Cross-cultural influences on psychogenic movement disorders - a comparative review with a Brazilian series of 83 cases

Objective

To describe the profile and presentation of a Brazilian series of psychogenic movement disorders (PMD) patients and to perform a comparative analysis with the previous series published worldwide.

Methods

A total of 83 patients with a clinical diagnosis of PMD were included. All patients were assessed and followed at the Movement Disorders Outpatient clinic from 2000 to 2008. Demographic, clinical, paraclinical, and treatment outcome data were collected using a standardized protocol. The Gupta & Lang criteria were used for the diagnosis of PMD.

Results

Seventy-three patients were females (87.95%), with mean age of onset of 39 ± 5.1 years. Tremor was the most frequent PMD, occurring in 42 (50.6%) patients followed by dystonia, in 27 (32.5%) patients. Cerebellar-like ataxia was seen in 3 patients (4.16%). Psychiatric co-morbidities were diagnosed in 67 (80.7%) of the patients. Thirty-five of the 58 patients (60.3%) who were managed and followed up for six months had some degree of improvement, including 22 patients (37.9%) with complete or almost complete remission.

Conclusion

In this series of patients with PMD, tremor and dystonia were most frequent PMD. Our results overlap those of the literature regarding most demographic and clinical findings, demonstrating the trans-cultural aspect of PMD.     

Prevalence of somatoform disorders in a psychiatric population: an Italian nationwide survey

The survey involved 50 centres comprising both hospital and community psychiatric care services throughout Italy. Overall, 2620 patients were recruited, and of those 2002 (76%) completed the Somatoform Disorders Schedule (SDS), a CIDI-derived interview. The NOS somatoform disorders (SDs) diagnosis appeared to be the most common (60%) (and they showed the highest number of co-morbid diagnoses), followed by pain disorders (8%). The prevalence of undifferentiated somatoform and hypochondriactal disorders was 1.6%: older age groups showed a tendency towards higher rates of the latter. In general, the study found that a significant percentage of patients with SDs are referred to psychiatric services, but mainly because of other psychopathological problems: in fact, somatic complaints are cross-sectionally present in different psychiatric nosological categories. This study also emphasizes some limitations of the current classification of SDs. Received: 9 August 1996 / Accepted: 14 July 1998     

The long-term course of autistic disorders: update on follow-up studies

The majority of children with autism show deviance and socially or psychiatrically handicapping conditions throughout life. Only a small proportion of those with classical childhood autism lead independent adult lives. Others, particularly those with ‘high-functioning’ autism and so-called Asperger syndrome will improve enough to live an independent adult life. The level of mental retardation and other comorbid conditions (such as medical syndromes and other neuropsychiatric disorders, including epilepsy) is important in predicting outcome. An IQ below 50 around school age predicts severe restriction of social and adaptive functioning in adult life. The absence of communicative speech at 5–6 years of age is indicative of a poorer long-term overall outcome. There is a clear co-variation between IQ and level of communication, but probably there is some prognostic factor in language development apart from this. Measures of flexibility and cognitive shifting abilities tend to be good predictors of social outcome in a few studies. There is a continued need for prospective, longitudinal studies of children with autism spectrum disorders, particularly in Asperger syndrome. The role of interventions of various kinds needs to be addressed in such studies.     

Validation of the Body Dysmorphic Disorder Questionnaire in a community sample of Swedish women

Body Dysmorphic Disorder (BDD) is characterized by a distressing and impairing preoccupation with a nonexistent or slight defect in appearance. Patients with the disorder present to both psychiatric and non-psychiatric physicians. A few studies have assessed BDD prevalence in the general population and have shown that the disorder is relatively common. To date, no BDD assessment instruments have been validated in the general population. Our aim was to validate a brief self-screening instrument, the Body Dysmorphic Disorder Questionnaire (BDDQ), in a female community sample. The BDDQ was translated into Swedish and filled out by 2891 women from a randomly selected community sample. The questionnaire was validated in a subsample of 88 women, using the Structured Clinical Interview for DSM-IV (SCID) together with clinical assessment as the gold standard. In the validation subsample, the BDDQ showed good concurrent validity, with a sensitivity of 94%, a specificity of 90% and a likelihood ratio of 9.4. The questionnaire can therefore be of value when screening for BDD in female populations.     

