Active clinical trials for "Bulimia"

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.

Adoption, twin and family studies have reported that obesity has a strong heritable component and in particular, it has been suggested that BMI in adults is due to genetic influence rather than shared family environment. Binge eating in obese patients was described. Therefore, it has been proposed that binge eating disorder (BED) may contribute to obesity in some individuals. Pharmacological studies reported that topiramate plays an important role in the treatment of binge eating disorder. It has been observed improvement of co-occurring binge eating disorder in patients receiving topiramate for treatment of mood disorders. In addition, topiramate was associated with anorexia and weight loss in clinical trials with epilepsy patients. Also, topiramate has been demonstrated efficacy in pilot and controlled studies for binge eating disorder (BED) associated with obesity. Genetic studies will be important to elucidate the mechanism by which putative susceptibility variation in candidate genes influences in pharmacological improvement of binge eating disorder in obese patients treated with topiramate. Connecting drug response with relevant functional DNA variants and differences in brain regions represents the ultimate goal for pharmacogenetic research playing an important role in advancing this understanding. The use of brain imaging combined with genetics can aid in understanding the pathophysiological mechanism of the disease. Additionally, brain imaging has the ability to bridge between preclinical research and human pharmacological studies. This will be a naturalistic clinical study designed to analyze the effect of genetic variants and neurofunctional brain areas associated with food craving in patients with obesity and binge eating disorder responders to topiramate. Hypothesis: The use of topiramate in obese subjects with binge eating disorder is associated with a differential gene variants and different activation brain areas in subjects that showed a reduction of food craving and weight lost.

The research proposed here seeks to delineate the outcomes of people who have received treatment for an eating disorder at a specialist eating disorder service in childhood or adolescence (hereafter 'former patients'). This will inform our understanding of the maintenance of treatment effects beyond initial trial follow-ups, and together with data collected during treatment will allow for identification of factors predicting chronicity which will inform further treatment development.

This study evaluated the periodontal status of patients suffering from eating disorders (anorexia nervosa and bulimia nervosa). The work hypothesis is that eating disorder patients have a higher risk for periodontal diseases than non-eating disorder subjects.
