Personality disorders in veterans with posttraumatic stress disorder and depression.

Little is known about the frequency of the full-range of personality disorders in outpatients with concurrent posttraumatic stress disorder (PTSD) and depression, a common and oftentimes treatment-resistant combination in clinical practice. In a group therapy outcome study, Axis I and II diagnoses were assessed with the Structured Clinical Interview for DSM-IV and the Clinician-Administered PTSD Scale to select 115 male combat veterans with PTSD and depressive disorder. Within this sample, 52 (45.2%) had one or more personality disorders--most commonly paranoid (17.4%), obsessive-compulsive (16.5%), avoidant (12.2%), and borderline (8.7%)--and 19 (16.5%) had two or more. Documenting a substantial frequency of personality disorders is a first step in devising appropriate interventions for this treatment-resistant combination of disorders.

Comparison of bulimics, obese binge eaters, social phobics, and individuals with panic disorder on comorbidity across DSM-III-R anxiety disorders.

Eighty-two women, presenting as normal-weight bulimics, obese binge eaters, social phobics, and individuals with panic disorder, were compared on anxiety, depression, and substance abuse. All were administered the Anxiety Disorder Interview Schedule-Revised and completed the Michigan Alcohol Screening Test, Drug Abuse Screening Test, and Self-Consciousness Scale. A striking proportion of eating disorder subjects were comorbid for one or more anxiety disorders, the most frequent diagnoses being generalized anxiety disorder and social phobia. The results suggest that the place of anxiety in bulimia nervosa goes beyond that discussed within the context of the anxiety reduction model. Conflicting comorbidity findings among this and prior investigations are noted, however, and discussed in terms of the issue of differential diagnosis between eating and anxiety disorders.

Preadolescent children of substance-dependent fathers with antisocial personality disorder: psychiatric disorders and problem behaviors.

We compared psychiatric disorders and problem behavior scores in pre-adolescent children of fathers with alcohol or other drug dependence and ASP (SD+/ASP+), children whose fathers had substance dependence without ASP (SD+/ASP-), and children whose fathers were without either disorder (SD-/ASP-). SD+/ASP+ children showed elevated rates of major depression, conduct disorder, attention deficit hyperactivity disorder, oppositional defiant disorder, and separation anxiety disorder when compared to SD+/ASP- and SD-/ASP- children. SD+/ASP+ children had higher internalizing and externalizing problem behavior scores than the other two groups of children. The results suggest that SD+/ASP+ children are at significant risk for internalizing and externalizing psychopathology.

Mental disorders in a population sample with musculoskeletal disorders.

BACKGROUND: Studies using clinical and volunteer samples have reported an elevated prevalence of mood disorders in association with rheumatoid arthritis and osteoarthritis. Clinical studies using anxiety rating scales have reported inconsistent results, but studies using diagnostic instruments have reported that anxiety disorders may be even more strongly associated with arthritis than is depression. One study reported an association between lifetime substance use disorders and arthritis. METHODS: Data from iteration 1.2 of the Canadian Community Health Survey (CCHS) were used. This was a large-scale national Canadian health survey which administered the World Mental Health Composite International Diagnostic Interview to a sample of 36,984 subjects randomly selected from the national population. In the CCHS 1.2, subjects were asked whether they had been diagnosed by a health professional with arthritis or rheumatism. RESULTS: Subjects reporting arthritis or rheumatism had an elevated prevalence of mood, anxiety and substance use disorders. The strength of association resembled that seen in an omnibus category reporting any chronic condition, but was weaker than that seen with back pain or fibromyalgia. The effect of arthritis or rheumatism interacted with age, such that the odds ratios became smaller with increasing age. Mood and anxiety disorders, along with arthritis or rheumatism made an independent contribution to disability. CONCLUSION: Arthritis is associated with psychiatric morbidity in the general population, and this morbidity is seen across a variety of mental disorders. The strength of association is consistent with that seen in persons with other self-reported medical conditions.

Personality disorders in patients with somatisation disorder. A controlled study.

Twenty-five women with somatisation disorder (SD) were compared with matched patient controls for the presence of personality disorders. Personality was assessed with the Personality Assessment Schedule (PAS). Interviewers were unaware of the patients' diagnoses. All controls had DSM-III-R axis I diagnoses of depressive or anxiety disorders. The prevalence of personality disorders among patients with somatisation disorder was 72% compared with 36% among controls. Certain personality disorders, including passive-dependent, histrionic, and sensitive-aggressive, occurred significantly more often in the SD patients than controls.

Seasonal panic disorder: a possible variant of seasonal affective disorder.

