Flashcards in Approaches to Patient with CNS Disorders Deck (24):
1

Define "Praxis"

The engaging, applying, exercising, realising, and practising of ideas

2

Inhibition of inappropriate behaviour is controlled by what area of the brain?

Frontal lobe

3

What are some symptoms of Frontal Lobe dementia?

- Disinhibited behaviour
- Bladder dysfunction
- Gait apraxia (magnetic gait)

4

Saccadic movements are controlled by what?

Frontal lobe / Frontal eye fields

5

Where are the legs of a human tropographically represented on the cerebrum?

Medial aspect of the brain

6

Where is the face / arms of a human topographically represented on the cerebrum?

Lateral aspect of the brain

7

What is an Upper Motor Neuron defined as?

Neurons above the level of the anterior horn cells

8

What is a Lower Motor Neuron defined as?

Neurons below the level of the anterior horn cells

9

Give examples of symptoms of a LMN lesion

- Flaccidity
- Hypotonic
- Hyporeflexic
- Babinski -ve

10

Give examples of symptoms of a UMN lesion

- Spasticity
- Hypertonic
- Hyperreflexic
- Babinski +ve

11

What is the name for the Descending motor neuron tract? How many neurones does this pathway have?

Corticospinal Tract, 2

12

A lesion in the right motor cortex will cause what motor symptoms?

Left sided (contralateral) upper motor neuron weakness

13

A lesion in the right cranial nerve nuclei will cause what motor symptoms?

Right sided (ipsilateral) lower motor neuron weakness

14

A lesion in the right side of the spinal cord will cause what motor symptoms?

Right sided (ipsilateral) Upper Motor Neuron weakness

Is above anterior horn cell, so UMN

15

A stroke affecting the Left middle cerebral artery will cause what motor symptoms?

Right sided (contralateral) Upper Motor Neuron weakness

16

A lesion in the right parietal cortex, internal capsule or thalamus will give rise to what sensory symptoms?

Left sided (contralateral) sensory deficit

17

A lesion in the left half of the spinal cord will give rise to what sensory symptoms?

Right sided (contralateral) sensory anterior column loss below level of lesion and left sided (ipsilateral) posterior column loss

Anterior column = decussates
Posterior column = does not decussate

18

Are Cranial nerves UMN or LMNs?

LMNs

19

Cerebellar lesions cause what sided lesions?

Ipsilateral (same side)

20

What are 7 features of Cerebellar dysfunction?

V: Vertigo
A: Ataxia
N: Nystagmus
I: Intention Tremor
S: Slurred Staccato
H: Hypotonia
D: Dysmetria

21

If there was an Oculomotor (CN III) lesion, what would you see in a patient?

- Eyes are down and out
- Dilated pupil (parasympathetic nerve)
- Ptosis

22

What is Horner's Syndrome caused by?

Sympathetic nerve supply is damaged

23

How is Horner's Syndrome characterised?

- Ptosis
- Anhidrosis (reduced sweating)
- Enopthalmos
- Miosis (constriction)

24

An Upper Motor Neuron lesion such as a stroke has what affect on the face?

Contralateral face weakness, sparing the forehead
