Russel Barkley, author of the book, "ADHD in Adults: What the Science Says," reports a higher proportion of adults with ADHD face utilities being turned off for non-payment, poor credit ratings and a lack of retirement savings.

The findings also show adults with ADHD have a higher percentage with anti-social behavior problems such as stealing and they are more likely to be put in jail than adults without the disorder, Barkley said.

"This educational initiative is meant to provide information about ADHD in adults, including the results of recent studies ... concerning their symptoms, impairments and functionality in many domains of life that support the results of previous research in this area," Barkley said in a statement.

Barkley says studies show those with ADHD are twice as likely to have problems keeping friends, three times more likely to be unemployed and four times more likely to have contracted a sexually transmitted disease. But Barkley says there "is hope for adults with ADHD" because there are ways to manage this chronic condition.
