Many individuals in Machesney Park, 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 struggle with mental health issues in Machesney Park 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 as a way to relieve the symptoms of an underlying psychological disorder. Some treatment clients aren't even diagnosed with a disorder, and only when they begin to receive treatment at a drug rehab program is this sort of issue discovered. 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 clean and sober and mentally stable in the future.
