“…Specifically, poor response inhibition has been associated with nonspecific physiological arousal making the behavioural inhibition system particularly relevant for the association between stress system dysfunction and ADHD (King, Barkley, & Barrett, 1998). Studies have reported attenuated HPA axis reactivity among children with ADHD and no comorbid conditions (Angeli et al, 2018; Isaksson, Nilsson, Nyberg, Hogmark, & Lindblad, 2012; Korpa et al, 2017; Ma, Chen, Chen, Liu, & Wang, 2010), associated with several of the core symptoms of ADHD (Pesonen et al, 2011). Moreover, there is inconclusive evidence for the associations between ADHD and autonomic dysregulation in children (Imeraj et al, 2012; Robe, Dobrean, Cristea, Păsărelu, & Predescu, 2019).…”
