Neurology: Early treatment is half the battle

Neurological diseases often begin with an inflammatory process and the degradation of the myelin layer, which surrounds the nerve fibers (axons) like a protective insulating layer. This is usually followed by damage to the nerve fibers (axonal neurodegeneration). The clock is now ticking: while the inflammatory process is still easily treatable in the early stages of neurological conditions, the relevant therapies are often no longer effective enough in the later stages.
