Many people in Osterdock, Iowa 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 Osterdock also take part in substance abuse at some point in their lives. These dual diagnosis clients typically turn to alcohol or drugs to self medicate as a way to alleviate the symptoms of an underlying psychological condition. Some treatment clients aren't even diagnosed with a disorder, and only when they make it to a drug treatment program is this sort of psychological condition uncovered. 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 good chance of remaining abstinent and mentally stable in the future.
