Prevalence and comorbidity of affective disorders in persons making suicide attempts in Hungary: importance of the first depressive episodes and of bipolar II diagnoses

BACKGROUND: The purpose of this study was to investigate the prevalence and comorbidity of affective disorders, especially current major depressive episode and bipolar disorder among suicide attempters in Hungary. METHODS: Using a structured interview (Mini International Neuropsychiatric Interview) determining 16 Axis I psychiatric diagnoses defined by the DSM-IV and a semistructured interview collecting background information, the authors examined 100 consecutive suicide attempters, aged 18-65. RESULTS: Eighty-eight percent of the attempters had one or more current diagnoses on Axis I. In 69% it was major depressive episode and 60% of them were suffering their first episode. Thirty-five percent of the patients with current major depressive episode had had hypomanic (n=19) or manic (n=5) episodes in the past. Seventy percent of the individuals received two or more current diagnoses on Axis I. Eighty-six percent of all current Axis I disorders (except major depressive episode) were diagnosed together with a current major depressive episode. The diagnosis of current major depressive episode and the number of current psychiatric disorders was significantly and positively related to the number of suicide attempts, but the diagnosis of past major depressive episode was not. LIMITATIONS: This study included suicide attempters who had presented selfpoisoning, but not individuals with very high risk of fatality. CONCLUSIONS: In suicide attempters there is a very high prevalence of affective disorders, especially major depression, first episode of major depression and bipolar II disorder. This study underlines the importance of early detection and treatment of psychiatric disorders for the prevention of suicidal behavior.     

Job strain, burnout, and depressive symptoms: a prospective study among dentists

BACKGROUND: Burnout has been presented as an antecedent of depression, but longitudinal data are lacking. We investigated whether burnout mediates the association between job strain and depressive symptoms. METHODS: Two surveys were conducted. In 2003, 71% of Finnish dentists were reached, and the response rate of the 3-year follow-up was 84% (n=2555). Burnout was measured with the Maslach Burnout Inventory and depressive symptoms with the Beck Depression Inventory. The sequences 'job strain-burnout-depressive symptoms' and 'job strain-depressive symptoms-burnout' were investigated with logistic regression analyses. RESULTS: Of the burnout sufferers without depressive symptoms at baseline, 23% reported depressive symptoms at follow-up. The adjusted odds ratio of burnout for depressive symptoms was 2.6 (95% CI 2.0-3.5). The effect of job strain on depressive symptoms had an OR of 3.4 (95% CI 2.0-5.7), but it disappeared when adjusted for burnout. Of those who had depressive symptoms without burnout at baseline, 63% had burnout at follow-up. The adjusted odds ratio of depressive symptoms for burnout was 2.2 (95% CI 1.4-3.4). The effect of job strain on burnout had an OR of 27.9 (95% CI 6.5-120.2) for the men and 4.9 (95% CI 2.5-9.6) for the women. These effects remained significant after adjustment for depressive symptoms. LIMITATIONS: The study was conducted among one occupational group. CONCLUSIONS: There is a reciprocal relationship between burnout and depressive symptoms. Job strain predisposes to depression through burnout. In comparison, job strain predisposes to burnout directly and via depression.     

Bipolar mood disorders among Polish psychiatric outpatients treated for major depression

BACKGROUND: Significant proportion of patients treated for depression may have various types of bipolar mood disorders. The aim of the study was to assess the frequency of bipolar disorders among outpatients having at least one major depressive episode, treated by 96 psychiatrists, representing all regions of Poland. METHODS: The study included 880 patients (237 male, 643 female), identified to following diagnostic categories: bipolar I, bipolar II, bipolar spectrum disorder and major depressive disorder. RESULTS: Bipolar mood disorders were found in 61.2% of patients studied, bipolar I more frequent in men and bipolar II in women, and bipolar spectrum in 12% of patients. Patients with age ranges 19-49 and 50-65 years did not differ as to the percentage of diagnostic categories. Patients with bipolar mood disorders compared to major depressive disorder had significantly more frequent family history of bipolar disorder, premorbid hyper- or cyclothymic personality, early onset of depression, symptoms of hypersomnia and hyperphagia, psychotic depression, post-partum depression, and treatment-resistant depression. Bipolar spectrum patients had most clinical features similar to classic types of bipolar disorders. LIMITATIONS: Neither structured interview for family history, nor formal criteria for a number of clinical manifestations were used. The population treated by psychiatrists may not be representative and present a subgroup with more severe mood disorders. CONCLUSIONS: Bipolar mood disorders may be very prevalent among depressive outpatients treated by psychiatrists in Poland, which is confirmed by the results of recent studies. Bipolar patients (including bipolar spectrum) significantly differ from major depressive disorder as to numerous clinical features related mostly to depressive episode.     

