TLDR
Whether the diagnosis of attention deficit hyperactivity disorder (ADHD) is retained from childhood into adulthood is assessed and the rate of ADHD in a given age group appears to decline by 50% approximately every 5 years.Abstract:
Objective : This study was undertaken to assess whether the diagnosis of attention deficit hyperactivity disorder (ADHD) is retained from childhood into adulthood. Method : A search of the literature yielded nine prospective studies in which cohorts of children with the disorder were formed and then reexamined 4-16 years later to determine the level of retained ADHD. The resulting data were subjected to nonlinear regression analysis to ascertain the relationship with chronological age. Results : The data followed an exponential decline over time to a high degree of accuracy. Conclusions : The rate of ADHD in a given age group appears to decline by 50% approximately every 5 years. If a prevalence of ADHD in childhood of 4% is assumed and the exponential decline extrapolated the estimated rate of adult ADHD ranges from about 0.8% at age 20 to 0.05% at age 40.read more

The age-dependent decline of attention deficit hyperactivity disorder: a meta-analysis of follow-up studies
TL;DR: The results show that estimates of ADHD's persistence rely heavily on how one defines persistence, yet, regardless of definition, the analyses show that evidence for ADHD lessens with age.

Age-Dependent Decline of Symptoms of Attention Deficit Hyperactivity Disorder: Impact of Remission Definition and Symptom Type
TL;DR: These results indicate that differences in reported remission rates reflect the definition used rather than the disorder's course, and provide systematic support for the clinical observation that hyperactivity and impulsivity symptoms tend to decline at a higher rate than inattention symptoms.

Prevalence and correlates of adult attention-deficit hyperactivity disorder: meta-analysis.
TL;DR: Prevalence of ADHD in adults declines with age in the general population and the unclear validity of DSM–IV diagnostic criteria for this condition can lead to reduced prevalence rates by underestimation of the prevalence of adult ADHD.

The persistence of attention-deficit/hyperactivity disorder into young adulthood as a function of reporting source and definition of disorder.
TL;DR: Recollections of childhood ADHD showed moderate correlations with actual parent ratings collected in childd hood, which suggests some validity for such recollections.

Diagnosis and Treatment of Attention-Deficit/Hyperactivity Disorder in Children and Adolescents
TL;DR: Although some children are being diagnosed as having ADHD with insufficient evaluation and in some cases stimulant medication is prescribed when treatment alternatives exist, there is little evidence of widespread overdiagnosis or misdiagnosis of ADHD or ofidespread overprescription of methylphenidate by physicians.
