER-A nucleus in the pons involved
with physiological responses to stress and panic; principal site for brain synthesis
of norepinephrine
Raphe nucleus (pons) - CORRECT ANSWER-main source of serotonin
Neurotransmitters have a big role in: - CORRECT ANSWER-Seizures and mood
modulation
