Abstract
Although many psychoactive substances have been associated with violent behavior, only a subgroup manifests excessively aggressive behavior when sober or intoxicated. Theories to explain addictive behaviors in general may directly relate to the specific proclivity to exhibit excessive aggression in this subset of users. Certain personality traits and cognitive deficits coexist in individuals prone to both drug abuse and violence, suggesting a common origin. Because these excessive and compulsive behaviors have been linked with aberrations in the metabolism and activity of the neurotransmitters dopamine and serotonin, their origins may be partly genetic or biological. Alterations in neurotransmitter function influence activities within the brain's reward center to perturb nervous system arousal levels, thereby increasing stimulation-seeking behaviors. Manifestations of these neurobiological aberrations can be measured in physiological and biochemical processes that serve to mediate these behavioral and psychological outcomes.
