Background Auditory verbal hallucinations (AVH) in patients with borderline personality disorder (BPD) are frequently claimed to be brief, less severe and qualitatively different from those in schizophrenia, hence the term 'pseudohallucinations'. AVH in BPD may be more similar to those experienced by healthy individuals, who experience AVH in a lower frequency and with a more positive content than AVH in schizophrenia. In this study the phenomenology of AVH in BPD patients was compared to that in schizophrenia and to AVH experienced by non-patients. Method In a cross-sectional setting, the phenomenological characteristics of AVH in 38 BPD patients were compared to those in 51 patients with schizophrenia/schizoaffective disorder and to AVH of 66 non-patients, using the Psychotic Symptom Rating Scales (PSYRATS). Results BPD patients experienced AVH for a mean duration of 18 years, with a mean frequency of at least daily lasting several minutes or more. The ensuing distress was high. No differences in the phenomenological characteristics of AVH were revealed among patients diagnosed with BPD and those with schizophrenia/schizoaffective disorder, except for 'disruption of life', which was higher in the latter group. Compared to non-patients experiencing AVH, BPD patients had higher scores on almost all items. Conclusions AVH in BPD patients are phenomenologically similar to those in schizophrenia, and different from those in healthy individuals. As AVH in patients with BPD fulfil the criteria of hallucinations proper, we prefer the term AVH over 'pseudohallucinations', so as to prevent trivialization and to promote adequate diagnosis and treatment. © 2012 Cambridge University Press.

Objective: To study the course and outcome of patients with eating disorder detected in primary care. Method: General practitioners (GP's) provided information on the course and outcome of eating disorders in patients (n = 147) diagnosed with anorexia nervosa (AN) or bulimia nervosa (BN) identified during a Dutch nationwide primary care-based incidence study. The research team determined the outcome based on the data provided by the GP's. The mean duration of the follow-up was 4.8 years. Results: About 57% of the patients initially diagnosed with AN and 61% of those diagnosed with BN were fully recovered. AN binge/purge subtype (ANBP) demonstrated the most extended median survival time of all diagnostic subgroups (the point at which half of the group has reached full recovery). Diagnostic crossover was low. A younger age at detection predicted recovery at outcome for AN and BN. One patient (AN) died. Discussion: The results of this study on differences in outcome and low crossover support the diagnostic distinction between AN and BN in the DSM-IV. Early detection is of major importance for a favorable outcome. © 2009 by Wiley Periodicals, Inc.

Objective: Repetitive transcranial magnetic stimulation (rTMS) is a safe treatment method with few side effects. However, efficacy for various psychiatric disorders is currently not clear. Data sources: A literature search was performed from 1966 through October 2008 using PubMed, Ovid Medline, Embase Psychiatry, Cochrane Central Register of Controlled Trials, Cochrane Database of Systematic Reviews, Database of Abstracts of Reviews of Effects, and PsycINFO. The following search terms were used: transcranial magnetic stimulation, TMS, repetitive TMS, psychiatry, mental disorder, psychiatric disorder, anxiety disorder, attention-deficit hyperactivity disorder, bipolar disorder, catatonia, mania, depression, obsessive-compulsive disorder, psychosis, posttraumatic stress disorder, schizophrenia, Tourette's syndrome, bulimia nervosa, and addiction. Study selection: Data were obtained from randomized, sham-controlled studies of rTMS treatment for depression (34 studies), auditory verbal hallucinations (AVH, 7 studies), negative symptoms in schizophrenia (7 studies), and obsessive-compulsive disorder (OCD, 3 studies). Studies of rTMS versus electroconvulsive treatment (ECT, 6 studies) for depression were meta-analyzed. Data extraction: Standardized mean effect sizes of rTMS versus sham were computed based on pretreatment-posttreatment comparisons. Data synthesis: The mean weighted effect size of rTMS versus sham for depression was 0.55 (P < .001). Monotherapy with rTMS was more effective than rTMS as adjunctive to antidepressant medication. ECT was superior to rTMS in the treatment of depression (mean weighted effect size -0.47, P = .004). In the treatment of AVH, rTMS was superior to sham treatment, with a mean weighted effect size of 0.54 (P < .001). The mean weighted effect size for rTMS versus sham in the treatment of negative symptoms in schizophrenia was 0.39 (P = .11) and for OCD, 0.15 (P = .52). Side effects were mild, yet more prevalent with high-frequency rTMS at frontal locations. Conclusions: It is time to provide rTMS as a clinical treatment method for depression, for auditory verbal hallucinations, and possibly for negative symptoms. We do not recommend rTMS for the treatment of OCD. © Copyright 2010 Physicians Postgraduate Press, Inc.

