Many addicted individuals in Wilmette, 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 Wilmette, Illinois also take part in substance abuse at some point in their lives. These dual diagnosis clients typically turn to alcohol or drugs to self medicate as a way to ease the symptoms of an underlying psychological disorder. Some treatment clients 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 sometimes 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 abstinent and mentally stable in the future.
