Trait and state aspects of harm avoidance and its implication for treatment in major depressive disorder, dysthymic disorder, and depressive personality disorder.

The authors evaluated the trait/state issues of harm avoidance in depressive-spectrum disorders and its predictive potential for antidepressant response. Subjects with Diagnostic and Statistical Manual of Mental Disorders (4th edn; DSM-IV) major depressive disorder (n = 39), dysthymic disorder (n = 37), depressive personality disorder (n = 39), and healthy control subjects (n = 40) were evaluated with the Temperament and Character Inventory and the 17-item Hamilton Depression Rating Scale (HDRS-17) at baseline and after a 12 week antidepressant treatment period. Higher harm avoidance scores predicted lesser improvement in subjects with dysthymic disorder and major depressive disorder, as determined by lesser decrease in HDRS-17 scores. Mean harm avoidance scores in depressed subjects were consistently greater than those in healthy controls, controlling for age, gender and diagnosis. Mean harm avoidance scores decreased significantly in all depressive-spectrum disorders after treatment, but still remained higher than harm avoidance scores in control subjects. The present study reports that harm avoidance is a reliable predictor of antidepressant treatment in subjects with major depressive disorder and dysthymic disorder and that harm avoidance is both trait- and state-dependent in depressive-spectrum disorders.

The relationship between anxiety and depression: a clinical comparison of generalized anxiety disorder, dysthymic disorder, panic disorder, and major depressive disorder.

This study examined the relationship between the chronic disorders, generalized anxiety disorder (GAD) and dysthymic disorder (DD), and the more acute disorders, panic disorder (PD) and major depressive disorder (MDD) in 110 psychiatric outpatients with diagnoses of either PD, MDD, GAD, or DD. Pure, mixed, and early-/late-onset forms of the chronic disorders were compared with each other and then with PD and MDD on clinical measures and psychiatric history. Minimal differences were found between pure GAD and mixed GAD or between pure DD and mixed DD. The chronic disorders, DD and GAD, had distinct clinical symptom profiles when compared with each other and appeared more closely related to their parent disorders than to each other. However, despite these similarities, there were significant differences between DD and MDD in contrast to the minimal differences between GAD and PD, providing less support for GAD as a valid diagnostic category separate from PD. Comparisons of early-/late-onset DD and GAD showed more severe symptoms in late-onset DD, in contrast to more severe symptoms in early-onset GAD. These varying patterns of symptom severity may warrant study for further syndromal delineation.

Longitudinal comparison of depressive personality disorder and dysthymic disorder.

BACKGROUND: Few studies have compared the related diagnostic constructs of depressive personality disorder (DPD) and dysthymic disorder (DD). The authors attempted to replicate findings of Klein and Shih in longitudinally followed patients with personality disorder or major depressive disorder (MDD) in the Collaborative Longitudinal Personality Disorders Study. METHODS: Subjects (N = 665) were evaluated at baseline and over 2 years (n = 546) by reliably trained clinical interviewers using semistructured interviews and self-report personality questionnaires. RESULTS: Only 44 subjects (24.6% of 179 DPD and 49.4% of 89 early-onset dysthymic subjects) met criteria for both disorders at baseline. Depressive personality disorder was associated with increased comorbidity of some axis I anxiety disorders and other axis II diagnoses, particularly avoidant (71.5%) and borderline (55.9%) personality disorders. Depressive personality disorder was associated with low positive and high negative affectivity on dimensional measures of temperament. Depressive personality disorder subjects had lower likelihood of remission of baseline MDD at 2-year follow-up, whereas DD subjects did not. The DPD diagnosis appeared unstable over 2 years of follow-up, as only 31% (n = 47) of 154 subjects who had DPD at baseline and also had follow-up assessment met criteria on blind retesting. LIMITATIONS: Results from this sample may not generalize to other populations. CONCLUSIONS: Depressive personality disorder and dysthymic disorder appear to be related but differ in diagnostic constructs. Its moderating effect on MDD and predicted relationship to measures of temperament support the validity of DPD, but its diagnostic instability raises questions about its course, utility, and measurement.

Cognitive-behavioral analysis system of psychotherapy: an interactional treatment approach for dysthymic disorder.