Primary and secondary affective disorders: baseline characteristics of unipolar patients

We studied 569 patients with RDC non-bipolar major depressive disorder from the clinical portion of the NIMH Program on the Psychobiology of Depression. Primary (n = 327; never had a non-affective disorder), secondary (n = 191; had a non-affective disorder before ever having a major depressive episode), and "complicated' (n = 51; had at least one depressive episode before and another since developing a non-affective condition) patients were compared on demographic variables, past episodes of depression, past treatments received, and symptoms seen in the index episode. For most characteristics, the groups fell in the order primary, secondary, complicated, such that complicated cases had the earliest onset, the longest duration and the greatest severity in the index episode. These data do not discriminate between two hypotheses: that secondary and complicated depressions are basically depressions which happen to occur in a non-affectively ill person, or that they are different disorders which are distinguished clinically by characteristics related to severity.     

The prevalence of depression among Australian nursing home residents: results using draft ICD-10 and DSM-III-R criteria

The aims of this study were, first, to estimate the prevalence of depressive disorders in Australian nursing home residents using international diagnostic criteria, and second, to explore environmental determinants of such disorders. Residents of 24 nursing homes were surveyed using the Canberra Interview for the Elderly (CIE) and a range of environmental measures was also taken. Of 323 residents who were screened for cognitive impairment, 165 (51%) scored 18 or above on the Mini-Mental State Examination (Folstein et al. 1975), and were interviewed with the CIE. According to DSM-III-R criteria and the CIE, the prevalence of major depressive episode was 9.7%. Using ICD-10 criteria, 6.1% of residents suffered from a severe depressive episode, 6.7% from a moderate depressive episode and 6.7% from a mild depressive episode. Some measures of the social environment were significantly related to depressive symptoms.     

Suicidal behaviour among primary-care patients with depressive disorders

BACKGROUND: Most national suicide prevention strategies set improved detection and management of depression in primary health care into a central position. However, suicidal behaviour among primary-care patients with depressive disorders has been seldom investigated. METHOD: In the Vantaa Primary Care Depression Study, a total of 1119 primary-care patients in the City of Vantaa, Finland, aged 20 to 69 years, were screened for depression with the Primary Care Evaluation of Mental Disorders (PRIME-MD) questionnaire. Depressive disorders were diagnosed with the Structured Clinical Interview for DSM-IV Axis I Disorders (SCID-I), and the 137 patients with depressive disorder were included in the study. Suicidal behaviour was investigated cross-sectionally and retrospectively in three time-frames: current, current depressive episode, and lifetime. Current suicidal ideation was measured with the Scale for Suicidal Ideation (SSI), and previous ideation and suicide attempts were evaluated based on interviews plus medical and psychiatric records. RESULTS: Within their lifetimes, 37% (51/137) of the patients had seriously considered suicide and 17% (23/137) attempted it. Lifetime suicidal behaviour was independently and strongly predicted by psychiatric treatment history and co-morbid personality disorder, and suicidal behaviour within the current episode was predicted most effectively by severity of depression. CONCLUSIONS: Based on these findings and their convergence with studies of completed suicides, prevention of suicidal behaviour in primary care should probably focus more on high-risk subgroups of depressed patients, including those with moderate to severe major depressive disorder, personality disorder or a history of psychiatric care. Recognition of suicidal behaviour should be improved. The complex psychopathology of these patients in primary care needs to be considered in targeting preventive efforts.     

