Dual diagnosis can be a circumstance whereby two independent disorders exist, and most often describes a co-occurring drug or alcohol use and mental health disorder. A dual diagnosis might help an individual who might not have been capable of being helped previously, stop drug abuse because they can be accurately diagnosed and helped. Their mental health disorder may have been misdiagnosed, undiagnosed, or mistreated which may have prompted and resulted in their drug or alcohol use problems. Establishing the truth that someone is actually a dual diagnosis client not merely helps establish an efficient course of treatment for them, but may also help clients better determine what led to their drug use and how to prevent it down the road. Handling dual diagnosis might be a more extensive process compared to a typical drug rehab program, and people who have a dual diagnosis might need to participate in a substantial aftercare program that might include appropriate medical support in addition to further rehabilitation services. Being identified as having co-occurring disorders doesn't imply the individual must be medicated for the rest of their lives either, and actually many individuals with a dual diagnosis experience much better results when treated holistically and when alternative treatment methods are employed.
