Overview

Sneddon syndrome is a progressive condition characterized by livedo reticularis (bluish net-like patterns of discoloration on the skin) and neurological abnormalities.[1][2] Symptoms may include headache, dizziness, high blood pressure, heart disease, mini-strokes and/or stroke. Reduced blood flow to the brain may cause lesions to develop within the central nervous system. This can lead to reduced mental capacity, memory loss and other neurological symptoms. The exact cause of Sneddon syndrome is unknown.[1] Some familial cases have been described. It has also been associated with obliterating vasculitis and antiphospholipid antibody syndrome.[2]
