In turn, because MR and GR not only regulate the activity of HPA axis, but also actively participate in cognitive processes (30–33, 80), the assumed pronounced disturbances in the ratio of MR: GR in primates with DAB can contribute to intergroup and age differences in the cognitive abilities of primates, as well as post stress syndrome, psychiatric and possibly neurodegenerative diseases. The gene discussed is NR3C1; the disease is neurodegenerative disease.