Major depression in patients with panic disorder: factors associated with course and recurrence

The relationship between anxiety and depressive disorders has been the subject of considerable interest and controversy. In this study, the occurrence and course of affective illness was systematically examined in 63 patients meeting DSM-III-R criteria for panic disorder. Forty (63%) of the patients had experienced at least one major depressive episode. Of these, 13 (32.5%) experienced their first depressive episode prior to the onset of panic disorder, 15 (37.5%) experienced their first depressive episode after the onset of panic disorder, and in 12 (30.0%) the onset of the disorders was concurrent. Patients with agoraphobia had comparable rates of depression (68%) to patients without agoraphobia (53%, P = NS), and they had similar temporal patterns of depressive illness. Comorbidity with social phobia was associated with an increased longitudinal likelihood of major depression compared to patients without this comorbid diagnosis (P less than 0.05). Patients with longer duration of illness, early onset depression, melancholic depression, or family histories of anxiety or depression had an increased likelihood of having experienced recurrent depression. These findings are discussed in the context of current theories regarding the development of affective illness in patients with anxiety disorders.     

Psychosocial impairment associated with bipolar II disorder

BACKGROUND: Significant research has looked at the psychosocial impairment associated with bipolar I disorder and major depressive disorder. Far less is known about the impact of bipolar II disorder. The present study assessed the social and work impairment associated with bipolar II disorder and whether these are more or less severe than those associated with bipolar I disorder or major depressive disorder. METHODS: Psychiatric outpatients with bipolar II disorder (n=89), bipolar I disorder (n=45) and major depressive disorder (n=1251) were assessed cross-sectionally by highly trained raters using semi-structured interviews. Participants were in a major depressive episode. Groups were compared on a series of indicators of psychosocial functioning. RESULTS: Bipolar I and II disorder were associated with greater absenteeism from work due to psychopathology compared to major depressive disorder. The bipolar disorders also had higher rates of hospitalization and suicide attempts. Bipolar II disorder had fewer hospitalization than bipolar I disorder which may have led to slightly less severe work impairment. Both conditions had similar rates of serious suicide attempts. LIMITATIONS: The study was cross-sectional and retrospective. Furthermore, the sample consisted of outpatients seeking treatment, limiting generalizability to other settings. CONCLUSION: Bipolar II disorder is associated with serious work impairment and a high number of serious suicide attempts. The level of impairment is more similar than it is different from that associated with bipolar I disorder. Clinicians would be mistaken to presume that the "softer" bipolar spectrum, specifically bipolar II disorder, is less impairing than bipolar I disorder.     

Chronic mood disorders in depressed outpatients: Diagnosis and response to pharmacotherapy

The current study was devised to assess the utility of Research Diagnostic Criteria (RDC) categories used to classify minor mood disorders. Similar categories are to be used in the APA's Diagnostic and Statistical Manual, 3rd edition. The patient sample consisted of 64 consecutive admissions to a double-blind trial of amitriptyline, perphenazine and the combination as treatment for depression. Patients who met RDC for a current episode of major depressive disorder were given 4 weeks of pharmacotherapy as treatment.Chronic mood disorders were also assessed using RDC criteria. This evaluation revealed that only 34% met criteria for an episode of major depressive disorder alone, while 36% met criteria for intermittent depressive disorder, 14% for cyclothymic personality and 16% for labile personality in addition to being in a current major depressive episode. These 4 diagnostic subgroups were compared on demographic characteristics, childhood history, psychiatric history, presenting patterns of symptoms and social functioning, and response to treatment. Differences were noted in the subgroups in presenting symptom levels and residual impairment. However, there was no differential response to a brief course of antidepressant pharmacotherapy in patients with and without chronic minor mood disorders. Most patients showed an improvement during the brief course of treatment. Thus, the presence of a chronic minor mood disorder does not appear to be a contraindication for use of medication in patients who also are currently experiencing a major depressive episode.     

