Epilepsy Flashcards
Sudden onset, self limiting episode of physical and/or psychological dysfunction caused by an abnormal burst of firing in the CNS is known as:
Seizure.
A neurological condition of various etiologies which affects the CNS and results in recurrent spontaneous seizures is known as:
Epilepsy.
Ictus/Ictal is used as:
Medical term for seizure activity.
Aura is known as:
Sensory hallucination.
Many seizures begin with them.
Location usually indicates type n vice versa.
What are the common aura experiences?
- tinnitus
- whirring or gong like sounds
- flashing lights
- apparent darkening of room
- paraesthesia
- smells or tastes (burnt toast, oranges, eggs, metal
Define triggers:
Immediate stimulus (sensory mainly) which initiates activity in the abnormal part of brain and pushes it beyond seizure threshold.
Common ones:
-strobe lights, flickering lights, rhythmic stimuli, loud noise, pain or emotional stress, complex patterns, allergies, complex functions, neuronal firing
What are destabilizing factors?
-background factors that make someone with epilepsy more sensitive or prone to seizure triggers.
They lower the persons threshold.
- recent injury/illness, lack of sleep, poor eating
- pain or emotional stress, alcohol/drugs
- irregular meds intake
- new meds or meds changes
What are some of the most common causes of epilepsy?
- genetic defect
- difficult birth
- head trauma
- infections (meningitis, encephalitis)
- cerebrovascular disease n stroke
- cardiac dysfunction or arrest
- kid episodes of high fever
- allergies
- suffocation or hypoxic incident
- severe shock (war, rape etc)
List the common types of seizures:
- tonic/clonic
- absence
- Jacksonian
- psychomotor
- akinetic/atonic
- myoclonic
What does Tonus mean in regards to seizures?
The entire body becomes rigid for about 1min.
Clonus means the entire body becomes flaccid for about 1-8minutes.
True or false?
False.
It becomes spasmodic
How does a tonic/clonic seizure begin?
Distinguishing factor.
See an aura first and will be the only part of the seizure they remember.
What’s often a sign that a tonic/clonic seizure is ending?
Urinary or fecal incontinence.
They have slow return to consciousness with confusion, fatigue and stupor for up to 48hours.
A person is considered in a state of status epilepticus on what occasion?
When they don’t come out of the seizure after 10mins or so.
Tonic/clonic seizures are most dangerous for the patient.
Absence seizures are a 10-30 sec loss of consciousness without loss of muscle tone.
True or false.
True.
- Minimal to no post Ictal symptoms.
- May have a mild tonic component
- Eyes roll back into sockets
- May froth at the mouth
