Individuals with MBD usually have a history of excessive alcohol consumption, but this is not always the case. The mechanism of the disease is not completely understood, but it is believed to be caused by a Vitamin B deficiency, malnutrition, or alcohol use disorder. The damage to the brain can extend into neighboring white matter and sometimes go out as far as subcortical regions.