Past and familial depression predict current symptoms of professional burnout

BACKGROUND: Despite a substantial association between professional burnout and depression, the exact nature of the relationship is unclear. It is hypothesized that an underlying susceptibility for depression is associated with an enhanced risk for professional burnout. In the present study, the relationship was examined between indices of personal and familial history of depression and current symptoms of burnout. METHODS: Respondents were 3385 employees of different work settings (61% female, age 18-65 years), who completed questionnaires regarding demographic variables, working hours, personal and familial history of depression, current depressive symptomatology, and current symptoms of professional burnout. RESULTS: After controlling for background variables, the strongest predictor of all three burnout facets was current depressive symptomatology. Independent of the effects of background variables and current depressive symptoms, having ever experienced a depressive episode further predicted current symptoms of two burnout facets: emotional exhaustion (OR=1.82, 95% CI=1.38-2.40, P<0.001) and cynicism (OR=1.51, 95% CI=1.16-1.98, P=0.002). In addition, a history of depression in close family members independently predicted current symptoms of emotional exhaustion (OR=1.63, 95% CI=1.27-2.10, P<0.001), while a trend appeared for a similar effect on cynicism (OR=1.23, 95% CI=0.96-1.58, P=0.095). LIMITATIONS: The study is based on a cross-sectional retrospective design. CONCLUSIONS: A predisposition for depression, as reflected by a personal and familial history of depression, may enhance the risk for burnout.     

The relationship between quality of interpersonal relationships and major depressive disorder: findings from the National Comorbidity Survey

BACKGROUND: The current study compared the quality of interpersonal relationships in individuals with major depressive disorder to individuals with dysthymia, comorbid depression, nonaffective disorders, and no psychiatric disorders. METHODS: Using data from the National Comorbidity Study, a series of logistic regressions, controlling for demographic variables, were conducted to examine the strength of the association between a major depressive disorder and interpersonal dysfunction (positive and negative interactions) in contrast to other psychiatric disorders. RESULTS: Respondents with current major depressive disorder reported significantly fewer positive interactions and more negative interactions with their spouse or live-in partner than those with nonaffective disorders, and than those with no psychiatric disorders. There were no significant differences in quality of interpersonal relationships between respondents with major depressive disorder and those with dysthymia. Among those with major depressive disorder, comorbidity or treatment-seeking behavior did not significantly contribute to degree of interpersonal difficulties. The strength of the association between interpersonal dysfunction and depression were, in general, comparable for men and women with major depressive disorder. LIMITATIONS: The cross-sectional design of this report precludes inferences regarding causality between quality of interpersonal relationship and current major depressive disorder. CONCLUSIONS: The results of this study indicate that, relative to psychiatric illness in general, poor intimate relationships are characteristic of a current major depressive disorder.     

Clinical characterization of depressive mixed state in bipolar-I patients: Pisa-San Diego collaboration

BACKGROUND: Although mixed states were classically described as various concomitant admixtures of depression and mania, the official current definitions in both DSM-IV and ICD-10 tend to restrict the concept to manic patients with full syndromal depression. Recent research has actually shown that mania with few depressive symptoms constitutes the most prevalent clinical presentation of mixed or dysphoric mania. Major depressive patients with few concomitant manic symptoms are not officially recognized within the current nosology. In this paper we attempt to delineate the clinical profile of such depressive mixed states in the context of bipolar I disorder. METHODS: In the Pisa day center, we studied 195 bipolar I patients who either met Pisa criteria for bipolar mixed state (n=159) or DSM-III-R criteria for major depressive episode (bipolar major depression or B-MD, n=36). Of the 159 patients identified by Pisa criteria as mixed state, 86 also met the criteria of the DSM-III-R for mixed episode (core mixed state or MS group), while 32 met the DSM III-R criteria for major depressive episode (provisionally defined as depressive mixed states, D-MS); the remaining patients (n=41, 25.7%) with predominatly manic picture were not included in the present comparisons. RESULTS: The three groups (B-MD, MS and D-MS) had close similarities in clinical and sociodemographic characteristics such as age, sex distribution, marital status, schooling, residence, age at onset, age of first treatment, age of first hospitalization, degree of chronicity of the index episode, stressor within the 6 months before the index episode, lifetime suicide attempts and premorbid temperament. First degree family history for bipolar illness and that for other mental disorders was also similar, except for major depression that was more common among the relatives of D-MS. MS and D-MS were further distinguished from B-MD by the fact that the latter followed a more 'cyclic' course with shorter yet greater number of episodes, and which began with a pure depressive episode; by contrast, MS and D-MS had fewer episodes of longer duration, less interepisodic remission, and tended to begin with a mixed episode. Incongruous psychotic features were more common in the two mixed groups compared to B-MD, and the most common features of the D-MS group were agitation, psychotic depression with irritable mood, pressured speech and/or flight of ideas. LIMITATION: It was not feasible to collect information blind to clinical status in patients with severe psychotic mood states. CONCLUSION: These data confirm the existence of psychotic agitated depressive mixed states with flight of ideas, distinct from cyclic retarded pure bipolar depressive states. The recognition of these affective states is clinically important to protect patients from the potentially harmful indiscriminate use of antidepressants and to provide them with the benefits of an anticonvulsant, a short-term neuroleptic, or ECT.     

