Research on the relationship between the role of stress and blood catecholamine levels began in the early 60's. Studies since that time have shown that both physical and psychological stressors can cause an increase in the circulating levels of catecholamines. Epinephrine and norepinephrine are the catecholamines most implicated as being affected by stress. The results have not been clear as to whether the two catecholamines respond differentially to physical and psychological stress. Epinephrine secretion appears to increase in response to anxiety while norepinephrine may be related to aggression.
