Many people in Island Lake, IL. 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 Island Lake 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 in an attempt to ease the symptoms of an underlying psychiatric issue. Some addicts aren't even diagnosed with a psychological condition, and only when they begin to receive treatment at a drug rehabilitation program is this sort of issue brought to light. This alone can help resolve addiction issues and put the individual in a position to get rehabilitation for both conditions so that they have a good chance of remaining abstinent and mentally stable in the future.
