Answer 1

migraine
syncope
dizziness
seizure
transient global amnesia

Question 2

Answer 2

2 or more unprovoked seizures (not a/w alcohol withdrawal or meds known to cause seizures)

more common than people think (1/26)

Question 3

What carries strong stigma and prejudice?

epilepsy

Question 4

Absence seizure is also known as _____-

Answer 4

petit mal

Question 5

Can you diagnose epilepsy with a single EEG?

Answer 5

only Petit mal with hyperventilation (to see on EEG)

all seizures: can pick up only 40% with one EEG

generalized tonic-clonic: only 20%

Question 6

What can you do to pick up abnormalities on EEG for all seizure types?

Answer 6

3 sleep deprived EEGs (trigger)

Question 7

What is the most important information for epilepsy?

Answer 7

history via witness

Question 8

Define partial/focal seizures

Answer 8

seizure activity starts with one side of the brain:

simple partial

complex partial

secondarily generalized (starts partial then spreads)

Question 9

Define generalized/primary seizures

Answer 9

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

1-3 minutes

have post-ictal state

Question 14

Define secondary generalized seizure

Answer 14

LOC

lasts 1-3 minutes

post-ictal state

Question 17

Define atonic generalized seizure

Answer 17

sudden loss of muscle tone

head drops or collapse

LOC

variable duration

post-ictal state

Question 18

Define myoclonic generalized seizure

Answer 18

brief, rapid symmetrical jerking of extremities and/or torso

LOC

last few seconds

minimal post-ictal state

Question 19

tonic vs clonic

Answer 19

stiff vs jerking

Question 20

more for partial

Answer 26

valproic acid

Question 27

What drug is for absence/petit mal only?

Answer 27

ethosuxamide use until motor seizure

Question 28

What is the only synergistic combo of drugs for generalized seizures?

Answer 28

valproic acid lamotrigine

Question 29

Define status epilepticus

Answer 29

prolonged seizure >10minutes or repeat seizures without recovery in between

Question 30

Grand mal vs petit mal

Answer 30

grand mal: tonic-clonic with post-ictal state petit mal: staring without post-ictal both generalized seizures

Question 31

Treatment for status epilepticus

Answer 31

ABCs, IV gain hx (seizure, allergies) labs non-contrast head CT benzodiazepine (lorazepam) first thing--> buys time but must give longer lasting anti-epileptic drug (short acting) fosphenytoin or other anti-seizure IV if bad, need anesthetic to be intubated (midazolam or propofol) last resort: pentobarbital coma

Question 32

General traetment of epilepsy

Answer 32

try monotherapy d/t drug interactions (lots with oral contraceptives) consider long-term side effects (bone loss with carbamazepine or phenytoin)

Question 33

all women of child-bearing age should be on folic acid avoid valproic acid new drugs typically safer in pregnancy than older ones

Signs of seizure

Answer 35

urinary/bowel incontinence tongue injury (with tonic) tonic/clonic movements postictal state

Question 36

Define transient global amnesia

Answer 36

sudden, temporary, isolated episode of loss of memory no other neuro signs knows self and close family but not others lasts few hours then resolves usually doesn't recur benign
