Chapter 19 Seizures and Syncope Flashcards
A sudden and temporary alteration in the brain function caused by massive, continuing electrical discharge in a group of cells in the brain is known as
Seizure
jerky muscle contractions are known as
convulsions
what is a common cause of seizures
Epilepsy
What is epilepsy
a chronic brain disorder characterized by recurrent seizures
What is the most common type of epileptic seizures
generalized tonic-clonic seizure (grand mal)
how long does a generalized tonic-clonic seizure (grand mal) last
rarely more than a few minutes
What is meant by postictal state and how long does it last?
it follows a seizure and is the recovery period for the patient
up to 30 min
what are symptoms that a patient may have during postictal state
unresponsive extremely sleepy, weak, and disorientated or strokelike symptoms (paralysis)
what are other causes of seizures
injuries and other medical conditions
In regards to seizures is an EMT task to diagnose the type of seizure
NO….An EMT is to assess for and manage any life-threating conditions and provide reassurance to the patient
How are seizures categorized
Primary seizure and secondary seizure
which seizure is usually due to a genetic or unknown cause and are generalized or partial seizures
Primary seizure
what is meant by generalized seizure?
Generalized seizures involves both cerebral hemispheres (large Lobes) of the brain and the reticular activating system (wake/sleep system)
They produce loss of consciousness, either briefly or for a longer period of time, and are sub-categorized into several major types:
- Generalized tonic clonic seizures
- Myoclonic seizures
- Atonic seizures
- Absence seizures
what is meant by partial seizures
In partial seizures the electrical disturbance is limited to a specific area of one cerebral hemisphere (side of the brain).
Partial seizures are subdivided into simple or complex
A patient suffer from a simple partial seizure (focal motor or Jacksonian seizure) min will remain_________
retain consciousness
