Filter by:This trial aims to assess the efficacy and tolerability of Magnetic Seizure Therapy (MST) as an alternative to electroconvulsive therapy (ECT) for Bipolar Disorder (BD). Research indicates that the prevalence of treatment resistance in bipolar depression is twice that of unipolar depression. The limited effectiveness of current treatments for bipolar depression coupled with the medical and economic burden associated with the disorder engenders a need for novel therapeutic interventions that can provide greater response and remission rates.
Through a recent cross species translational experiment, researchers have identified a set of epigenetic marks capable of predicting postpartum depression with greater than 85% accuracy. The researchers are looking to identify a group of women from both the general population and those with a history of mood disorders who are at risk for postpartum depression and obtain brain imaging data at a postpartum time period prior to the onset of depressive symptoms and compare it with those obtained during depressive episodes. The researchers will also evaluate the efficacy of postpartum depression biomarker prediction.
The main aim of this research is to examine the potential of 5HT7 antagonists for the treatment of cognitive impairment in bipolar disorder by determining the effect of the 5HT7 antagonist JNJ-18038683 on cognitive and emotional processing related brain activity in cognitively impaired people with bipolar disorder and healthy participants using functional MRI (fMRI). This study is designed to contribute to the rational validation of 5HT7 antagonists as a treatment for cognitive impairment in bipolar disorder and to support the development of clinical trials and further drug development in this area. The study will also examine the effect of 5HT7 antagonism on brain function in healthy participants as this has never been investigated before, and to use as a comparator to determine whether 5HT7 antagonism effects disease specific impairments in task related brain activity and cerebral blood flow.
The objective of this study is to assess the changes in symptoms and cognition that occur after a 28-day abstinence period in patients with comorbid Cannabis Use Disorder (CUD) and Bipolar (Type I or II) disorder. Stabilized bipolar patients (N=52) with CUD will be randomly assigned to one of two groups: 1) A contingent reinforcement (CR) group (n=26); 2) a non-contingent reinforcement (NCR) group (n=26). The study will include a total of 8 visits to the CAMH Russell site (screening, training, baselines, week 1-4, follow-up). Participants should be between the ages of 18-60, meet criteria for CUD (moderate to severe), meet criteria for Bipolar Disorder, be on a stable dose of mood stabilizing medication(s), and be non-treatment seeking cannabis user. The visits will take up a total of approximately 22.5 hours with compensation for time provided for both groups. These visits will involve multiple clinical, substance use, and cognitive assessments. Abstinence will be maintained by weekly behavioural coaching sessions and contingency reinforcement for the CR group.
The investigators are conducting this research study to better understand how individuals with bipolar disorder regulate their emotions, and if the study can use a technique called "transcranial magnetic stimulation" or TMS to help improve emotion regulation for individuals with bipolar disorder.
This study is looking at genetic, biological, and environmental causes and how all three may work together to cause postpartum mood episodes. Participants will have psychiatric histories taken and will be monitored throughout pregnancy and during the postpartum period for the development of depressive or other mood episodes. Biological measures, including hormone levels, immunological measures, and growth factors will be collected. Environmental factors such as sleep deprivation and stress will also be measured. These factors will be considered in the setting of genetic and epigenetic data with the hope that investigators will ultimately be able to predict the onset of postpartum mood episodes in this vulnerable population.
This study aims to investigate the clinical efficacy of continuous theta burst stimulation (cTBS) on the right DLPFC as an add-on treatment in bipolar depression. The study consists of three phases. Phase 1: Bipolar depressed patients will be selected by a certified psychiatrist, who will administer (semi-)structured clinical interviews (M.I.N.I.-Plus 5.0.0, HRSD-17). The presence of exclusion criteria will be evaluated. Eligible patients will undergo MRI brain imaging for TMS neuronavigation Phase 2: Baseline clinical, cognitive and psychomotor assessments will take place. Patients will also undergo blood samples for laboratory and research assessments. TBS involves applying triple-pulse 50 Hz bursts given at a rate of 5 Hz uninterrupted trains (1). Patients will be treated with in total 20 continuous Theta Burst Stimulation (cTBS) session (900 pulses per session) over the right dorsolateral prefrontal cortex, which will be spread over 4 days. A stimulation intensity of 100% of the subject's resting motor threshold (rMT) of the right abductor pollicis brevis muscle will used. Patients will be randomized to receive either the real cTBS or sham treatment. Sham stimulation will be applied with a sham coil. The sham coil produces identical sounds but is not associated with a stimulus sensation compared to the coil delivering real stimulation cTBS. The investigators expect that real cTBS treatment and not sham will result in a significant and clinical meaningful response. Phase 3: Two post-treatment assessment moments will take place respectively 3 (max. 4) days and 10 (max. 11) days after the last treatment day. The assessments are the same clinical, cognitive and psychomotor assessments as in phase 2.
Severe mental illness (SMI) refers to the most burdensome psychiatric conditions. The need to pre-empt the onset of SMI is pressing because once SMI develops, quality of life is poor and available treatments have limited efficacy. Most risk factors for SMI are either unchangeable (e.g., genetics) or difficult to alter (e.g., low socio-economic status). In contrast, cannabis use is one specific risk factor that could be avoided. Certain individuals are more vulnerable to the harmful effects of cannabis. Genetic factors can help us identify these high-risk individuals. One in three individuals are carriers of a higher-risk genetic variant, and cannabis users with this genotype are at up to 7-fold increased risk of developing schizophrenia. In our study, genetic counselling will be provided to participants by a board-certified genetic counsellor. During the genetic counselling session, participants will have the option to receive their genotype. Participants will be counselled regarding their individualized risk of developing and of not developing SMI based on family history, whether or not they choose to use cannabis, and genotype (if the participants accept the genetic test results). The investigators hypothesize that this intervention will reduce exposure to cannabis compared to the youth who are not offered the intervention.
The purpose of this study is to validate the efficacy of Vortioxetine augmentation in bipolar disorder patients with depressive symptoms.
Bipolar disorder is a serious and chronic illness representing a major health problem with high mortality rates. According to the self-regulation model , patients had some representations of their illness which are cognitive and emotional. Cognitive representations include the set of beliefs built around the illness, its consequences and treatment. Emotional representations are negative emotions generated by the presence of the illness. According to Leventhal et al. (1997), representations are linked to information extracts by patients from society, relatives, experiences. This model has been particularly studied in the context of somatic disorders, but Baines & Wittkowski (2013) shown that it may also be relevant in patients with mental disorders. In bipolar disorders, first results show that illness representations are related to relapses and to medication adherence. That's why, we think that this relevant to improve knowledges of the psychological processes that accompany the experience of bipolar disorders. To assess illness representation, we will use both qualitative and quantitative tools. These results could have direct application to clinical practice in psychosocial interventions.
