ADDCoach4u: Up to 45% of Prisoners Have ADHD Studies Show

VANCOUVER, BRITISH COLUMBIA--(Marketwire - April 28, 2011) - We screen prisoners entering jail for physical health conditions. Why don't we screen them for mental health conditions like ADHD?

Up to 45% of prisoners have Attention Deficit Hyperactivity Disorder (ADHD) compared to 5% of adults with ADHD in the population. The UK screens prisoners for ADHD, shouldn't Canada do so too?

These findings come from a survey of 15 studies in peer reviewed journals done by Canadian Adult ADHD coach Pete Quily.

40% of adult male long term inmates in one study had ADHD.

45% of young males in jail in one study had ADHD.

If ADHD is ignored, there are higher rates of developing other conditions such as oppositional defiant disorder, conduct disorder, antisocial personality disorder, depression and anxiety disorders, that increase the risk of criminal behaviour.

"Many Canadian medical professionals have no training on ADHD", said Quily, "that, combined with the heavy stigma, leaves many ADHD adults undiagnosed, untreated, and vulnerable to self medication with alcohol, drugs, gambling, and crime."

"Evidence suggests that proper treatment (for ADHD) may reduce the risk for criminal behavior and the rate of recidivism among afflicted criminals."
