Filter by:Anorexia nervosa (AN) is a common psychiatric illness, with severe prognosis (5% mortality) that has changed little over in half a century. One of the forms is the restrictive anorexia nervosa (ANR). It consists of a phobia of weight gain and food with a massive food restriction. This pathology is studied in psychology but not using the theories of embodied cognition in which "perception and action" interact through sensorimotor processes. They are the source of attitudes (unconscious) towards certain stimuli and influence our interpretation (conscious).
The primary aim of this study is to study how Repetitive Transcranial Magnetic Stimulation (rTMS) tailored to specific anorexia nervosa (AN) or bulimia nervosa (BN) brain activation alterations will promote recovery and to study how inhibitory tDCS (Transcranial Direct Current Stimulation) will reduce symptoms of body image distortion in a second sample of AN and BN groups.
The occurrence of anorexia nervosa (AN) during childhood or adolescence rapidly induces starvation, stop of growth and impaired mineralization of bone tissue together with an interruption of pubertal development. These consequences are initially reversible following food intake return but can lead to a more irreversible status with low height, osteoporosis and high fracture risk. The onset of the disease more and more early in life, with the first stages of puberty suggest that these consequences will be even more severe as bone resistance will be damaged by more profound effects on bone growth as well. It is therefore critical to evaluate these bone metabolism alterations in order to better manage these patients. At every age and in every clinical circumstance either physiologic or pathologic, high resolution peripheral quantitative computerized tomography (HRpQCT) provides an evaluation of bone microarchitecture that is more informative than the global quantitative assessment given by conventional Dual Energy X-ray Absorptiometry) DEXA, with a better estimate of clinical fracture risk. Here, we propose to measure cortical parameters, such as cortical thickness which plays a key role in bone biomechanical strength in young adults aged between 20 and 30 years-old, who had developed AN as early as the during the first stages of puberty but no longer present, compared to age-and sex-matched healthy volunteers. Other micro-architectural parameters will also be studied. In an exploratory phase, we will evaluate these bone microarchitectural parameters together with bone biological turnover markers and markers of sexual maturation in adolescents or young adults 20 years-old or less, undernourished and currently managed for AN.
The place of opioid system in anorexia nervosa (AN) physiopathology is still unclear. Conflicting results were published on cerebral spinal fluid or peripheral levels in anorexia nervosa. However, no data have been reported on opioid cerebral activity. Diprenorphine is a ligand with non-selective binding to opiate receptors µ, κ and δ capable to assess the interaction between endogenous opioids and their receptors.
In anorexia nervosa (AN) it still remains to be clarified, which psychiatric symptoms are the direct consequence of malnutrition and adaptation to starvation and which are not. There is clinical consensus that depression/anxiety and cognitive impairments in AN mainly are sequelae to the malnutrition. However, this consensus is largely based on experimental starvation studies of healthy subjects back in 1940s and from famine- and food programs in the third world, whereas evidence from studies on AN is lacking. The main objective of the study is in the detail to elucidate the short-term changes in the psychopathological profile, depression, anxiety, and cognitive functions in relations to intensive nutritional rehabilitation with weight gain of 10-30% in a specialized medical stabilization unit. Secondarily, it is examined whether cortisol levels are associated with depression/anxiety symptomatology and cognitive impairments. The hypothesis is that an improvement in nutritional status over a short time leads to clinically significant improvements in psychopathology and cognitive functions, which remain 2-3 months after discharge, making the patients more accessible to psychotherapy.
The purpose of this study is to compare the efficacy, safety, and cost-effectiveness of lower calorie refeeding versus higher calorie refeeding in hospitalized adolescents with anorexia nervosa.
The purpose of this study is to test the therapeutic effects of a computerized attention training for patients with Anorexia Nervosa (AN). The primary aim is to determine if a computerized attention training can modify attention towards food and ameliorate eating disorder symptoms and related difficulties, such as anxiety. The secondary aim is to explore underlying mechanisms that contribute to these improvements. The stability of potentially observed effects over a one-month period will also be determined.
Decreased bone strength is a common and serious medical problem present in many women with anorexia nervosa. Women with decreased bone strength are more likely to suffer broken bones than women with normal bone strength. This study will investigate whether the use of transdermal estrogen can improve bone mineral density (BMD) and bone microarchitecture in women with anorexia nervosa anorexia nervosa when used for 6 months.
To determine efficacy and safety of Sipjeondaebo-tang for Cancer patients suffering from anorexia after chemotherapy. Sipjeondaebo-tang will be administered for 4 weeks, 3 times per day after a meal. Changes of FAACT scale, Anorexia VAS, Weight, BMI, Clinical laboratory test such as ACTH, Cortisol, Chrelin, IL-6, ESR, CRP will be measured and analyzed.
This study is aimed to determine clinical characteristics of patients with anorexia nervosa and outcome of treatment at Sirirraj Hospital.
