title: Anti-phospholipid antibodies in cerebrospinal fluid but not serum from a boy with psychosis.
abstract: A 12-year-old African American boy with mental retardation and Asperger's disorder presented with acute psychosis. Antiphospholipid antibody testing with enzyme-linked immunosorbent assay showed increased levels of immunoglobulin G anticardiolipin antibodies in the cerebrospinal fluid, but not in the serum. Although antiphospholipid antibodies have been reported in the serum of patients with thrombotic and neurologic disorders, there are only a few reports of these antibodies in cerebrospinal fluid. This finding is consistent with a recent report of antiphospholipid antibodies found in the cerebrospinal fluid of adults with acute psychosis.
