The cost of untreated Adult ADHD has shown to have a significant economic impact on society. Employers incur much larger expenses due to lost productivity, absenteeism, and increased health care costs due to coexisting medical conditions. Despite these huge economic losses, employers are still unaware how pervasive ADHD is in the adult population. In the U.S. approximately 4% of adults have ADHD yet less than 20% have been diagnosed or treated.  With growing awareness and continuing research, it will be incumbent on employers to address the issues Adult ADHD brings to the workplace. The projected lower growth of the labor force due to shifts in population demographics will present new challenges in filling their needs.  Employers will need effective strategies to attract creative talent. The logical approach for employers is to seek help in managing employees with ADHD to ensure each member of their team is able to contribute to the organizations success.
