Primary antiphospholipid syndrome manifesting as partial status epilepticus.

Primary antiphospholipid syndrome (APS) is an autoimmune disease defined by vascular thrombosis, pregnancy complications, and persistent antiphospholipid antibodies. Neurological manifestations include stroke, seizures, and chorea among others. Seizures are often precipitated by an acute ischemic event, but occasionally, structural abnormalities are absent.
