Extensive pathological and biochemical tests were performed, however the cause was found by studying a small population in which mutations in the eIF2B gene were found. No effective systemic studies have been conducted to determine the incidence around the world, but through the studies conducted thus far, it appears to be more prevalent in the white populations. VWM appears to have a lower number of cases in the Middle East, and Turkey has not yet had a reported case. Its prevalence is limited by the physician’s ability to identify the disease. As of 2006, more than 200 people have been identified with VWM, many of whom were originally diagnosed with an unclassified leukodystrophy.

There are no treatments, only precautions which can be taken, mainly to reduce trauma to the head and avoiding physiological stress. Melatonin has been shown to provide cytoprotective traits to glial cells exposed to stressors such as excitotoxicity and oxidative stress. These stressors would be detrimental to cells with a genetically reduced activity of protein eIF2B. However, research connecting these ideas have not been conducted yet.
