Peripheral Neuropathy Flashcards
symptoms of large motor fibre neuropathy
weakness, unsteadiness, wasting
reduced power
normal sensation
absent reflexes
symptoms of large sensory fibre neuropathy
numbness, pasaesthesia, unsteadiness
normal power
vibration and joint position sense decreased
absent reflexes
symptoms of small fibre neuropathy
pain and dyesthesia (pain on touch)
normal power and reflexes pin prick and temp reduced
symptoms of autonomic neuropathy
dizziness - postural hypotension
nausea/vomiting - gastroparesis
foot drop and high stepping gait are signs of neuropathy in the
common fibular (peroneal) nerve
wrist drop is due to a neuropathy in
radial nerve
claw hand is due to a neuropathy in
ulnar nerve
what is pseudoathetosis
loss of proprioception usually seen in the hands
clinical signs in pseudoathetosis
no vibration sense in hands
cerebellar signs (but with loss of proprioception)
odd movements of hands
what is radiculopathy
damage to nerve root
most common area of radiculopathy
spine
clinical features of radiculopathy
pins and needles
loss of reflexes
what is plexopathy
problem affecting brachial or lumbar plexus
common cause of plexopathy
trauma
common sign of plexopathy
distal and proximal asymmetric weakness
damage to 2 or morenerves is called
mononeuritis multiplex
how many nerves are affected in mononeuropathy
one
how are the nerves damaged
axonal loss
demyelination
acute demyelinating condition
onset is days-weeks
guillaine barre syndrome
clinical manifestation of guillaine barre syndrome
stars with tingling limbs and pain
quadaplegia in 2 weeks
ventilation problems
association with guillaine barre syndrome
post campylobacter infection
common cause of death in guillaine barre syndrome
respiratory distress/failure
treatment for guillaine barre
immunoglobulin infusion or plasma exchange
most common mutation in hereditary neuropathies
CMT1a
