1

Define the problem of collapse

Seizures or syncope

2

Define wees a lot

Polyuric or pollakiuric

3

What is the pathophysiological approach to DDx?

DAMNIT V
- degenerative (eg. degen myelopathy)
- anomalous (eg. congenital hydrocephalus)
- metabolic (hepatic encephalopathy)
- nutirional/neoplasia (thiame deficiency encaphalopathy, meningioma)
- inflam/infectioius/idiopathic/iatrogenic (neosporosis, steroid responsive meningitis-arteritis, idiopathic epilepsy)
- trauma/toxin (metronidazole toxicity)
- vascular (fibrocartilagenous embolic myelopathy)

4

What is the 6 finger rule for neuro?

1. Localisation
2. Signalment
3. Onset
4. Progression
5. Symettry
6. Pain

5

egs. of focal lesions

- neoplasia
- intervertebral disk herniation
- congenital malformation

6

egs. of multifocal lesions

- inflam/infection
- multifocal neoplasia: lymphoma

7

egs. diffuse lesions

- neurodegenerative
- metabolic

8

What types of onset may be seen?

- peracute (instantaneous)
- acute (~days)
- subacute (~1/2weeks)
- chronic (weeks to months)
- acute on chronic

9

How can a pathology's progression be described?

-improving (trauma, vascular)
- static
- deteriorating (degenerative, inflam, neoplasia)
- waxing and waning (metabolic)
- episodic
- paroxysmal

10

How may a spinal cord lesion be symmetrical or asymmetrical?

> symmetrical
- intervertebral disk herniation compressing whole cord
> asymmetrical
- infarct as blood supply splits to left and right hemispheres of the cord

11

Where and which side is the lesion with circling animals?

circle towards the side of the lesion, forebrain lesion.

12

What MRI changes are seen with L2-hydroxyglutaric aciduria?

- metabolic dz
- brighter signal on MRI

13

Where are there no pain receptors in the spine?

- spinal cord
- all of CNS has no pain receptors

14

What is the most common brain tumour in the cat?

meningioma (mostly benign)

15

What type of onset does feline ischaemic encephalopathy have?

subacute onset/progression (vascular pathophysiology)
