diagnosis and mgmt of epilepsy Flashcards
def of seizure
abnormal syncronous discharge of neurons in the cortex that produce sterotyped movements
what is epilepsy
2 or more unprovoked seizures
2 main seizure categories
- generalized
2. partial (focal)
2 main types of partials
simple - only in hand(or other) and otherwise fine
complex - changes in consciousness
describe generalized in terms of aura, LOC, post-ictal confusions
aura - none
LOC - altered
confusion - yes
describe complex partial in terms of aura, LOC, post-ictal confusions
aura - yes
LOC - altered
confusion - yes
describe simple partial in terms of aura, LOC, post-ictal confusions
aura - yes
LOC - no
confusion - no
4 types of generalized
- tonic-clonic - the one we think of
- atonic - full flaccid tone
- myoclonic - irreg. jerky movement of limbs
- absence - just zone out
describe absence in terms of age, aura, freq, duration, change to tonic-clonic, confustion
age - young aura - no freq - 100s/day duration -10-15 sec tonic clonic change - never confusion - none
describe partial complex in terms of age, aura, freq, duration, change to tonic-clonic, confustion
age - adult aura - sometimes freq - infreq duration -1-2min tonic clonic change - sometimes confusion - yes
lifetime risk of epilepsy and seizure
epi - 1%
seizure 5%
what is a primary cause of seizure
epilepsy
2 types of secondary causes of seizure and their causes
- structural - tumor, pus, blood, stroke
2. metabolic - non-adherance, hypoglycemia, EtOH withdrawl, drugs
where must a seizure originate
cortex - subcortical is not a seizure
what is sensitivity of EEG for detecting seizure
first EEG - 50%3
3 - 80%
