When does the onset of Sturge-Weber disease typically occur?

Sturge-Weber disease typically presents during infancy, which is significant because it is a neurocutaneous syndrome that is characterized by facial angiomas and neurological complications. The condition arises from a congenital malformation of blood vessels, often associated with a port-wine stain on the face. As affected individuals grow, they may experience neurological symptoms, including seizures, which can manifest in the first year of life.

Early recognition and diagnosis are crucial for managing the complications associated with this condition. In contrast, the other age options, such as at birth, adulthood, or during adolescence, do not align with the typical clinical presentation, since symptoms often emerge as the child develops, making infancy the most appropriate phase for the onset of the disease.
