title: [Axonopathy in the pathogenesis of multiple sclerosis, peripheral diffuse and local motor neuropathies and motor neuron disease].
abstract: Two hundreds and seventy-six patients including 43 patients with multiple sclerosis, 24 - with acute inflammatory demyelinating polyneuropathy (AIDP), 144 - with chronic inflammatory demyelinating polyneuropathy (CIDP), 27 - with motor multifocal neuropathy (MMN), 38 - with lateral amyotrophic sclerosis (LAS) have been examined. Symptoms of axonal degeneration, manifested in denervation phenomena in both clinical and instrumental studies (electromyography, transcranial magnetic stimulation, MRT), were revealed in all groups of patients. The formation of excitation conduction blocks is an universal pathophysiological mechanism of the axonopathy development in AIDP, CIDP, MMN and LAS. Symptoms of axonopathy and peripheral demyelinization in patients with multiple sclerosis and LAS suggest the possibility of transformation of immunopathological process from the central nervous system to the peripheral one.
