Idiopathic sensory-motor polyneuropathy is an illness where sensory and motor nerves of the peripheral nervous system are affected and no obvious underlying etiology is found. In many respects, the symptoms are very similar to diabetic polyneuropathy.
The term peripheral neuropathy encompasses a wide range of disorders in which the nerves outside of the brain and spinal cordâperipheral nervesâhave been damaged. Peripheral neuropathy may also be referred to as peripheral neuritis, or if many nerves are involved, the terms polyneuropathy or polyneuritis may be used.hen an individual has a peripheral neuropathy, nerves of the PNS have been damaged. Nerve damage can arise from a number of causes, such as disease, physical injury, poisoning, or malnutrition. These agents may affect either afferent or efferent nerves.
