ADHD a common, and commonly co-
occurring, disorder
•
Attention-deficit/hyperactivity disorder (ADHD) refers to the
presence of pronounced difficulties in the areas of inattention,
distractibility, and hyperactivity that lead to significant impairments in
academic and social functioning (American Psychiatric Association, 2013).

•
ADHD is one of the most commonly diagnosed clinical conditions affecting
approximately 5-7% of the student population (Willcutt, 2012).

•
Co-occurring ADHD and communication disorders represent a frequently
encountered challenge for school-based practitioners (American Speech
Language Hearing Association, 2008).

•
Determining the source of children’s academic and social difficulties as
either language-based, attention-based, or a combination of both can be a
daunting task for assessment teams.
ADHD and LI
•
ADHD has also been one of the most frequently reported co-occurring
neurodevelopmental disorders in study samples of children with language
impairments (LI) (e.g. Beitchman, Hood, & Inglis, 1990; Benasich, Curtiss,
& Tallal, 1993; Lindsay, Dockrell, & Strand, 2007; St. Clair, Pickles, Durkin,
& Conti-Ramsden, 2011; Willinger et al., 2003)….

•
… although the literature provides some discrepant findings with the extent
to which co-occurrence rates have exceeded expectations based on general
population estimates (cf. Lindsay & Dockrell, 2008; Redmond & Rice, 2002;
Rescorla, Ross, & McClure, 2007; Whitehouse, Robinson, & Zubrick, 2011).
