b.inflammation

Question 5

a chronic onset of neurlogical symptoms indicates what

a.vascular
b.inflammation
c.tumour /degenerative

Answer 5

c.tumour /degenerative

Question 6

patient with waddling gait, reduced tone,no sensory impairment which investigation for location of the lesion

a.MRI brain
b.MRI spine
c.EMG-NCS
d.ACHr antibody
e.muscle biopsy

Answer 6

c.EMG NCS

symptoms typical of upper motor neurone

not spine or brain cos these are both upper motor neurone lesion

not AChr as these are for myasthenia gravis , key feature fatiguability , not present

not muscle biopsy has sensory dysfunction so cannot be muscle alone

do an EMG as peripheral neuropathy is suspected

Answer 7

a,axonal loss

Question 8

decreased velocity on EMG indicates what

a,axonal loss
b.demyelinating

Answer 8

b.demyelinating

Question 9

2 causes of demyelinating

Answer 9

chronic - chronic inflam demyelinating polyneuropathy

acute - guillian barre -acute demyelinating polyneuropathy
