Diagnosis
Diagnosing Dandy-Walker syndrome typically involves a series of tests conducted by medical professionals. The initial step is usually a fetal ultrasound, which provides a visual representation of the brain. However, for a more accurate and conclusive diagnosis, an MRI is recommended after the 20th week of gestation. Unlike ultrasound, an MRI allows for detailed imaging of the brain structure, providing a clearer understanding of the condition. Interestingly, it is possible to diagnose prenatal Dandy-Walker syndrome as early as 18 weeks into the pregnancy, when the affected parts of the brain have fully developed.
Treatment
In the treatment of Dandy-Walker syndrome, the primary focus is on reducing pressure on the brain. One commonly used procedure is the ventriculoperitoneal (VP) shunt. This involves the insertion of a narrow plastic tube that helps drain fluid from the ventricles into the abdomen. By doing so, it prevents the accumulation of fluid and the subsequent increase in brain pressure. Seizures can be managed effectively through the use of medications, while occupational or physical therapy can be utilized to enhance motor skills.
