Many addicted individuals in Williams, 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 Williams 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 ease the symptoms of an underlying psychological disorder. Some addicts aren't even diagnosed with a psychological condition, and only when they begin to receive treatment at a drug rehabilitation program is this sort of psychological condition discovered. This alone can sometimes help resolve addiction issues and put the person in a position to receive rehabilitation for both disorders so that they have a good chance of remaining abstinent and mentally healthy in the future.
