Many people in Shelbyville, IL. who find their way to drug rehab are dual diagnosis clients with co-occurring mental and substance abuse problems. In fact, as many as 1/3 of those who suffer with mental health issues in Shelbyville also become involved in substance abuse at some point in their lives. These dual diagnosis clients frequently turn to drugs or alcohol to self medicate in an attempt to ease the symptoms of an underlying psychiatric condition. Some treatment clients aren't even diagnosed with a disorder, and only when they begin to receive treatment at a drug rehabilitation program is this sort of issue uncovered. This in itself can sometimes help resolve addiction issues and put the person in a position to receive treatment for both disorders so that they have a good chance of remaining clean and sober and mentally healthy in the future.
