Workup
The most commonly used neuroimaging tool to observe seizures
Phase during seizure timeline during which some patients can identify they're about to have a seizure
Aura
A pharmacological intervention for acute or short-term seizure
Most common risk factor for seizures in children
Infection
Ambulatory EEG
True or false: patients are always unconscious in the ictal phase of a seizure
False
Ethosuximide is an Ca2+ channel blocker AED used in this kind of seizure
Absence
Standard part of adult first-seizure workup not typically done in children
Invasive labs
Indications for a sleep-deprivation EEG
1. Ensuring patient is asleep during collection
2. Lowering threshold for potentially observable seizure activity
True or false: strange smells can be perceived during multiple stages of seizure
True - aura (beginning) and ictal (middle)
This AED is also used as a mood stabilizer
Valproic acid
Happy Friday!
Here are some free points. Thanks for playing.
Most relevant/important step in diagnostic workup
Injury or blunt force head trauma can be observed in this seizure stage
Post-ictal
Carbamazepine class and mechanism of action
Na+ channel blocker, prevents repeated neuronal firing
1. Block voltage-sensitive sodium channels @ axon terminal of presynaptic neurons
2. Bind to channels opening and closing the most, forcing them to stay closed longer
Pharmacological intervention typically adopted in children for first unprovoked seizure
None - "wait and see" policy
Absence seizures exhibit this waveform on EEG
3 Hz-spike-and-wave pattern
Also known as "march of convulsions," this symptom is seen in _____ kind of seizure
Jacksonian march, seen in simple partial/focal
Topiramate increases the frequency of this channel's opening
GABA-A
Most likely kind of seizure that Olivia had