Functional impairment as a predictor of short-term symptom course in bipolar I disorder

Objectives:  Most prior research has focused on functional impairment as a consequence, rather than a predictor, of mood symptoms in bipolar disorder (BD). Yet the majority of this research has been cross-sectional, thus limiting conclusions regarding directionality of effects. Indeed, just as functional impairment may represent an important outcome of BD, it may also serve as a risk factor for future affective symptoms or episodes. Thus, the primary aim of this study was to evaluate functional impairment as a predictor of mood symptoms in BD.
Methods:  Ninety-two patients with bipolar I disorder, recruited from hospital settings, were administered the Modified Hamilton Rating Scale for Depression, Bech–Rafaelson Mania Scale, and UCLA Social Attainment Survey (SAS) at baseline and at four-month follow-up.
Results:  Overall, patients evidenced a moderate level of functional impairment at both time points. Whereas baseline functional impairment was not associated with subsequent manic symptoms, baseline functional impairment was significantly predictive of depressive symptom levels at four-month follow-up. When individual SAS subscales were evaluated, impaired romantic relationship functioning and activity involvement were each significantly predictive of subsequent depressive symptoms, whereas baseline peer functioning was not.
Conclusions:  The study results suggest that functional impairment may be predictive of subsequent depressive, but not manic, symptoms over a relatively short-term follow-up period. Future studies that evaluate illness course over longer follow-up periods would be useful to further clarify the potential bidirectional relationship between depression and functional impairment in BD.     

Aggressive course of cognitive impairment in multiple sclerosis: A new term for the management of patients

Multiple sclerosis (MS) can create different kinds of symptoms by involving different fields of the central nervous system. Cognitive impairment (CI) is one of the symptoms that can be caused by the onset of the disease and provide a change in the patient’s quality of life. Considering the course of the disease, CI usually worsens increasingly, and there is usually a severe CI in patients with end stage of MS. However, progressing CI can be so fast and severe in a few patients that it can disrupt the daily affairs of the individual. This paper plans to define the aggressive course of CIs in MS patients according to the reported cases. This definition explains that, the aggressive course of CI in MS patients happens in less than 5 years from the onset of the disease, and during this time, it causes dementia in the patient.     

Depression in the long-term course of schizophrenia

Abstract Depressive symptoms are quantitatively and qualitatively among the most important characteristics of schizophrenia. The following contribution reports on the prevalence of depression in 107 patients of the ABC schizophrenia study over 12 years after first hospital admission, looks into a preponderance of depression at certain stages of the illness and the predictive value of depressive symptoms for course and outcome. All but one of the 107 patients experienced one to 10 episodes of depressed mood between index assessment and long-term follow-up. In any month of the observation period about 30–35% of the patients presented at least one symptom of the depressive core syndrome (depressive mood, loss of pleasure, loss of interests, loss of self-confidence, feelings of guilt, suicidal thoughts/suicide attempt). Depressive symptoms are particularly frequent during a psychotic episode at a rate of approximately 50%. There were moderate but statistically significant correlations between the amount of depressive symptoms during a psychotic episode and the frequency of relapses, defined by hospital admissions as well as the total length of inpatient treatment. Depression occurring in the interval was not associated with an increased need for inpatient treatment.     

Patients with psychogenic non-epileptic seizures referred to a tertiary epilepsy centre: patient characteristics in relation to diagnostic delay

Objective

This clinical study examines patient and seizure characteristics of patients with psychogenic non-epileptic seizures (PNES) in a tertiary epilepsy centre. The main focus was whether a new subgroup of PNES patients emerged with a relatively short referral time and possible specific characteristics.

Methods

All PNES patients referred to a specialist program in our centre between mid 2007 and mid 2009 were consecutively included. This yielded a study cohort of 90 patients.

Results

The majority of the patients have a patient history with many medical symptoms and they were or had been in treatment by a medical specialist. Furthermore diffuse psychological/psychiatric symptoms and subsequent treatments are also remarkably common, in general without a clear psychological diagnosis. The average time between seizure onset and referral to an epilepsy centre is remarkably low (4.29 years). About 50% of the patients were referred within 2 years of seizure onset. This ‘active high speed referral group’ had significantly more previous psychological complaints, significantly more previous psychological/psychiatric treatments and a trend towards more previous medical investigations.

Conclusion

There seems to be a new subgroup of PNES patients with a short referral time, characterized by a more active attitude towards examination of the symptoms in combination with an active attitude to apply for treatment. However, the PNES cohort as a whole is characterized by having somatoform symptoms based on a process of somatization.     

