polyradiculoneuropathy (AIDP),but some are caused by acute motor axonal neuropathy (AMAN) or acute motor and sensory axonal neuropathy (AMSAN).3 Primary axonal GBS is thought to be caused by an autoimmune attack on axonal antigens,and is common in Asia,but is responsible for less than 5% of GBS cases in Europe and North America.

In this form of neuropathy, a metabolic abnormality causes failure of protein synthesis and axonal transport, resulting in degeneration of distal regions of axons. For this reason, axonal neuropathies characteristically produce a "stocking-glove" distribution of numbness and weakness.

neuropathy should not be overlooked merely because of the diagnosis of mitochondrial disease, even where the association with neuropathy is well described. Reversible causes should be screened for in all cases. The nature of the neuropathy (axonal, demyelinating, or dorsal root ganglionopathy) and the level of clinical suspicion will guide further
