European Psychiatry 26 (2011) 11-14 Diagnosis and classification of mental disorders in Russian speaking psychiatry: focus on affective spectrum disorders V.N. Krasnov Moscow Research Institute of Psychiatry, Poteshnaya 3, Moscow, 107076, Russia. ABSTRACT Keywords: Classification ICD-10 DSM-IV Psychopathology Dynamic approaches in diagnostics Psychopharmacological analysis Affective spectrum disorders Depression Anxiety PTSD Somatoform disorders Russian–speaking psychiatry The paper deals with present-day classification of mental disorders regarded from the positions of Russian-speaking psychiatrists. Consideration of depressive and anxiety disorders, in particular in the context of a multi-year research within the settings of the primary care network, points to close links between these disorders. The concept of a psychopathological commonality among affective spectrum disorders is set forth with references to earlier studies and the data of other Russianlanguage writers. The affective spectrum disorders cover typical affective disorders, mixed anxiety and depressive disorders, as well as somatoform and stress-related disorders. Current classifications ICD-10 and DSM-IV reflect many contradictory tendencies in recent developments in psychiatry. The principal among them are as follows: • necessity to use standard and internationally accepted diagnostic categories; • simplification of diagnosis reached by counting symptoms of disorder (operational diagnostics); • prevalent static evaluation of disorders, i.e. identifying an actual combination of symptoms at a certain moment of time, as a diagnostic unit, instead of dynamic evaluation of the syndrome. • the impact of public perception on the classification or name of disorders, the perception stemming from notorious bias or prejudice with regard to psychiatry. There have been some precedents when reciprocal striving of both psychiatrists and associations of patients and their relatives brought about radical suggestions of denying certain long-established medical diagnostic terms such as schizophrenia [1].

All rights reserved. generally accepted terminology is fraught with losing scientific landmarks in both psychiatry and medicine as a whole. The mentioned tendencies reflect utilitarian essence of the classification as a technological facet of psychiatric practice. And this is their difference as a consensus of experts from psychopathology as a theoretical and conceptual level of clinical analysis based on structural connections and dynamic interactions of mental phenomena (both abnormal and natural, including defensive and compensatory ones). To a certain degree one can hardly expect obligatory correspondence between the psychopathological (systemic) evaluation of some condition and establishing its place in the nomenclature of mental disorders recognized at concrete period of time. Though the majority of Russian and Russian-speaking psychiatrists in Belarus, the Ukraine, Kazakhstan, Kyrgyz Republic and Armenia do recognize the advantages of the ICD-10 as a common language for psychiatrists all over the world, they are rather critical about certain general and specific aspects of the ICD-10 and DSM-IV. They consider renunciation of nosology (as a basis for classification), as a temporary retreat necessary for review and analysis of data concerning etiology and pathogenesis of the majority of mental disorders. Atheoretical character of the ICD-10 and DSM-IV is presented as renunciation of ideology, while the 12 V.N. Krasnov / European Psychiatry 26 (2011) 11-14 nosological clinical system initially developed by E. Kraepelin [2] is considered as a variant of ideology. Actually, the nosological system was a means of learning about morbid phenomena using the knowledge, and data available in certain period of history. Russian-speaking psychiatrists educated in accordance with traditions of classical clinical psychiatry, primarily German, French and Russian, do not reject the nosological principle completely. They still hope that a new nosology will arise as a unity of etiology, symptomatology and the course of disease. Methodology of diagnosis implies the development of symptoms in time, grouping particular features, organizing them in systematic way, finding internal relationships between individual elements and observing the shaping of the syndrome. The syndrome is understood as a dynamic formation with changing structural ratios of symptoms. In an autochthonous, spontaneous development of a disease, some symptoms may come to foreground, some decrease or remain hidden, but still present. This is an essential characteristic of syndromokinesis, or syndrome trend. In the course of a relatively long-term observation and treatment the psychiatrist can observe the reshaping and transformation of syndromes. Psychopharmacological analysis, i.e. using medication both as a treatment factor and a means of investigation, offers an opportunity to study the psychopathological dynamics of the syndrome and specify the diagnosis [3,4]. Thus, use of antipsychotics (olanzapine, risperidon or other) in paranoid schizophrenia may help to detect underlying depression. In other cases, the use of antidepressants with a stimulating component for the treatment of depression can reveal incongruent delusional ideas (e.g. ideas of persecution) and thus cause alteration of diagnosis and adjustment of treatment. Another example could be relatively fast relief of seemingly dominant anxiety by means of antidepressant medication with anxiolytic properties (like trazodon, mianserin, mirtazapin), while the depressive “nucleus” lags