[ 4 ] [ 3 ] [ 1 ] [ 5 ] Damage to the anterior cingulate cortex and to the striatum , which includes the nucleus accumbens and caudate nucleus and is part of the mesolimbic dopamine reward pathway , have been ...
In his works, he compares developmental disorders in traumatized children to adults with post-traumatic stress disorder, linking extreme environmental stress to the cause of developmental difficulties. [6] Other stress theories suggest that even small stresses can accumulate to result in emotional, behavioral, or social disorders in children. [7]
