The Nottingham Study of Neurotic Disorder: predictors of 12-year outcome of dysthymic, panic and generalized anxiety disorder.

BACKGROUND: Controlled prospective studies of the simultaneous long-term outcome of several mental disorders are rare. This study sought to determine if there were important differences between the outcome of anxiety and depressive disorders after 12 years and to examine their main predictors. METHOD: A cohort of 210 people seen in general practice psychiatric clinics with a DSM-III diagnosis of generalized anxiety disorder (71), panic disorder (74), or dysthymic disorder (65), including combined anxiety-depressive disorder (cothymia) (67) was followed up after 12 years. Interview assessments of symptoms, social functioning and outcome were made, the latter using a new scale, the Neurotic Disorder Outcome Scale. Seventeen baseline predictors were also examined. RESULTS: Data were obtained from 201 (96 %) patients, 17 of whom had died. Only 73 (36 %) had no DSM diagnosis at the time of follow-up. Using univariate and stepwise multiple linear regression those with cothymia, personality disorder, recurrent episodes and greater baseline self-rated anxiety and depression ratings had a worse outcome than others; initial diagnosis did not contribute significantly to outcome and instability of diagnosis over time was much more common than consistency. CONCLUSION: Only two out of five people with the common neurotic disorders have a good outcome despite alleged advances in treatment. Those with greater mood symptoms and pre-morbid personality disorder have the least favourable outcome. It is suggested that greater attention be paid to the concurrent treatment of personality disorder and environmental factors rather than symptoms as these may be the real cause of apparent treatment resistance.

Anxiety disorders and tic severity in juveniles with Tourette's disorder.

OBJECTIVE: It was hypothesized that comorbidity with anxiety disorders would predict tic severity in youths with Tourette's disorder (TD). METHOD: Subjects were 190 youths meeting DSM-III-R diagnostic criteria for TD who were consecutively referred to a pediatric psychopharmacology program between 1994 and 1997. Subjects were initially evaluated with a clinical interview and the Schedule for Affective Disorders and Schizophrenia for School-Age Children-Epidemiologic version. Statistical analysis used t tests, chi 2 tests, and logistic regression analysis. RESULTS: One hundred thirty-four subjects were classified as mild/moderate and 56 as severe TD cases. No meaningful differences were found in socioeconomic status, gender distribution, or age at onset of TD between the 2 groups. The 2 groups could not be differentiated by the presence of comorbid mood or disruptive behavior disorders including attention-deficit hyperactivity disorder. Although obsessive-compulsive disorder (OCD) was overrepresented among the severe TD cases, the difference failed to reach statistical significance. Excluding social and simple phobias, all other anxiety disorders were more clearly overrepresented among subjects with severe TD; separation anxiety disorder most robustly predicted tic severity, irrespective of the presence of OCD or other anxiety disorders. CONCLUSION: Findings suggest that non-OCD anxiety disorders in general and separation anxiety disorder in particular may be significantly associated with tic severity in referred TD patients.

Children with schizophrenia-spectrum disorders: thought disorder and communication problems in a family interactional context.

Thought disorder and communication patterns during an interactional task were examined in families of children with schizophrenia-spectrum disorders (schizophrenia and schizotypal personality disorder), depressed children, and normal controls. Children with schizophrenia-spectrum disorders showed significantly more thought disorder than their normal peers; levels of thought disorder among depressed children fell between those observed in the other two groups but did not differ significantly from either of them. Similarly, mothers of children with schizophrenia-spectrum disorders showed more thought disorder than mothers of normal control children but did not differ from mothers of depressed children. Children with schizotypal personality disorder did not differ from children with schizophrenia. These findings demonstrate that the thought disorder present in childhood-onset schizophrenia and schizotypal personality disorders is manifest in an important social context, the family.

The comorbidity of borderline personality disorder and other DSM-III-R axis II personality disorders.