Dysthymic disorder, a troublesome problem for many young adults, can be effectively treated by focusing the client's attention on the interactional problems the person reports to the therapist. In therapy, interactional issues frequently take a backseat to the more obvious intrapersonal symptoms that many contemporary theories of depression emphasize. James Coyne (1976, 1982) has recently pointed out this oversight to workers in the field. The first part of the paper will discuss several aspects of current treatment approaches that deal with depression from an intrapersonal perspective. I will argue that a more realistic approach to treatment must involve accentuating the interactional predicament of the dysthymic. The Cognitive-Behavioral Analysis System, which will be introduced in the second part of the paper, approaches both the intrapersonal and interpersonal problems of the dysthymic from an interactional perspective. Four successful direct replication cases will be described, illustrating the efficacy of such an approach.

Recognition and management of dysthymic disorder.

Dysthymic disorder, a chronic disturbance of mood, manifests as depressed mood for most of the day, more days than not, for at least two years. In children, dysthymia may present as irritable mood, and a duration of symptoms of only one year is required to make the diagnosis. By definition, there is no history of a major depressive disorder. Associated symptoms include poor appetite or overeating, insomnia or hypersomnia, poor concentration or difficulty making decisions, low energy, low self-esteem and feelings of hopelessness. Because of the chronic nature of this disorder, treatment requires an understanding approach and continuity of care.

Attention deficit hyperactivity disorder, combined type, dysthymic disorder and anxiety disorders: differential patterns of neurodevelopmental deficits.

The associations between neurodevelopmental deficits (NDD) and (1) attention deficit hyperactivity disorder, combined type (ADHD-CT) and (2) internalising disorders have been replicated. To date, the specific association between standardized NDD and carefully defined ADHD-CT alone, dysthymic disorder alone and anxiety disorders alone has not been systematically investigated in children of primary school age. A cross-sectional study of NDD in 99 six- to 12-year-old children with categorically and dimensionally defined ADHD-CT alone, dysthymic disorder alone and anxiety disorders alone and 20 age-matched healthy children was undertaken. The ADHD-CT and dysthymic disorder groups had increased total neurological subtle signs, compared to the anxiety disorders group, which, in turn, had increased total neurological subtle signs compared with the healthy children. Interestingly, the dysthymic disorder children had increased conjugate eye gaze difficulties compared with the other three groups. The differences remained after controlling for full scale IQ. These findings suggest a neurobiological underpinning of dysthymic disorder, while confirming that of ADHD-CT in primary school age children. Future studies will explore whether the above more specific neurological subtle signs are developmental phase specific or independent associations.

Which anxiety disorders may differentiate attention deficit hyperactivity disorder, combined type with dysthymic disorder from attention deficit hyperactivity disorder, combined type alone?

OBJECTIVE: Attention deficit hyperactivity disorder, combined type (ADHD-CT), dysthymic disorder, and anxiety disorders frequently co-occur in primary school age children, although there have been no published data describing their association. We investigated the association of anxiety, defined from a parent or child perspective, with primary school-age children with ADHD-CT with and without dysthymic disorder. METHOD: One hundred and forty-six medication naïve children with ADHD-CT were studied. Two groups with and without dysthymic disorder were formed to compare parent and child reports of anxiety, using categorical and continuous measures of anxiety, using logistic regression. RESULTS: Separation anxiety disorder and social phobia were associated with primary school-age children with ADHD-CT and dysthymic disorder, compared to children with ADHD-CT without dysthymic disorder. CONCLUSIONS: The recognition of dysthymic disorder and anxiety disorders and their management in primary school-age children with ADHD-CT is generally poorly understood. The identification and elucidation of composite anxiety and depressive phenomena that may be systematically investigated through longitudinal studies of epidemiologically derived samples is needed in this particular group of children.

Venlafaxine in dysthymic disorder.

