Ch 3 - Epilepsy Flashcards
Prior to 2010 classification as seizures was?
Generalized
- Absence, atypical absence, tonic, tonic clonic, clonic, myoclonic, atonic
Partial
- simple, complex, secondary generalized
Atypical absence vs absence seizures
Atypicals are slower Hz than absence seizures, last longer, and are most common in developmental delayed patients.
LL AA DD
Simple vs complex partial seizures
simple = patient is aware
complex = awareness is lost
common example of simple partial seizure?
Aura
Where do auditory/oflactory/visual auras technically come from?
Auditory = temporal
Olfactory = medial temporal
Visual = occipital
Symptomatic vs idiopathic vs cryptogenic seizures?
Symptomatic = there is a known lesion causing sz
Idiopathic - presumed to be genetic, MRI is nl
Cryptogenic - thought to be symptomatic, but unknown
Post 2010 classification of seizures?
Generalized, focal, or unknown
Focal = one hemisphere
Generalized = both
Types of generalized seizures?
- Absence (normal, atypical)
- Tonic
- Tonic Clonic
- Clonic
- Myoclonic
- Atonic
Infantile Spasms - features?
- usually in first 3-7mo old
- generalized tonic-myoclonic szs often called “Salaam” or Jacknife attacks
Triad of Infantile spasms:
West Syndrome
- Hypsarrhythmia
- Infantile Spasms
- Developmental Delay
In the old West, when an infant seized, they all yelled ACTH and HID
Describe EEG pattern in Infantile Spasms
Hypsarrhythmia
Chaotic high amplitude, asynchronous slow activity with multifocal spikes
Treatment for infantile spasms? Second line?
ACTH
Topamax/Keppra
Treatment found effective in infantile spasms patients with tuberous sclerosis?
Vigabatrin
Triad of Lennox Gastaut Syndrome?
- At least 2 different seizure types
- EEG with 1.5-2.5 Hz spike and wave discharges
- Developmental delay
Lenox (expensive dish company) had the GREATEST sale: buy one seizure, get one free!
Landau Kleffner Syndrome - features?
Also known as acquired epileptic aphasia
- epileptic condition associated with language disturbances usually at 3-7 years of age.
- patients develop word deafness, receptive>expressive aphasia (language disturbances).
Landau sounds like Lambeau (Packers Stadium), fans scream disturbing language and deafeningly loud!
Landau-Kleffner Syndrome (acquired epileptic aphasia) -EEG features?
epileptiform discharges over the parietal and temporal regions
During sleep, can show ESES (electrical status epilepticus of sleep)
Childhood Absence Epilepsy - features?
generalized epilepsy that starts at 4-8 yo with brief staring spells.
Childhood Absence Epilepsy - EEG?
3 Hz spike and slow wave discharges
Childhood Absence Epilepsy - treatment?
ethosuxamide is used for absence and is the best option
What is the best choice for patients with absence and generalized tonic clonic seizures (2)?
VPA or LTG
