Dual diagnosis can be a situation in which two independent disorders are present, and most often describes a co-occurring drug or alcohol use and mental health disorder. A dual diagnosis might help someone who might possibly not have been able to be helped in the past, end substance abuse because they can be accurately diagnosed and helped. Their mental health disorder could have been misdiagnosed, undiagnosed, or treated incorrectly which could have triggered and resulted in their drug or alcohol use issues. Establishing the truth that someone is in fact a dual diagnosis client not just helps establish an effective course of treatment for them, but will also help clients better understand what caused their drug abuse and ways to prevent it down the road. Addressing dual diagnosis may be a more extensive process than the usual typical drug rehab program, and people who have a dual diagnosis might be required to take part in a substantial aftercare program which can include appropriate medical support in addition to continued rehab services. Being clinically determined to have co-occurring disorders doesn't imply the person must be medicated through out their lives either, and in fact many people who have a dual diagnosis experience far better results when treated holistically and when alternative therapy is employed.
