Methods: We conducted a systematic search using Cochrane guidelines and PRISMA criteria in PubMed, Scopus, Web of Science, Cochrane Database of Systematic Reviews and Database of Abstracts of Reviews of Effects. Results: Results revealed broad encephalic involvement that includes a functional frontal and cingulate hypoactivation and structural differences in corpus callosum, cerebellum and basal nuclei. Conclusions: ADHD symptoms might be due to a multi-network unbalanced functioning hypothesis.engAttention Deficit Disorder with HyperactivityHumansNeuroanatomyjournal article10.1080/87565641.2017.1414821
