Many addicted individuals in Lake Zurich, IL. 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 Lake Zurich also take part 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 ease the symptoms of an underlying psychological condition. Some addicts aren't even diagnosed with a psychological condition, and only when they begin to receive treatment at a drug rehabilitation facility is this sort of issue brought to light. This in itself can sometimes help resolve addiction issues and put the individual in a position to get treatment for both conditions so that they have a good chance of remaining abstinent and mentally healthy in the future.
