What Is This

What Is Dual diagnosis drug rehab?

Dual diagnosis — also called co-occurring disorders — refers to the simultaneous presence of a substance use disorder and one or more mental health conditions such as depression, anxiety, PTSD, bipolar disorder, or schizophrenia. According to SAMHSA's 2022 National Survey on Drug Use and Health, over 21 million Americans have a co-occurring substance use and mental health disorder.

Treating addiction without addressing the underlying mental health condition is one of the primary reasons people relapse. Integrated dual diagnosis treatment — where both conditions are treated simultaneously by the same clinical team — produces dramatically better outcomes than treating each condition separately. Illinois has 393+ dual diagnosis programs staffed by addiction specialists and licensed mental health professionals.

Call (866) 720-3784 to find an integrated dual diagnosis program in Illinois that accepts your insurance. Our specialists can assess your needs and identify programs equipped to treat both conditions.
