Many addicted individuals in Willisville, Illinois who end up in drug rehab are dual diagnosis clients with co-occurring mental and substance abuse problems. Surprisingly, as many as 1/3 of those who suffer with mental health issues in Willisville, Illinois also take part in substance abuse at some time 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 condition. 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 brought to light. This alone can help resolve addiction issues and put the individual in a position to receive treatment for both disorders so that they have a good chance of remaining abstinent and psychologically healthy in the future.
