In traditional neurologic teaching, white matter has been regarded as a component of the brain that is primarily dedicated to elemental sensory and motor function; thus, the major problems produced by white matter lesions include visu-al field deficits, hemihypesthesia, and hemiparesis. Neurologists frequently encounter patients whose MR imaging shows white matter abnormalities. Such patients may present with various symptoms and signs, including cognitive deficits, movement and gait disorders, ataxia and many others.
