What is nonspecific white matter disease?
White matter disease is a disease that affects the nerves that link various parts of the brain to each other and to the spinal cord. These nerves are also called white matter. White matter disease causes these areas to decline in their functionality. This disease is also referred to as leukoaraiosis.
