Many people in Berwick, Illinois 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 struggle with mental health issues in Berwick also take part in substance abuse at some time in their lives. These dual diagnosis clients frequently turn to alcohol or drugs to self medicate as a way to alleviate the symptoms of an underlying psychiatric disorder. Some addicts aren't even diagnosed with a psychological condition, and only when they begin to receive treatment at a drug treatment center is this sort of psychological condition uncovered. This alone can help resolve addiction issues and put the individual in a position to get treatment for both disorders so that they have a good chance of remaining clean and sober and mentally stable in the future.
