Masked depression

Masked depression (MD) was a proposed form of atypical depression[1] in which somatic symptoms or behavioural disturbances dominate the clinical picture and disguise the underlying affective disorder.[2] The concept is not currently supported by the mental health profession.[3]

Clinical manifestations

Somatic manifestations of MD are distinguished by an extreme diversity[4]:110 and include headaches, back pain, abdominal pain etc. Pathological behaviour masking depression may take the form of compulsive gambling, compulsive work, changes in arousal or orgasmic function, decreased libido or, on the contrary, impulsive sexual behaviour, alcoholism, or drug addiction.

Dispute about the concept

MD has been variously described as "depression sine (without) depression" (K. Schneider, 1925), "latent" depression (Lange J., 1928), "vegetative depression" (R. Lemke, 1949[5]) "hidden" or "masked" depression (Lopez Ibor J.J., 1972;[6] Kielholz J.J., 1983; Pichot P.; Hasson J., 1973), "larvate" or "somatisation depression" (Gayral L., 1972), "depressive equivalents" etc.[7] Most investigators, especially those in the German-speaking countries, assumed masked depression (German: die larvierte Depression[8]) to be endogenous depression.[9] The term was largely used in the 1970s and 1980s, but at the end of the 20th century there was a decline in interest in the study of masked depression. Today this diagnosis does not play a significant clinical or scientific role.[10]

Epidemiology

MD is supposed to be a common clinical phenomenon.[11] According to some authors, masked depression is as frequent as overt depression.[12] Although masked depression can be found at any age, it has been observed more commonly after mid-life.[12]

Making the diagnosis and the management of MD in clinical practice are complicated by the fact that he who has got MD is unaware of his mental illness. Patients with MD are reluctant to associate their physical symptoms with an affective disorder[13] and refuse mental health care. As a rule, these patients attribute their disturbances to physical illness, seek medical care for them, and report only somatic complaints to their physicians,[14] with the consequence that many of such depressions are not recognized or are misdiagnosed and mistreated[11] Estimates of depressed patients who are correctly identified and treated range from 5% to 60%.[15] Recent data show that about 10% of people who consult a physician for any reason originally suffer from affective disorders disguised by physical symptoms.[12][16]

Official diagnostic status

Current classifications: ICD-10 and DSM-IV do not contain the term "masked depression".[1] Some Ukrainian psychiatrists claim that MD is to be qualified as "depression with somatic symptoms" (F 3x.01), according to ICD-10.[17]

Diagnostic criteria

Affective disorders in patients with MD can only be detected by means of a clinician-administered diagnostic interview.[4]:408[18]:576[19] Organic exclusion rules[19] and other criteria are used in making the diagnosis of MD.[20]:185–188
