Many addicted individuals in Hanover 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 Hanover, Illinois also take part in substance abuse at some point in their lives. These dual diagnosis clients frequently turn to alcohol or drugs to self medicate in an attempt to alleviate the symptoms of an underlying psychiatric disorder. Some treatment clients aren't even diagnosed with a disorder, and only when they begin to receive treatment at a drug rehab center is this sort of psychological condition brought to light. This alone can sometimes help resolve addiction issues and put the individual in a position to receive treatment for both conditions so that they have a good chance of remaining clean and sober and psychologically stable in the future.
