Results suggest there is moderate-to-high-level evidence that combined pharmacological and behavioral interventions , and pharmacological interventions alone can be effective in managing the core ADHD symptoms and academic performance at 14 months .
However , the effect size may decrease beyond this period .
This review has highlighted the paucity and limitations of the evidence investigating the long-term outcomes of recommended interventions for managing ADHD symptoms .
There is little evidence to suggest that the effects observed over the relatively short term are maintained throughout longer periods of impairment .
PURPOSE To systematic ally identify and review the currently available evidence on the long-term outcomes of recommended attention-deficit hyperactivity disorder ( ADHD ) interventions following r and omized controlled trials with children and young people .
Long-Term Follow-Up of Children with Mental Retardation/Borderline Intellectual Functioning and ADHD
Fifty-two children ( ages 7 to 14 years ) with moderate mental retardation to borderline intellectual functioning were recontacted 12 to 65 months following participation in a double-blind , placebo-controlled trial of methylpheni date ( MPH ) . Sixty-nine percent of subjects continued to be prescribed medication for behavior control at follow-up . While 72 % of the sample evidence d improvement , over two-thirds continued to be rated at or above the 98th percentile on the Hyperactivity Index of the Parent Conners . In fact , 22 % of subjects had received inpatient psychiatric treatment between the time of the initial MPH trial and follow-up . Finally , subjects with high initial ratings on the Parent Conners Conduct Problems scale were more likely to be suspended from school or receive inpatient psychiatric treatment than subjects with low initial ratings . The results suggested that children with ADHD and mental retardation or borderline intellectual functioning continued to exhibit significant symptoms associated with attention deficit hyperactivity disorder ( ADHD ) at follow-up and that early conduct problems were predictive of continuing behavioral difficulties
