Although many types of neurological disorders and events have been described in association with antiphospholipidantibodies(aPL) and the antiphospholipidsyndrome (APS), only ischaemic stroke is reasonably well established and accepted as a diagnostic criterion for the syndrome. We propose to evaluate, classify and rank the association of other neurological manifestations as possible, probable, or definite according to the data available from clinical studies and animal models. By these criteria, none of the neurologicaldisordersor events such as epilepsy, psychiatricdisease, dementia, transverse myelitis, multiple sclerosis-like disease, chorea, migraine, Guillian-Barrèsyndrome, and sensory-neural hearing loss, can be definitely associated with aPL or APS.