behind and gradually decreases two to three weeks after the primary anxiolytic effect of the medication. Similar combined treatment and diagnostic approaches we can find not only in Russian clinical psychiatry [5]. Russian and Russian-speaking specialists still take efforts to confirm the single nature of depression and majority of anxiety disorders within frames of anxiety-depressive conditions despite their current separate positions in the ICD-10 and DSM-IV as depressive disorder and anxiety disorder. Close clinical relationships between anxiety and depression have been formulated in traditional psychiatry [6-8]. It is a well-known fact from psychiatric practice dealing with recurrent depression that in every next depressive episode the representation of anxiety components decreases while the representation of typically depressive ones (like diurnal variations with morning worsening, diminished motivation for activity, and feeling of guilt) increases. Clinically and epidemiologically the distinction between long-term anxiety disorders and major depression (specifically regarding first depressive episode) are not clear-cut [9-12]. Our special research of affective spectrum disorders in primary health care system in framework of the Programme “Recognition and treatment of depression in primary care” [13] also suggests transformation of anxiety disorders into depressive disorder within one continuum. Purpose was to study of the prevalence of affective spectrum disorders in primary care setting. Methods used are as follows: screening questionnaire, semistructured psychiatric interview, SCL-90-R, Hamilton Depression Rating Scale (HDRS-17), Hamilton Anxiety Rating Scale (HARS). In 2000–2001 a screening of affective spectrum disorders in several territorial (general medical) polyclinics in three cities of Russia has been carried out. Subjects of investigation were working or studying persons, aged from 18 to 55 years. During the first stage, we identified with the help of a 7-item screening instrument a group of outpatients with various affective spectrum disorders, including subthreshold depression, anxiety and somatoform (psychovegetative) disorders. This group consisted of 2.749 persons (51.2%) of the 5.366 outpatients screened. They were offered a consultation of a psychiatrist concerning their symptoms, in a special (so called “psychotherapeutic”) room. 1.919 (35.8%) agreed to this proposal and were interviewed by a psychiatrist. 1.616 (30.1%) cases of those investigated were diagnosed as suffering from depression according to ICD-10 criteria for a depressive episode; in 1.334 cases (24.8%) severity of depression was 15 or more on the Hamilton Depression Scale. Diagnoses distribution is presented in Table 1. In accordance with the terms of the above-mentioned Program, these persons could enter a 6-week course of medication with modern antidepressants, mainly with sertraline. In about 90% of these cases depression dominated in patients’ condition but it was accompanied by subsyndromal or obvious moderate anxiety disorders. At the same time, there were different combinations of depression with anxiety and somatoform disturbunces--with similar score levels of somatization, depression and anxiety by SCL-90-R. As for prevalent anxiety disorders (like generalized anxiety disorder or panic disorder), they were diagnosed only in 238 (4.4%) persons. Somatoform disorders were mostly preliminary diagnosed for further observation. In 2002-2003, a second screening with subsequent diagnostic procedure and following the same research design took place in two policlinics. Screening covered 4.020 persons, and 2.046 (50.9%) had signs of affective spectrum disorders. A psychiatric interview helped to detect 1178 (29.3%) cases of depression, including 992 cases (24.7%) with score 15 and higher on the Hamilton Depression Scale. 138 of the latter subgroup had previously been included in the sample of previous research in 2000 - 2001, and 34 of them then had been diagnosed as anxiety disorders, including 9 cases of “generalized anxiety disorder” (GAD), 19 cases of “panic disorders” and 6 other cases of anxiety disorders. At the period 2002-2003 the above mentioned cases met the criteria of depressive episode. Former dominated anxiety Table 1 ICD-10 diagnoses distribution of depressive disorders in primary care. F 32 Depressive episode 31.2% F 33 Recurrent depressive disorder 24.1% F 34 Chronic depressive disorder (mainly “double depression” within dysthymia) 26.3% F 41.2 Mixed anxiety and depressive disorder 11.0% F 43.21 Long-term depressive reaction 3.1% Others 4.3% V.N. Krasnov / European Psychiatry 26 (2011) 11-14 happened to be on subordinated position because of pronounced symptoms of depression. In 2004-2005 more 28 cases of anxiety disorders from observed sample have been changed for diagnosis “depression”, including 13 with former diagnosis GAD. Besides during the period of observation a part of patients with mixed anxiety and depressive disorder entered for secondary consultative aid, and their condition turned out more close to strict criteria of depression. It is noteworthy that the so-called social phobia was hardly considered as a basis for seeking help within primary care system. Separate somatoform disorders without (sub) depressive and anxiety features were also identified in rare cases. Thus, one can suggest a tendency for transformation of affective disorders in the course of time or subsequent episodes – from prevalent anxiety symptoms to mixed anxiety – depressive condition, and further on to depressive syndrome per se. It seems like another argument