Early diagnosis and treatment are critical to minimizing the short- and long-term impacts of these disorders, as many of the symptoms may be reversible. Duke specialists are committed to diagnosing these diseases early and beginning treatment rapidly, to minimize symptoms and maximize your child’s recovery.