BACKGROUND: Dysthymic disorder is a chronic depression that is usually characterized by depression rating scale scores that are lower than those for major depressive disorder. Recent studies suggest that pharmacotherapy is quite effective in the treatment of patients with this condition and, in particular, that the newer antidepressants may be better tolerated than older tricyclic antidepressants. The purpose of this study was to investigate the use of a structurally novel antidepressant, venlafaxine, in the treatment of dysthymic disorder. METHOD: Seventeen patients with dysthymic disorder were entered into the study, and 14 completed it. A psychiatric interview was used to establish diagnosis, and behavior was assessed by using the Hamilton Rating Scale for Depression (HAM-D) and the Beck Depression Inventory (BDI). Patients were seen over a 9-week period, and venlafaxine treatment proceeded on an open-label basis, from a starting dose of 18.75 mg b.i.d. to a maximum dose of 225 mg/day. RESULTS: Two patients discontinued early because of side effects, and 1 patient took a single dose, felt better, and did not complete the trial. Analyses of all 17 patients showed significant improvement in HAM-D and BDI scores at the end of the study. Among the completers, there were two response patterns: one group of 7 patients responded quickly to low-dose (75 mg) venlafaxine, and a second group of 7 required the maximum dose. Three of the 7 high-dose patients showed considerable improvement. Side effects in this study were generally in keeping with what has been reported using venlafaxine in treatment of major depressive disorder. No patients evidenced increased blood pressure. CONCLUSION: Our study supports the treatment of dysthymic patients with venlafaxine, which has equal efficacy and greater tolerability than tricyclic antidepressants.

The relation between depressive symptoms and borderline personality disorder features over time in dysthymic disorder.

Dysthymic Disorder (DD) and Borderline Personality Disorder (BPD) frequently co-occur. To understand this association better, we tested four competing models of the relationship between depressive and BPD symptoms over time in DD: (a) no association between depression and BPD over time; (b) contemporaneous direct effects in which BPD features and depressive symptoms influence one another over a relatively short time period; (c) lagged direct effects in which one condition influences the other condition over a longer period; and (d) a fixed common factor underlies both depression and BPD, along with influences that are unique to each condition. We assessed 84 outpatients with DD three times over 5 years using semistructured interviews. Data were analyzed using structural equation modeling techniques. The fixed common factor model was the best fitting of the models, providing an excellent fit to the data. These results suggest that depressive symptoms and BPD features in DD arise from partially overlapping processes.

Late onset dysthymic disorder and major depression differ from early onset dysthymic disorder and major depression in elderly outpatients.

BACKGROUND: Age of onset may affect clinical features and prognosis in elderly patients with major depression (MDD), but there is a lack of such data in elderly patients with dysthymic disorder (DD) and systematic comparisons of late onset MDD and DD have not been conducted. METHODS: In a Late Life Depression Clinic, patients > or = 60 years old who met DSM-III-R or DSM-IV criteria for MDD or DD were studied. The 24-item Hamilton Rating Scale for Depression (HRSD) and SCID-P were completed, family history was obtained, and medical illnesses were assessed. RESULTS: In the total sample (n=370; 211 MDD and 159 DD), compared to early onset patients, late onset (onset > or =60 years) patients had a higher rate of cardiovascular disease (chi(2)=4.12, df=1, P<0.05), lower rate of anxiety disorder (chi(2)=4.19, df=1, P<0.05), and a lower rate of family history of affective disorder (chi(2)=9.37, df=1, P<0.002). Late onset DD patients were more likely to have cardiovascular disease than early onset DD patients (chi(2)=5.63, df=1, P<0.02), but the rate of cardiovascular disease did not differ between late and early onset MDD patients (chi(2)=0.35, df=1, P<0.6). Late onset MDD patients were less likely to have a family history of affective disorder than early onset MDD patients (chi(2)=10.71, df=1, P<0.001). Prevalence of anxiety disorders did not differ between the early and late onset MDD patients (chi(2)=0.07, df=1, P<0.79), but was more common in the early onset DD compared to the late onset DD patients (17.98% versus 4.29%, chi(2)=6.98, df=1, P<0.01). Late onset DD did not differ from late onset MDD in the rates of cardiovascular disease, anxiety disorders, and family history of affective disorder. Excluding patients with double depression (n=32) did not alter the cardiovascular or family history findings, but the difference in anxiety disorders between early and late onset DD patients was no longer significant. LIMITATIONS: Academic clinic sample results may not generalize to community populations. CONCLUSIONS: In the elderly, late-onset DD is typically different from early onset DD. Cerebrovascular disease appears to play a role in the etiology of late onset DD. The similarities between late onset DD and late onset MDD suggest a single condition along a continuum.

The impact of comorbid anxiety disorders on the course of dysthymic disorder: a 5-year prospective longitudinal study.

