Anorexia nervosa

"Health care professionals should use clinical judgment regarding fluoxetine or possibly citalopram, sertraline or mirtazapine as adjunctive treatment to psychotherapy for relapse prevention, improvement of depressive and anxiety symptoms, and/or obsessive-compulsive behaviors unresolved with nutritional rehabilitation and psychotherapy."

"Etiological theories emphasize interpersonal and family dysfunction in the development of anorexia nervosa. Research supports the notion that families of individuals with anorexia nervosa have dysfunctional patterns of communication. The history of treatment for anorexia nervosa emphasizes the need for resolution of interpersonal dysfunction, within the traditions of psychodynamic, family therapy, and multidimensional therapies."

"Interpersonal psychotherapy is a time-limited psychotherapy based on the notion that regardless of etiology, interpersonal relationships are intertwined with symptomatology. The goals of the therapy are to improve interpersonal functioning and thereby decrease symptomatology. Factors identified as important in the development of anorexia nervosa are readily conceptualized within the interpersonal psychotherapy problem areas of grief, interpersonal disputes, interpersonal deficits, and role transitions."

"In recent years, anorexia and bulimia nervosa, whether combined into a single clinical picture or considered as distinct syndromes, have reached epidemic proportions among adolescents. Professionals in the educational and physical and mental health care fields need to be aware of the influence of social pressures on teenagers' perceptions of body image and appearance. This article reviews the sociocultural, socioeconomic, and sex-related factors which contribute to the development of eating disorders. It is recommended that professionals help adolescents resist societal pressure to conform to unrealistic standards of appearance, and provide guidance on nutrition, realistic body ideals, and achievement of self-esteem, self-efficacy, interpersonal relations and coping skills."

"Purging can include self-induced vomiting, over-exercising, and the use of diuretics, enemas, and laxatives. Anorexia nervosa is characterized by extreme food restriction and excessive weight loss, accompanied by the fear of being fat."

"Prior research on non-clinical samples has lent support to the sexual competition hypothesis for eating disorders (SCH) where the drive for thinness can be seen as an originally adaptive strategy for women to preserve a nubile female shape, which, when driven to an extreme, may cause eating disorders. Restrictive versus impulsive eating behavior may also be relevant for individual differences in allocation of resources to either mating effort or somatic growth, reflected in an evolutionary concept called "Life History Theory" (LHT). In this study, we aimed to test the SCH and predictions from LHT in female patients with clinically manifest eating disorders. Accordingly, 20 women diagnosed with anorexia nervosa (AN), 20 with bulimia nervosa (BN), and 29 age-matched controls completed a package of questionnaires comprising measures for behavioral features and attitudes related to eating behavior, intrasexual competition, life history strategy, executive functioning and mating effort. In line with predictions, we found that relatively faster life history strategies were associated with poorer executive functioning, lower perceived own mate value, greater intrasexual competition for mates but not for status, and, in part, with greater disordered eating behavior. Comparisons between AN and BN revealed that individuals with BN tended to pursue a "fast" life history strategy, whereas people with AN were more similar to controls in pursuing a "slow" life history strategy. Moreover, intrasexual competition for mates was significantly predicted by the severity of disordered eating behavior. Together, our findings lend partial support to the SCH for eating disorders. We discuss the implications and limitations of our study findings."

"Annorexia can cause menstruation to stop, and often leads to bone loss, loss of skin integrity, etc. It greatly stresses the heart, increasing the risk of heart attacks and related heart problems. The risk of death is greatly increased in individuals with this disease."

"The speculation about whether there may be a positive association between sexual abuse in childhood and the later development of clinical eating disorder has been widely considered over the past 15 years. It has sometimes been accepted uncritically as established truth. It is certainly plausible. After all, bulimia and anorexia nervosa differentially affect girls and seem to involve complex feelings about the body which might well have originated in adverse early sexual experience. Furthermore, many patients disclose such experiences in the clinic. The evidence from early research studies, however, does not consistently support all of the clinical speculation. More than one review reached broadly negative conclusions.1,2 The study by Wonderlich et al systematically re-examines publications up to the end of 1994. The authors of this review had to grapple with studies employing a wide variety of methods and samples. They used predetermined criteria of quality but not meta-analysis to sort out which studies could contribute to their conclusions. They were appropriately strict in applying their criteria. This review supports the position of clinicians who consider that a history of childhood sexual abuse is worth seeking and may be an important consideration in their patients with eating disorders, but no more important than in many other patients. It may be especially relevant for those who have bulimia nervosa with comorbidity. Patients with such complex problems require careful thought. Finding a background of sexual abuse may prove to be important but should not lead to the conclusion that “all is now explained”. Furthermore, most studies show that only a minority of patients with eating disorders report abuse and inferring past abuse from the fact of present eating disorder is unjustified."

