Many addicted individuals in Oak Park, IL. who end up in drug rehab are dual diagnosis clients with co-occurring mental and substance abuse problems. In fact, as many as 1/3 of those who struggle with mental health issues in Oak Park 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 psychiatric condition. Some treatment clients aren't even diagnosed with a psychological condition, and only when they make it to a drug rehab program is this sort of psychological condition discovered. This alone can help resolve addiction issues and put the person in a position to get rehabilitation for both disorders so that they have a strong chance of remaining abstinent and mentally stable in the future.
