Polyneuropathy (poly- + neuro- + -pathy) is damage or disease affecting peripheral nerves (peripheral neuropathy) in roughly the same areas on both sides of the body, featuring weakness, numbness, and burning pain. It usually begins in the hands and feet and may progress to the arms and legs; and sometimes to other.

Peripheral neuropathy in a wide range of disease, including diabetes, CIPN, viral infections, and GBS, develops as a result of the interaction of various combinations of just six processes: altered metabolism, covalent modification, impaired organelle function with ROS/RNS, altered signaling, slowed axonal transport, and altered ion channel dynamics.

Chemotherapeutic agents cause many short and long term toxic side effects to peripheral nervous system that drastically alter quality of life. Chemotherapy- induced peripheral neuropathy (CIPN) is a common and enduring disorder caused by several anti-neoplastic agents. CIPN typically presents with neuropathic pain,

Jan 5, 2016. Neuropathy means a disease of, or damage to nerves. When it occurs outside of the brain or spinal cord, it is called a peripheral neuropathy. Mononeuropathy means one nerve is involved. Polyneuropathy means that many nerves in different parts of the body are involved. Neuropathy can affect nerves that.

Peripheral neuropathy (PN) is damage to or disease affecting nerves, which may impair sensation, movement, gland or organ function, or other aspects of health, depending on the type of nerve affected. Common causes include systemic diseases (such as diabetes or leprosy), vitamin deficiency, medication (e.g.,

Peripheral neuropathy, in the broadest sense, refers to a range of clinical syndromes affecting a variety of peripheral nerve cells and fibers, including motor, sensory, and autonomic fibers. Most peripheral neuropathies affect all fiber types to some extent.

The pathology of peripheral neuropathy is reflected in the spinal cord. Acute axonal neuropathy causes cental chromatolysis. Axonal neuropathy and distal axonopathy involving the bipolar neurons of the dorsal root ganglia cause degeneration of the central axons of these neurons in the gracile and cuneate tracts of the spinal cord.

An electrode placed further along the nerve's pathway measures the speed of impulse transmission along the axon. Slow transmission rates and impulse blockage tend to indicate damage to the myelin sheath, while a reduction in the strength of impulses at normal speeds is a sign of axonal degeneration. Electromyography.

Wallerian degeneration was initially described in experimental axotomy. Neuropathies characterized by Wallerian degeneration include those that are caused by trauma, infarction of peripheral nerve (diabetic mononeuropathy, vasculitis) and neoplastic infiltration. In distal axonopathy, degeneration of axon and myelin.

The pathological processes affecting peripheral nerves include degeneration of the axon, myelin or both. The various forms of polyneuropathy are categorized by the type of nerve affected (e.g., sensory, motor, or autonomic), by the distribution of nerve injury (e.g., distal vs. Proximal), by nerve component primarily affected.

Lesser degrees of slowing of nerve conduction velocity indicate peripheral nerve damage, which could be due to axonal loss as in axonal neuropathy or neuronopathy (pathology within the nerve cell body). Needle electromyography. Electromyography is ofen useful in confirming the presence of axonal degeneration.
