Filter by:The goal of this clinical trial is to learn about cognition in psychotic disorders (schizophrenia, bipolar disorder, and schizoaffective disorder). The main question it aims to answer is: Can we use magnetic stimulation to change processing speed (how quickly people can solve challenging tasks). Participants will be asked to perform cognitive tasks (problem-solving) and undergo brain scans before and after transcranial magnetic stimulation (TMS). TMS is a way to non-invasively change brain activity. Forms of TMS are FDA-approved to treat depression and obsessive compulsive disorder. In this study, we will use a different form of TMS to temporarily change brain activity to observe how that changes speed in problem-solving.
Most psychiatric research is based on the nosographic classifications used in current practice. At present, there is no diagnostic or prognostic biomarker for psychiatric pathologies commonly used in clinical practice. The study hypothesis is that peripheral inflammatory biomarkers could be common to several psychiatric disorders, in particular psychotic disorders (bipolar disorder, schizophreniform disorder, schizophrenia, depressive episode with psychotic features). The aim of this project is to set up a bio-collection of biological samples (peripheral blood samples) with associated phenotypic data (assessment of various symptoms using standardized scales in patients whose blood is sampled). The setting up of this cohort follows on from work carried out on a PsyCourse cohort also using a transdiagnostic approach in psychiatry, in order to be able to collaborate within a European research project.
Bipolar disorders are mental illnesses characterized by the recurrence of mood-episodes, that can have a severe impact on the life of individuals. The effect of lithium, one of the main medications used to treat acute episodes or prevent them from happening, is very different from one individual to an-other. So far, there is no way to predict in advance for whom patient this treatment will be effective or for whom it will not. Finding markers that can predict as early as possible the efficiency of this treatment is a major field of current research in psychiatry, in order to avoid maintaining an inefficient treatment for several years that can have negative side-effects. Over the past decades, it has been shown by multiple studies that lithium can act on the biological clock, that regulates circadian rhythmicity of the body (i.e. rhythms that presents a 24 hours periods, such as rhythms of sleep and activity, feeding, social activities...). But it is still very unclear whether the effect of lithium in regulating the mood in bipolar disorders is mediated by this action. Melatonin is one of the key-regulator of circadian rhythmicity of the human body. Our hypothesis, based on some previous studies, is that the action of lithium in type-1 bipolar disorder (BD-I) is related to an action on melatonin secretion. To test that, we want in this study to compare the noctunal secretion of melatonin between BD-I individuals with a good response to lithium versus with a poor response to lithium.
The main aim of this research is to explore the effects that ketamine has on the functional connectivity of the brain in participants with treatment resistant depression (TRD). This study will investigate the relationship between these changes and response to treatment as measured by clinical scales, as well as examining drug induced changes in reward and emotion based brain activity, structural connectivity, cerebral blood flow, cognition, metabolism and blood markers of brain plasticity.
To initiate a low-carbohydrate, high-fat (LCHF) or ketogenic dietary (KD) intervention among a cohort of outpatients with bipolar illness who also have metabolic abnormalities, overweight/obesity, and/or are currently taking psychotropic medications experiencing metabolic side effects.
The goal of this study is to evaluate the feasibility and potential benefit of a behavioral intervention designed to improve emotion regulation in individuals with bipolar disorder. The intervention consists of game-like exercises that involve the 'Cognitive Control of Emotion (CCE) - i.e. the ability to control the influence of emotional information on behavior. Deficits in the cognitive control of emotion are a central feature of Bipolar Disorder that contributes to emotion dysregulation, maladaptive mood episodes, and, ultimately, the overall chronicity and severity of illness. Neuroimaging studies of bipolar patients demonstrate neural abnormalities in brain systems involved in cognitive control and emotion processing. Furthermore, these abnormalities predict mood and behavior problems associated with cognitive control of emotion, such as emotion lability, disinhibited behavior, and extreme mood states. The aim of this study is to determine feasibility and examine whether a computer-based program of progressively difficult cognitive control emotion exercises will improve cognitive control of emotion skills and, thereby, result in better emotion regulation and daily functioning in young adults with bipolar disorder. To test the intervention, a single group of young adults (18-30 years old) with Bipolar I Disorder will complete behavioral assessments before and after 20 hours (4 weeks) of CCE training. In order to identify baseline deficits associated with bipolar disorder, a comparison group of healthy young adults will complete behavioral assessments at a single time-point (without CCE training).
This is a study of the efficacy and safety of BXCL501 in children and adolescents with acute agitation and either bipolar disorder or schizophrenia.
To investigate the safety for an observation period of 52 weeks with use of Abilify prolonged release aqueous suspension for intramuscular (IM) injection in patients with bipolar I disorder for prevention of recurrence/relapse of mood episodes in the routine clinical setting. The early stage safety after the switching from oral aripiprazole to this IM injection is investigated including extrapyramidal syndrome and malignant syndrome. Information regarding efficacy is collected as well.
Mood disorders are associated with significant financial and health costs for the United States, partially due to cognitive problems in these patients that can worsen disease course and impair treatment response. This study proposes to use smartphone-based technology to monitor cognitive problems in patients with mood disorders by linking brain network changes with predicted worsening of mood symptoms. The proposed study will provide evidence for using smartphone-based passive sensing as a cost-effective way to predict illness course and treatment response.
The objective of this study is to determine whether the practice of a non-drug related intervention technique (behavioral modification technique consisting of a combination of breathing exercises, cold exposure and meditation) has an effect on long-term cannabinoid receptor function in a control group as well as in a group of patients suffering from bipolar affective disorder (BAD). Specifically, the objective of this study is to test whether the applied behavioral modification technique is able to alter cannabinoid receptor density in brain areas that modulate mood and motivational drive (such as vmPFC, PAG, VTA, amygdala and OFC). The investigators believe that these studies will form the impetus for a better understanding and deployment of non-drug related treatment methods in patients with various depressive symptoms. In particular, it appears that the proposed behavioral modification technique might be a powerful, currently under-appreciated, method to positively modulate the brain's own cannabinoid system.
