Many addicted individuals in Forest Park, Illinois who find their way to drug rehab are dual diagnosis clients with co-occurring mental and substance abuse problems. In fact, as many as 1/3 of those who suffer with mental health issues in Forest Park, Illinois also become involved in substance abuse at some time in their lives. These dual diagnosis clients typically turn to drugs or alcohol to self medicate as a way to relieve the symptoms of an underlying psychiatric issue. Some addicted individuals aren't even diagnosed with a disorder, and only when they make it to a drug treatment center is this sort of issue uncovered. This in itself can sometimes help resolve addiction issues and put the individual in a position to receive treatment for both disorders so that they have a strong chance of remaining abstinent and psychologically stable in the future.