"There is good evidence that children of parents with psychological disorders are themselves at increased risk of disturbances in their development. Although there has been considerable research on a variety of disorders such as depression and alcohol, research on the children of parents with eating disorders has been relatively recent. This paper aims to review the evidence and covers a number of areas, including genetic factors, pregnancy, the perinatal and postpartum period, infancy, and the early years of life, focusing on feeding and mealtimes, general parenting functions, and growth. This is followed by a consideration of psychopathology in the children, parental attitudes to children's weight and shape, and adolescence. What is clear is that although there are numerous case reports and case series, the number of systematic controlled studies is relatively small, and almost nothing has been written about the children of fathers with eating disorders. What is evident from the available evidence is that children of mothers with eating disorders are at increased risk of disturbance, but that the risk depends on a variety of factors, and that difficulties in the children are far from invariable. The paper concludes by summarizing five broad categories of putative mechanisms, based on the evidence to date, by which eating disturbance in parents can influence child development."

"This study explored friendship variables in relation to body image, dietary restraint, extreme weight-loss behaviors (EWEBs), and binge eating in adolescent girls. From 523 girls, 79 friendship cliques were identified using social network analysis. Participants completed questionnaires that assessed body image concerns, eating, friendship relations, and psychological family, and media variables. Similarity was greater for within than for between friendship cliques for body image concerns, dietary restraint, and EWLBs, but not for binge eating. Cliques high in body image concerns and dieting manifested these concerns in ways consistent with a high weight/shape-preoccupied subculture. Friendship attitudes contributed significantly to the prediction of individual body image concern and eating behaviors. Use of EWLBs by friends predicted an individual's own level of use."

"In the literature, no review concerning the family comorbidity of mood and anxiety disorders of anorexic subjects exists. However, this data can be important for the comprehension of this disorder and for the assumption of responsibility."

"The group receiving nutritional counseling relapsed significantly earlier and at a higher rate than the group receiving cognitive behavior therapy (53% versus 22%). The overall treatment failure rate (relapse and dropping out combined) was significantly lower for cognitive behavior therapy (22%) than for nutritional counseling (73%). The criteria for "good outcome" were met by significantly more of the patients receiving cognitive behavior therapy (44%) than nutritional counseling (7%)."

"Cognitive behavior therapy was significantly more effective than nutritional counseling in improving outcome and preventing relapse. To the authors' knowledge, these data provide the first empirical documentation of the efficacy of any psychotherapy, and cognitive behavior therapy in particular, in posthospitalization care and relapse prevention of adult anorexia nervosa."

"The purpose of this study was to assess the relative contribution of personality and emotional experience to self-reported eating attitudes in a group of patients with clinically diagnosed eating disorders, a weight-reduction training group (Weight Watchers), and a control group without body weight problems. Participants in this study (N = 114) completed Estonian versions of the Eating Disorder Inventory-2 (EDI-2; Garner, 1991), NEO Personality Inventory (Costa & McCrae, 1989), and Positive Affect and Negative Affect Schedule, Expanded Form (Watson & Clark, 1994). Data demonstrated validity of the Estonian version of EDI-2 in its ability to identify problems on a continuum of disordered eating behavior. Among the Big Five personality dimensions, Neuroticism made the largest contribution to EDI-2 subscales. Two other dimensions, Openness to Experience and Conscientiousness, also predispose individuals to eating problems. Personality traits made a larger contribution to the self-reported eating pathology than the self-rated effects experienced during the last few weeks. It was argued that personality dispositions have a larger relevancy in the etiology of eating disorders than emotional state."

"Some contributory factors appear to be necessary for the appearance of eating disorders, but none is sufficient. Eating disorders may represent a way of coping with problems of identity and personal control."

