Heart Rate Sensing and Response in Persons With Anorexia Nervosa

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.

Therapeutic Drug Monitoring in Child and Adolescent Psychiatry

DepressionAnorexia Nervosa1 more

The investigators aim to analyse in adolescents with mental illness effectiveness, side effects, and serum level concentrations of antipsychotics (olanzapine and aripiprazole), antidepressants (Duloxetine, Atomoxetine) by means of "Therapeutic Drug Monitoring" (TDM) in order to optimize dosage - effect relations and minimize unwanted side effects.

Functional Magnetic Resonance Imaging (fMRI) Imaging Study in Adolescents With Anorexia Nervosa...

Anorexia Nervosa

The purpose of this study is to use fMRI imaging technology to examine areas in the brain related to appetite, reward and cognition in adolescent women with eating disorders as compared to those who have never had an eating disorder. Better understanding biologic vulnerabilities in women with anorexia is essential for developing more effective treatment options.

Inhibitory Control and Eating Disorders

Anorexia NervosaBulimia Nervosa1 more

Executive functions are part of the high-level cognitive processes essential to the proper functioning of human cognition. They consist mainly of flexibility, updating and inhibition. Some studies have shown a correlation between executive disorders (impaired executive function) and psychiatric disorders such as obsessive-compulsive disorder or phobias. These executive disorders are related to dysfunctions of the fronto-striatal loops. In addition, other studies have investigated the link that may exist between eating disorders such as anorexia or bulimia nervosa and executive functioning. Anorexia nervosa, bulimia nervosa and binge eating disorders are eating disorders characterized by a dysfunction in food intake with restriction of food or compulsions as well as strong concerns about the body schema. Concerning the executive functioning, these studies highlight a lack of cognitive flexibility for patients with anorexia nervosa and bulimia nervosa but also dysfunctions depending on the type of pathology (anorexia nervosa or bulimia nervosa). These studies also highlight the beneficial effects of cognitive remediation on people with eating disorders. However, the investigation of the inhibitory control has not yet been specifically studied. Moreover, since eating disorders are structurally different, a comparison between several pathologies would be interesting to consider. The aim of this study is to determine if a dysfunction of inhibitory control can be highlighted in people with eating disorders. This study would also allow further researches about cognitive remediation suitable for the specific difficulties encountered in these diseases.

The Impact of Oxytocin on the Neurobiology of Anorexia Nervosa

Anorexia Nervosa

This study will use a randomized, controlled, double-blind design involving the administration of intranasal oxytocin (INOT) or placebo to adults with anorexia nervosa, restricting subtype and age-matched controls prior to neuroimaging to assess the impact on frontolimbic brain activity in response to socioemotional stimuli as well as eating behavior in a test meal paradigm.

Geriatric Anorexia Study

Healthy

Reduction in appetite and/or food intake among older individuals is referred to as anorexia of aging (AOA, also known as Geriatric Anorexia). AOA is linked with myriad comorbidities associated with aging, contributes significantly to adverse health consequences in old age, and has been used as a predictor of morbidity and mortality. The overall aim of this study is to assess the feasibility and burden of the proposed in-laboratory and out-of-laboratory assessments to study Geriatric Anorexia. This will be accomplished with the use of questionnaires as well as devices that evaluate movement, metabolism, body weight composition, glucose levels, and nutritional scale.

Correlation Study Between Heart Rate Variability and Anxiety in Anorexia Nervosa

Anorexia Nervosa

The heart rate variability (HRV) is a measure of the autonomic nervous system (ANS). In the model of anorexia nervosa, ANS is disturbed with mostly a predominance of activation of the parasympathetic nervous system and a decrease of the sympathetic system. Various explanations of this these dysfunctions are proposed in literature, mainly malnutrition, physical hyperactivity, anxiety, that are known characteristics of anorexia nervosa. The primary aim of this study is to evaluate correlation between ANS dysfunction and anxiety in anorexia nervosa. Other objectives of this study are firstly to evaluate correlation between ANS dysfunction and others parameters (weight, body mass index, depression, physical activity, purgative ou restrictive type, duration of disease, smoking) in anorexia nervosa and secondly to see if HRV is a predictive parameter of the evolution of anorexia nervosa.

Representations and Strategies for Recovery

SchizophreniaUndifferentiated3 more

In the recent context of deinstitutionalization and longitudinal studies pointing to a large number of positive long-term outcommes for people affected by a psychiatric disorder (schizophrenia, bipolar disorder, eating disorder, severe personality disorder, etc.), the possibility of overcoming the consequences of a psychiatric pathology emerges as a solid fact. Therefore, the existence of this possibility calls for the identification of the determinants underlying of the various outcomes over time of those affected by a severe psychiatric disorder, in particular those likely to underpin the most positive developments. While it is well known from a medical point of view that certain dimensions affect the prognosis of persons affected by a severe psychiatric disorder (such as the persistence of negative symptoms or cognitive disorders in schizophrenic disorders), prognosis from a purely medical perspective (and putting aside the role of the person and his environment) seems to be able to account only for a modest proportion of the prognosis of people affected by a serious psychiatric disorder. It is this fact that has gradually led to the emergence of complementary models capable of enriching the understanding of the determinants of the future of people affected by a severe psychiatric disorder, in particular models inviting to separate "becoming of the person" from the " psychiatric disorder "to take into account the" personal role of the person "in his or her own healing. This perspective is the "recovery" perspective. Recovery process is defined as a personal trajectory which includes the person's experiences and the reactions of his / her environment following the installation of a psychiatric disorder, which can support a mode of release of the status of "psychiatric patient". Recovery thus implies an "approach underpinned by the understanding of the human response to pathology" (Noiseux) and, one might add, of its environment. However, while these studies point to a number of crucial dimensions involved in the recovery of a severe psychiatric disorder, one of the important limitations of these studies is the distance from any psychopathological consideration, thus setting aside the possibility of specific processes of recovery depending of the pathology. The identification of recurrent experiential logics specific to the various psychiatric disorders therefore appears to be an important field of investigation. It would potentially be able to guide the development of new therapeutic devices based on the recovery model.
