Peripheral neuropathy, often shortened to neuropathy, refers to damage or disease affecting the nerves. [1] Damage to nerves may impair sensation, movement, gland function, and/or organ function depending on which nerve fibers are affected. Neuropathies affecting motor, sensory, or autonomic nerve fibers result in different symptoms. More than ...
Nerve injury is an injury to a nerve.There is no single classification system that can describe all the many variations of nerve injuries. In 1941, Herbert Seddon introduced a classification of nerve injuries based on three main types of nerve fiber injury and whether there is continuity of the nerve. [1]
Nerve injury classification assists in prognosis and determination of treatment strategy for nerve injuries. Classification was described by Seddon in 1943 and by Sunderland in 1951. [ 1 ] In the lowest degree of nerve injury the nerve remains intact, but signaling ability is damaged, termed neurapraxia .
Hereditary neuropathy with liability to pressure palsy (HNPP) is a peripheral neuropathy, a condition that affects the nerves. [4] Pressure on the nerves can cause tingling sensations, numbness, pain, weakness, muscle atrophy and even paralysis of the affected area.
Axonotmesis mainly follows a stretch injury. These stretch injuries can either dislocate joints or fracture a limb, due to which peripheral nerves are severed. If the sharp pain from the exposed axon of the nerve is not observed, one can identify a nerve injury from abnormal sensations in their limb.
Polyneuropathy (from Greek poly- 'many' neuro- 'nerve' and -pathy 'sickness') 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. [1]
Nerve compression syndrome, or compression neuropathy, or nerve entrapment syndrome, is a medical condition caused by chronic, direct pressure on a peripheral nerve. [1] It is known colloquially as a trapped nerve , though this may also refer to nerve root compression (by a herniated disc , for example).
Sensory neuronopathy (also known as sensory ganglionopathy) is a type of peripheral neuropathy that results primarily in sensory symptoms (such as parasthesias, pain or ataxia) due to destruction of nerve cell bodies in the dorsal root ganglion. [1]
