Antiphospholipid antibodies and the central nervous system]

Among anti-phospholipid antibodies (APA), anti-cardiolipin antibodies and lupus anticoagulants are associated with arterial and venous thrombo-embolic manifestations. Antiphospholipid antibodies can be secondary to numerous diseases, especially systemic diseases, but they are usually encountered in the primary antiphospholipid syndrome. Neurological manifestations associated with APA are most often, if not always, ischemic in nature: large or small subcortical, often multiple, infarcts and transient ischemic attacks are the usual clinical presentations. Several mechanisms can lead to cerebral ischemia in the primary antiphospholipid syndrome, and their diagnosis is probably important for therapeutic choices. A prospective controlled study has started, which should provide data on the prognosis and management of this syndrome.