BACKGROUND: Few studies have examined the impact of comorbid anxiety disorder on the course of dysthymic disorder despite the high rate of comorbidity between these disorders. This research prospectively examines the naturalistic course of dysthymic disorder in patients with and without a comorbid anxiety disorder over a 5-year period. METHODS: Thirty-two comorbid patients and 54 non-comorbid patients with dysthymic disorder were assessed at three different time points (baseline, 30 months, and 60 months). Follow-up assessments included the Longitudinal Interval Follow-Up Evaluation and Hamilton Rating Scale for Depression (HRSD). RESULTS: The rate of recovery from dysthymic disorder was significantly lower in patients with (31.3%) than without (61.1%) comorbid anxiety disorders and, at all three time points, patients with comorbid anxiety had significantly higher HRSD scores. The estimated recovery rate from anxiety disorders was 53.8%. Only five of the comorbid patients recovered from both dysthymic disorder and all anxiety disorders during follow-up. Including new onsets, 72.1% of patients experienced an episode of an anxiety disorder during the 5 years. LIMITATIONS: There was no pure anxiety disorder group and patients were asked to report on relatively lengthy follow-up intervals. CONCLUSIONS: While the course of dysthymic disorder is debilitating, these results suggest that the prognosis for patients with a comorbid anxiety disorder is even poorer.

Characteristics of internalizing and externalizing disorders in medication-naive, clinically referred children with attention deficit hyperactivity disorder, combined type and dysthymic disorder.

OBJECTIVE: Internalizing and externalizing disorders are frequently comorbid with attention deficit hyperactivity disorder, combined type (ADHD-CT) and dysthymic disorder (DD) in referred primary school-age children, yet there has been relatively little systematic research of the nature of these comorbid disorders. We describe the characteristics of parent- and child-reported internalizing and externalizing disorders in primary school-age children with ADHD-CT and DD. METHOD: A cross-sectional study of 45 clinically referred medication naive children with ADHD-CT and DD, examining parent and child reports of internalizing and externalizing disorders, defined categorically and dimensionally. RESULTS: Generalized anxiety disorder and separation anxiety disorder were increased in the DD groups, whether ADHD-CT was present or not. Major depressive disorder was increased in the ADHD-CT and DD group compared to the ADHD-CT alone and the DD alone groups. Conduct disorder was increased in the ADHD-CT alone group compared to the DD with and without ADHD-CT groups. Verbal and fullscale IQ were increased in the DD groups, whether ADHD-CT was present or not, compared to the ADHD-CT alone group. CONCLUSIONS: There is emerging evidence that DD and anxiety may represent a different phenotypic expression of a common underlying aetiological process, while the co-occurrence of ADHD-CT and anxiety disorders remains unclear. Only the ADHD-CT and DD group is significantly associated with major depressive disorder, which suggests an additive effect. In contrast, conduct disorder and decreased verbal and fullscale IQ are only associated with the ADHD-CT group, which may suggest a protective effect of DD when comorbid with ADHD-CT. From a research perspective, it is important to confirm these found associations in larger samples derived from epidemiological populations.

[Dysthymic disorder and its treatment].

Dysthymia is a new nosographic category in the latest American and international classification of mental disorders. Dysthymics were previously considered either as "neurotic depressive characters" or "characterologic depressives." Today it has been demonstrated that the personality and affective traits of these patients are in fact simply different expressions of a constitutive predisposition to clinical depression. Some studies have shown biological and neurophysiological relationships between dysthymia and major mood disorders. We therefore submit that dysthymia constitutes a subaffective expression of the major depression phenotype. Other studies have demonstrated the short-term efficacy (6 weeks to 3 months) of antidepressants in this disorder. In this article, we present a prospective 2-years study comparing the efficacy of fluoxetine with tricyclic antidepressants. The results show not only the efficacy of fluoxetine in dysthymia, but especially, if we consider the degree of social adaptation, a much better response qualitatively. These patients, who were previously sentenced to a life of suffering, may now benefit from new mood-regulating agents. The benefit afforded by drug treatment must be supported by various supportive psychotherapies, which are also discussed.

Prevalence of dysthymic disorder in primary care.

