Attention-deficit hyperactivity disorder (ADHD) is a common
disorder in children that frequently persists into adulthood.
Studies have found that substance use disorders (SUD) are seen
more commonly in those with ADHD than the general population.
Although treatment with stimulant medications has been shown to
be effective for individuals with ADHD, concern about the use of
these agents in this population persists. This review article
highlights the research in this area with a focus on the
treatment of individuals who present with concomitant ADHD and
SUD. Although stimulants can be abused, studies have shown that
adolescents who are prescribed stimulants for ADHD have lower
rates of SUD than those who are not treated with stimulants. It
may be particularly difficult to evaluate adults for the
diagnosis of ADHD when SUD is a co-morbid factor. Studies show
that 20--30% of adults presenting with SUD have concomitant ADHD
and approximately 20--40% of adults with ADHD have histories of
SUD. Therefore, it is critical to perform careful diagnostic
interviews to discern if patients have either or both of these
disorders. Many clinical experts suggest that adults with ADHD
and active SUD be treated for the SUD until a period of sobriety
persists prior to initiation of specific treatment for ADHD.
Since individuals with ADHD and active SUD are more likely to
have more severe SUD and a worse prognosis, this approach may
not serve many patients, as they relapse prior to obtaining ADHD
treatment. Therefore, research has been directed towards
determining if the treatment of ADHD with stimulant medications
can be safe and effective for the individual with active SUD and
concomitant ADHD. An initial trial of methylphenidate in a
population of adults with active cocaine dependence and ADHD
indicates that this is the case. Individuals with ADHD and SUD
can present difficult diagnostic and therapeutic challenges. It
appears that the most effective treatment option is to create a
programme that uses the most effective treatment modalities
available, including both behavioural and medical therapies,
along with close supervision and monitoring. Newer medical
treatment options of long-acting stimulants and non-stimulants
(e.g. atomoxetine) offer effective treatment with a lower risk
of abuse potential.
