Corticospinal tract degeneration is a condition where the nerve fibers in the corticospinal tract, which is responsible for controlling voluntary movements, deteriorate over time. This can lead to various neurological problems affecting movement and coordination. In this article, we’ll explore the causes, symptoms, diagnosis, treatment options, and prevention measures for corticospinal tract degeneration in plain and accessible language.
Corticospinal tract degeneration refers to the gradual breakdown of nerve fibers in the corticospinal tract, a vital pathway in the central nervous system that facilitates voluntary muscle movements.
Types:
