16
Q

is juvenile myoclonic epilepsy a lifelong condition or specific to juvenile aged patients?

A

lifelong

17
Q

febrile seizures occur in what age range?

A

3 months - 6 years

18
Q

what is the most common seizure in children?

A

febrile

19
Q

what is the duration and frequency of simple febrile seizures? what if it is more frequent / longer?

A
  • 15 minute duration, once per day

- if more than that, it is a complex febrile seizure

20
Q

what should be the first concern for febrile seizure (pathogen)?

A

meningitis

21
Q

how do you differentiate between febrile seizure and meningitis?

A

history and possibly LP

22
Q

what is the diagnostic workup for febrile seizure?

A
  • LP for meningitis s/sx
  • LP for children 6-12 months of age if not vaccinated for HIB / s. pneumo
  • LP for patient taking abx
  • CBC / electrolytes / blood sugar / Ca / Mg
  • imaging: heat CT, MRI (**NOT FOR SIMPLE FEBRILE)
23
Q

is CT / MRI indicated for simple febrile seizure? what about EEG?

A

NO (to both)

24
Q

what is the treatment for febrile seizure?

A
  • seizure abortion: benzodiazepine (if longer than 5m)
  • febrile status epilepticus: treat like afebrile
  • prophylactic antiepileptic medications are not indicated given benign nature
25
Q

what are the 3 types of infantile spasm?

A
  • flexion: sudden flexion of legs, arms, neck, head
  • extension: sudden extension of head, neck, arms
  • mixed: flexion of head and arms with extension of legs
26
Q

what are the features of infantile spasm?

A
  • occur in clusters
  • occur on awakening from sleep
  • usually associated with developmental arrest or regression
27
Q

what are the different etiologies of infantile spasm?

A
  • symptomatic IS: identified etiology and / or significant developmental delay
  • cryptogenic IS: no known etiology and normal development
28
Q

what are the causes of infantile spasm?

A
  • CNS malformation (common cause)
  • tuberous sclerosis (common cause)
  • hypoxic ischemic encephalopathy
  • inborn error of metabolism
  • chromosomal abnormalities
  • congenital infection
29
Q

infantile spasm is associated with what characteristic EEG abnormality?

A

hypsarrhythmia

30
Q

hypsarrhythmia on EEG indicates what condition?

A

infantile spasm

31
Q

what is the treatment for infantile spasm? what about infantile spasm due to tuberous sclerosis?

A
  • ACTH

- vigabatrin

32
Q

vigabatrin is reserved for what condition?

A

infantile spasm due to tuberous sclerosis

33
Q

what test should follow vigabatrin administration? why?

A

eye exam - side effect is visual field restriction that could be permanent)