in favor of single pathogenetic entity for majority of affective spectrum disorders. Then anxiety shows at the initial stage or as the foreground primary affect that tends to evolve in direction of typical depression. On the basis of our previous study on psychopathology and dynamics of different types of depression [14] we suggest, and this suggestion is confirmed by the data from primary care, that depression has several stages of development. Those are: • Prodrome with non-specific symptoms of emotional and vegetative instability; • Anxious stage including three substages: Ⱦ situation anxiety with a concrete cause, Ⱦ free-floating anxiety with changing subjects of anxiety, mainly determined by chance, Ⱦ anxiety with no cause (without subject); • Depressive stage including three substages: Ⱦ depression with “anxious” elements within sadness condition, Ⱦ depression with hidden anxiety, but with domination of sadness, Ⱦ depression with areactivity / hyporeactivity and psychomotor retardation. Operational diagnosis registers only a concrete stage at the moment the patient is seeking help. Identifying dynamic aspects of diagnosis seem to be a task for future classifications. A dynamic hierarchy and multiple interrelationships between depression and anxiety should be taken into account in the development of future psychiatric diagnostic systems. It could be functional diagnostics, which consider, anxietydepressive affective disorder as cohesive entity, a kind of clinical continuum from adjustment disorders with protracted anxiety and depressive symptoms to severe melancholic depression. The symptoms of GAD share many features with depression and often represent the prodromal phase of depressive episode. More or less similar relationship can be revealed between panic disorder at the whole context and affective spectrum disorders. The differences are much more connected with physiological (including emotional and vegetative) reactivity than psychopathology itself. There are also some specific problems Russian and Russianspeaking psychiatrists face while using ICD-10. Regarding the affective spectrum disorders more few categories should be considered. Majority of Russian-speaking psychiatrists, especially those who have much experience in treatment of victims of large-scale 13 disasters, military combat or terrorist attacks are critical about a wider application of the clinical diagnosis “post-traumatic stress disorder” (PTSD) [15-18]. A significant part of conditions identified in English-language publications as PTSD are interpreted in Russia in a different way: primarily as long-term depression, or polymorphic conditions, or a combination of dysthymia, mild cognitive disorders, personality deviations and psychosomatic dysfunctions, sometimes with excessive alcohol consumption or drug abuse. The nature of such disorders is understood rather as multifactorial, and not exclusively psychotraumatic. For instance, in the persons involved in elimination of the consequences of the Chernobyl disaster in 1986, persistent disorders developed as a response to a combined (synergic) effect of a number of harmful factors while every single factor was not really pathogenic. Among them are extreme psychological and physical tension, disrupted biological rhythm in the first months after the disaster because of hard work in shifts associated with construction of protective “sarcophagus”, exposure to low doses of radiation (insufficient for development of radiation disease), dust, polluted air, especially in the environment of miners digging a tunnel under the destroyed nuclear reactor, other unfavorable factors connected with emergency work in Chernobyl. Many of the rescue workers experienced asthenic, psychovegetative, affective spectrum disturbances or stable disorders for the long time [19]. But official medicine didn’t find some specific reason and specific “name” for their morbid condition. It didn’t meet criteria of radiation disease and didn’t meet full criteria of PTSD. Their symptomatology in development with tendency of worsening intellectual and physical productivity was much more close to so called organic psychosyndrom by E. Bleuler [20]. Similar ideas about multiple nature and polymorphism of symptomatology of the post-traumatic stress disorders are rather rare but can be found in current English-language literature [21,22]. There is a semantic inaccuracy that should absolutely be deleted from the future ICD-11: it has to do with the categorization of stress related disorders (F 43). It has been formulated as “reaction to severe stress”. This seems illogical because «stress» in itself is a “reaction” of adaptation to changing environment. More appropriate could be use the common category stress disorders. According to opinion of the most of Russian speaking psychiatrists, the category “somatization disorder” (F45.0) has no real clinical ground and is contradictory in itself. The point is that somatization is not a state but the process of involvement of different somatic functions (vegetative, metabolic,neuroendocrine, immune, trophic) into pathological condition. According to tradition [23,24], somatization can be interpreted as reflection of primary affective disorders (anxiety and depression) on vegetative-somatic level. Historically the notion “somatization disorder” is only other name of “conversion disorder”, that consider psychodynamic interpretation of psychogenic or neurotic disturbances in old terminology. “Somatoform disorders” in the whole are very common, mostly as somatoform autonomic dysfunction (F 45.3) as usual with subaffective ground.
