While both frontal lobe and hypothalamic-pituitary-adrenal (HPA) axis dysfunctions are influential factors in understanding criminal behavior, this discussion primarily focuses on the HPA axis and its neurobiological implications. The HPA axis is a central stress-regulating system in the body, intricately connected to the body's response to perceived threats. According to Jambroes et al. (2019), the HPA axis controls the release of cortisol, a glucocorticoid hormone that plays a crucial role in modulating the stress response. Dysregulation of this system has been linked to a spectrum of antisocial and criminal behaviors, especially those characterized by reduced fear and emotional responsiveness.

The HPA axis's dysregulation, particularly low activity, contributes significantly to antisocial traits such as callous-unemotional (CU) traits and antisocial personality disorder (ASPD). Jambroes et al. (2019) explain that individuals with ASPD often exhibit decreased HPA-axis activity, which correlates with low arousal levels. This phenomenon aligns with the fearlessness theory, which posits that individuals with reduced fear responses are less deterred by punishment or social consequences, thereby increasing their propensity for criminal activity (Jambroes et al., 2019). This reduced fear responsiveness facilitates aggressive and delinquent behaviors in youth, underscoring the neurobiological underpinnings of antisocial conduct.

Further supporting this assertion, Pompa (2006) observed that low HPA-axis activity correlates with not only antisocial behaviors but also adverse life outcomes such as social isolation and unemployment. These findings suggest that HPA-axis dysfunction creates a neurobiological foundation that predisposes individuals to a range of problematic behaviors and social disadvantages. Treatment responsiveness—or the lack thereof—in individuals with HPA-axis disturbances offers additional insights. Jambroes et al. (2019) highlight that such individuals tend to be resistant to conventional interventions, leading to persistent criminality and behavioral issues. This resistance may stem from the fundamental neuroendocrine impairments that underlie their psychological and behavioral traits.

Disruptions in HPA axis functioning are also intertwined with trauma and early life stress, further elucidating their role in criminal and maladaptive behaviors. Gowin et al. (2013) emphasize that early stressors, including child abuse, neglect, and prenatal insults, can alter HPA axis regulation, culminating in abnormal cortisol levels. These alterations are associated with mental health disorders such as post-traumatic stress disorder (PTSD), depression, and chronic stress conditions, which may escalate to aggressive and antisocial behaviors. Notably, individuals exposed to high-stress environments, such as homeless shelters and prisons, display heightened HPA-axis activity, reinforcing the link between sustained stress and neuroendocrine dysfunction.

Childhood sexual abuse escalates this pattern, as Gowin et al. (2013) found a significant association between early sexual victimization and the development of ASPD years later. This connection underscores the long-term impact of early adverse experiences on HPA axis regulation, reinforcing the biological basis for some forms of criminal conduct. The neurobiological model suggests that childhood trauma triggers persistent alterations in cortisol responses, which influence emotional regulation, impulse control, and social functioning. Such maladaptive neuroendocrine patterns predispose individuals to aggression, impulsivity, and psychopathy, thereby elevating their risk for criminality (Gowin et al., 2013).

From a forensic psychological perspective, understanding the neurobiological distortions caused by HPA axis dysregulation does not excuse criminal behavior but provides a nuanced context for its origins. Recognizing these biological factors can facilitate the development of targeted interventions, including trauma-informed therapies and neuroendocrine regulation strategies. Moreover, assessment tools integrating neurobiological indicators, such as cortisol levels and stress history, could enhance risk prediction and rehabilitation prospects. In sum, HPA axis dysfunction represents a vital component of the complex interplay between biology and behavior in criminality, emphasizing the importance of a multidimensional approach to understanding and addressing criminal conduct.
