Co-Occurring disorders are present when there are two or more disorders at the same moment and these disorders were also called dual diagnosis or dual disorder. For example, an individual may suffer from bipolar disorder as well as substance abuse.
While the scope of treatment for drug dependency and mental conditions has emerged to be rather specific, the same thing goes as well for the terms used to refer to individuals who both have problems with drug dependency and mental conditions.
The two terms dual diagnosis and dual disorder are replaced by the term, co-occurring disorders. The terms being replaced may be misleading as they also refer to mental disorders and mental retardation occurring together in addition to their popular reference to a combination of substance abuse and mental disorders.
The terms are also misleading in that they only cover two disorders occurring at the same time which is not the case as two or more can occur at the same time. People who have co-occurring disorders also referred to as COD, often have at least one mental disorder and at least one disorder springing from alcohol or substance abuse as well. A diagnosis of co-occurring disorders is caused when at least one disorder of each type can be managed independent of the other and is not the simple bunch of symptoms resulting from the on disorder.
For the purposes of this article, we will use the dual disorders term interchangeably even if the co-occurring disorder is the most current term used professionally.
Mentally Ill Chemical Abusers in which the acronym MICA is derived from is sometimes used to describe individuals who have co-existing conditions and an evidently serious and stubborn mental condition like bipolar disorder and schizophrenia. A preferred definition is mentally ill chemically affected people since their condition is better described by the word affected and is not derogatory. Some of the other acronyms are: CAMI (chemical abuse and mental illness), MISU (mentally ill substance using), MISA (mentally ill substance abusers), SAMI (substance abuse and mental illness), ICO PSD (individuals with co-occurring psychiatric and substance disorders) and MIC'D (mentally ill chemically dependent).
Some common types of co-existing conditions consist of the combinations of major depression types associated with cocaine dependency, alcohol dependency along with panic disorder, extreme alcoholism along with polydrug abuse with schizophrenia and as well as borderline personality condition with sporadic polydrug misuse. Whilst the theme of this relates to dual disorders, a few patients suffer from three or even more disorders. Multiple disorders go by the same rules that apply to dual disorders.
The existence of combined co-existing conditions and those of psychiatric disorders can differ in several significant aspects like chronicity, gravity, disability and level of impairment in bodily operations. For instance, in the event if having two disorders, one may be either serious or mild or that one may be more serious than the other. However, with time, the extremity of both disorders might change. Degree of disability and weakening of bodily functions can as well differ.
Therefore, no single combination of dual disorders exists and there's indeed significant lack of consistency amongst these disorders. Specific treatment environments are, however, set up for patients that have alike combinations of dual disorders.
Over half of adult individuals having serious mental illness also have drug use disorders which can come in the form of misuse or dependency associated with the use of alcohol and drugs.
Compared patients who have a COD use problem alone or a mental health disorder, and more serious and chronic medical, social and emotional problems are often experienced by the patients with dual disorders. As they suffer from two disorders, they're at risk of a co-occurring disorder relapse and their mental disorder could also worsen. Also, a cycle is likely where once there is a relapse in addiction recovery, the patient becomes more prone to a psychiatric worsening which makes it much easier to relapse into an addiction. That means that patients with co-occurring disorders require a specific relapse prevention plan. Unlike patients who only have one disorder, those with dual disorders would mostly need prolonged treatment, have more difficulties and have slow progress in treatment.
Mental disorders that are most common amongst dually diagnosed people are personality disorders, mood disorders, psychotic disorders and mood disorders.
