Addictions are often characterized as forms of impulsive behavior. That said, it is often noted that impulsivity is a multidimensional construct, spanning several psychological domains. This review describes the relationship between varieties of impulsivity and addiction-related behaviors, the nature of the causal relationship between the two, and the underlying neurobiological mechanisms that promote impulsive behaviors. We conclude that the available data strongly support the notion that impulsivity is both a risk factor for, and a consequence of, drug and alcohol consumption. While the evidence indicating that subtypes of impulsive behavior are uniquely informative--either biologically or with respect to their relationships to addictions--is convincing, multiple lines of study link distinct subtypes of impulsivity to low dopamine D2 receptor function and perturbed serotonergic transmission, revealing shared mechanisms between the subtypes. Therefore, a common biological framework involving monoaminergic transmitters in key frontostriatal circuits may link multiple forms of impulsivity to drug self-administration and addiction-related behaviors. Further dissection of these relationships is needed before the next phase of genetic and genomic discovery will be able to reveal the biological sources of the vulnerability for addiction indexed by impulsivity.
Anatomical localization of brain regions involved in inhibitory response control or delay- or risk-related decision-makingFigure is color coded according to regions implicated in various laboratory measures of inhibitory response control. Abbreviations: Cg1, Cg2 = Zillesβ areas for anterior cingulate cortex; PrL = prelimbic cortex; IL = infralimbic cortex; OFC/VLPFC = orbitofrontal cortex/ventrolateral prefrontal cortex; Sep = septal nuclei; CPu = caudate/putamen nucleus; AcbC = nucleus accumbens core; AcbSh = nucleus accumbens shell; HC = hippocampus; STN = subthalamic nucleus.
LLM interpretation
This figure is an anatomical diagram showing coronal brain sections at three different Bregma levels (+3.72 mm, +1.20 mm, and -3.60 mm). Various brain regions (e.g., PrL, IL, CPu, HC) are color-coded to indicate their involvement in specific behavioral measures, such as SSRT and Go/No-Go (red), 5CSRTT premature responses (blue), and delay discounting (purple). The visualization maps the spatial distribution of these functional roles across the prefrontal cortex, striatum, and hippocampus.
Hypothetical models possibly explaining the relationships between forms of impulsive behavior and addictionOne model (A) proposes that each manifestation of impulsivity shares unique variance and mechanism with addiction behaviors. Another (B) suggests that these varieties of impulsivity share a small but measureable amount of variance and mechanism between them and that it is this overlap that is shared between them and addictions.
LLM interpretation
This figure consists of two conceptual diagrams (A and B) illustrating hypothetical relationships between addiction and four forms of impulsive behavior: Action Inhibition, Waiting, Delay-Related Decision-Making, and Risk-Related Decision-Making. In model A, addiction is represented as a base layer that shares a direct relationship with each individual form of impulsivity. In model B, addiction is positioned at the center, overlapping with the intersection where the four forms of impulsivity converge.