OBJECTIVE: This study examines the comorbidity of DSM-III-R borderline personality disorder and the other axis II personality disorders. The extent and direction of overlap provides a measure of the clarity of its diagnostic boundaries and descriptive validity. METHOD: In 110 outpatients without concurrent major axis I conditions, axis II diagnoses were assessed in semistructured format and all DSM-III-R personality disorder criteria were rated. Multiple diagnoses were recorded. RESULTS: Twenty-two patients (20%) met criteria for borderline personality disorder; 18 (82%) had at least one additional personality disorder diagnosis. Using measures of frequencies and intercorrelation coefficients, the authors found that overlap was extensive and not confined to any one of the three designated axis II clusters. Factor analysis revealed 1) a group containing borderline personality disorder with paranoid, histrionic, narcissistic, antisocial, and passive-aggressive personality disorders and 2) another grouping of schizoid, schizotypal, avoidant, obsessive-compulsive, and self-defeating personality disorders. CONCLUSIONS: Borderline personality disorder appears to constitute a broad, heterogeneous category with unclear boundaries that embraces a general personality disorder concept. Both further refinement of the borderline personality disorder construct and investigation into alternative models to the DSM-III-R axis II classification system are suggested.

Bipolar disorder at prospective follow-up of adults who had prepubertal major depressive disorder.

OBJECTIVE: The authors' goal was to conduct an adult follow-up of subjects who had participated in a study of nortriptyline for childhood depression. METHOD: The study group represented 100 (90. 9%) of the original 110 subjects and included 72 subjects who had a prepubertal diagnosis of major depressive disorder and 28 normal comparison subjects. Subjects were assessed with semistructured research interviews given by research nurses who were blind to the subjects' original diagnoses. RESULTS: In the original study, the mean age of the children with prepubertal major depressive disorder was 10.3 years (SD=1.5); at adult follow-up the mean age of these subjects was 20.7 years (SD=2.0). At follow-up, significantly more of the subjects who had prepubertal diagnoses of major depressive disorder (N=24 [33.3%]) than normal comparison subjects (none) had bipolar I disorder. Subjects who had prepubertal diagnoses of major depressive disorder also had significantly higher rates of any bipolar disorder than normal subjects (48.6% [N=35] versus 7.1% [N=2]), major depressive disorder (36.1% [N=26] versus 14.3% [N=4]), substance use disorders (30.6% [N=22] versus 10.7% [N=3]), and suicidality (22.2% [N=16] versus 3.6% [N=1]). Parental and grandparental mania predicted bipolar I disorder outcomes. CONCLUSIONS: High rates of switching to mania have implications for the treatment of depressed children. The authors discuss the reasons for their finding a higher rate of bipolar disorder in this outcome study than was found in the one other adult outcome study of prepubertal major depressive disorder.

Association of rapid mood switching with panic disorder and familial panic risk in familial bipolar disorder.

OBJECTIVE: Comorbid bipolar and panic disorders aggregate in families. A phenotypic trait shared by both disorders is the sudden shift in affect observed in panic attacks and some rapid cycling states. The authors investigated whether comorbidity of bipolar disorder and panic disorder is associated with rapid mood switching in families with a high rate of bipolar disorder. METHOD: Six hundred six subjects with bipolar disorder from the NIMH Bipolar Disorder Genetics Initiative were included in the study. Logistic regression analysis was used to analyze rapid mood switching as a function of panic disorder diagnosis, sex, and familial risk for panic. RESULTS: Familial panic and the diagnosis of panic disorder in an individual subject increased the odds for rapid mood switching. The familial effect persisted when individuals with panic disorder were excluded from the analysis. CONCLUSIONS: Panic and rapid mood switching occurring together in familial bipolar disorder may define a useful subphenotype for future studies.

Gambling disorders among homeless persons with substance use disorders seeking treatment at a community center.

