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.
Just like the area of treatment for drug use and psychological disorders has developed to become more exact, the terminology that is employed to describe people who suffer both from psychological disorders and drug use has also become more precise.
The term co-occurring actually takes the place of the terms dual disorder and dual diagnosis. Even though the terms dual diagnosis and dual disorder are used regularly to refer to the combination of psychological disorders and drug use, these terms are misleading as they can also refer to other combinations of disorders like mental retardation and psychological disorders.
Additionally, the terminology may denote of the occurrence of just two disorders simultaneously when as a matter of fact there could be others, too. 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. In order to get a co-occurring diagnosis, at least one disorder of each type has to be established and traced to be independent and not just a combination of symptoms springing from one disorder but manifesting as independent.
In this article, the term dual disorders will also be used, even though the term co-occurring disorders is currently utilized among professionals.

The acronym MICA, which constitutes the phrase Mentally ILL Chemical Abusers, is eventually used to nominate people who have a COD and markedly serious and continued mental disorder like bipolar disorder or schizophrenia. A preferred definition is mentally ill chemically affected people since their condition is better described by the word affected and is not derogatory. Other acronyms are: ICOPS (individuals with co-occurring psychiatric and substance disorders), SAMI (substance abuse and mental illness), MIC'D (mentally ill chemically dependent) CAMI (chemical abuse and mental illness), MISU (mentally ill substance using), and MISA (mentally ill substance abusers).
Common examples of co-occurring disorders include the combinations of alcohol addiction with panic disorder, major depression with cocaine addiction, borderline personality disorder with episodic polydrug abuse, and alcoholism and polydrug addiction with schizophrenia. Whilst the theme of this relates to dual disorders, a few patients suffer from three or even more disorders. Multiple disorders are usually based on the same principles that can be used when talking about 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. As an example, both disorders can be mild or serious or one disorder can be more serious than the other disorder. How severe the disorders are also varies with time and is not constant. Other factors that may also vary include the level or degree of disability or impairment in day to day functions.
That means that, in fact, there are many differentiations among co-occurring disorders, not just one combination. 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.
Patients that have co-occurring disorders commonly feel stronger and chronic medical, emotional and social issues compared to those that only have a mental disorder or COD without the other. As they suffer from two disorders, they're at risk of a co-occurring disorder relapse and their mental disorder could also worsen. What's more, an addiction relapse frequently results in psychiatric decompensation and when mental problems worsen it frequently results in addiction relapse. Therefore, the treatment of relapses should be specifically designed for those with dual disorders. 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.
Personality, psychotic and mood disorders are among some of the most prevalent psychiatric disorders diagnosed in dual patient disorders.
