title: Epilepsy associated with lupus anticoagulant.
abstract: BACKGROUND
  Lupus anticoagulant (LA) is commonly present in patients with systemic lupus erythematosus (SLE) who present with an ischemic cerebral stroke. Reports have noted the presence of LA in patients with epilepsy who do not have SLE. These patients are usually elderly, and it has been postulated that their epilepsy is due to subclinical ischemic infarcts.
  
  
  METHODS
  Two cases are presented in young patients (age < 35 years) who developed epileptic seizures and were LA positive. These patients did not have SLE or have cerebral infarcts that could explain the presence of their seizures.
  
  
  RESULTS
  A 28-year-old woman was admitted for aortic insufficiency and new onset seizures. The clinical history, physical examination and magnetic resonance imaging did not reveal an antecedent cortical ischemic event. Serological testing revealed the presence of LA. The second patient was a 33-year-old man with medically intractable epilepsy in whom serological testing revealed the presence of LA. The clinical history, physical examination, and MRI did not reveal any evidence of an antecedent ischemic event. Neither patient had SLE.
  
  
  CONCLUSIONS
  In young patients without SLE and cerebral infarcts, LA may be associated with epileptic seizures.
