These observational studies also showed positive correlations between early recognition of the disorder , stimulant treatment during childhood and favorable long-term outcome in adult ADHD patients .
In conclusion , stimulant therapy of ADHD has long-term beneficial effects and is well tolerated .
Attention-deficit/hyperactivity disorder ( ADHD ) is a common disorder of childhood that often persists into adulthood .
Although stimulant medications are recommended as the first-line treatment for ADHD because of their documented short-term effects in children and adults , less is known about their effects on long-term outcome in adults .
Here we review the long-term efficacy and safety of the stimulant drugs methylpheni date and amphetamine , as well as the related compound atomoxetine .
We performed a systematic review to identify direct and indirect effects of stimulant therapy on long-term outcome in adults .
A Systematic Review of Global Publication Trends Regarding Long-Term Outcomes of ADHD
There is increased global recognition of attention deficit hyperactivity disorder ( ADHD ) as a serious medical condition with long-term consequences . Although originally conceived of as a childhood disorder , ADHD is being increasingly recognized in adults . Individual geographic regions may have specific interests and objectives for the study of ADHD . A systematic review of  long-term outcomes ( LTOs ) in ADHD was conducted to evaluate research on ADHD LTOs  on a global scale . Studies that were at least 2 years in duration were examined . A total of 351 studies were identified in the final analysis . We identified nine outcomes of interest and classified studies by specific geographical regions , age groups studied and study design by region and over time . Published studies of LTOs in ADHD have increased in all geographical regions over the past three decades , with a peak number of 42 publications in 2008 . This rise in publications on ADHD LTOs may reflect a rise in global interest and recognition of consequences and impairment associated with ADHD . Although many world regions have published on ADHD LTOs , the majority of studies have emerged from the US and Canada , followed by Europe . While investigators in the US and Canada were predominantly interested in drug addiction as a LTO , European research ers were more interested in antisocial behavior , and Eastern Asian investigators focused on both of these LTOs as well as self-esteem . Geographical differences in the focus of ADHD LTO studies may reflect regional variations in cultural values . Proportionally fewer prospect i ve longitudinal studies and proportionally more retrospective and cross-sectional studies have been published in more recent decades . Finally , more studies focusing on ADHD in adolescents and adults have been conducted in recent years , and particularly adolescents in Eastern Asia . These changes in basic study design may reflect an increase in the recognition that ADHD is a lifetime chronic disorder . This systematic review analysis of publication trends in ADHD LTOs reflects geographically based interests that change over time
