Many addicted individuals in Clarendon Hills, Illinois 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 Clarendon Hills also take part in substance abuse at some point in their lives. These dual diagnosis clients frequently turn to alcohol or drugs to self medicate in an attempt to ease the symptoms of an underlying psychological issue. Some treatment clients aren't even diagnosed with a disorder, and only when they begin to receive treatment at a drug treatment program is this sort of issue discovered. This alone can help resolve addiction issues and put the person in a position to get rehabilitation for both conditions so that they have a good chance of remaining clean and sober and psychologically stable in the future.
