When does Sturge-Weber disease typically onset?

Sturge-Weber disease typically onsets in infancy, which is aligned with the correct answer. The condition is a neurocutaneous syndrome associated with a facial capillary malformation, often referred to as a port-wine stain, and neurological abnormalities due to associated leptomeningeal angiomatosis. The manifestations of the disease, including developmental delays, seizures, and various neurodevelopmental issues, often become apparent during the first year of life.

This early onset is significant for diagnosis and management, as interventions may be necessary to address the neurological complications that can arise. If the onset occurred in adolescence, elderly years, or adulthood, it would be inconsistent with the established clinical presentation and pattern of symptoms, as these populations are typically not presenting with the disease. The understanding of Sturge-Weber disease and its early indicators is crucial for timely intervention and support for affected individuals.
