Shared Neurogenetic Architecture Links Adolescent Neurodevelopmental Deviations to Adult Psychopathological Procrastination

A new study demonstrates that the same genetic factors shaping adolescent brain development also predispose individuals to pathological procrastination in adulthood. Using twin data, high‑resolution MRI and normative modeling, researchers identified overlapping neurogenetic signatures in cortical and subcortical regions linked to self‑control and reward processing. The analysis revealed significant genetic correlations between adolescent deviations from normative brain trajectories and adult procrastination scores, fitting within the NIMH RDoC framework for self‑regulation. These findings recast procrastination as a neurodevelopmental phenotype rather than a simple habit.