"Suicide in anorexia nervosa and bulimia nervosa is a major cause of death. Risk factors for suicide and attempted suicide (which in many cases results in successful suicide) in anorexia nervosa include: purging type, chronic disease, and during treatment, obsessive symptoms and drug abuse, major depression, and for anorexia nervosa low body mass index (BMI) at presentation. In anorexia nervosa suicide has been considered the first cause of death and attempted suicide is a serious threat to these individuals. Data concerning suicide in bulimia nervosa has still scarce whereas attempted suicides are easily found in clinical histories of patients. No doubt suicidal behavior is underestimated amongst patients with anorexia nervosa and bulimia nervosa. An effort to reconcile with subject of suicide and a better evaluation of these patients' psychopathology should improve suicide prevention strategies amongst these individuals."

"Although it remains unclear whether the prevalence of eating disorders is higher in those with DRCHCs compared with the general population, overall findings suggest that young people with DRCHCs may be at risk of endorsing disordered eating behaviors that may lead to diagnosis of an eating disorder and other health problems over the course of their treatment. Thus, health care providers should be aware that young people with DRCHCs may be at risk of eating disorders and carefully monitor psychological changes and the use of unhealthy weight control methods. It is also important to develop and evaluate theory-based interventions and disease-specific eating disorder risk screening tools that are effective in halting the progression of eating disorders and negative health outcomes in young people with chronic health conditions."

"The development of eating disorders including anorexia nervosa, bulimia nervosa, binge eating disorder, and atypical eating disorders that affect many young women and even men in the productive period of their lives is complex and varied. While numbers of presumed risk factors contributing to the development of eating disorders are increasing, previous evidence for biological, psychological, developmental, and sociocultural effects on the development of eating disorders have not been conclusive. Despite the fact that a huge body of research has carefully examined the possible risk factors associated with the eating disorders, they have failed not only to uncover the exact etiology of eating disorders, but also to understand the interaction between different causes of eating disorders. This failure may be due complexities of eating disorders, limitations of the studies or combination of two factors. In this review, some risk factors including biological, psychological, developmental, and sociocultural are discussed."

"It has been hypothesized that eating disorders have multiple and often shared etiologies including biological, psychological, developmental, and sociocultural. A tightly woven network of causes, symptoms, and outcomes of eating disorders makes the study of etiology of these disorders very challenging. Some suggested risk factors for eating disorders require to be defined as either integral parts of eating disorders syndrome such as body dissatisfaction, and perfectionism or outcome of prolonged disordered eating such as functional alterations in serotonin, and some mood disturbances. Researchers should structure their thought processes around this concept that some of currently well-known risk factors for eating disorders are concurrent symptoms of eating disorders. Hence paying special attention to the new and evolved concepts is highly recommended while studying the etiology of eating disorders."

"This article describes the qualitative analysis of a randomized control trial that explores the use of parent-to-parent consultations as an augmentation to the Maudsley model of family-based treatment for anorexia. Twenty families were randomized into two groups, 10 receiving standard treatment and 10 receiving an additional parent-to-parent consultation. Parents of all families were interviewed regarding their experience of treatment and transcripts were analyzed with the assistance of QSR N-Vivo. Parents described parent-to-parent consultations as an intense emotional experience that helped them to feel less alone, to feel empowered to progress, and to reflect on changes in family interactions. These results suggest that parent-to-parent consultations are seen as a useful augmentation to the Maudsley model of family-based treatment for anorexia nervosa."

"Tumours of the central nervous system mostly present with neurological symptoms and signs of intracranial hypertension. Several reports of cerebral tumors in adolescents outline initial symptoms of anorexia and emaciation, leading to the diagnosis of anorexia nervosa."

"We report on a 15.5-year-old girl with a craniopharyngioma. The girl had a 2 year history of weight loss, dystrophy, no onset of puberty, and a 6 year history of headache. These symptoms had led initially to the clinical diagnoses of migraine and anorexia nervosa, since unenhanced computed tomography of the brain was normal. At presentation, physical examination showed short stature (height SDS - 3.6) and Tanner stage I. Bone age delay was about four years. Laboratory analyses showed hypopituitarism. The diagnosis of craniopharyngioma was made by repeated imaging, depicting an intrasellar and parasellar mass, which was totally removed by neurosurgery. Hormonal substitution with hGH, L-thyroxine, hydrocortisone, and estrogens led to normal physiological development and final height within upper target height."