Two-year prospective study of major depressive disorder in HIV-infected men

OBJECTIVE: The risks and factors contributing to major depressive episodes in HIV infection remain unclear. This 2-year prospective study compared cumulative rates and predictors of a major depressive episode in HIV-infected (HIV+) men (N=297) and uninfected (HIV-) risk-group controls (N=90). METHODS: By design participants at entry were without current major depression, substance dependence or major anxiety disorder. Standardized neuromedical, neuropsychological, neuroimaging, life events, and psychiatric assessments (Structured Clinical Interview for DSM III-R) were conducted semi-annually for those with AIDS, and annually for all others. RESULTS: Lifetime prevalence of major depression or other psychiatric disorder did not differ at baseline between HIV+ men and controls. On a two-year follow-up those with symptomatic HIV disease were significantly more likely to experience a major depressive episode than were asymptomatic HIV+ individuals and HIV-controls (p<0.05). Episodes were as likely to be first onset as recurrent depression. After baseline disease stage and medical variables associated with HIV infection were controlled, a lifetime history of major depression, or of lifetime psychiatric comorbidity (two or more psychiatric disorders), predicted subsequent major depressive episode (p<0.05). Neither HIV disease progression during follow-up, nor the baseline presence of neurocognitive impairment, clinical brain imaging abnormality, or marked life adversity predicted a later major depressive episode. LIMITATIONS: Research cohort of men examined before era of widespread use of advanced anti-HIV therapies. CONCLUSIONS: Symptomatic HIV disease, but not HIV infection itself, increases intermediate-term risk of major depression. Prior psychiatric history most strongly predicted future vulnerability.     

Is there circannual variation of human platelet 5-HT(2A) binding in depression?

BACKGROUND: Seasonal variations in onset of mood disorders and in serotonergic function are reported, but their relationship is unclear. METHODS: Circannual variation in platelet 5-HT(2A) binding was measured in 68 healthy subjects and 121 patients with a major depressive episode. In 73 patients the current episode began during Spring or Fall. RESULTS: Significant, but different, circannual variations were found in patients compared with controls. Controls had two peaks of B(max), one in Spring and another in Fall. Fall and Winter K(D) was 41% lower compared with Spring and Summer K(D). Patients had a peak of B(max) in early Spring and a lesser one in late Fall. B(max) during Spring and Fall was 12% higher compared with Winter and Summer. K(D) was higher during October through February compared with the rest of the year. B(max) in patients was higher compared with controls in March. The opposite difference was observed in September-December. These differences from controls were mostly due to patients with an onset of the current major depressive episode during Spring or Fall. CONCLUSIONS: Patients with a major depressive episode differed from controls in circannual variation of platelet 5-HT(2A) binding. This may reflect a vulnerability to seasonal effects in patients with mood disorders.     

