Many people in Dennison who end up in 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 Dennison, IL. also become involved in substance abuse at some time in their lives. These dual diagnosis clients often turn to alcohol or drugs to self medicate as a way to relieve the symptoms of an underlying psychological issue. Some treatment clients aren't even diagnosed with a disorder, and only when they begin to receive treatment at a drug rehabilitation program is this sort of psychological condition discovered. This alone can sometimes help resolve addiction issues and put the person in a position to receive rehabilitation for both disorders so that they have a strong chance of remaining clean and sober and psychologically healthy in the future.