"The reported case illustrates that the diagnosis of craniopharyngioma is often delayed due to unspecific clinical symptoms. Careful evaluation of anthropometrics, ophthalmologic, and endocrine data in patients with suspected eating disorders may give additional clues to the diagnosis of a craniopharyngioma."

"Studies have reported that the oral health status is jeopardized in patients with eating disorders. The aim was to review the oro-facial manifestations in patients with eating disorders. The address the focused question was "What is the oro-dental health status in patients with eating disorders?" MEDLINE/PubMed and Google Scholar databases were searched from 1948 to March 2012 using the following terms in various combinations: "Anorexia nervosa", "bulimia nervosa", "eating disorders", "dental", "oral health status". Letters to the editor, unpublished data and articles published in languages other than English were excluded. Dry lips, burning tongue and parotid gland swelling are common manifestations in patients with eating disorders as compared to medically healthy controls. The association of dental caries and periodontal disease in patients with eating disorders remains debatable. Temporomandibular disorders have also been reported to be more prevalent in patients with eating disorders as compared to healthy controls. A critical oral-dental examination during routine dental check-ups may reveal valuable information regarding the presence or absence of eating disorders in routine dental patients. This may be important information, updating the medical history, supporting the role of the physician."

"Comorbid personality disorders in eating disordered patients may seriously affect the treatment and course of their illness. Several studies show such a comorbidity, though with inconsistent findings. Qualitative reviews attribute this to methodological shortcomings, but the qualitative method may itself create new shortcomings. To circumvent this, the present, more extensive review applies a meta-analytic approach. Using the databases MEDLINE and PSYCHLIT, the 28 articles published between 1983 and 1998 that presented empirical evidence for an eating disorder and personality disorder comorbidity suitable for meta-analysis were included. We found a higher proportion of eating disordered patients with any personality disorder (average proportion = 0.58) related to comparison groups (average proportion = 0.28). Compared with anorexia nervosa patients, a higher proportion of patients with bulimia nervosa had a concurrent cluster B personality (average proportion = 0.44) and a borderline personality disorder (average proportion = 0.31). However, no differences between anorexia nervosa and bulimia nervosa patients in proportions of cluster C were found (average proportion = 0.45 and 0.44 respectively). Patients with eating disorders and patients with bulimia nervosa in particular, should be routinely assessed for a concurrent personality disorder using structured clinical interviews. In future research, more stringent assessment procedures are highly recommended to address the question of causality between eating disorders and personality disorders, and how eating disorder symptoms and personality disorder symptoms are related to treatment effects."

"The aim of this investigation was to study the relationship between unhealthy eating habits and behaviors, perception and acceptance of societal standards regarding thinness, body dissatisfaction, and family and peer pressure to be thin. One hundred and twentythree high school girls from Rijeka (Croatia) were surveyed using Eating Attitudes Test (EAT- 26), Sociocultural Attitudes Towards Appearance Questionnaire (SATAQ), Body Esteem Questionnaire for Adolescents and Adults (BES), and Scale of perceived pressure to be thin from family and peers. The results of path analyses showed that social pressure from family and peers, experience of weight-related teasing and criticism by family members, contributed to development of eating disturbance. The acceptance of social standards related to appearance, contributed to onset of disturbed eating habits. Weight satisfaction alone influences the development of some eating disorder symptoms, but it is also a mediator of higher body mass index (BMI) and internalization of societal appearance standards. Girls with higher BMI, who accepted societal standards of thin-ideal, perceived major social pressure to be thin through direct and persuasive comments designed to establish the importance of dieting, and probably develop eating disturbed habits, or some symptoms of anorexia (AN) or bulimia nervosa (BN)."

"Anorexia nervosa (AN) is a severe and often chronic disorder with uncertain aetiology and poor prognosis. New approaches to the understanding of the disorder are needed in order to aid the development of more effective treatments. Several authors have suggested that AN has a considerable overlap with obsessive-compulsive disorder (OCD) and that this may reflect common neurobiological, genetic, or psychological elements. However, more recent studies have suggested that AN may have a closer relationship with obsessive-compulsive personality traits such as those found in obsessive-compulsive personality disorder (OCPD). In this paper, evidence for links between the three conditions is reviewed, suggestions for further research are outlined and possible implications for the treatment of AN are presented."

