Filter by:The purpose of this study is to determine whether estrogen may help reduce fear of high calorie-density foods in weight-restored women with Anorexia Nervosa (AN).
The primary objective of this study is to gain knowledge about the effectiveness of enhanced cognitive behavioral therapy (CBT-E) for anorexia nervosa (AN).
Anorexia nervosa is an eating disorder characterized by intense fear of becoming fat despite the obvious thinness and extreme behaviors for weight loss. The result is a massive weight loss and / or pathological thinness. The care of anorexia is difficult and few treatments have proved to be effective in adults. Transcranial direct current stimulation (tDCS) is a neuromodulation technique that uses an electrical current of low intensity. It allows to modulate the corticospinal excitability: two electrodes, an anode (excitatory) and a cathode (inhibitory), are positioned on the skull according to the region which is desired to influence the operation. Although tDCS was shown to no noticeable side effects, it is first necessary to assess the feasibility and safety of this technique in these physically frail patients. A recent pilot study suggests the acceptability, safety and efficacy of tDCS program in patients with anorexia nervosa. Given these preliminary data and the extreme seriousness and vulnerability of patients with resistant anorexia, the investigators want to assess the risk / benefit ratio for the use of this technique in patients suffering from resistant anorexia nervosa. The current data are too preliminary to consider a randomized controlled trial, the investigators hope, initially, replicate the data from this pilot study in a second sample with a more rigorous and comprehensive assessment methodology .
This trial will compare the efficacy and tolerability of 10 Hz vs. 1 Hz vs. sham repetitive transcranial magnetic stimulation targeting the dorsomedial prefrontal cortex, delivered once daily over 30 days, in patients with a diagnosis of bulimia or anorexia nervosa binge-purge subtype. The trial will include structural and functional MRI, and behavioral measures obtained before, during, and after treatment.
A reliably effective treatment model for anorexia nervosa is yet to emerge. Recent clinical trials of psychological therapies over 20-30 sessions, have shown modest benefits. There is therefore a need to test new treatments to find more effective treatments. Clinical trials of Schema Therapy have shown low rates of dropout, which is often a problem in the treatment of anorexia nervosa. Treatment with Schema Therapy, for significantly longer than 20-30 sessions, has been shown to be effective for other complex mental health problems.This pilot study is therefore designed to pilot the use of individual Schema Therapy for people with Anorexia Nervosa (iST-AN). This study is a case series pilot study. The study will answer the principal research question: Does individual Schema mode Therapy, adapted for eating disorders, have the potential to improve symptoms, quality of life and weight in people with moderate-severe anorexia nervosa? It will also address secondary research questions: Can people with moderate-severe anorexia nervosa be recruited to, and kept engaged in, a study of iST-AN treatment? What is the ideal length of iST-AN treatment? What is the relationship between self-criticism, body shame, or unhelpful psychological 'modes' and clinical outcome? Fifteen people with moderate-severe Anorexia Nervosa will be recruited from referrals to a specialist eating disorders outpatient service. The study will deliver 65 sessions of Schema Therapy for anorexia nervosa (iST-AN), over a 24 month period, alongside any additional medical or dietetic management required. Standard outcome measures will be collected at 6 month intervals. The research team have expertise in eating disorders research, schema therapy for severe anorexia nervosa and are all members of the local clinical service. The study will take place over a 3 year period.
The purpose of this multi-center randomized controlled trial is to compare lower calorie refeeding to higher calorie refeeding for hospitalized adolescents and young adults with AN. The investigators will compare efficacy (achievement and maintenance of clinical remission at 12 months), safety during hospitalization, and cost effectiveness (including costs of initial and re hospitalization, 12 month follow up and safety/adverse events).
This study aims to identify the brain regions responsible for encoding cardiorespiratory 'interoceptive' sensations and determine whether they are dysfunctional in individuals affected by eating disorders, anxiety, depression, or brain injury. By evaluating the same interoceptive sensations across different human illnesses, the investigators hope to provide convergent evidence resulting in identification of core underlying neural processes, and to discern relative contributions in each condition.
The role of impulsivity and its contribution to suicidal behavior seems intuitively clear. Empirical results have proved the existence of a relationship between the two yet many questions are left unanswered, especially what differentiates suicide ideators from attempters.. Obsessive thinking patterns are thought processes which share a repetitive behavior domain and are exerted by an inner voice. 3 types of obsessive thinking patterns are self destructive thoughts, ruminations and overvalued ideas. Impulsivity and obsessive thinking patterns are presumed to have a common mechanism of behaviors which are resulted from basal ganglia dysregulation and thus effect inhibition. Novel research in the field of decision making could help to learn more about behavioral patterns associated with self harm behavior and suicide. Eating Disorders involve suicidal and self harm behavior, which both feature impulsivity and obsessive thinking patterns. The investigators study proposes a 3-step theoretical model which asserts there is a connection between impulsivity, obsessive thinking and poor decision making, all effecting self harm behavior. Contemporary research has not been able to fully understand the nature of impulsivity and its effect on self harm behavior, including eating disorders symptoms, nor addressed the impact of obsessive thinking patterns on the latter. 100 female participants with Eating Disorders and suicidal behavior will be recruited for the proposed research. Subjects will be given self-report questionnaires and computerized behavioral tasks. A one way ANOVA of two eating disorder subgroups, impulsive and non impulsive, will be conducted, following a hierarchical multiple regression with self harm behavior being the dependent variable.
Anorexia nervosa (AN) is a complex and severe psychiatric disorder with high relapse rates under standard treatment.Deep brain stimulation (DBS) may be a novel treatment in severe Anorexia nervosa.
There are two major goals of this investigation. First, to develop pilot data to justify a larger randomized clinical trial of an intervention designed to train interoceptive signals (IS) and interoceptive responsivity (IR) in persons with Anorexia Nervosa (AN). Second, the investigators will determine whether persons with AN have similar or different IS and IR for heart rate while exercising as compared to age and gender matched controls.
