Many addicted individuals in Vernon Hills, IL. who find their way to drug rehab are dual diagnosis clients with co-occurring mental and substance abuse problems. Actually, as many as 1/3 of those who suffer with mental health issues in Vernon Hills also become involved in substance abuse at some point in their lives. These dual diagnosis clients frequently turn to alcohol or drugs to self medicate as a way to relieve the symptoms of an underlying psychiatric issue. Some addicts aren't even diagnosed with a psychological condition, and only when they make it to a drug rehab program is this sort of issue brought to light. This alone can sometimes help resolve addiction issues and put the person in a position to receive treatment for both disorders so that they have a strong chance of remaining clean and sober and mentally healthy in the future.