OBJECTIVES: Epidemiological research suggests that homelessness is a risk factor for elevated levels of psychiatric comorbidity and other health risks. This study examined the prevalence of disordered gambling and its association with treatment of psychiatric and substance use disorders among a cohort of homeless people seeking treatment at a community services program. METHODS: Between 1998 and 2000, intake workers evaluated the level of gambling disorder among 171 consecutive homeless persons with substance use disorders who sought treatment at the Moving Ahead Program in Boston. Program staff administered the DSM-IV subscale of the Massachusetts Gambling Screen at intake. RESULTS: The prevalence rates of level 2 and level 3 gambling disorders were 12.8 percent and 5.5 percent, respectively. These rates are higher than that of the general adult population but comparable to those of other patients with substance use disorders and psychiatric diagnoses. Program participants with level 3 gambling disorders had been homeless more often and at a younger age and had had less substance abuse treatment and more psychiatric treatment than participants with level 1 or level 2 gambling disorders. Participants with level 2 gambling disorders had been homeless more often and for a longer duration than participants without gambling disorders. CONCLUSIONS: These findings should encourage clinicians working with homeless people to screen for gambling-related problems and disorders.

[Eating disorders and personality disorders--possible interactions and their therapeutic implications].

Personality disorders are defined by a characteristic and enduring pattern of behaviour and inner experience that deviates distinctly from culturally defined norms. Examples include social insecurity or even distrust leading to withdrawal, or patterns of impulsiveness, affective instability or, possibly, self-harm. Personality disorders are distinct from other psychiatric disorders primarily by their enduring character. The prevalence of personality disorders among patients with eating disorders depends on population characteristics. In a specialised outpatient clinic that serves a defined catchment area, nearly one third of patients will fulfill the diagnostic criteria for a personality disorder. Hospitalized patients or patients in more specialised units will surely show a considerably higher prevalence. Several modes of interaction between eating disorders and personality disorders could be hypothesized. The treatment of patients with eating disorder should take into account the subgroup with comorbid personality pathology and evaluation and treatment should be planned accordingly, though this requires time and expertise. The issue should also be acknowledged in primary health care and attention be paid to symptoms of eating disorder also in cases in which symptoms of a personality disorder are more pronounced.

Posttraumatic stress disorder in primary care with special reference to personality disorder comorbidity.

BACKGROUND: Posttraumatic stress disorder (PTSD) is a common and disabling disturbance in primary care. Few studies have been carried out in primary care samples and none have taken into consideration the association between PTSD and personality disorder. AIM: To describe prevalence and risk factors of PTSD and its comorbidity with personality disorder. SETTING: General practice centre in Valencia (Spain). METHOD: Patients who had experienced at least one traumatic event in their lives were selected from a random sample attending a primary healthcare centre in Valencia and blindly assessed by trained professionals. Patients suffering from PTSD were compared with those who were not. PTSD and personality disorder diagnoses were established using CIDI and SCID-II interviews respectively. Sex, age at the time of experiencing trauma, frequency, multiplicity and type of trauma, dissociative symptoms, personality disorder and severity of PTSD were subjected to multivariate analysis to estimate the probability of developing PTSD and its duration. RESULTS: Life prevalence rate was 14% and current prevalence 9%. Dissociative symptoms and personality disorder were significantly associated with PTSD. Cluster analysis based on age, frequency and type of trauma revealed the existence of one subgroup composed mainly of women who had experienced frequent body-contact trauma at an early age, developed severe PTSD and suffer from a variety of personality disorders, particularly paranoid personality disorder. Time to the complete disappearance of symptoms was only explained by the initial severity of PTSD. CONCLUSION: PTSD is a frequent disorder in general practice and it is often associated with personality disorder. Women who experienced high frequency body-contact traumatic events at an early age often suffer from personality disorder and present a particularly severe form of PTSD deserving referral to specialised care.

[Follow-up of psychiatric disorders and specific developmental delay disorders in special education students].

