State of central and peripheral conduction tracts in patients with long-term chronic mercury intoxication

Abstract

In connected sample, the authors studied changes in state of peripheral nerves (electroneuromyography) and central afferent conduction tracts (somatosensory evoked potentials) in patients with long-term chronic mercury intoxication. The study helped to reveal negative changes in peripheral and central afferent conduction tracts in the patients with long-term chronic mercury intoxication, more marked in 3 period of the study - demyelination of sensory and motor components of peripheral nerves and longer impulse propagation time in conduction tracts of subcortical and cortical structures of somatosensory brain cortex.
