What are the symptoms and signs of motor neuropathy?
a
What are the symptoms and signs of sensory neuropathy?
a
What are the symptoms and signs of autonomic neuropathy?
a
Describe the three types of damage to a peripheral nerve
Axontmesis
Demyelinating neuropathy
Axonal neuropathy
What is axontmesis nerve damage?
Nerve damage with nerve covering intact
What is demyelinating neuropathy?
Nerve cells lose myelin which don’t grow back
Slow conducting velocity => dispersed action potential
What is axonal neuropathy?
Axon damage won’t grow back
Normal conduction velocity
Small compound muscle action potential - fibrillation
Describe the basic conduction of a peripheral nerve
Conduction velocity along axon
Action potential at terminal
Compound motor action potenetial
How do we classify a neuropathy?
Type
Number
Aetiology
Timing
Pathology
What are the types of peripheral neuropathy?
Sensory
Motor
Autonomic
Mixed
How many nerves can be affected?
Mononeuropathy = one
Mononeuritis multiplex = a few
Polyneuropathy = many
Give an example of a mononeuropathy
Compression
Give an example of a mononeuritis
Vasculitis
Give an example of a polyneuropathy
Guillan Barre Syndrome
What are the two aetiology categories of neuropathy?
Congenital
Acquired
