6

2 parts of the nervous system

Central and Peripheral

7

Slow in one direction, quick return

Nystagmus

8

5 cranial nerve tests

1. PLR
2. Menace
3. Corneal reflex
4. Gag reflex
5. Oculo-vestibular

9

Tests peripheral nerves and pathways in the spinal cord

Reflexes

10

Not a diagnosis but a symptom of abnormal brain activity or other disease

Seizures

11

3 stages of a seizure

1. pre-ictal
2. ictal
3. post ictal

12

Period before a seizure that may be unnoticed or animal may become needy or hide

Pre-ictal

13

Period of the seizure activity

Ictal

14

Period of a seizure where the animal is exhausted, has an increased temperature, and needs supportive care

Post-ictal

15

Primary epilepsy where animal has multiple seizures throughout their life
1-3 years of age

Idiopathic epilepsy

16

Phenobarbitol and Potassium bromide

17

Diazepam (valium)

18

Seizures caused by hypoxia, hypoglycemia, hypocalcemia, infx dz, lead poisoning, brain tumors, etc

Secondary epilepsy

19

Emergency situation that can result in coma or death
Repeated clusters of seizures or seizure episode lasting 5-10 mins
Poor prognosis

Status Epilepticus

A congenital dz associated with a virus when kittens are exposed in utero
C/S is uncoordinated movement
Tx is supportive care

Cerebellar hypoplasia

27

Feline Panleukopenia

28

Rare but seen in small, brachycephalic dogs
Fluid accumulation around the brain
C/S: lack of training, excess sleepiness, vocalization, blindness and seizures
Tx: Diuretics or drain the fluid

Hydrocephalus

29

A plug in a vessel that obstructs circulation that results in infarct tissue
C/S depend on location

Embolus

30

Acute nonprogressive disturbance of vestibular system
Can be idiopathic or related to otitis
C/S: off balance, head tilt, circling, ataxia, nystagmus, falling, rolling
Tx: supportive care but may recur

Vestibular dz
