[A case of Sneddon syndrome started with 
neurological symptoms]

Sneddon syndrome(SS) is a rare clinical syndrome characterized by ischemic cerebrovascular disease and livedo reticularis, which involves the heart, kidney, fundus and other organs. We reported a case of a 45-year old male patient with recurrent ischemic cerebrovascular accidents as the first manifestation, accompanied by significant declines in cognitive function and livedo reticularis in trunk and limbs. The final diagnosis was SS. This article summarized the possible etiology, clinical characteristics, diagnosis and treatment for SS. Clinicians should improve the understanding of the disease to make the correct diagnosis and treatment and to prevent the occurrence of severe neurologic impairment and vascular dementia.
