On April 4, 2013 our lives changed forever when our son, Sam Buck, was diagnosed with a very rare, untreatable brain disease called Vanishing White Matter disease. Vanishing White Matter disease (VWM), also known as Childhood Ataxia with Central Nervous System Hypomyelination (CACH), is a very rare condition that destroys myelin, the brain’s white matter. It is one of about 40 conditions that affect the white matter of the brain known collectively as Leukodystrophies. There are currently only about 250 people worldwide who are known to suffer from the disease. VWM is a chronic and progressive condition, and is unusual in that periods of rapid and severe deterioration can be caused by minor head trauma, fevers and even anesthesia. Few sufferers survive more than 5-10 years after onset. While every patient is different, as the disease progresses, sufferers can expect some or all or the following symptoms: loss of motor skills (walking usually goes first, followed by ability to sit unassisted, speech, use of hands, head control and ability to swallow), loss of vision, epileptic seizures, vomiting, irritability, and comas. Some patients die during coma; others recover slowly, but never to the same level as before. Since Sam’s initial bump to the head in February 2013, we have already seen his ability to walk severely affected, and he has tremors in one hand. During periods of deterioration, his speech becomes slurred and he becomes very irritable and tired. Symptoms generally appear in young children (usually between 2 - 6 years old) who were previously developing fairly normally. The severity of the disease is strongly correlated to the age of onset. Unfortunately for us, Sam was diagnosed very young and seems to be progressing very rapidly - a suspicion confirmed when we met Dr. Van der Knaap, the world expert on the disease, in Chicago.