Personality traits and personality disorders in early onset versus late onset major depression

BACKGROUND: We aimed to determine the relationship between certain personality disorders and/or personality traits and early onset major depression. METHODS: A total of 400 depressed primary care patients were assessed for personality disorders using the SCID screen and for personality traits using the Karolinska Scales of Personality (KSP) questionnaire. Early onset was defined as onset of the first episode before the age of 26. Logistic regressions were performed to reveal relationships after adjustment for sex, age and number of previous episodes. RESULTS: Both groups had a similar severity of current illness determined by the Montgomery-Asberg Depression Rating Scale. Those with an early onset presented with a more debilitating course, seen in the form of more depressive episodes and previous hospitalisations in spite of their younger age. Early onset was also an independent predictor for avoidant, borderline and paranoid personality disorders. It also predicted increased scores on the KSP scales Psychic anxiety, Psychasthenia, Muscular tension, Suspicion and Irritability, and decreased Socialisation. LIMITATIONS: The evaluation was performed as a self-assessment, subjects had a superimposed major depressive episode when assessed, and subgroups of individuals were not eligible. CONCLUSIONS: Early onset major depression is a predictor for personality pathology and deviant personality traits. A better understanding of the interplay between genetics and environment that underlies this phenomenon will help to improve the long-term course in afflicted individuals.     

Burnout as a predictor of medically certified sick-leave absences and their diagnosed causes

Stress-related illnesses, such as mental, behavioral, and cardiovascular diseases, are common causes for sick-leave absences. It is generally assumed that burnout, the chronic stress syndrome, also leads to absenteeism and poor health, but this assumption has rarely been tested. The authors investigated the prospective effect of burnout on registered sick leaves and their causes in industrial employees. We collected the number of medically certified (> 3 days) absence episodes and their causes (according to the International Statistical Classification of Diseases-10 diagnostic categories) of 3,895 industrial employees from a company register during 1995 to 1998. Burnout was measured in 1996 with the Maslach Burnout Inventory-General Survey, which defines burnout as a 3-dimensional syndrome consisting of components of exhaustion, cynicism, and lack of professional efficacy. In Poisson regression models, the total burnout score increased the risk for future all-cause absences after adjustment for age, sex, occupation, and baseline absence. Burnout increased the risk of future absences because of mental and behavioral disorders, diseases of the circulatory system, diseases of the respiratory system, and diseases of the musculoskeletal system. Of the separate components of burnout, exhaustion was strongly related to future diseases of the circulatory system, whereas cynicism was strongly related to future diseases of the digestive system. Other differentiated effects were also found. The results of this study show that burnout is related to increased risk of future illness. This implies that burnout prevention can reduce future absenteeism and has a major economic impact on work life and health care.     

Major depressive episode among young adults: CIDI-SF versus SCAN consensus diagnoses

BACKGROUND: We aimed to evaluate the diagnostic accuracy of a highly structured diagnostic interview in relation to a semi-structured diagnostic procedure. We compared the World Health Organization Composite International Diagnostic Interview Short Form (CIDI-SF) in diagnosing major depressive episode (MDE) to consensus diagnoses based on the SCAN interview (Schedules for Clinical Assessment in Neuropsychiatry). METHOD: Subjects comprised a follow-up sample of 239 20-24-year-old former high-school students who were administered the SCAN and immediately thereafter the CIDI-SF. Concordance was estimated for 12-month MDE, using different cut-points of the CIDI-SF and for any affective disorders. RESULTS: Correspondence between instruments was moderate for MDE (kappa = 0.43, sensitivity 0.71, specificity 0.82), but better for any affective disorder (kappa = 0.60, sensitivity 0.70, specificity 0.90). Most false negatives suffered from their depression as much as those correctly identified by the CIDI-SF. False negativity was mainly due to not endorsing the stem questions of the CIDI-SF. Of the false positives almost half had an affective disorder other than MDE. CONCLUSIONS: The CIDI-SF seems to function best in identifying a broader category of affective disorders. It could be useful in large-scale community surveys where more extensive psychiatric interviews are not feasible.     

