Dual Diagnosis

Dual Diagnosis

Dual diagnosis occurs when someone has both a mental disorder and an alcohol or drug problem. These conditions occur together frequently.

There are several possible relationships between Alcohol and Other Drugs (AODs) use and psychiatric symptoms and disorders. AODs may induce, worsen, or diminish psychiatric symptoms, complicating the diagnostic process.

The primary relationships between AOD use and psychiatric symptoms or disorders are described in the following classification model (Landry et al., 1991a; Lehman et al., 1989; Meyer, 1986). All of these possible relationships must be considered during the screening and assessment process.

AOD use can cause psychiatric symptoms and mimic psychiatric disorders. Acute and chronic AOD use can cause symptoms associated with almost any psychiatric disorder. The type, duration, and severity of these symptoms are usually related to the type, dose, and chronicity of the AOD use.

Acute and chronic AOD use can prompt the development, provoke the reemergence, or worsen the severity of psychiatric disorders.

AOD use can mask psychiatric symptoms and disorders. Individuals may use AODs to purposely dampen unwanted psychiatric symptoms and to ameliorate the unwanted side effects of medications. AOD use may inadvertently hide or change the character of psychiatric symptoms and disorders.

AOD withdrawal can cause psychiatric symptoms and mimic psychiatric syndromes. Cessation of AOD use following the development of tolerance and physical dependence causes an abstinence phenomenon with clusters of psychiatric symptoms that can also resemble psychiatric disorders.

Psychiatric and AOD disorders can coexist. One disorder may prompt the emergence of the other, or the two disorders may exist independently. Determining whether the disorders are related may be difficult, and may not be of great significance, when a patient has long-standing, combined disorders. Consider a 32-year-old patient with bipolar disorder whose first symptoms of alcohol abuse and mania started at age 18, who continues to experience alcoholism in addition to manic and depressive episodes. At this point, the patient has two well-developed independent disorders that both require treatment.

Psychiatric behaviors can mimic behaviors associated with AOD problems. Dysfunctional and maladaptive behaviors that are consistent with AOD abuse and addiction may have other causes, such as psychiatric, emotional, or social problems. Multidisciplinary assessment tools, drug testing, and information from family members are critical to confirm AOD disorders.

The symptoms of a coexisting psychiatric disorder may be misinterpreted as poor or incomplete “recovery” from AOD addiction. Psychiatric disorders may interfere with patients’ ability and motivation to participate in addiction treatment, as well as their compliance with treatment guidelines.

For example, patients with anxiety and phobias may fear and resist attending Alcoholics Anonymous or group meetings. Depressed people may be too unmotivated and lethargic to participate in treatment. Patients with psychotic or manic symptoms may exhibit bizarre behavior and poor interpersonal relations during treatment, especially during group-oriented activities. Such behaviors may be misinterpreted as signs of treatment resistance or symptoms of addiction relapse.
