WebNeurofilamentous axonal swellings occur in a number of degenerative and toxic disorders of the nervous system. In one of these, experimental intoxication with β,β' … WebSensorimotor polyneuropathy is a bodywide (systemic) process that damages nerve cells, nerve fibers (axons), and nerve coverings ( myelin sheath). Damage to the covering of the nerve cell causes nerve signals to slow or stop. Damage to the nerve fiber or entire nerve cell can make the nerve stop working.
WebApr 11, 2024 · Background and Objectives: Studies have suggested that, by applying certain nerve ultrasound scores, demyelinating and axonal polyneuropathies can be differentiated. In the current study, we investigated the utility of ultrasound pattern sub-score A (UPSA) and intra- and internerve cross-sectional area (CSA) variability in the diagnostic evaluation of … WebChronic idiopathic axonal polyneuropathy (CIAP) is a term describing neuropathies with both sensory and motor involvement in a length dependant distribution where …
