Co-Occurring Disorders during-rehab


Co-Occurring Disorders Formerly was known as the dual disorder or dual diagnosis, co-occurring disorders explain the existence of two or more disorders at the same time. For instance, an individual can go through substance dependency while having bipolar disorder, too.

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 two terms dual diagnosis and dual disorder are replaced by the term, co-occurring disorders. Even though these replaced terms have usually been used when discussing a mix of mental disorders and substance abuse, they are also referring to other combinations of disorders (like mental disorders and mental retardation), which can sometimes cause confusion.

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 suffer from co-occurring disorders (COD) have one or more disorders that have to do with mental disorders and one or more disorders that have to do with the use of drugs and/or alcohol. When a minimum of one disorder of both types can be confirmed which isn't dependent on the other, we can talk about diagnosing co-occurring disorders and it isn't just a bunch of symptoms that are caused by just one disorder.

Dual disorder is used interchangeably in this article to refer to co-occurring disorders although the latter is the most recent development in the lingo as used in the medical field.

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. Other acronyms include SAMI (Substance abuse and mental illness), MISA (mentally ill substance abusers), MISU (mentally ill substance using), CAMI (chemical abuse and mental illness), ICO PSD (individuals with co-occurring psychiatric and substance disorders) and MIC'D (mentally ill chemically dependent).

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. Some patients have more than two disorders even if the focus of this is on dual disorders. Multiple disorders go by the same rules that apply to dual disorders.

The severity, degree of impairment in functioning, chronicity and disability are some of the factors that differ in the occurrence of combinations of psychiatric disorders alongside substance abuse problems. For instance, each of the two disorders may be serious or mild, or one may be more serious than the other. Truly, the seriousness of both disorders can be modified eventually. Degrees of impairment in functioning as well as disability can also change.

Therefore, it is important to note that there is no single combination of co-occurring disorders; they actually vary depending on the mentioned factors. Although patients with the same combination of dual disorders most of the time are met in some treatment programmes.


More than half of all adults with serious mental illness are further caused by substance use disorders (abuse or addiction related to alcohol or other 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. They are vulnerable to both COD relapse and a worsening of the psychiatric disorder because they have two disorders. What's more, an addiction relapse frequently results in psychiatric decompensation and when mental problems worsen it frequently results in addiction relapse. That means that patients with co-occurring disorders require a specific relapse prevention plan. Patients who battle with dual disorders frequently need longer treatment, experience more emergencies and advance more slowly in treatment than patients who battle just a single disorder.

Psychiatric disorders most prevalent among dually diagnosed patients include personality disorders, mood disorders, psychotic disorders, and anxiety disorders.
