Many people in Libertyville, Illinois who find their way to 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 Libertyville also take part in substance abuse at some time in their lives. These dual diagnosis clients typically turn to alcohol or drugs to self medicate as a way to alleviate the symptoms of an underlying psychological disorder. Some addicts aren't even diagnosed with a psychological condition, and only when they make it to a drug rehabilitation facility is this sort of issue uncovered. 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.