BACKGROUND: Dysthymic disorder is characterised as a chronic state of depressed mood which is not otherwise attributable to physical, psychological or social events. While it can occur alone, there is increasing evidence that the majority of individuals who meet criteria for dysthymic disorder also experience more severe episodic mood disorders throughout their lifetime, and there is also an aggregation of mood disorders within their family members. Patients with dysthymic disorder are most often seen in primary care. Some researchers suggest that the majority of these individuals are never diagnosed or are not diagnosed until a more severe episodic mood disorder develops. The objective of this study was to determine the 12-month prevalence of Axis I psychiatric disorders, and in particular dysthymic disorder, in a primary care Health Service Organization in Ontario, Canada. METHODS: Eligible and consenting adults registered with a primary care Health Service Organization were screened using the modified form of the University of Michigan Composite International Diagnostic Interview. RESULTS: Of the 6280 eligible subjects, 4327 (69%) consented to screening. Two hundred and twenty-two (5.1%) subjects screened positive for dysthymic disorder. In addition, 90% of those who screened positive for dysthymic disorder also screened positive for other Axis I disorders including major depressive disorder, panic, simple phobia, and generalized anxiety disorder. CONCLUSIONS: There is much potential for the primary care physician to play a pivotal role in the recognition and treatment of dysthymic disorder and associated Axis I disorders. A focus on the family as a unit for care may be especially important given the reported aggregation of dysthymic disorder within families.

Affective disorders in children and adolescents: the dysthymic disorder dilemma.

From 60 patients referred for assessment of their depressive symptomatology, 13 were found to suffer from major affective disorder and 14 from dysthymic disorder. The results from self-rating scales (the Children's Depression Inventory and the Children's Depression Scale) were compared with the findings from diagnostic interviews (using DSM-III criteria). The large proportion of dysthymic disorders in this sample is compared to the low reported figure in most other samples and some comments about the possible usefulness of this diagnosis are made.

Personality disorders in elderly patients with dysthymic disorder.

The authors evaluated personality disorders in elderly patients with DSM-IV dysthymic disorder (DD) to identify prevalent personality disorders and their clinical correlates. Outpatients (>/=60 years; N=76) with DD were evaluated; most were male (65.8%) and had late age at onset (>50 years: 60.5%). Axis II disorders were present in 31.2% of patients, with obsessive-compulsive personality disorder (OCD; 17.1%) and avoidant personality disorder (11.8%) being the most common. Personality disorders were associated with an earlier age at onset of depressive illness, greater lifetime history of comorbid Axis I disorders, greater severity of depressive symptoms, and lower socioeconomic status. Personality disorders occurred in a minority of elderly patients with DD and mainly comprised the obsessive-compulsive and avoidant subtypes, similar to reports of personality disorders in elderly patients with major depression. In contrast, young adults with DD have been shown consistently to have personality disorders at high frequency. Together with the predominance of late onset and the lack of psychiatric comorbidity, the current findings on personality disorders reinforce our view that DD in elderly patients is typically a different disorder from DD in young adults.

Dysthymic disorder: treatment with mirtazapine.

Dysthymic disorder is a form of chronic depression which often has its onset in childhood or adolescence and is generally persistent throughout life. Although originally hypothesized to be preferentially treated with psychotherapy, recent pharmacological studies support the use of antidepressants to treat patients with dysthymic disorder. Mirtazapine is an antidepressant which has been recently released on the U.S. market. We studied the effects of 15 to 45 mg of mirtazapine in 15 patients with dysthymic disorder on an open label basis over a 10-week period. Four patients discontinued treatment because of sedation. Mirtazapine was effective and well tolerated in the remaining patients.

Chromium potentiation of antidepressant pharmacotherapy for dysthymic disorder in 5 patients.

BACKGROUND: Dysthymic disorder is a relatively common illness that is often treated with antidepressants. Compared with the study of major depression, there has been little systematic study of potentiation strategies for antidepressant-refractory dysthymic disorder. METHOD: Following a patient's report of dramatic response to the addition of chromium supplementation to sertraline pharmacotherapy for dysthymic disorder (DSM-IV), the authors initiated a series of single-blind and open-label trials of chromium picolinate or chromium polynicotinate in the treatment of antidepressant-refractory dysthymic disorder. RESULTS: In a series of 5 patients, chromium supplementation led to remission of dysthymic symptoms. Single-blind substitution of other dietary supplements in each of the patients demonstrated specificity of response to chromium supplementation. CONCLUSION: Preliminary observations suggest that chromium may potentiate antidepressant pharmacotherapy for dysthymic disorder. Controlled studies are indicated to test the validity of these initial observations.
