When a nerve is damaged, this is usually called axonal neuropathy. When the coating around a nerve, called myelin, is damaged, this is called demyelinating neuropathy.

It can be classified in several ways, such as whether it is inherited or acquired, whether it is rapid or insidious in onset, which part of the peripheral nervous system it affects (motor, sensory, autonomic), whether it has an axonal or demyelinating pattern on electrodiagnostic testing, or what it is caused by, e.g. metabolic, drugs.
