Isolated Toe Tremor Associated with Antiphospholipid Syndrome.

ABSTRACT

The antiphospholipid syndrome (APS) is defined by the presence of antiphospholipid antibodies and related disorders, generally thromboses, miscarriages, livedo reticularis or heart valve abnormalities. It is thought to have a prevalence of about 40-50 cases per 100,000 in the general population.1 Several neurological disorders have been associated with APS, most commonly stroke, but non-stroke complications, thought due to auto- immune problems, have been noted, with chorea being the most common. Isolated toe tremor, that is, without any other neurological signs or symptoms, has not been reported. We describe a case of recurrent isolated uni- lateral toe tremor in an otherwise healthy woman with long-standing APS.
