Filter by:The purpose of this study is to find out whether prolonged treatment with methylphenidate has any adverse effect on cardiac functions and measurements.
We hypothesize that depressed patients who have not responded to their current antidepressant medication will respond to the addition of ropinirole to their current regimen at a rate better than placebo.
The following study addresses the hypothesis that cognitive-behavioral interventions will be effective in reducing positive and negative symptoms of schizophrenia under the conditions of the German health care system. It is also hypothesized that interventions designed to reduce delusions will reduce cognitive biases and dysfunctional self-concepts.
Hypothesis: Schizotypal personality disorder patients will show cognitive improvements in 1) working memory 2) learning and memory 3) sustained attention 4) enhanced performance on the AX-CPT, N-back and Eriksen during pergolide treatment. There will be a significant diagnosis by drug administration of 0.3 mg of oral pergolide interaction for performance on the cognitive tasks, with the schizotypal personality disorder group demonstrating significantly improved peformance compared to the other personality disorder group after pergolide compared with placebo. Design: Randomized, double-blind, crossover study of pergolide vs. placebo. Half of subjects receive pergolide for eight weeks; half of subjects receive placebo for four weeks followed by pergolide for four weeks.
The Pompe Registry is a global, multicenter, international, longitudinal, observational, and voluntary program for patients with Pompe disease, designed to track the disease's natural history and outcomes in patients, both treated and not. Data from the Registry are also used to fulfill various global regulatory commitments, to support product development/reimbursement, and for other research and non-research related purposes. The objectives of the Registry are: - To enhance understanding of the variability, progression, identification, and natural history of Pompe disease, with the ultimate goal of better guiding and assessing therapeutic intervention. - To assist the Pompe medical community with the development of recommendations for monitoring patients, and to provide reports on patient outcomes, to optimize patient care. - To characterize the Pompe disease population. - To evaluate the long-term effectiveness of alglucosidase alfa.
Oppositional defiant and conduct disorders are the most frequent bases for referral of children and adolescents. These disorders are difficult to treat among school-aged children and adolescents. When they become adults they are likely to manifest depressive disorders, substance abuse or dependence, and criminal behavior. These disorders are also two of the costly childhood disorders. The aim of the study is to assess the preventive effect of parent management training in preschool children at risk for oppositional defiant and conduct disorders because of high aggression scores on a parent questionnaire. It is hypothesized that given the relatively restricted costs of the intervention and the substantial costs of burden associated with these children, the intervention will be cost saving.
The goals of this study are to replicate previous findings of genetic predictors of response to clozapine and other antipsychotic drugs.
The objective of this study will be to assess the coagulation system in-vitro in a variety of bleeding and clotting disorders using the ROTEG analyzer and the thrombin generation assay.
