Children with antisocial and aggressive behaviors have been found to show abnormal neurobiological responses to stress, specifically impaired cortisol stress reactivity. The role of individual characteristics, such as comorbid anxiety, in the stress response is far less studied. Furthermore, this study extended previous studies in that not only baseline and reactivity to a psychosocial stressor were examined, but also recovery from a stressor. These three phases of cortisol could be impacted differentially in boys with oppositional defiant disorder/conduct disorder (ODD/CD) with (+ANX) and without anxiety (-ANX). The results revealed that cortisol patterns in response to psychosocial stress were different for boys with ODD/CD+ANX (n=32), ODD/CD-ANX (n=22) and non-clinical controls (NC) (n=34), with age range of 7.8-12.9 years. The ODD/CD-ANX group showed lower overall cortisol levels than the NC group. When considering the three phases of cortisol separately, the ODD/CD-ANX group ha...
The Diurnal Cortisol Cycle in Delinquent Male Adolescents and Normal Controls
Neuropsychopharmacology, 2007
Patterns of low hypothalamus-pituitary-adrenal (HPA) activity have been observed in antisocial groups. As conflicting results have been reported in children and adolescents, the aim of this study was to further investigate HPA activity in antisocial behavior by studying the relationship between the diurnal cortisol cycle, as well as the cortisol awakening response (CAR), and antisocial behavior in male adolescents. The diurnal cortisol cycle and the CAR during the first hour after awakening were compared between 12-to 14-year-old boys who attended a delinquency diversion program (DP), with and without a disruptive behavior disorder (DBD) (respectively DP + ; n ¼ 24 and DPÀ; n ¼ 65), and matched normal controls (NC; n ¼ 32). The DP + group, but not the DPÀ group, showed a significantly slower decrease of cortisol during the diurnal cycle than the NC group. Furthermore, the DP + group had significantly lower cortisol levels in the first hour after awakening as compared with the NC group. The results indicate altered HPA activity in delinquent boys with a DBD. Etiological mechanisms, directions for future research, and clinical implications are discussed.
A study of cortisol level as a biological marker in disruptive aggressive behaviour in adolescence
Benha Medical Journal, 2023
Background: Adolescence is usually associated with the teenage years, but its physical, psychological or cultural expressions may begin earlier and end later. Aggression is a behavior whose primary or sole purpose or function is to injure physically or psychologically. Aim and objectives: To demonstrate that high cortisol level in relation with the comorbidity of substance abuse and the duration of abuse in the conduct group. Patients and methods: This study was conducted on 50 aggressive patients with disruptive aggressive behaviors, attending the adolescent outpatient clinic at Alabbassia Mental hospital, who in turn divided into two groups one of conduct disorder and the other of Oppositional Defiant disorder and 25 resembling the control group during the period from March 2019 to February 2020. Results: Patients with conduct disorder showed statistically significant difference between the cortisol level and the comorbidity of substance abuse and the duration of abuse (by years) (P<0.05). While in the ODD group, there was statistically significant difference between the cortisol level and the gender and the age of the adolescent (P<0.05). Conclusion: Cortisol level is higher in the disruptive aggressive adolescents than that of the control group participating in the current study, moreover it was higher in those with conduct than ODD groups. It was demonstrated that high cortisol level in relation with the comorbidity of substance abuse and the duration of abuse in the conduct group.

Although several studies have associated antisocial behavior with decreased cortisol awakening responses (CAR), studies in adolescent samples yielded inconsistent results. In adolescence however, the CAR develops and antisocial behavior is heterogeneous in type and persistence. Therefore this longitudinal study compared persistent aggressive and rule-breaking adolescents to low aggressive and rule-breaking adolescents on the development of the CAR from ages 15 to 17 (N = 390). Persistently high aggressive adolescents showed decreased cortisol levels at awakening consistently over the years ( 2 (1) = 6.655, p = .01) as compared to low aggressive adolescents. No differences between adolescents showing persistent high rule-breaking and low rule-breaking were found. This longitudinal study is the first to show that persistent aggression, but not rule-breaking behavior, is related to neurobiological alterations. Moreover, despite development of the CAR over adolescence, the decrease in cortisol is consistent over time in persistent high aggressive adolescents, which is an important prerequisite for the prediction of persistent aggression.
Mood and Hormone Responses to Psychological Challenge in Adolescent Males with Conduct Problems
Biological Psychiatry, 2005
Background: Relations between stress hormones and antisocial behavior are understudied. Methods: A subsample (n ϭ 335) of at-risk males recruited in first grade for a longitudinal study were recruited at approximately 16 years of age for a laboratory study, including two psychological challenges: describing their worst experience on videotape, and a task in which a loud tone could be avoided. Measures of affect, urine, and saliva were collected multiple times before and after challenges. Results: Negative affect increased following the worst-event challenge and decreased following the avoidance challenge. Mean conduct problems (CP) across ages 7-17 years were positively related to negative affect and inversely related to positive affect. CP were inversely related to post-challenge urinary epinephrine (E) levels when baseline E and potential confounds were controlled. Cortisol concentrations in saliva collected soon after the first challenge were positively related to CP in a post hoc subset of youths with extreme CP. Conclusions: Key findings A) associated persistent CP with more negative affectivity and less positive affectivity, B) replicated and extended prior findings of an inverse association of CP and urinary E, and C) suggested provocative hypotheses for future study relating CP, trauma history, trauma recall, and cortisol reactivity.
Low basal salivary cortisol is associated with teacher-reported symptoms of conduct disorder
Psychiatry Research, 2005
Cortisol has been implicated in psychobiological explanations of antisocial behavior. This study measured basal salivary cortisol in a sample of 25 children (age range 6 to 12 years) selected to vary in levels of antisocial behavior. Regression analyses were used to predict cortisol concentrations from parent-and teacher-reported symptoms. Parent-reported symptoms did not predict basal cortisol. Teacher-reported conduct disorder (CD) symptoms explained 38% of the variance in the cortisol concentrations, with high symptom severity associated with low cortisol. When a distinction was made between aggressive and non-aggressive CD symptoms, aggressive CD symptoms were more clearly related to low cortisol than non-aggressive CD symptoms. In contrast to previous research, no evidence was found for a mediating role of anxiety symptoms in the relationship between CD and cortisol. The results support biologically based models of antisocial behavior in children that involve reduced autonomic activity. D
