Filter by:The purpose of this study is to identify alterations of motivational processes related to decision making in uncertainty condition associated with gambling addiction: by studying the dynamics between brain systems involved in decision making and motivation.
The study is intended to identify gene polymorphisms significantly associated with specific behavioral- and preoccupation-typologies of sexual addiction, and to identify additional potential genetic markers of sexual addiction. Research subjects with sexual addiction will be identified from the out-patient and in-patient populations of the investigative sites. Research subjects in the Control Group will be identified from the general population and from the student body of selected colleges. Approximately 1100 subjects will be enrolled in the study. Anticipating 10% drop-out, this is intended to generate a population of approximately 500 men and women clinically diagnosed with sexual addiction, and approximately 500 healthy men and women who do not meet diagnostic criteria for sexual addiction nor have psychopathology who will serve as the control population.
Among youth, the prevalence of mental health and addiction (MHA) disorders is roughly 20%, yet youth are challenged to access services in a timely fashion. To address MHA system gaps, this study will test the benefits of an Integrated Collaborative Care Team (ICCT) model for at-risk youth with MHA challenges. In partnership with community agencies, adolescent psychiatry hospital departments, and family health teams, investigators have developed an innovative model of service provision involving rapid access to MHA services. This model will be implemented and compared to the usual treatment youth receive in hospital-based, outpatient, mental health clinics in Toronto. A rapid, systematic, approach to MHA services geared to need in a youth-friendly environment is expected to result in better MHA outcomes for youth. Moreover, the ICCT approach is expected to decrease service wait-times, be more youth- and family-centred, and be more cost-effective.
The purpose of this study is to evaluate the relative exposures of lofexidine and its major metabolites in subjects seeking buprenorphine dose reduction.
The neurobiological underpinnings of obesity point to brain asymmetry in cortical and deeper brain regions. Furthermore, chemical, structural and functional imbalance in cortical and sub-cortical brain regions alters reward processing, attentional control and self-regulation in food-addicted obese individuals. In this study the investigators use TMS with a special multichannel H-coil developed by their lab to safely stimulate cortical and deeper brain regions in obese humans. The investigators aim to produce interhemispheric neuroplasticity (INP) using a paired associative stimulation (PAS) protocol over the DLPFC, to restore neurobiological functioning, alleviate food addiction symptoms, and promote weight loss.
To evaluate addiction remission and addiction transfer after bariatric surgery.
The purpose of this study is to quantify the serious risks of prescription opioid misuse or abuse or opioid use disorder (OUD) associated with the long term use of opioid analgesics for management of chronic pain, among patients prescribed opioid products.
The repetitive transcranial magnetic stimulation (rTMS) will be used to treat amphetamine-type stimulant (ATS) addiction.
Our hypothesis is that the conventional treatment of Behavioral Addiction in Parkinson's disease is often not effective, and that affects the motor aspects (worsening akinéto-rigid syndrome and / or worsening of dyskinesia due to higher levodopa doses to compensate for the drop in behavioral addictions) and non-motor (withdrawal syndrome dopamine agonist) anxiously including apathy. Our goal is to describe the natural history of Behavioral Addiction under the effect of the evolution of the disease and adapt treatment according to the prior art, through a study of a larger population of patients than in the few published studies.
The purpose of this study is to formulate definitions of doctor/pharmacy shopping and evaluate its association with abuse/addiction