In a prospective longitudinal study 72 children who were attending a special school for children with learning disabilities in Erlangen were examined in 1990 and again in 1992/93. At the first examination the children's mean age was 7 years 1 month and at the second 8 years 10 months. The sample contained many more boys than girls. Reported here are the findings on the course of the psychiatric disorders and the specific developmental disorders of speech and language and motor function. There was a marked decrease in the prevalence of psychiatric disorders. Of the 17 children with a psychiatric disorder at follow-up, 13 (76%) also had a disorder at the start of the study and of the 23 with a psychiatric disorder at the start 13 (57%) still had a disorder at follow-up. Children with enuresis and those with disturbances of activity or attention had the best prognosis. The special school had a positive effect on conduct. The prevalence of specific developmental disorders also decreased over the two-year period. As expected, specific speech articulation disorders had the best prognosis. All other disorders had a poor prognosis. Increases in prevalence were mainly the result of different cutoff points for a given diagnosis at different ages. The high number of specific disorders of motor function at both time points is especially noteworthy.

Obsessive-compulsive disorder and body dysmorphic disorder: a comparison of clinical features.

Body dysmorphic disorder (BDD) is currently classified as a somatoform disorder in DSM-IV, but has been long noted to have some important similarities with obsessive-compulsive disorder (OCD). In addition, BDD and OCD have been often reported to be comorbid with each other. In the present study, we compared demographic characteristics, clinical features and psychiatric comorbidity in patients with OCD, BDD or comorbid BDD-OCD (34 subjects with BDD, 79 with OCD and 24 with BDD-OCD). We also compared the pattern of body dysmorphic concerns and associated behaviors in BDD patients with or without OCD comorbidity. In our sample, BDD and OCD groups showed similar sex ratio. Both groups with BDD and BDD-OCD were significantly younger, and experienced the onset of their disorder at a significantly younger age than subjects with OCD. The two BDD groups were also less likely to be married, and more likely to be unemployed and to have achieved lower level degree, than OCD subjects even when controlling for age. The three groups were significantly different in the presence of comorbid bulimia, alcohol-related and substance-use disorders, BDD-OCD patients showing the highest rate and OCD the lowest. BDD-OCD reported more comorbid bipolar II disorder and social phobia than in the other two groups, while generalized anxiety disorder was observed more frequently in OCD patients. Patients with BDD and BDD-OCD were similar as regards the presence of repetitive BDD-related behaviors, such as mirror-checking or camouflaging. Both groups also did show a similar pattern of distribution as regards the localization of the supposed physical defects in specific areas of the body. The only significant difference concerned the localization in the face, that was more frequent in the BDD group. Our results do not contradict the proposed possible conceptualization of BDD as an OCD spectrum disorder. However, BDD does not appear to be a simple clinical variant of OCD and it seems to be also related to social phobia, mood, eating and impulse control disorders. The co-presence of BDD and OCD features appears to possibly individuate a particularly severe form of the syndrome, with a greater load of psychopathology and functional impairment and a more frequent occurrence of other comorbid mental disorders.

Does temperamental instability support a continuity between bipolar II disorder and major depressive disorder?

BACKGROUND: The current categorical split of mood disorders in bipolar disorders and depressive disorders has recently been questioned. Two highly unstable personality features, i.e. the cyclothymic temperament (CT) and borderline personality disorder (BPD), have been found to be more common in bipolar II (BP-II) disorder than in major depressive disorder (MDD). According to Kraepelin, temperamental instability was the "foundation" of his unitary view of mood disorders. STUDY AIM: The aim was to assess the distributions of the number of CT and borderline personality items between BP-II and MDD. Finding no bi-modal distribution (a "zone of rarity") of these items would support a continuity between the two disorders. METHODS STUDY SETTING: an outpatient psychiatry private practice. Interviewer: A senior clinical and mood disorder research psychiatrist. PATIENT POPULATION: A consecutive sample of 138 BP-II and 71 MDD remitted outpatients. Assessment instruments: The structured clinical interview for DSM-IV Axis I Disorders-Clinician Version (SCID-CV), the SCID-II Personality Questionnaire for self-assessing borderline personality traits (BPT) by patients, the TEMPS-A for self-assessing CT by patients. Interview methods: Patients were interviewed with the SCID-CV to diagnose BP-II and MDD, and then patients self-assessed the questions of the Personality Questionnaire relative to borderline personality, and the questions of the TEMPS-A relative to CT. As clinically significant distress or impairment of functioning is not assessed by the SCID-II Personality Questionnaire, a diagnosis of BPD could not be made, but BPT could be assessed (i.e. all BPD items but not the impairment criterion). The distribution of the number of CT and BPT items was studied by Kernel density estimate. RESULTS: CT and BPT items were significantly more common in BP-II versus MDD. The Kernel density estimate distributions of the number of CT and BPT items in the entire sample had a normal-like shape (i.e. no bi-modality). CONCLUSIONS: The expected finding, on the basis of previous studies and of the present sample features, was a clustering of CT and BPT items on the BP-II side of the curves. Instead, no bi-modality was present in the distributions of the number of CT and BPT items in the entire sample, showing a normal-like shape. By using the bi-modality approach, a continuity between BP-II and MDD seems supported, questioning the current categorical splitting of BP-II and MDD based on classic diagnostic validators.

