Flashcards in Seizures - Epilepsy Deck (17):
1

Is the cause of epilepsy known?

No.

2

What is the etiology of epilepsy?

Provoked seizures (secondary)
Unprovoked seizures (primary)

3

What are some underlying causes for provoked seizures?

There is some genetic component involved - but is not well established.
CNS insult (infection, trauma)
Febrile seizures (kids)
Metabolic related: hypoxia, hypoglycaemia, electrolyte imbalance

4

What is the etiology of provoked seizures?

Mostly idiopathic and also has more genetic involvement than provoked seizures

5

What is epilepsy classified as?

Recurrent seizures

6

What is the patho of a seizure?

Epileptogenic cells are stimulated creating a discharge of increased amplitude and frequency, which spreads to other neurons. Normal neuron inhibition is blocked leading to abnormal muscle action and LOC.

7

What occurs just before a seizure is fully over?

Intermittent contraction-relaxation

8

What occurs once a seizure is over and why?

CNS depression because epileptogenic cells are completely inhibited

9

What is the phase called when CNS depression occurs after a seizure?

Post ictal phase

10

As a result from a seizure, an increase in ______ occurs. The body demands more _____ and ___

Metabolism
Oxygen
Glucose

11

Whether or not the body can meet metabolic demands during a seizure depends on what?

Length of the seizure

12

What is a complication of a seizure? Why?

Metabolic acidosis because the body's muscles are using anaerobic respiration to create energy

13

How are seizures diagnosed?

History (unless seizure is witnessed)
Neuro exam
Determine cause of seizure
Labs, scans, EEG

14

What is the treatment for a seizure? During, right after and later on?

During- protect individual from injury
STAT after- preserve brain fx
Later- underlying cause, anticonvulsant drugs & if drugs don't work surgery

15

Which type of seizure does someone lose consciousness from... Simple partial seizure or complex partial seizure?

Complex

16

What is a generalized seizure?

One that originates in both hemispheres of the brain

17

What is a partial seizure?

One that originated in only one hemisphere
