Sneddon Syndrome is a rare condition characterized by the combination of skin changes and neurological symptoms. It is not contagious and cannot be transmitted from person to person. The exact cause of Sneddon Syndrome is unknown, but it is believed to be an autoimmune disorder. The condition primarily affects small blood vessels in the skin and brain, leading to symptoms such as skin discoloration, stroke, and cognitive impairment. Sneddon Syndrome requires medical evaluation and treatment by a healthcare professional.
