White matter disease is a progressive disorder caused by age-related decline in the part of the nerves (the white matter) that connect different areas of brain to each other and to the spinal cord. When it occurs in the basal ganglia part of the brain, this is called subcortical hyperintensities. Damage to the white matter results in the death and decay of injured cells, leaving empty areas in the brain — called lateral ventricles, which fill with fluid (a condition called leukomalacia). The dotted line in A is the identity line. I have MS. Helpful, trusted answers from doctors: Dr. Prof Frank Gaillard The scale divides the white matter in periventricular and deep white matter, and region each is given a grade depending on the size and confluence of lesions 1. They have a predilection for the periventricular white matter, optic nerves, and spinal cord but spare no part of the CNS. However, this difference equalized by year 3 of the trial (Beck, 1993). Periventricular White Matter Lesion (PWM) The white matter is where the axons of our brain do their work and also where the lesions are visible on the MRI imaging we use now. This supports our hypothesis that to some degree the three measures of white matter lesions are indicators of general brain white matter disturbance. This misnomer comes from health practitioners referring to it as such, but periventricular white matter is commonly occurring on the brain, and changes in this matter are common as people age. Noninv Med Imag 1984;1. In these 12, zones of atrophic perivascular demyelination were present in eight brains.
