Many people in Greenville, Iowa 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 Greenville, Iowa also take part in substance abuse at some time in their lives. These dual diagnosis clients frequently turn to alcohol or drugs to self medicate in an attempt to alleviate the symptoms of an underlying psychiatric condition. Some addicts aren't even diagnosed with a disorder, and only when they begin to receive treatment at a drug rehab program is this sort of psychological condition uncovered. This in itself 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 mentally stable in the future.
