Unlike the brain, where small lesions may go unnoticed and even larger areas of abnormality may remain silent for long periods of time, the spinal cord seldom experiences even a small insult without resultant clinically apparent motor or sensory manifestations. Although generally subject to many of the same disease categories as the brain, the spinal cord, because of the distinctive features and sometimes unique pathology of its afflictions, warrants its own issue of CONTINUUM. This edition, edited by Dr Dean Wingerchuk, also contains reviews of disorders of the spinal roots and the less common, but important, plexopathies.
