Several studies show that brain damage is associated with greater attention deficits and hyperactivity (Cruickshank, Eliason, & Merrifield, 1988 ODougherty, Nuechterlein, & Drew, 1984). Moreover, ADHD symptoms occur more often in children with seizure disorders (Hesdorffer et al, 2004, Holdsworth & Whimore, 1974). Such injuries are, however, unlikely to be the cause of ADHD in most of the cases as most cases of child ADHD have no annals of brain injuries of this sort. (Rutter, 1983).Research also shows that not only do the siblings of children with ADHD who also have ADHD show executive function (i.e. cognitive control) deficits, even those siblings who do not actually manifest ADHD appear to have impairments in the same functions, albeit milder.

However, some direct evidence from studies of cerebral spinal fluid indicates decreased brain dopamine in children with ADHD compared to nondisabled children (Halperin et al., 1997 Raskin, Shaywitz, Shaywitz, Anderson, & Cohen, 1984).