Aim The aim of the study was to collect detailed data on behavioural, adaptive, and psychological functioning in 10 individuals with Pitt-Hopkins syndrome (PTHS), with specific attention to manifestations of autism spectrum disorder (ASD). Method The participants (four females, six males), residing in the Netherlands and Belgium, were ascertained through the Dutch national PTHS support group. Median age of participants was 10 years, the age range was between 32 and 289 months. They underwent psychiatric examinations and neuropsychological measurements using a comprehensive assessment battery. Additionally, parental information was gathered through standardized interviews and questionnaires. Findings were compared with those from the literature. Results All participants showed profound intellectual disability, amiable demeanour with minimal maladaptive behaviours, severe impairments of communication and language, and intense, frequent motor stereotypies. Impairments in all participants were beyond what would be expected for cognitive abilities, fitting a classification of ASD. Interpretation Patients with PTHS are characterized not only by specific physical and genetic manifestations but also by specific behavioural and cognitive characteristics. Studying behaviour and cognition may improve diagnosis and prognosis, allows recognition of comorbidities, and contributes to adequate counselling of families. © The Authors.

Objective: Several meta-analyses considering repetitive transcranial magnetic stimulation (rTMS) for auditory verbal hallucinations (AVH) have been performed with moderate to high mean weighted effect sizes. Since then several negative findings were reported in relatively large samples. The aim of this study was to provide an update of the literature on the efficacy of rTMS for AVH and to investigate the effect of rTMS one month after the end of treatment. Data sources: A literature search was performed from 1966 through August 2012 using Cochrane Central Register of Controlled Trials, Cochrane Database of Systematic Reviews, Database of Abstracts of Reviews of Effects, Embase Psychiatry, Ovid Medline, PsycINFO and PubMed. Randomized, double blind, sham-controlled studies with severity of AVH or severity of psychosis as an outcome measure were included. Study selection: Data were obtained from 17 randomized studies of rTMS for AVH. Five studies fulfilled the criteria for the meta-analysis on the effect of rTMS one month after the end of treatment. Data extraction: Standardized mean weighted effect sizes of rTMS versus sham were computed on pre- and posttreatment comparisons. Data synthesis: The mean weighted effect size of rTMS directed at the left temporoparietal area was 0.44 (95% CI 0.19-0.68). A separate meta-analysis including studies directing rTMS at other brain regions revealed a mean weighted effect size of 0.33 (95% CI 0.17-0.50) in favor of real TMS. The effect of rTMS was no longer significant at one month of follow-up (mean weighted effect size = 0.40, 95% CI - 0.23-0.102). Side effects were mild and the number of dropouts in the real TMS group was not significantly higher than in the sham group. Conclusions: With the inclusion of studies with larger patient samples, the mean weighted effect size of rTMS directed at the left temporoparietal area for AVH has decreased, although the effect is still significant. The duration of the effect of rTMS may be less than one month. More research is needed in order to optimize parameters and further evaluate the clinical relevance of this intervention. © 2012 Elsevier B.V.