The present communication concerns a 30 year-old female patient with panic disorder in whom panic attacks appeared to be seasonally-related. Characteristically, attacks were more frequent and severe during the months of October to May with spontaneous remissions during the months of June to September. Since 70% of patients with seasonal affective disorder (SAD), a variant of affective illness characterized by recurrent winter depressions with remissions in summer, suffer from anxiety disorders, we propose that seasonal panic disorder may be a variant of SAD. Since SAD is associated with phase delay of circadian rhythms, some forms of panic disorder may be related to phase instability of circadian rhythms. Moreover, since administration of artificial bright light therapy is currently the most effective treatment for SAD, it is suggested that patients with panic disorder should be questioned as to whether their symptoms are seasonally related. If a positive association is established, these patients should be offered treatment with light therapy prior to or coincident with the institution of pharmacotherapy.

[Anxiety neurosis--avoidant behavior--depression. A comparison between panic disorder and generalized anxiety disorder].

30 patients with "Anxiety disorder" were investigated with regard to their psychosocial experiences, their family history, the course of their illness, and their interpersonal relationships using a semi-structured interview. Patients with panic disorder significantly more frequently reported real fright of a parent than did patients with generalized anxiety disorder. Both groups showed a high degree of secondary depression and avoidance behavior in the course of their illness. Chronic anxiety was more frequent in patients with generalized anxiety disorder. The difference in the perception and judgement of anxiety clearly demonstrates the significance of attribution. Since the patient with panic disorder externalizes his anxiety, he has periods of complete remission, whereas the patient with generalized anxiety disorder internalizes his anxiety, thus experiencing it as an ego-syntonic feature, with which he cannot cope.

The impact of sexual and physical abuse on eating disordered and psychiatric symptoms: a comparison of eating disordered and psychiatric inpatients.

The authors compared rates of physical and sexual abuse in women with eating disorders (N = 102) and general psychiatric disorders (N = 49). Relationships between sexual abuse and severity of eating disordered and psychiatric symptoms were also examined. While high rates of sexual abuse were found in the eating disordered sample, these rates were not significantly higher than those found in the general psychiatric population. No relationship between a history of sexual abuse and severity of eating disordered symptoms was found. However, within the eating disordered group, sexually abuse subjects reported more severe psychiatric disturbances of an obsessive and phobic nature than nonabused subjects. These findings suggest that while sexually abusive experiences may be related to increased psychological distress, they do not serve to increase eating disordered symptomatology.

The impact of stress, fear of fatness, and panic disorder with agoraphobia on eating disorder symptomatology: a case study.

This case describes the interaction between an anxiety disorder and an eating disorder. It shows how the interplay between stress, fear of fatness, and panic disorder with agoraphobia changed a patient's eating disorder from bulimia nervosa to to an eating disorder focused on food restriction. Implications for the assessment and treatment of panic disorder with agoraphobia and an eating disorder focused on food restriction are discussed.

Frequency of DSM-III personality disorders in patients with panic disorder: comparison with psychiatric and normal control subjects.

Three clinical populations--panic disorder (n = 88), randomly selected outpatients (n = 82), and normal control subjects (n = 40)--were compared on three standardized DSM-III personality disorder instruments, the Structured Interview for DSM-III Personality Disorders (SIDP), the Millon Clinical Multiaxial Inventory (MCMI), and the Personality Diagnostic Questionnaire (PDQ). Significant differences were consistently found in presence of "any" personality disorder and DSM-III Cluster C (there were always more disorders in the outpatients). Logistic regression analysis revealed the important determinants predicting personality disorders, and therefore of differences between groups, were state depression, age, lifetime history of alcohol abuse, and presence of panic disorder.

Separation anxiety disorder, panic disorder, and school refusal.

Studies attest to the chronic nature of anxiety in youth. Consequently, there is a growing literature examining causative pathways to these disorders and efficacious treatments for them. This review examines separation anxiety disorder, a commonly occurring childhood anxiety disorder, and panic disorder, a more rare anxiety disorder in youth. Finally, school refusal, which may be tied to an internalizing or externalizing disorder or no disorder at all, is examined.

Channelopathies: ion channel disorders of muscle as a paradigm for paroxysmal disorders of the nervous system.

