As a result, interventions that target early childhood, particularly those that address the needs of at-risk parents; teach effective parenting strategies; promote the recovery of stress-response mechanisms in abused children; and enhance resilience, such as home visits by nurses Olds and parent skills training Webster-Stratton and Taylor , are likely to prove especially beneficial to children with risk-conferring genotypes.
The demonstration of a protective effect of supportive parenting in MAOA-L girls exposed to stressors, including abuse, is promising in this regard. Overinterpretation and oversimplification are two pitfalls that compromise the critical appraisal of neuroscience research, including research on sex differences. The differences described here represent differences between group averages; however, overlap between the two sexes is the rule rather than the exception.
The neurobiological correlates of violent behavior are not limited to interactions between the prefrontal cortex and amygdala, the mechanisms regulating stress hormones, or a single gene. Violence has polygenetic and multifactorial origins, involving contributions from interconnected networks of brain regions, multiple chemical signals both neurotransmitters and hormones , and multiple genes, all of which can be altered by a wide range of environmental factors.
Ongoing research to identify these factors and their interactions promises to further elucidate the etiology of violent behavior and, ultimately, lead to effective, biologically based intervention and prevention strategies. No competing financial interests exist. Login to your account Username.

Furthermore, criminal justice systems themselves—as well as the courts, foster care, schools, law enforcement and health care—can become additional sources of violence for survivors. In other words, she cautions that automatically calling the police when domestic violence occurs may lead not to safety, but to additional violence.
Bible should know, having spent more than 14 years working with domestic violence survivors charged with or convicted of crimes stemming from their abuse.
