Cerebrospinal fluid viral antibodies in obsessive-compulsive disorder in an Indian population

Immunoglobulin G viral antibodies for herpes simplex virus type 1, varicella zoster virus, cytomegalovirus, measles, and mumps were studied in 76 subjects with obsessive-compulsive disorder and compared with a control population. There was a significantly higher titer for herpes simplex virus type 1 antibodies. Sera: cerebrospinal fluid ratios were suggestive of intrathecal synthesis.
