“…The symptoms reported in the scientific literature supports the idea that the cerebellum is important for behavioural control and part of a dysfunctional brain network in ADHD as indicated by volumetric reductions of the cerebellar vermis and behavioural parent ratings of ADHD in medication-naïve adults [ 5 , 6 ]. In addition, previous studies have linked partial RES and other abnormalities of the vermis to symptoms associated with stereotypical behaviours and limited social skills, as well as impaired executive functions and emotion regulation, as seen in children with autism spectrum disorders (ASD) [ 7 – 9 ]. As children with ADHD-related symptoms often show ASD symptomatology and there is substantial overlap of symptoms in both disorders [ 10 ], the cerebellum may present a shared neural correlate.…”
