U.S. household income losses due to attention-deficit/hyperactivity disorder (ADHD) total nearly $77 billion each year, "ADHD, a life-long disorder, may be one of the costliest medical conditions in the United States. "The same ADHD symptoms that may cause young patients to perform poorly in school or miss classes may also cause these patients, as adults, to lose a significant amount of income each year. The compelling results of this survey show that ADHD is a serious medical condition causing significant, life-long impairments. Evaluating, diagnosing and treating this condition may not only improve the quality of life, but may save adults with ADHD billions of dollars every year."
