Many individuals in Addison, 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 Addison also become involved 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 relieve the symptoms of an underlying psychiatric disorder. Some addicted individuals aren't even diagnosed with a psychological condition, and only when they make it to a drug rehab facility is this sort of psychological condition uncovered. This alone can help resolve addiction issues and put the individual in a position to get treatment for both conditions so that they have a strong chance of remaining clean and sober and mentally stable in the future.