Relationships of psychiatric disorders with sleep duration in an adult general population sample

The objective was to explore psychiatric disorders as potential predictors of sleep duration. A cross-sectional survey study with a probability sample of residents of a northern German area was carried out. There were 4075 study participants, aged 18–64 years, with a participation rate of 70.2%. Face-to-face in-home computer-aided interviews (Composite International Diagnostic Interview) provided diagnoses of nicotine and alcohol dependence, alcohol abuse, depressive, anxiety and somatoform disorders according to the Diagnostic and Statistical Manual of the American Psychiatric Association (DSM-IV), and included questions about sleep duration. Results show that subjects with a short sleep duration of 5 h or less had significantly increased odds ratios (OR) for current nicotine dependence (OR 1.9,; confidence interval, CI, 1.2–2.9), alcohol dependence (OR 2.6, CI 1.2–5.6), depressive disorder (OR 3.0, CI 1.7–5.4) or anxiety disorder (OR 2.1, CI 1.3–3.4) compared to individuals who never had the respective psychiatric disorder after adjustment for sex, age, and school education in a multinomial regression analysis. The conclusion is drawn that current nicotine or alcohol dependence, depressive, and anxiety disorders may add to short sleep duration in this random adult general population sample.     

Rates and predictors of remission in young women with specific phobia: A prospective community study

This prospective study reports rates and predictors of remission in young women with specific phobia. Data came from a prospective community study, in which German women (aged 18–25 years) completed an extended version of the Anxiety Disorders Interview Schedule (ADIS-IV-L) at two time points. Of the 137 women with specific phobia at baseline, 41.6% were partially remitted and an additional 19.0% were fully remitted at follow-up, defined as absence of any specific fears. A remitting course of specific phobia was predicted by residual protective factors at baseline, especially participants’ positive mental health and life satisfaction. Baseline levels of stress, coping skills, cognitive factors, psychopathology, and specific phobia characteristics did not predict remission. Results show that specific phobia in young women rarely takes a stable course at the full diagnostic threshold. The factors that influence remission of specific phobia are different from those that predict the incidence.     

Relationship of anxiety disorders, sleep quality, and functional impairment in a community sample

Background

Anxiety disorders and insomnia are each prevalent, impairing, and highly comorbid. However, little is known about whether specific types of sleep complaints are associated with specific anxiety disorders, and whether poor sleep has an additive effect on functional impairment in anxiety disorders.

Method

Data from the German Health Survey (GHS; N = 4181; ages 18-65) were utilized to examine relationships among anxiety disorders, sleep quality (assessed by the Pittsburgh Sleep Quality Inventory; PSQI), and functional impairment (assessed by the Medical Outcomes Scale Short Form; SF-36; and past-month disability days due to physical and emotional problems, respectively).

Results

Most anxiety disorders were significantly associated with global PSQI scores. Social phobia (AOR 3.95, 95% CI 1.73-9.04) and GAD (AOR 3.94, 95% CI 1.66-9.34) had the strongest relationships with global PSQI scores. Daytime dysfunction was the PSQI subscale most strongly associated with anxiety disorders, particularly GAD. Having a comorbid anxiety disorder and poor sleep was associated with significantly lower Mental Component Scores on the SF-36 than having an anxiety disorder alone (40.87 versus 43.87, p = .011) and with increased odds of one or more disability days due to emotional problems (AOR 2.72, 95% CI 1.35-5.48), even after controlling for sociodemographic factors and past-month mood and substance use disorders.

Conclusions

Most anxiety disorders are moderately associated with reduced sleep quality. Individuals with anxiety disorders and poor sleep experience significantly worse mental health-related quality of life and increased disability relative to those with anxiety disorders alone.     

Cognitive impairment and quality of life in long-term survivors of malignant brain tumors

Thirtysix long-term survivors following the treatment of a malignant supratentorial brain tumor were examined for cognitive functions and global level of autonomy. Eighteen patients were symptom-free (SF) and 18 had clinical and neuroradiological recurrence (RE). The control group included 30 healthy subjects. All subjects underwent a neuropsychological battery for general and specific cognitive functions. The level of autonomy was assessed by means of the Karnofsky Performance Scale (KPS) for oncological patients. SF patients showed less impairment than RE patients both at the tests, as well as on the KPS. The cognitive deficits were subclinical in most SF patients, the tests for attention, memory and word fluency being the most sensitive in detecting subtle dysfunctions. The association between tumor location and specific cognitive deficits was inconstant in both patient groups. The results suggest that even subtle cognitive deficits can prevent SF long-term survivors from returning to premorbid autonomy and occupations, and that neuropsychological tests may be used as complementary routine indicators of their quality of life. Furthermore, our data show that, in selected patients, combined treatments and therapeutic insistence do not necessarily have the same deleterious effects.

