Many addicted individuals in Buffalo Grove, 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 Buffalo Grove, Illinois also become involved in substance abuse at some point in their lives. These dual diagnosis clients often turn to drugs or alcohol to self medicate in an attempt to relieve the symptoms of an underlying psychiatric disorder. Some addicted individuals aren't even diagnosed with a disorder, and only when they make it to a drug rehabilitation program is this sort of issue uncovered.