Some of the most common diseases in humans occur intermittently in people who are otherwise healthy and active. Such disorders include migraine headache, epilepsy, and cardiac arrhythmias. Because electrical signals are critical to the function of neurons, muscle cells, and heart cells, proteins that regulate electrical signaling in these cells are logical sites where abnormalities might lead to disease. All of these diseases have prominent genetic components. Difficulty in understanding these diseases arises from the complexity of the clinical phenotypes as well as from the genetic heterogeneity that is almost certain to exist. Therefore, early work in may laboratory was aimed at understanding the pathogenesis of rare disorders that are similar in their episodic nature. These disorders of muscle (the periodic paralyses), lead to attacks of weakness that occur intermittently in otherwise normal people. We, and others, have shown that hyperkalemic periodic paralysis (hyperKPP) and paramyotonia congenita (PC) result from mutations in a gene encoding a skeletal muscle sodium channel. We have also shown that hypokalemic periodic paralysis (hypoKPP) is caused by mutations in a gene encoding a voltage-gated calcium channel. The characterization of these diseases as channelopathies has served as a paradigm for other episodic disorders. One example is periodic ataxia, which results from mutations in voltage-gated potassium calcium channels. Long QT syndrome, an episodic cardiac dysrhythmia syndrome, is known to result from mutations in either voltage-gated sodium or potassium channels. We have recently mapped genes that cause a familial paroxysmal dyskinesia (non-kinesiogenic paroxysmal dystonia/choreoathetosis) in humans and a reflex epilepsy in mice. The similarities among all these disorders, including their episodic nature, precipitating factors, and therapeutic responses, are striking. Understanding gained from work in these rare monogenic episodic disorders is not only allowing characterization of the molecular and physiologic basis of these diseases, but may ultimately shed light on our understanding of the pathophysiology of more common and genetically complex disorders of the central nervous system.

Dual diagnosis in offenders with intellectual disability: setting research priorities: a review of research findings concerning psychiatric disorder (excluding personality disorder) among offenders with intellectual disability.

Studies of so-called 'dual diagnosis', i.e. intellectual disability (ID) with an additional psychiatric disorder, are reviewed with particular reference to offending behaviour. Because of the paucity of studies of psychopathology in offenders with ID, the present paper opens with studies of broader issues of psychopathology among people with ID, notably those with depression, schizophrenia, mild depressive disorder, other major psychotic disorders, anxiety/neurotic disorder, autistic spectrum disorders and attention deficit hyperactivity disorder. There follows a review of the most established and commonly used measurement scales for dual diagnosis in ID. The review then focuses directly on those studies which have looked at the issues of dual diagnosis among offenders with ID. In keeping with other reviews in this series, the latter studies are classified according to the same criteria. Based on this review, it is apparent that there are high-priority research questions which concern the extent and nature of psychopathology among offenders with ID, most notably those with autistic spectrum disorders.

Effect of therapeutic jaw exercise on temporomandibular disorders in individuals with chronic whiplash-associated disorders.

OBJECTIVE: The aim of this study was to investigate the effect of a specific therapeutic jaw exercise on the temporomandibular disorders of patients with chronic whiplash-associated disorders. MATERIAL AND METHODS: Ninety-four consecutive patients with whiplash-related conditions were referred to and accepted for a treatment period at a center for functional evaluation and rehabilitation during 2001-2002. The patients followed a program of physical therapy, occupational therapy, and pain management. At the start of their stay, they were examined by a physician specialized in rehabilitation medicine and also by a dentist who performed a functional examination of the stomatognathic system. Of the 93 patients who accepted participation in the study, 55 were diagnosed with temporomandibular disorders and chronic whiplash-associated disorders in accordance with the inclusion criteria. They were randomized into a jaw exercise group (n = 25), who performed specific therapeutic jaw exercises, and a control group (n = 30). Both groups undertook the whiplash rehabilitation program at the center. RESULTS: There were no inter- or intra-group differences in symptoms and signs of temporomandibular disorders at baseline, nor at the 3-week and 6-month follow-ups, except for an increase of maximum active mouth-opening capacity in the control group. CONCLUSIONS: In conclusion, the therapeutic jaw exercises, in addition to the regular whiplash rehabilitation program, did not reduce symptoms and signs of temporomandibular disorders in patients with chronic whiplash-associated disorders.

Psychological features are important predictors of functional gastrointestinal disorders in patients with eating disorders.

