Attention-deficit/hyperactivity disorder (ADHD) is a common childhood disorder that can continue into adolescence and adulthood (Rowland et al., 2002; Visser et al., 2014). Symptoms include higher than normal levels of impulsivity and inattention that impair an individual's ability to function properly in various settings, such as school or work. In the published literature, studies show a greater number of boys being diagnosed with ADHD compared with girls, with male to female ratios reported to range from 3:1 to 9:1, dependent on the study setting, such as in the general population or clinics (Chhabildas et al., 2001). Some studies report the worldwide prevalence of ADHD to be between 5.29-7.1% in children and adolescents, and 3.4% in adults.
There are three distinct subtypes of ADHD identified in the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV): predominantly inattentive type (ADHD-I), predominantly hyperactive-impulsive type (ADHD-H), and combined type (ADHD-C) (Willcutt, 2012). Individuals with the ADHD-I subtype display symptoms that are best described by the inattentive category only, whereas individuals with ADHD-H display symptoms that are best described by the hyperactive-impulsive category only.
Epidemiologists forecast the diagnosed prevalent cases of ADHD in the 7MM to grow by 2.86% per year over the next 10 years, from 26,540,792 cases in 2014 to 34,129,001 cases in 2024. In the 7MM, the US will have the highest number of diagnosed prevalent cases throughout the forecast period, with 21,217,302 cases in 2014 and 28,833,163 cases in 2024. In the 7MM, the age group 18 years and older had the highest number of diagnosed prevalent cases of ADHD in 2014, contributing 18,870,635 cases, consisting of 71.10% of the total.
Across the 7MM, the diagnosed prevalent cases of ADHD are higher in men compared to women, with 17,153,298 (64.63%) cases occurring in men and 9,387,494 (35.37%) cases occurring in women in 2014. The ADHD subtype in children and adolescents with the highest number of diagnosed prevalent cases was ADHD-I, with 3,175,915 cases or 41.43% of the total in the 7MM in 2014, while the ADHD subtype in adults with the highest number of diagnosed prevalent cases was ADHD-C, with 10,770,130 cases or 57.07% of the total.
The report "EpiCast Report: Attention-Deficit/Hyperactivity Disorder - Epidemiology Forecast to 2024" provide an overview of the risk factors and global trends of MDD in the 7MM (US, France, Germany, Italy, Spain, UK, and Japan). It includes a 10-year epidemiology forecast of 12-month total prevalent cases of MDD segmented by age (18-19 years, in five-year increments from ages 20-84 years, and ending at ages 85 years and older), sex, and severity in these seven markets. Moreover, this report providing expert analysis of disease trends in the 7MM.
