WebAxonal sensorimotor polyneuropathies carry an extensive list of differential diagnoses. Diagnosis is based on detailed history, physical examination, recognition of associated neurologic and non-neurologic features, and appropriate testing. Disease-modifying treatments are lacking in many cases. Man … Axonal Sensorimotor Polyneuropathies WebIn peripheral nerve disorders that are characterized by either wallerian degeneration or axonal degeneration, prognosis is less favorable because the axon must regenerate and reinnervate muscle, the sensory organ, blood vessels, and other structures before clinical recovery is noted.

WebPeripheral axons are susceptible to agents that interfere with axonal transport or energy metabolism. Toxic exposure causes axonal degeneration, which primarily affects distal nerve segments. However, certain agents primarily affect the proximal nerve segment. The precise mechanism for the development of the neuropathy is often unclear.
WebOnce a peripheral nerve is injured, the Wallerian degeneration (WD) process begins with Schwann Cell (SC) dedifferentiation and macrophages migration to the damaged nerve to clean the myelin debris and promote axonal regrowth. 1 These crucial steps have shown to be some of the processes affected in the aged nerve in vitro models.
