Sturge-Weber syndrome (SWS) is a rare neurological disorder that is present at birth. It is characterized by a reddish-purple birthmark on the face, typically on one side of the forehead and upper eyelid, and sometimes involving the scalp and ear. This birthmark, called a port-wine stain, is caused by an abnormal buildup of blood vessels in the skin. SWS can also cause neurological problems such as seizures, developmental delays, and problems with vision and coordination. Treatment for SWS typically includes a combination of medications to control seizures and other symptoms, as well as laser therapy or surgery to reduce the appearance of the birthmark. Additionally, physical therapy and other therapies can help improve vision and coordination. It is important to note that the symptoms and severity of SWS can vary widely from person to person, and early diagnosis and treatment can help improve outcomes.
