Many addicted individuals in Derby, Iowa who end up in 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 Derby also become involved in substance abuse at some point in their lives. These dual diagnosis clients typically turn to alcohol or drugs to self medicate in an attempt to alleviate the symptoms of an underlying psychological disorder. Some addicted individuals aren't even diagnosed with a disorder, and only when they begin to receive treatment at a drug rehab center is this sort of issue brought to light. This alone can sometimes 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 psychologically stable in the future.
