Filter by:The ultimate goal of this study is to find the association between specific polymorphism of candidate genes and medication response in attention deficit hyperactivity disorder (ADHD) patients. These results will lead the investigators' team: (1) to resolve controversies over inconsistent findings in previous pharmacogenetic studies; (2) to study the medication effect on the neuropsychological functions that are useful candidate endophenotypes for ADHD; (3) to delineate the nature and the effect of gene-gene interaction in the drug response of ADHD patients.
To understand whether a relationship exists between eating disorders and ADHD, we seek to clarify the prevalence of ADHD in individuals with eating disorders. To this end, we will estimate the prevalence of ADHD, and other neuropsychiatric disorders, in outpatients with history of an eating disorder diagnosis. Secondarily, we will identify patterns of cognitive deficits in outpatients with history of an eating disorder diagnosis. We will also examine whether ADHD in this population is associated with functional and familial correlates associated with ADHD.
In a randomized clinical trial, the researchers want to investigate if the positive short-term outcomes (first 1-2 years), achieved with specialized assertive intervention programme (OPUS), can be maintained for five years if the specialized treatment is sustained over the first five years in comparison to only two years of specialized treatment followed by three years of standard treatment.
The aim of the protocol is to better understand the impairments in visual processing, as such impairments may induce social interaction difficulties in subjects with autism spectrum disorders (adults and children) and schizophrenia, like face exploration.The same protocol will be used for the three populations, each population being compared with matched controls. The explorations are designed to test two different hypotheses regarding the mechanisms of the visual perception difficulties of the two populations. Even though difficulties to extract the global form of objects have been described in both subjects with autism and schizophrenia, we will test two different hypotheses for the two populations. We will test the hypothesis that subjects with autism display an advantage for the processing of local information arising at an early level of processing, whereas disorders observed in patients with schizophrenia originate from attention disorders. The protocol includes three consecutive studies, each one being applied in each of the three populations.
The objectives of this study are to evaluate the efficacy and safety of quetiapine extended release tablet versus placebo as adjunct to selective serotonin reuptake inhibitors/serotonin/norepinephrine reuptake inhibitors (SSRI/SNRI) in the augmentation treatment of patient with primary anxiety disorders or mood disorders with co-morbid anxiety symptoms.
The purpose of this research study is to learn about the efficacy of a medication called varenicline (Chantix) in treating ADHD in adults and in reducing cigarette smoking in adults with ADHD. The investigators hypothesize that ADHD symptomatology in adults with ADHD will be improved with varenicline treatment. The investigators also hypothesize that varenicline treatment will result in significant reductions in cigarette smoking. Another objective of this study is to more fully evaluate the response and tolerability to varenicline in this group of cigarette smoking adults with ADHD.
This study will investigate and contrast the effects of two psychological treatments for adults with autism spectrum disorder. Cognitive Enhancement Therapy (CET) is a cognitive remediation intervention that aims to help adults with problems in thinking, planning, and socialization. Enriched Supportive Therapy (EST) is an individual supportive therapy that aims to help adults learn about their condition, manage their emotions and stress, improve their social skills, and cope with everyday problems.
RATIONALE: Cranial microcurrent electrical stimulation (CES) is mild electrical current received through electrodes placed on the earlobes. CES may lessen symptoms in women with breast cancer receiving chemotherapy. It is not yet known whether CES is more effective than sham therapy in reducing symptoms caused by chemotherapy in women with breast cancer. PURPOSE: This randomized phase III trial is studying mild electrical stimulation to see how well it works compared with sham therapy in reducing symptoms caused by chemotherapy in women with stage I, stage II, or stage IIIA breast cancer receiving chemotherapy.
RATIONALE: Collecting and storing samples of blood from patients with cancer to test in the laboratory may help the study of cancer in the future. PURPOSE: This research study is collecting and storing blood samples from patients with cancer.
RATIONALE: Studying blood samples from cancer patients undergoing pain treatment in the laboratory may help doctors learn more about how pain drugs work in the body. It may also help doctors predict how patients will respond to treatment. PURPOSE: This research study is looking at fentanyl in patients with cancer.