Sommario Trentasei pazienti, lungosopravviventi dopo il trattamento per un tumore sopratentoriale maligno, sono stati sottoposti ad und valutazione delle funzioni cognitive e del livello globale di autonomia. Diciotto pazienti erano asintomatici e 18 presentavano recidiva clinica e radiologica. Come gruppo di controllo sono stati esaminati 30 soggetti sani. Tutti i soggetti sono stati sottoposti ad una batteria neuropsicologica per la valutazione di funzioni cognitive generali e specifiche. Il livello di autonomia è stato definito mediante la scala di Karnofsky per pazienti oncologici. I pazienti asintomatici hanno mostrato una minore compromissione sia delle funzioni cognitive che del livello di autonomia rispetto a quelli con recidiva. I deficit cognitivi sono risultati modesti nella maggior parte dei pazienti asintomatici ed i test di attenzione, fluenza verbale e memoria sono apparsi i più sensibili nel rilievo di disfunzioni subcliniche. L'associazione tra sede del tumore e deficit cognitivi specifici è risultata incostante in entrambi i gruppi di pazienti. I risultati suggeriscono che deficit cognitivi anche lievi possono impedire il completo recupero dell'autonomia e delle attività premorbose nei lungosopravviventi asintomatici e che i test neuropsicologici possono fornire indici complementari nella valutazione routinaria della qualità di vita. I nostri dati inoltre mostrano che, in pazienti selezionati, l'insistenza terapeutica non induce necessariamente effetti deleteri.

Bone lead levels are associated with measures of memory impairment in older adults

Accumulating evidence suggests a link between lead exposure and memory impairment but assessments based on predictive and validated measures are lacking. We conducted a pilot study of 47 healthy subjects 55–67 years of age to examine associations between bone lead levels and 4 tests sensitive to the natural history of Mild Cognitive Impairment (MCI) and Alzheimer's disease (AD). These include three subtests of the Cambridge Neuropsychological Test Automated Battery (delayed match-to-sample, paired associates learning and spatial recognition memory) and the Montreal Cognitive Assessment Test. Bone lead concentrations were measured at the mid-shaft of the tibia and the calcaneus with K X-ray fluorescence. Higher tibial and calcaneal bone lead values were significantly (p < 0.05) associated with lower performance levels on delayed match-to-sample and paired associates learning in unadjusted analyses with Spearman rank correlation coefficients of about 0.4. Multiple linear regression analyses (i.e., least-squares means of cognitive test scores across tertiles of lead exposure) adjusted for age, education and smoking status continued to show an association of higher calcaneal lead levels with increasing memory impairments on delayed match-to-sample (p = 0.07). As might be expected, additional adjustment for history of hypertension reduced the strength of this association (p = 0.19). Given the demonstrated impact of lead exposure on hypertension and the vascular etiology of certain dementias, we speculate that hypertension could play a mediating role in the association between lead exposure and memory impairment.     

The course of cervical dystonia and patient satisfaction with long-term botulinum toxin A treatment

In 78 patients with idiopathic cervical dystonia (CD), we studied the course of the disease and the patients' satisfaction with long-term botulinum toxin A (BTX) treatment (median 5.5 years, range 1.5–10). On a seven-point scale ranging from excellent to worsening, the effect of treatment was scored as excellent or good by 52% of patients and moderate by 33%. The independent scores of the treating neurologists were excellent or good in 65% and moderate in 27%, respectively, and correlated well with the patients' scores. The 'Global Burden of Disease', as expressed on Visual Analog Scales (VAS, 0–10) before and at evaluation of treatment, was reduced by a median of 4 in individual patients. By combining these outcome measures, 67% of the patients were characterized as having a good effect, and 33% an unsatisfactory effect. This outcome (good or unsatisfactory effect) was independent of the severity of head deviation or complexity pattern of CD prior to treatment, the delay from onset to start of BTX treatment, or the number of treatments. The complexity pattern remained stable during treatment in 64% of the patients, became less complex in 19%, whereas 17% of the patients developed more complex patterns.     

