Abstract
Background: Compulsivity, the closely linked trait impulsivity and addictive behaviour are associated with several
neurodevelopmental disorders, including attention-deficit/hyperactivity disorder (ADHD), autism spectrum disorder
(ASD), and obsessive compulsive disorder (OCD). All three disorders show impaired fronto-striatal functioning, which
may be related to altered glutamatergic signalling. Genetic factors are also thought to play an important role in the
aetiology of compulsivity-related disorders.
Methods: The COMPULS study is a multi-center study designed to investigate the relationship between the traits
compulsivity, impulsivity, and, to a lesser extent, addictive behaviour within and across the neurodevelopmental disorders
ADHD, ASD, and OCD. This will be done at the phenotypic, cognitive, neural, and genetic level. In total,
240 participants will take part in COMPULS across four different sites in Europe. Data collection will include
diagnostic interviews, behavioural questionnaires, cognitive measures, structural, functional and spectral
neuroimaging, and genome-wide genetic information.
Discussion: The COMPULS study will offer the unique opportunity to investigate several key aspects of
compulsivity across a large cohort of ADHD, ASD and OCD patients.
