Seizures. Flashcards
Epilepsy:
neurological condition, which affects the nervous system.
Seizure:
sudden episode of transient neurologic symptoms such as involuntary muscle movements, sensory disturbances and altered consciousness. A seizure is caused by abnormal electrical activity in the brain, which is often diagnosed on an electroencephalogram (EEG); over firing of neurons.
Seizures are caused by:
traumatic brain injuries, infection, stroke, degenerative changes in the brain, tumors; unknown cause.
Partial seizures:
simple partial, complex partial, and secondarily generalized.
Generalized seizures:
absence, atypical absence, atonic, tonic, clonic, tonic-clonic, myoclonic, and febrile.
Status epilepticus:
15 minutes of continuous seizures; medical emergency.
Generalized seizures…
go across both sides of the brain.
Auras may be experienced with…
simple or complex partial; sometimes tonic-clonic.
Simple partial:
<30 seconds; occur at any age; most common type; fully aware; normally no post-ictal phase.
Complex partial:
30 seconds to several minutes; may feel tired or confused for 15 minutes but won’t return to normal for several hours; experience automatism; aura is common; occurs in LG.
Secondarily generalized:
starts as other partial seizures in a single portion of the brain then spreads to others becoming a generalized tonic-clonic; grand mal seizure; will shriek when diaphragm tightens.
Absence/petit mal:
simple: blank stare 10-20 seconds.
complex: eye blinks, licking lips, rubbing fingers; 10-20 seconds.
no aura.
Atypical absence:
blank stare, somewhat responsive; eye-blinking and lip movements may occur; hard to distinguish with cognitive impairment; common in LG.
Atonic:
<15 seconds; will lose muscle tone, suddenly drop things; will remain conscious; common with LG.
Tonic:
<20 seconds; muscle tone increased, body stiffens; will occur during sleep; if person is standing, they will fall; common with LG.
Clonic:
length will vary; not seen often; seen more in newborn; rhythmic jerking - will be symmetric.
Tonic-clonic/grand mal:
last 1-3 minutes; will lose consciousness; tonic then clonic; bowel and bladder control is lost; will drool or foam at the mouth; familial tendencies; post-ictal phase; occurs in LG.
Myoclonic:
1-2 seconds; sometimes many will occur in a short time; fall asleep and body jerks; common in LG - get them up too quickly, subject to light or sound too quickly.
Febrile:
t cause brain damage; may have temp of 106, will do ice bath.
occurs most in 3-5 months; peaks at 17-24 months.
Psychogenic:
pseudoseizures; differentiate between real and fake with video EEG.
LG:
mixed seizure disorder; won’t see all 6 every time: tonic, atonic, myoclonic, atypical absence, tonic-clonic, complex partial.
will be taking high doses of seizure meds: tegretol, keppra, lamictal, dilantin.
Dilantin will cause:
gingival hyperplasia.
Tegretol will cause:
osteoporosis; in teens within 18-24 months.
Topamax is used…
with migraine and seizure prevention; antidepressant; appetite suppressant; decreases mentation.