"The cognitive model of eating disorders (EDs) states that the processing of external and internal stimuli might be biased in mental disorders. These biases, or cognitive errors, systematically distort the individual's experiences and, in that way, maintains the eating disorder. This chapter presents an updated literature review of experimental studies investigating these cognitive biases. Results indicate that ED patients show biases in attention, interpretation, and memory when it comes to the processing of food-, weight-, and body shape-related cues. Some recent studies show that they also demonstrate errors in general cognitive abilities such as set shifting, central coherence, and decision making. A future challenge is whether cognitive biases and processes can be manipulated. Few preliminary studies suggest that an attention retraining and training in the cognitive modulation of food reward processing might be effective strategies to change body satisfaction, food cravings, and eating behavior."

"An individual who is a first degree relative of someone who has had or currently has an eating disorder is seven to twelve times more likely to have an eating disorder themselves. Twin studies also show that at least a portion of the vulnerability to develop eating disorders can be inherited, and there is evidence to show that there is a genetic locus that shows susceptibility for developing anorexia nervosa."

"Anorexia nervosa is currently considered a disorder confined to Western culture. Its recent identification in non-Western societies and different subcultures within the Western world has provoked a theory that Western cultural ideals of slimness and beauty have infiltrated these societies. The biomedical definition of anorexia nervosa emphasizes fat-phobia in the presentation of anorexia nervosa. However, evidence exists that suggests anorexia nevosa can exist without the Western fear of fatness and that this culturally biased view of anorexia nervosa may obscure health care professionals' understanding of a patient's own cultural reasons for self-starvation, and even hinder their recovery."

"Patients with eating disorders (ED) frequently exhibit additional psychiatric disorders. This study aimed to examine whether psychiatric comorbidity in ED patients is associated with increased severity of ED symptoms in a sample of 277 women with a current ED (84 anorexia nervosa, 152 bulimia nervosa, 41 eating disorders not otherwise specified). Psychiatric comorbidity of Axes I and II was determined using the Structured Clinical Interview (SCID) for DSM-IV. Severity of ED-related symptoms was assessed using interviewer-rated scales from the Structured Interview for Anorexia and Bulimia Nervosa (SIAB). Affective and anxiety-related disorders of both axes were linked with increased intensity of weight- and appearance-related fears and concerns. Frequency of binge-eating and frequency of purging both were associated with Axis I anxiety disorders, substance-related disorders, and Cluster B personality disorders. Frequency of dieting was related to anxiety disorders on both axes. Multivariate analyses revealed that Axis I anxiety disorders were more closely linked with severity of ED symptoms than affective or substance-related disorders. The results showed that psychiatric comorbidity of both axes is linked with increased severity of ED symptoms and that there are associations between specific ED symptoms and specific forms of comorbidity."

"Eating disorders, such as anorexia, bulimia, and binge eating disorder, commonly involve a dysregulation of behavior (e.g., a lack or excess of inhibition and impulsive eating patterns) that is suggestive of prefrontal dysfunction. Functional neuro-imaging studies show that prefrontal-subcortical systems play a role in eating behavior and appetite in healthy individuals, and that people with eating disorders have altered activity in these systems. Eating behavior is often disturbed by illnesses and injuries that impinge upon prefrontal-subcortical systems. This study examined relationships between executive functioning and eating behavior in healthy individuals using validated behavioral rating scales (Frontal Systems Behavior Scale and Eating Inventory). Correlations demonstrated that increased dysexecutive traits were associated with disinhibited eating and greater food cravings. There was also a positive association with cognitive restraint of eating, suggesting that increased compensatory behaviors follow disinhibited eating. These psychometric findings reinforce those of other methodologies, supporting a role for prefrontal systems in eating."

"Recent research has modified both the conceptualization and treatment of eating disorders. New diagnostic criteria reducing the "not otherwise specified" category should facilitate the early recognition and treatment of anorexia nervosa (AN) and bulimia nervosa (BN). Technology-based studies identify AN and BN as "brain circuit" disorders; epidemiologic studies reveal that the narrow racial, ethnic and income profile of individuals no longer holds true for AN. The major organs affected long term-the brain and skeletal system-both respond to improved nutrition, with maintenance of body weight the best predictor of recovery. Twin studies have revealed gene x environment interactions, including both the external (social) and internal (pubertal) environments of boys and of girls. Family-based treatment has the best evidence base for effectiveness for younger patients. Medication plays a limited role in AN, but a major role in BN. Across diagnoses, the most important medicine is food."