Co-occurrence of 12-month mood and anxiety disorders and personality disorders in the US: results from the national epidemiologic survey on alcohol and related conditions.

The objective of this study was to determine the prevalence and co-occurrence of DSM-IV personality disorders (PDs) among individuals with current DSM-IV mood and anxiety disorders in the US population and among individuals who sought treatment for such mood or anxiety disorders. Face-to-face interviews were conducted with 43,093 individuals, 18 years and older, in the National Institute on alcohol abuse and alcoholism's 2001-2002 National epidemiologic survey on alcohol and related conditions (NESARC). Odds ratios (ORs) were calculated to determine the prevalence and associations between current DSM-IV axis I and axis II disorders. Associations between mood, anxiety and PDs were all positive and statistically significant. Avoidant and dependent PDs were more strongly related to mood and anxiety disorders than other PDs. Associations between obsessive-compulsive PD and mood and anxiety disorders were significant, but much weaker. Paranoid and schizoid PDs were most strongly related to dysthymia, mania, panic disorder with agoraphobia, social phobia and generalized anxiety disorder, while histrionic and antisocial PDs were most strongly related to mania and panic disorder with agoraphobia. Results of this study highlight the need for further research on overlapping symptomatology, factors giving rise to the associations and the treatment implications of these disorders when comorbid.

Associations in the longitudinal course of body dysmorphic disorder with major depression, obsessive-compulsive disorder, and social phobia.

Body dysmorphic disorder (BDD) is an impairing and relatively common disorder that has high comorbidity with certain Axis I disorders. However, the longitudinal associations between BDD and comorbid disorders have not previously been examined. Such information may shed light on the nature of BDD's relationship to putative "near-neighbor" disorders, such as major depression, obsessive-compulsive disorder (OCD), and social phobia. This study examined time-varying associations between BDD and these comorbid disorders in 161 participants over 1-3 years of follow-up in the first prospective longitudinal study of the course of BDD. We found that BDD had significant longitudinal associations with major depression--that is, change in the status of BDD and major depression was closely linked in time, with improvement in major depression predicting BDD remission, and, conversely, improvement in BDD predicting depression remission. We also found that improvement in OCD predicted BDD remission, but that BDD improvement did not predict OCD remission. No significant longitudinal associations were found for BDD and social phobia (although the results for analyses of OCD and social phobia were less numerically stable). These findings suggest (but do not prove) that BDD may be etiologically linked to major depression and OCD, i.e., that BDD may be a member of both the putative OCD spectrum and the affective spectrum. However, BDD does not appear to simply be a symptom of these comorbid disorders, as BDD symptoms persisted in a sizable proportion of subjects who remitted from these comorbid disorders. Additional studies are needed to elucidate the nature of BDD's relationship to commonly co-occurring disorders, as this issue has important theoretical and clinical implications.

The relationship of obsessive-compulsive disorder to possible spectrum disorders: results from a family study.