OBJECTIVE: Gastrointestinal symptoms that occur without evidence of structural gastrointestinal disease are a well-recognized feature of patients with eating disorders (EDs). Despite this, the spectrum and predictors of specific functional gastrointestinal disorders (FGIDs), documented using standardized and validated questionnaires, have received little attention. The aims of the study were to describe the prevalence and type of FGIDs in patients suffering from anorexia nervosa (AN), bulimia nervosa (BN) and eating disorders not otherwise specified (EDNOS), and to determine the relationships between psychological features, eating-disordered attitudes and behaviours, demographic characteristics and the type and number of FGIDs present. MATERIAL AND METHODS: A total of 101 consecutive female patients admitted to an eating disorder unit (AN 44%, BN 22%, EDNOS 34%, mean age 21 years) completed the Rome II modular questionnaire and a range of other validated self-reported questionnaires detailing illness history, psychological features and eating and exercise behaviour. RESULTS: The criteria for at least one FGID were fulfilled by 98% of the sample. The most prevalent FGIDs were irritable bowel syndrome (IBS: 52%), functional heartburn (FH: 51%), functional abdominal bloating (31%), functional constipation (FC: 24%), functional dysphagia (23%) and functional anorectal pain disorder (FAno: 22%); 52% of the sample satisfied the criteria for at least three coexistent FGIDs. Psychological variables (somatization, neuroticism, state and trait anxiety), age and binge eating were significant predictors of specific, and > or =3 coexistent FGIDs. Other disordered eating characteristics, including body mass index, were not predictors. CONCLUSIONS: In patients with EDs, specific psychological traits predict FGID type and the presence of multiple coexistent FGIDs. These findings support the role of specific psychological features as important contributors to certain FGIDs.

The Diagnostic Interview for Social and Communication Disorders: algorithms for ICD-10 childhood autism and Wing and Gould autistic spectrum disorder.

BACKGROUND: The Diagnostic Interview for Social and Communication Disorders (DISCO) is an interviewer-based schedule for use with parents and carers. In addition to its primary clinical purpose of helping the clinician to obtain a developmental history and description of the child or adult concerned, it can also be used to assist in providing a formal diagnostic category. METHOD: In this study we compared two algorithms based on the ninth revision of the schedule (DISCO 9). The algorithm for ICD-10 childhood autism comprised 91 individual, operationally defined items covering the behaviour outlined in the ICD-10 research criteria. The algorithm for the autistic spectrum disorder, as defined by Wing and Gould (1979), was based on 5 DISCO items that represented overarching categories of behaviour crucial for the diagnosis of autistic disorders. The aim of the study was to examine the implications for clinical diagnosis of these two different approaches. Parents of 36 children with clinical diagnoses of autistic disorder, 17 children with learning disability and 14 children with language disorders were interviewed by two interviewers. Algorithm diagnoses were applied to interview items in order to analyse the relationship between clinical and algorithm diagnoses and the inter-rater reliability between interviewers. RESULTS: Clinical diagnosis was significantly related to the diagnostic outputs for both algorithms. Inter-rater reliability was also high for both algorithms. The ICD childhood disorder algorithm produced more discrepant diagnoses than the Wing and Gould autistic spectrum algorithm. Analysis of the ICD-10 algorithm items and combination of items helped to explain the reason for these discrepancies. CONCLUSIONS: The results indicate that the DISCO is a reliable instrument for diagnosis when sources of information are used from the whole interview. It is particularly effective for diagnosing disorders of the broader autistic spectrum.

Distinctions between panic disorder and generalised anxiety disorder: clinical presentation.

Thirty-eight panic disorder and 48 generalised anxiety disorder subjects were asked to complete a number of questionnaires aimed at developing a general clinical picture of the two disorders. The results indicated that panic disorder is characterised by a sudden onset around the mid- to late-20s age group and is distinguished by symptoms which are chiefly hyperventilatory in nature and are accompanied by thoughts of serious physical or mental illness. Generalised anxiety disorder is characterised by a gradual onset of symptoms. Somatic symptoms associated with this disorder are generally accompanied by a realisation that the symptoms are the result of anxiety and are harmless. The two groups did not appear to differ greatly on a number of other scales except that the generalised anxiety disorder subjects scored higher on measures of manifest anxiety and social phobia.

[Separation anxiety disorder and eating disorders].

Separation anxiety disorder (SAD) is probably the most common anxiety disorder observed in childhood. If some studies suggest that SAD may increase the risk of anxiety and mood disorders in adolescents and young people, the outcome of childhood SAD remains unclear. Because of the high mental-eating disorders comorbidity, we performed a follow-back study in 81 young patients showing anorexia nervosa (AN) or bulimia nervosa (BN) according to DSM III-R criteria. The current and lifetime psychiatric histories were assessed using structured interviews (SADS-LA and SCID) and the psychopathological profile with the SCL-90. The results showed that about 20% of young patients with AN and BN had a past history of childhood SAD. This subgroup of patients significantly differed from the other (without childhood SAD) with respect to associated anxiety and depressive disorders. These data suggest a specific association between eating disorders and childhood SAD and show that epidemiologic investigations can be helpful for planning the prevention and treatment of eating disorders.