"There were large variations in the outcome parameters across studies. Mortality estimated on the basis of both crude and standardized rates was significantly high. Among the surviving patients, less than one-half recovered on average, whereas one-third improved, and 20% remained chronically ill. The normalization of the core symptoms, involving weight, menstruation, and eating behaviors, was slightly better when each symptom was analyzed in isolation. The presence of other psychiatric disorders at follow-up was very common. Longer duration of follow-up and, less strongly, younger age at onset of illness were associated with better outcome. There was no convincing evidence that the outcome of anorexia nervosa improved over the second half of the last century. Several prognostic features were isolated, but there is conflicting evidence. Most clearly, vomiting, bulimia, and purgative abuse, chronicity of illness, and obsessive-compulsive personality symptoms are unfavorable prognostic features."

"Anorexia nervosa did not lose its relatively poor prognosis in the 20th century. Advances in etiology and treatment may improve the course of patients with anorexia nervosa in the future."

"Anorexia nervosa (AN) has the highest mortality rate between psychiatric disorders, and evidence for managing it is still very limited. So far, pharmacological treatment has focused on a narrow range of drugs and only a few controlled studies have been performed. Furthermore, the studies have been of short duration and included a limited number of subjects, often heterogenic with regard to stage and acute nutritive status. Thus, novel approaches are urgently needed. Body weight homeostasis is tightly regulated throughout life. With the discovery of orexigenic and anorectic signals, an array of new molecular targets to control eating behavior has emerged. This review focuses on recent advances in three important signal systems: leptin, ghrelin, and endocannabinoids toward the identification of potential therapeutical breakthroughs in AN. Our review of the current literature shows that leptin may have therapeutic potentials in promoting restoration of menstrual cycles in weight restored patients, reducing motor restlessness in severely hyperactive patients, and preventing osteoporosis in chronic patients. Ghrelin and endocannabinoids exert orexigenic effects which may facilitate nutritional restoration. Leptin and endocannabinoids may exert antidepressive and anxiolytic effects. Finally, monitoring serum concentration of leptin may be useful in order to prevent refeeding syndrome. Circulating concentrations of leptin are exceedingly low during the acute stage of anorexia nervosa. Which symptoms result from these diminished concentrations must be clarified. Furthermore, research is required to evaluate whether or not a too rapid weight gain might induce a physiological counter-regulation which would predispose to renewed loss of weight."

"Eating disorders are significant causes of morbidity and mortality in adolescent females and young women. They are associated with severe medical and psychological consequences, including death, osteoporosis, growth delay and developmental delay. Dermatologic symptoms are almost always detectable in patients with severe anorexia nervosa (AN) and bulimia nervosa (BN), and awareness of these may help in the early diagnosis of hidden AN or BN."

"Anorexia nervosa (AN) is a severe mental illness. Drug treatments are not effective and there is no established first choice psychological treatment for adults with AN. Neuropsychological studies have shown that patients with AN have difficulties in cognitive flexibility: these laboratory based findings have been used to develop a clinical intervention based on Cognitive Remediation Therapy (CRT) which aims to use cognitive exercises to strengthen thinking skills."

"This preliminary study suggests that CRT changed performance on flexibility tasks and may be beneficial for acute, treatment resistant patients with AN. Feedback gathered from this small case series has enabled modification of the intervention for a future larger study, for example, by linking exercises with real life behavioural tasks and including exercises that encourage global thinking."

"This exploratory study has produced encouraging data supporting the use of CRT in patients with AN: it has also provided insight into how the module should be tailored to maximise its effectiveness for people with acute AN."

"This review summarises the results of psychopharmacological treatment studies on anorexia and, bulimia nervosa. Although several drugs have tested in patients with anorexia nervosa, the outcome of controlled studies has been disappointing. Trials of pharmacotherapy for bulimia nervosa have demonstrated that tricyclic antidepressants, monoamine oxidase inhibitors and selective serotonin reuptake inhibitors significantly reduce the frequency of binge eating and purging. In some cases, psychotherapists should accept the necessity of psychopharmacological intervention, although this does not imply a known biological cause of the eating disorder. However, the significance of antidepressant medication in the overall treatment of anorexia and bulimia nervosa remains unclear."