Psychiatric disorders (DSM-III) and cognitive impairment among the elderly in a U.S. urban community

Results are presented on the current prevalence rates of psychiatric disorder in 2,588 non-institutionalized persons aged 65 and older who were drawn from a probability sample of New Haven, Connecticut, and 12 surrounding towns in South Central Connecticut. Based on the Diagnostic Interview Schedule (DIS), 6.7% of the respondents had a psychiatric diagnosis (DSM-III), and based on the Mini-Mental Status Exam (MMS), 3.4% had severe cognitive impairments during the past 6-month period. Therefore, more than 10% currently had either a psychiatric or a severe cognitive problem. Overall, these rates of psychiatric disorders are lower than those found in adult populations under age 65. As with younger samples, anxiety and affective disorders were among the most common psychiatric problems. The majority of elderly reported themselves in good emotional and physical health and felt they had sufficient finances to meet their needs. The rate of severe cognitive impairment did not increase until after age 79. Among those 80 years and older, cognitive impairments were more common in women than men, probably due to differential survival rates. Since less than 6% of the elderly sample are living in institutions these results among non-institutionalized elderly point to the relative psychiatric well-being of the majority of the elderly. However, in view of the longer life expectancy, the next decade will see an increase in the absolute number of persons with cognitive impairments.     

Predictors of the long-term course of comorbid PTSD: A naturalistic prospective study

Abstract

Objectives. The study examined the long-term course of posttraumatic stress disorder (PTSD) by analyzing rates of recurrence and the predictive value of comorbid psychiatric disorders and psychosocial functioning. Methods. This study is based on diagnostic assessments administered at intake and subsequent follow-up interviews over a period of 15 years in a sample of 90 anxiety-disordered patients with comorbid PTSD who participated in the Harvard Brown Anxiety Research project (HARP). Kaplan–Meier life table analysis revealed a 0.20 probability of full remission during the 15 years of follow-up. Results. Latent growth model (LGM) analysis revealed that the number of trauma exposures was a predictor of a worse course of PTSD but only during some intervals of the 15-year follow-up. Subjects with full social phobia were more likely to experience worsening of PTSD over time in comparison with subjects with less severe social phobia. Role functioning in the areas of household and employment was a significant predictor of a declining course of PTSD. Conclusions. These findings revealed the dynamic nature of the predictive value of traumatic experiences, the deleterious effect of social phobia and the long term effect of psychosocial functioning on the course of PTSD. Implications for treatment planning and development of interventions for PTSD are discussed.     

A community study in Cornwall UK of sudden unexpected death in epilepsy (SUDEP) in a 9-year population sample

PurposeEpilepsy-related death, particularly sudden unexpected death in epilepsy (SUDEP), is underestimated by healthcare professionals. One argument that physicians use to justify the failure to discuss SUDEP with patients and their families is that there is a lack of evidence for any protective interventions. However, there is growing evidence of potentially modifiable risk factors for SUDEP; although large-scale trials of interventions are still lacking. We determined the main risk factors associated with SUDEP in a comprehensive community sample of epilepsy deaths in Cornwall UK from 2004 to 2012.MethodsWe systemically inspected 93 cases of all epilepsy and epilepsy associated deaths which occurred in Cornwall between 2004 and 2012 made available to us by the HM Cornwall coroner. These are the deaths where epilepsy was a primary or a secondary cause.Results48 cases met the criteria for SUDEP and we elicited associated relevant risk factors. Many findings from our study are comparable to what has been reported previously. New points such as most of the population had increase in either or both seizure frequency/intensity within six months of death and majority did not have an epilepsy specialist review in the last one year to demise were noted.ConclusionThis study is the first epidemiological study in England occurring in a whole population identifying systemically all deaths and the first large scale review in UK of SUDEP deaths since 2005. Being a community based study a key issue which was highlighted was that in the SUDEPs examined many might have been potentially preventable.     

Incidence of depression in a medical long-term care facility: Findings from a restricted sample of new admissions

The prevalence rate of depression in medical long-term care facilities is high but varies over a large range. One source of variation may be differences in the underlying incidence rates. A cohort of 104 new admissions was followed for one year and showed and incidence rate of approximately 14%. This rate is comparable to the only other published study and suggests that incidence rates may be more uniform than expected from the range of prevalence reports.
