DEFINITION
Neuropathy is defined as a disease ori j f th i h l tinjury of the peripheral sensory, motor, or autonomic nerves.Can be : - pure motor
- pure sensorypure sensory- mixed sensorimotor
t i- autonomic

CategoryUsually categorized separately :
N th l ti i j t thNeuronopathy : selective injury to the cell body of the axonRadiculopathy : selective injury to the nerve roots distal to their originPlexopathy : injury to the brachial or lumbosacral plexusp

PATHOGENESISCan be divided into 4 major categories :1. Neuronal degeneration : results from damage to the motor or
ll b di i h b d isensory nerve cell bodies, with subsequent degeneration2. Wallerian degeneration : results from damage to the axon at
a specific point below the cell body, with degeneration distal t th i jto the injury.
3. Axonal degeneration : results from diffuse axonal damage. The distal portion undergoes the earliest and most severe h f ll d b d l i l t ith ti dchange followed by gradual proximal ascent with continued
injury (dying back phenomenon)4. Segmental demyelination : results from injury to the myelin
h th ith t i j t thsheath without injury to the axon
