Implication

Randomized trial reveals genetic and neurobiological links between impulsivity and procrastination in a twin cohort, suggesting biological origins for procrastination.

Key Points

This research investigates the shared neurogenetic bases of nonplanning impulsivity and procrastination, emphasizing genetic and neurobiological connections.
Longitudinal twin cohort study with 154 participants assessing nonplanning impulsivity and procrastination correlations.
Cross-sectional analysis in two additional cohorts (N=327; N=1,543) to replicate findings.
Meta-analysis of twin studies (N=3,656 twin pairs) and neuroimaging studies uncovering links to the left dorsolateral prefrontal cortex.
Twin modeling revealed significant shared genetic influences (r g = 0.51) on impulsivity and procrastination.
Neuroimaging meta-analysis identified the left dorsolateral prefrontal cortex as the region with the highest overlap between nonplanning impulsivity and procrastination.
Functional analysis of impulsivity genes showed associations with cortical metabolism and developmental expression peaks, indicating a common molecular basis.
