Bad Genes, Bad Moms, and Bad Brains: A Casual Biology of Poor Self-Control
From deciding between a cupcake and a carrot to choosing a retirement fund, we’re all faced with the need to delay gratification in order to achieve long-term goals. While everyone indulges temptation occasionally, highly impulsive people consistently make immediate-focused choices with serious adverse consequences. Impulsivity is a stable trait that is associated with profound individual dysfunction and impairment, and causes significant financial costs society-wide. While we know that "bad genes" and "bad environments" can account for most of the variability in impulsivity, the specific systems-level neurobiological mechanisms through which these factors act to affect behavior are poorly characterized. Using a combination of pharmacological, genetic, and multi-modal brain imaging approaches, I will provide evidence that specific "bad genes" (MAOA, DRD2, and LEPR) selectively disrupt information processing within brain circuits for emotional arousal and reward motivation. Finally, I will show that a specific "bad environment" (childhood maltreatment) is associated with dysfunction in these same circuits, possibly accounting for observed gene-by-environment interactions in risk for psychiatric disorders characterized by poor self-control.
