Intrathecal Immunoglobulin Production and Minor Motor Seizures

Abstract

Five infants with idiopathic infantile minor motor seizures had an elevated immunoglobulin G (IgG) index ((cerebrospinal fluid IgG/serum IgG):(cerebrospinal fluid albumin/serum albumin)). The infants had prolonged prodromal symptoms, and bad prognosis. It is suggested that immunological mechanisms may contribute to the pathophysiology in certain cases of infantile spasms.
