[Dynamics of immunoglobulin levels and neuroimmune processes in intellectually deficient children].

The study of immunoglobulin levels and neuroimmune processes in younger schoolchildren with slightly retarded intellectual development revealed the deficiency of immunoglobulin A (either alone or in combination with other types of immunoglobulins). The neuroimmune processes identified were characterized by the presence of brain antibodies predominantly against interspecific antigens. During psychostimulant and general somatic therapy, the concentration of immunoglobulins tended towards normal and the intensity of neuroimmune processes declined.