BACKGROUND: The familial relationship between obsessive-compulsive disorder (OCD) and "obsessive-compulsive spectrum" disorders is unclear. This study investigates the relationship of OCD to somatoform disorders (body dysmorphic disorder [BDD] and hypochondriasis), eating disorders (e.g., anorexia nervosa and bulimia nervosa), pathologic "grooming" conditions (e.g., nail biting, skin picking, trichotillomania), and other impulse control disorders (e.g., kleptomania, pathologic gambling, pyromania) using blinded family study methodology. METHODS: Eighty case and 73 control probands, as well as 343 case and 300 control first-degree relatives, were examined by psychiatrists or Ph.D. psychologists using the Schedule for Affective Disorders and Schizophrenia-Lifetime Anxiety version. Two experienced psychiatrists independently reviewed all diagnostic information and made final consensus diagnoses using DSM-IV criteria. RESULTS: Body dysmorphic disorder, hypochondriasis, any eating disorder, and any grooming condition occurred more frequently in case probands. In addition, BDD, either somatoform disorder, and any grooming condition occurred more frequently in case relatives, whether or not case probands also had the same diagnosis. CONCLUSIONS: These findings indicate that certain somatoform and pathologic grooming conditions are part of the familial OCD spectrum. Though other "spectrum" conditions may resemble OCD, they do not appear to be important parts of the familial spectrum.

Associations in the course of personality disorders and Axis I disorders over time.

In this study, the authors examined time-varying associations between schizotypal (STPD), borderline (BPD), avoidant (AVPD), or obsessive-compulsive (OCPD) personality disorders and co-occurring Axis I disorders in 544 adult participants from the Collaborative Longitudinal Personality Disorders Study. The authors tested predictions of specific longitudinal associations derived from a model of crosscutting psychobiological dimensions (L. J. Siever & K. L. Davis, 1991) with participants with the relevant Axis I disorders. The authors assessed participants at baseline and at 6-, 12-, and 24-month follow-up evaluations. BPD showed significant longitudinal associations with major depressive disorder and posttraumatic stress disorder. AVPD was significantly associated with anxiety disorders (specifically social phobia and obsessive-compulsive disorder). Two of the four personality disorders under examination (STPD and OCPD) showed little or no association with Axis I disorders.

Sedative use disorders in opiate-dependent patients: association with psychiatric and other substance use disorders.

Opiate-dependent patients (N = 231), classified by sedative disorder status, were characterized according to DSM-IIIR on substance use and psychiatric disorders. Twenty-one percent currently (CUR+) had sedative use disorder, 39% had a history (HX+) of sedative use disorder, and 40% had no history (HX-) of this disorder. Several group differences were found. The HX+ and CUR+ groups had more lifetime drug use disorders (means = 4.5 and 4.3 vs. 3.2 in the HX- group), including alcohol, cannabis, stimulants, cocaine, and hallucinogens. In contrast, other psychiatric disorders (e.g., anxiety and depression) were low in prevalence and did not differ across groups, with the exception of a higher prevalence of antisocial personality disorder in the HX+ and CUR+ groups (39.6% and 38.5% vs. 17.9% in HX- group). The results suggest that sedative use disorder is related more to a severe spectrum of multiple substance abuse than it is to self-medication of underlying mood or anxiety disorders.

Personality and personality disorders among patients with major depression in combination with dysthymic or cyclothymic disorders.

Personality traits and personality disorders in 298 consecutive outpatients with pure major depression, major depression with dysthymic or cyclothymic disorder, pure dysthymic or cyclothymic disorder and other disorders were investigated. Patients with dysthymic or cyclothymic disorders alone or in combination with major depression showed more self-doubt, insecurity, sensitivity, compliance, rigidity and emotional instability. They were more schizoid, schizotypal, borderline and avoidant according to MCMI and had a higher prevalence of DSM-III Axis II diagnoses, and more borderline, avoidant, and passive-aggressive personality disorders, as measured by SIDP. All in all, dramatic and anxious clusters of personality disorders were more frequent among patients with dysthymic-cyclothymic disorders in addition to major depression than among patients with major depression only. The findings elucidated the close connection between the more chronic affective disorders and the personality disorders, irrespective of any concomitant diagnosis of major depression.