"Studies using the Cloninger's personality theory suggested that high Harm Avoidance might be relevant to the pathology of anorexia nervosa and high Novelty Seeking and Harm Avoidance to bulimia nervosa."

"The Ben-Tovim Walker Body Attitudes Questionnaire (BAQ) is a psychometrically sound self-report instrument for assessing women's attitudes towards their own bodies. The BAQ responses of a large sample of patients with eating disorders (ED) diagnosed in accordance with DSM-III-R criteria were compared with those from a normative population and from diverse groups of psychiatrically and physically ill patients. The ED group was distinct, and showed extreme responses in the area of weight and shape concerns. But a better discrimination between the ED and other populations was achieved using subscales that related to 'body disparagement' (an intense loathing of the body) and 'attractiveness', rather than to weight and shape concerns. ED patients may have a more pervasive disturbance in body-related attitudes than is currently widely accepted. Patients with anorexia and bulimia nervosa showed very similar attitudes despite the symptomatic differences between the groups."

"There are a number of differences in the aetiology of subtypes of eating disorder. The present results suggest that cognitive styles pertaining to the social arena in adolescence, and prior to the onset of any eating disorders, may play a causal role in the development of anorexia nervosa of the binge/purge subtype, but not anorexia nervosa of the restricting subtype."

"Aetiology and pathogenesis of eating disorders is a matter of controversy. In some cases they can occur in association with tumours involving the temporal cortex, in temporal lobe epilepsy or in the advanced state of degenerative diseases involving temporal structures. We report about three patients with right frontal intracerebral lesions, one oligo-astrocytoma and two vascular malformations, associated with partial seizures and anorexia nervosa."

"Right frontal intracerebral lesions with their close relationship to the limbic system could be causative for eating disorders. We therefore recommend performing a cranial MRI in all patients with suspected eating disorders, especially if they occur in combination with focal seizures."

"Eating disorders, including anorexia and bulimia nervosa, are characterised by abnormal eating behaviour and typical psychopathological features, including fear of fatness, drive for thinness, and body image disturbance. In most patients, there is no detectable focal brain abnormality. Nonetheless, associations of anorexia and bulimia nervosa with history of perinatal complications and head injuries suggest a role of cerebral pathology in some cases. A number of case studies describe eating disorders with intracranial tumours, injuries, or epileptogenic foci. However, many clinical descriptions are limited to changes in appetite and lack psychopathological features characteristic of eating disorders. A previous review of 21 anorexia cases associated with brain tumours found that only three of them fulfilled formal diagnostic criteria. In the present paper, we provide a systematic review of published case reports and highlight those relatively rare cases where typical eating disorders appear to be causally associated with localised brain damage."

"Eighteen female inpatients were included in a double-blind placebo-controlled cross-over study aimed at testing the hypothesis that dopamine blockade may enhance the effectiveness of behavior therapy in the short-term weight restoration of anorexia nervosa patients. The patients were given a uniform contingency management program and, after a baseline period, they alternatingly (3-week periods) received pimozide (4 to 6 mg) or a placebo. During the first two periods pimozide almost significantly enhanced the weight gain induced by the behavior therapy program and beneficially influenced the patients' attitude towards treatment."

"Vandereycken, W; Pierloot, R (1982). combined with behavior therapy in the short-term treatment of anorexia nervosa. A double-blind placebo-controlled cross-over study". Acta Psychiatrica Scandinavica. 66 (6): 445–50. doi:10.1111/j.1600-0447.1982.tb04501.x. PMID 6758492."

"All dominant models of the eating disorders implicate personality variables in the emergence of weight concerns and the development of specific symptoms such as bingeing and purging. Standardized measures of personality traits and disorders generally confirm clinical descriptions of restricting anorexics as constricted, conforming, and obsessional individuals. A less consistent picture suggesting affective instability and impulsivity has emerged from the assessment of subjects with bulimia nervosa. Considerable heterogeneity exists within eating disorder subtypes, however, and a number of special problems complicate the interpretation of personality data in this population. These include young age at onset, the influence of state variables such as depression and starvation sequelae, denial and distortion in self-report, the instability of subtype diagnoses, and the persistence of residual problems following symptom control."
