While parallel treatment seems like a logical solution, it is rather ineffective. It can be difficult to determine which symptoms are associated with which problem. Now doctors recommend taking an integrative approach. Instead of having a team develop a treatment plan for the mental illness and a different team develop a treatment plan for the substance abuse, one team will take care of both disorders at the same time. With this type of treatment, one team will be able to observe and make adjustments to the treatment plan, It allows for a more complete treatment program that is more effective and has a better success rate. Having one treatment team also eliminates any miscommunication between doctors that could disrupt the treatment plan.
