Psychological stress and cortisol secretion in anhedonic alcoholic men.

We investigated plasma cortisol in a psychological stress paradigm in seven weaned anhedonic alcoholics in comparison with seven age-matched healthy controls. Alcoholics had significantly higher mean plasma cortisol at baseline and no increase following a psychological stress paradigm. Anhedonic alcoholics judged the experimental situation less agreeable than controls. Anhedonic alcoholics may have blunted cortisol response to psychological stress.
