Seizures/Epilepsy Flashcards
Seizure Definition
Transient excessive/synchronous abnormal electrical discharge of neurons in the brain
Epilepsy Definition
2+ unprovoked seizures
3 Ways to Classify Seizures
Symptoms (sens/motor/psych), distribution, or alteration of consciousness
2 General/Distribution Classifications
Partial (focal) seizures - start in localized area of cortex and can spread (secondary generalized seizure)
Generalized seizures - start in entire cortex at once, like in central trigger (thalamus)
2 Kinds of Partial Seizures
Simple - no change in consciousness/awareness
Complex - change
Simple Partial Seizures 2.2 Symptoms
Positive - sensory get tingling and hallucination
Motor get unilateral jerks or stiffness and Jacksonian march
Jacksonian March
Type of simple partial motor seizure where you get electrical discharge spreading along motor strip, so twitching that spreads across body hand-> mouth
Complex Partial Seizures 4 Symptoms
Automatisms
Aura
Postictal confusion
Postictal focal deficits
4 Kinds of Generalized Seizure
Tonic-clonic: increased tone then rhythmic movement
Absence - unresponsiveness
Myoclonic - brief, jerky movement
Atonic - lose tone and fall down
2 Other Features of Tonic Clonic
Epileptic cry and incontinence
EEG Reading of Absence Seizure
3 Hz spike/wave generalized discharges
Juvenile Myoclonic Epilepsy
Usually myoclonic (can be others) exacerbated by EtOH and sleep deprivation, so college kid
Lennox-Gastaut
Childhood syndrome w/ mental retardation that can have any kind of seizure
Benign Rolandic
Childhood seizures at night, either simple partial (mouth/face) or tonic clonic
AED Initiation Criteria
Begun after 2 seizures that aren’t provoked