Body dysmorphic disorder in outpatients with major depression

BACKGROUND: Body dysmorphic disorder (BDD) is a distressing and impairing preoccupation with an imagined or slight defect in appearance, with depression as its most frequent comorbid condition. The purpose of this study was to evaluate the rate of BDD in a cohort of consecutive outpatients with typical and atypical major depressive disorder. METHODS: Three hundred and fifty consecutive outpatient subjects with major depression who entered an antidepressant treatment study were evaluated drug-free with the SCID-P, SCID-II, a diagnostic module for BDD, and other measures. Depressed subjects with comorbid BDD were compared to those without BDD with regard to demographics, course of depression, comorbid conditions, and other relevant variables. RESULTS: Twenty-eight (8.0%) subjects had a lifetime history of BDD and 23 (6.6%) had current BDD. Those with comorbid lifetime BDD had an earlier age of onset of depression and longer duration of the current episode, but not a greater number of depressive episodes or greater severity of depression. Subjects with and without BDD were similar with respect to age, gender, and marital status. There was a higher rate of lifetime and current BDD in subjects with atypical depression than in those with non-atypical depression (14.4% compared to 5.1%; chi2 = 6.63; P = 0.01: 11.6% vs. 4.1%; chi2 = 7.02; P = 0.02). Subjects with BDD also had higher rates of social phobia, any eating disorder, and any somatoform disorder but not obsessive compulsive disorder. They also had higher rates of avoidant, histrionic, and dependent personality disorders. LIMITATIONS: As we did not specifically examine bipolar spectrum conditions, the present study cannot address to what extent BDD is comorbid with Bipolar-II disorder. CONCLUSIONS: BDD is frequently comorbid with major depression, is associated with an earlier age of onset of depression and longer duration of depressive episodes, and is found more frequently with atypical than non-atypical depression.     

Contributing factors to changes of cerebral blood flow in major depressive disorder

BACKGROUND: Results of single photon emission computed tomography (SPECT) regarding mood disorders have been inconsistent. The aim of the study was to elucidate factors contributing to changes in cerebral blood flow in patients with major depressive disorder. METHODS: A total of 89 consecutive patients diagnosed with major depressive disorder using DSM-IV semistructured interviews were evaluated using single photon emission computed tomography, the 17-item Hamilton Rating Scale for Depression (HRSD), and the Global Assessment of Function (GAF) scale. Nineteen of these patients also underwent the same tests during remission. RESULTS: Global cerebral blood flow (gCBF) was significantly higher during remission than at the time of enrollment. Significant correlations were seen between gCBF and age, duration of previous episode of depression, and hypochondriasis. However, no correlation was seen between gCBF and HRSD, GAF, severity and duration of depressive episode, or melancholia-type depression. Correlations between gCBF and age were seen only at enrollment and disappeared during remission. No differences in regional cerebral blood flow at any site were seen between time of enrollment and remission for the same patient. LIMITATION: Analysis that adequately accounts for these factors to changes of cerebral blood flow in major depressive disorder will require a large subject population. CONCLUSIONS: These results suggest that although there is a decrease in gCBF in major depressive disorder, the level of the decrease is determined by conditions present before episode onset, rather than by the characteristics of the episode itself. The findings also suggest that the correlation between gCBF and age is state-dependent.     

Neurotic disorders and the receipt of psychiatric treatment

BACKGROUND: Access to psychiatric treatment by people with neurotic disorders in the general population is likely to be affected both by the severity of disorder and by sociodemographic differences. METHOD: In the household component of the National Surveys of Psychiatric Morbidity > 10,000 subjects in Great Britain with psychiatric symptoms were interviewed using the CIS-R. They were also asked about difficulties experienced in performing seven types of everyday activity. All subjects classed as having an ICD-10 disorder were questioned about their experience of treatment with antidepressants, hypnotics, and counselling or psychotherapy. RESULTS: Less than 14% of people with current neurotic disorders were receiving treatment for them. Within the previous year, only a third had made contact with their primary care physician for their mental problem: of these < 30% were receiving treatment. Overall, 9% of people with disorders were given medication and 8% counselling or psychotherapy. A diagnosis of depressive episode was that most associated with antidepressant medication. Treatment access was affected by employment status, marital status, and age, but the major determinant was symptom severity. Neither sex nor social class influenced which people received treatment. CONCLUSIONS: People with psychiatric disorders seldom receive treatment, even when they have consulted their primary care physician about them. In many cases, this must represent unmet needs with a strong claim on health resources. There are also inequalities in the receipt of treatment, although the major influence is the severity of disorder.
