What is dual diagnosis? How does dual diagnosis treatment help you with your recovery? Dual diagnosis treats both drug use and any underlying mental health issues that come along with it. To avoid relapsing or struggling with those mental health issues further, it's important that both aspects are dealt with before treatment is ended. Ending treatment of either of these two conditions make it more likely for relapse down the road. Dual diagnosis is one of the most important programs that treatment centers offer today.
