Absence seizure is also known as _____-
petit mal

only Petit mal with hyperventilation (to see on EEG)
all seizures: can pick up only 40% with one EEG
generalized tonic-clonic: only 20%
What can you do to pick up abnormalities on EEG for all seizure types?
3 sleep deprived EEGs (trigger)
What is the most important information for epilepsy?
history via witness
Define partial/focal seizures
seizure activity starts with one side of the brain:
simple partial
complex partial
secondarily generalized (starts partial then spreads)
Define generalized/primary seizures
seizure starts in both sides of brain (genetic):
Absence (petit mal)–> staring
Tonic-clonic (unconscious, switch between arms in and out)
Myoclonic (brief jerks)
Tonic (arms outstretched and stiff)
Clonic (arms flexed, jerking)
Atonic (limp and fall to ground, completely lose tone)
Clonic-tonic-clonic
CAN HAVE MORE THAN ONE AT A TIME
Most adult onset of epilepsy have what type of seizures?
partial
What is a well-known medication that causes seizures?
tramadol
Define simple partial seizure
focal motor or sensory activity
no LOC
last seconds
no post-ictal state
Define complex partial seizure
nonresponsive staring
possible preceding aura
automatisms (pick at clothing, reaching for something, mouth movements)
LOC
1-3 minutes
have post-ictal state
Define secondary generalized seizure
starts partial but evolves to bilateral tonic-clonic activity
LOC
lasts 1-3 minutes
post-ictal state
Define absence generalized seizure
AKA petit mal
nonresponsive staring
rapid blinking, chewing
clonic hand motions
LOC
lasts 10-30 seconds
no post-ictal state
