Dandy-Walker complex

The long-term outlook for people with Dandy-Walker complex depends on the symptoms that are caused by the changes in the structures of the brain. The long-term outlook also depends on whether Dandy-Walker complex occurs alone (isolated) or whether there is an underlying genetic syndrome that may cause other health problems. Because the differences in brain structure and the presence of an underlying genetic syndrome may affect the signs and symptoms or life expectancy that a person has, it may be difficult to predict the long-term outlook for people who have Dandy-Walker complex.^[1][2]

Some people with Dandy-Walker complex may have physical disabilities or intellectual disabilities. In most cases, infants who have isolated Dandy-Walker variant are more likely to have normal outcomes in the newborn period.^[3]