Eating disorders are relatively rare among the general population. This review discusses the literature on the incidence, prevalence and mortality rates of eating disorders. We searched online Medline/Pubmed, Embase and PsycINFO databases for articles published in English using several keyterms relating to eating disorders and epidemiology. Anorexia nervosa is relatively common among young women. While the overall incidence rate remained stable over the past decades, there has been an increase in the high risk-group of 15-19 year old girls. It is unclear whether this reflects earlier detection of anorexia nervosa cases or an earlier age at onset. The occurrence of bulimia nervosa might have decreased since the early nineties of the last century. All eating disorders have an elevated mortality risk; anorexia nervosa the most striking. Compared with the other eating disorders, binge eating disorder is more common among males and older individuals. © The Author(s) 2012.

Despite a growing interest in auditory verbal hallucinations (AVHs) in different clinical and nonclinical groups, the phenomenological characteristics of such experiences have not yet been reviewed and contrasted, limiting our understanding of these phenomena on multiple empirical, theoretical, and clinical levels. We look at some of the most prominent descriptive features of AVHs in schizophrenia (SZ). These are then examined in clinical conditions including substance abuse, Parkinson's disease, epilepsy, dementia, late-onset SZ, mood disorders, borderline personality disorder, hearing impairment, and dissociative disorders. The phenomenological changes linked to AVHs in prepsychotic stages are also outlined, together with a review of AVHs in healthy persons. A discussion of key issues and future research directions concludes the review. © 2012 The Author.

CNS Drugs | Year: 2012

Ghrelin is the only known circulating orexigenic hormone. It increases food intake by interacting with hypothalamic and brainstem circuits involved in energy balance, as well as reward-related brain areas. A heightened gut-brain ghrelin axis is an emerging feature of certain eating disorders such as anorexia nervosa and Prader-Willi syndrome. In common obesity, ghrelin levels are lowered, whereas post-meal ghrelin levels remain higher than in lean individuals. Agents that interfere with ghrelin signalling have therapeutic potential for eating disorders, including obesity. However, most of these drugs are only in the preclinical phase of development. Data obtained so far suggest that ghrelin agonists may have potential in the treatment of anorexia nervosa, while ghrelin antagonists seem promising for other eating disorders such as obesity and Prader-Willi syndrome. However, large clinical trials are needed to evaluate the efficacy and safety of these drugs. © 2012 Adis Data Information BV. All rights reserved.

Objective: Body dysmorphic disorder (BDD), an abnormal preoccupation with perceived defects in one or more body parts, and eating disorders (ED) share several essential clinical features, making it sometimes difficult to differentiate between the two disorders. The aims of this study were to assess the prevalence of BDD in patients with ED and to compare characteristics of ED patients with and without BDD. Method: We measured dysmorphic appearance concerns and behaviors, ED symptoms, general psychopathology, and quality of life in 158 patients seeking treatment for ED. Results: Forty-five percent screened positive for BDD. Patients with both disorders (ED + BDD) had significantly more dysmorphic appearance concerns, had more psychopathology, and were dissatisfied with a larger number of body parts than patients with ED only. The differences remained significant even after correcting for severity of eating disorder psychopathology. Discussion: This finding suggests that BDD is a distinct comorbid disorder in almost half of the patients with ED. It is thus important to recognize and treat the manifestation of BDD in patients with both disorders. Given that the treatment of BDD is different from that of ED, it is important to recognize BDD. © 2012 Wiley Periodicals, Inc.

Background: Anxiety and challenging behaviour (CB) often occur simultaneously in people with intellectual disabilities (ID). Understanding the associations between anxiety and CB may contribute to more accurate diagnoses and management of both anxiety and CB in this population. Aims: To examine the relationship between anxiety and CB. Methods: A literature review covering the period from January 2000 to January 2012. Results: Seven studies about the relationship between psychiatric disorders, including anxiety, and CB were identified. These studies confirm the relationship between anxiety and CB in people with ID, although the precise nature of this relationship remains unclear. Conclusions: The study points toward the existence of a moderate association between anxiety and CB. Further research is needed to clarify the complex nature of the association between anxiety and CB. © 2013 John Wiley & Sons Ltd, MENCAP & IASSIDD.
