There is very-low- quality evidence that clonidine has a small effect on oppositional behaviour and conduct problems in youth with ADHD , with and without ODD or CD .
There is moderate- quality evidence that guanfacine has a small-to-moderate effect on oppositional behaviour in youth with ADHD , with and without ODD .
There is high- quality evidence that atomoxetine has a small effect on oppositional behaviour in youth with ADHD , with and without ODD or CD .
Conclusions : Evidence indicates that psychostimulants , alpha-2 agonists , and atomoxetine can be beneficial for disruptive and aggressive behaviours in addition to core ADHD symptoms ; however , psychostimulants generally provide the most benefit
Objective : Children with attention-deficit hyperactivity disorder ( ADHD ) may have oppositional behaviour , conduct problems , and aggression .
These symptoms vary in severity , and may be related to a comorbid diagnosis of oppositional defiant disorder ( ODD ) or conduct disorder ( CD ) .
Critical evaluation of the efficacy of ADHD medications may guide the clinician regarding the usefulness of medications for these symptoms .
Treatment of ADHD in children with tics: A randomized controlled trial
Background The treatment of children with attention deficit hyperactivity disorder ( ADHD ) and Tourette syndrome ( TS ) has been problematic because methylpheni date (MPH)—the most commonly used drug to treat ADHD — has been reported to worsen tics and because clonidine (CLON)—the most commonly prescribed alternative — has unproven efficacy . Methods The authors conducted a multicenter , r and omized , double-blind clinical trial in which 136 children with ADHD and a chronic tic disorder were r and omly administered CLON alone , MPH alone , combined CLON + MPH , or placebo ( 2 × 2 factorial design ) . Each subject participated for 16 weeks ( weeks 1–4 CLON/placebo dose titration , weeks 5–8 added MPH/placebo dose titration , weeks 9–16 maintenance therapy ) . Results Thirty-seven children were administered MPH alone , 34 were administered CLON alone , 33 were administered CLON + MPH , and 32 were administered placebo . For our primary outcome measure of ADHD ( Conners Abbreviated Symptom Question naire – Teacher ) , significant improvement occurred for subjects assigned to CLON ( p < 0.002 ) and those assigned to MPH ( p < 0.003 ) . Compared with placebo , the greatest benefit occurred with combined CLON + MPH ( p < 0.0001 ) . CLON appeared to be most helpful for impulsivity and hyperactivity ; MPH appeared to be most helpful for inattention . The proportion of individual subjects reporting a worsening of tics as an adverse effect was no higher in those treated with MPH ( 20 % ) than those being administered CLON alone ( 26 % ) or placebo ( 22 % ) . Compared with placebo , measured tic severity lessened in all active treatment groups in the following order : CLON + MPH , CLON alone , MPH alone . Sedation was common with CLON treatment ( 28 % reported moderate or severe sedation ) , but otherwise the drugs were tolerated well , including absence of any evident cardiac toxicity . Conclusions Methylpheni date and clonidine ( particularly in combination ) are effective for ADHD in children with comorbid tics . Prior recommendations to avoid methylpheni date in these children because of concerns of worsening tics are unsupported by this trial
