<unk> es <unk>  is a name sometimes given to a group of different neuropathies which are all characterized by their impact upon both afferent and efferent neural communication.<unk>  are characterised by atypical neural development and degradation of neural tissue. The two common forms of<unk>  are either hypertrophic demyelinated nerves or complete atrophy of neural tissue. Hypertrophic condition causes neural stiffness and a demyelination of nerves in the peripheral nervous system, and atrophy causes the breakdown of axons and neural cell bodies. In these disorders, a patient experiences progressive muscle atrophy and<unk>  neuropathy of the extremities. The term<unk> " was used mostly historically to denote the more common forms Charcot–Marie–Tooth disease (CMT). With the identification of a wide number of genetically and phenotypically distinct forms of CMT, the term<unk>  is now used less frequently.
