1

What is a seizure?

Spontaneous electrical activity in the brain

2

What is the assumption for the pathophysiology of a seizure in animals?

There is a group of neurons that starts to spontaneously depolarize in succession (if in one part of the brain it is a seizure focus)

3

What happens if the seizure focus spreads?

It will affect the entire brain

4

What does grand mal seizure mean?

The entire cortex is involved

5

If the electrical activity remains in only one part of the brain, where will we see the manifestation of it?

We will see manifestation in the part of the body that the part of the brain controls

6

What are the clinical findings associated with seizures?

Spontaneous, uncontrollable, contraction or tremor like muscle movements, duration is 30-90 seconds, autonomic signs, and lack of consciousness

7

What autonomic signs are associated with seizures?

urination, salivation, and defecation

8

What are the classifications for seizures?

focal, generalized, and limbic/temporal/behavioral

9

What are the three general causes of seizures?

metabolic, structural, and idiopathic

10

What clinically important factors are vital for seizure classification?

age of onset of first seizure and if there are interictal neurologic deficits

11

What clinically important factors are associated with metabolic seizures?

The animal is less than 1 year of age or greater than 5 years old, and there are no interictal neurologic deficits

12

What are some metabolic causes of seizures?

Liver disease PSS, hypoglycemia, toxins, parasites, and anemia

13

What clinically important factors are associated with structural seizures?

The animal is less than 1 year of age or greater than 5 years old, and there are interictal neurologic deficits

14

What are some structural causes of seizures?

brain tumor, acquired hydrocephalus, encephalitis, cerebrovascular disease, and trauma

15

What clinically important factors are associated with an idiopathic seizure?

The animal is between 1 and 4 years of age and there are no interictal neurologic deficits
