Abstract

Throughout life, mechanisms such as damage and inflammation can alter the permeability of the blood-brain barrier(BBB). According to some studies, increasing the permeability of the blood-brain barrier can occur in a time-dependent manner following restraint stress. On the other hand, there have been reports of increased N-Methyl-D-Aspartate Receptor (NMDAR) -Ab seroprevalence in chronic stress conditions. The presence of antibody-secreting cells / memory B cells in the intrathecal area of the brain and their redistribution under various environmental stresses, which can be independent of the BBB status, are other points in this area that can emphasize the role of environmental stress in Anti NMDAR encephalitis. © 2021
