Many addicted individuals in Highland Park, IL. who find their way to drug rehab are dual diagnosis clients with co-occurring mental and substance abuse problems. Surprisingly, as many as 1/3 of those who struggle with mental health issues in Highland Park also take part in substance abuse at some time in their lives. These dual diagnosis clients typically turn to drugs or alcohol to self medicate as a way to ease the symptoms of an underlying psychiatric disorder. Some addicted individuals aren't even diagnosed with a disorder, and only when they begin to receive treatment at a drug rehabilitation facility is this sort of issue brought to light. This in itself can help resolve addiction issues and put the individual in a position to receive rehabilitation for both conditions so that they have a good chance of remaining clean and sober and mentally healthy in the future.
