Flashcards in Seizures, Cohen II Deck (43)
1
complex partial seizure
partial because 1 cerebral hemisphere
complex because level of consciousness partly reduced
2
signs before complex partial seizure
aura
deja vu
bad sensations: irritating smell or taste, sense of dizziness, abdominal discomfort that rises to head fast
3
patients who have complex partial seizures
any age, usually elderly
alone or witnessed to have TIA
may be from trauma
last 1-2 minutes
4
signs of complex partial seizure
sudden loss of speech, blank look on face, automatisms
5
what are the automatisms seen in complex partial seizure
repetitive blinking, chewing movements of mouth, simple motioning with the hands, odd fumbling with clothes or even undressing, repetition of very simple spoken phrases or words
6
how old are patients with absent seizures
4 or 5 or 6 y.o
7
common cause of seizures in children
absence seizures
8
petit mal seizures
absence seizures
9
length of absence seizures
less than 10 sec in duration
always less than 60 sec
inability to speak or respond in any way
10
do patients fall in absence seizure
no
11
after absence seizure
no idea had seizure
quick recovery of consciousness
12
MRI absent seizures
normal
13
Prognosis children with absence seizures
hundreds a day
poor in social situation or in school work
often Dx by teacher in kindergarten
frustrated parents
14
EEG absent seizures
three per second spike/wave complex
15
Tx absent seizure
usually respond to small dose of valproic acid (depakote)
lamotrigine (lamictal) effective
2/3 lose seizures after puberty
some go on to generalized tonic clonic seizure
16
ethosuximate
used for absence seizures
NOT tonic clonic
17
Antiepileptic drug usually not indicated
after first seizure with normal EEG and no risk factors
18
second unprovoked seizure
definition epilepsy and patients should take medication
19
90% or more seizures end in how much time
2 minutes or less
20
common damage from seizures
trauma: falling, including fractures or aspiration of gastric or oral contents or biting tongue or cheek
21
do not give what drug unless status epilepticus
IV benzos
22
what occurs with IV benzos if given to regular seizures
increased risk respiratory arrest
23
Pseudoseizures
psychologic nonepileptic seizures
usually have serious psychiatric illnesses
Hx of psychiatric or sexual abuse
24
what do pseudoseizures look like
asynchronous limb movements, eyes closed, involve pelvic thrusting or odd movements of trunk, go on for more than 2 minutes
come on more slowly than typical seizures
25
pseudoseizures do not responde to what drugs
epilepsy drugs
26
when do doctors need to reevlauate if patient truly has epilepsy or if medication not right for type of seizure
when patient has seizures after use of 3 different anticonvulsants at high doses
27
which type seizure patient more difficult to control with meds
partial epileptics
28
anticonvulsants
phenytoin
valproic acid
carbamazepine
lamotrigine
topiramate
29
side effects phenytoin
stevens johnson syndrome
30
phenytoin not useful in what patients
absent seizures
31
problems with carbamazepine
auto induction
dizzy
nausea
32
carbamazepine replaced by
oxcarbazepine
33
side effect lamotrigine
rash
34
side effect topiramate
slow down speech and thinking
changes the body temp
35
Status epilepticus
medical EM
36
risk of status epilepticus
permanent brain damage
lack of respiration may cause death immediately
37
definition status epilepticus
multiple seizures without regaining of normal level consciousness
or
prolonged generalized seizure for 30 minutes
38
are partial seizures that last 30 minutes dangerous
yes
39
Tx of status epilepticus
check ABCs, glucose and O2 and urine for toxicology
lorazepam or diazepam
40
loading dose for lorazepam or diazepam in status epilepticus
phenytoin or another anticonvulsant
41
first steps status epilepticus
ABCs
IV line
glucose and O2
42
surgery for seizure
if definite focal source of electrical discharge can be found, commonly in one of temporal lobes
surgical excision safe and highly effective
