Active clinical trials for "Bipolar Disorder"

The purpose of this protocol is to allow for the careful screening of patients and healthy volunteers for participation in research protocols in the Experimental Therapeutics and Pathophysiology Lab (ETPB) at the National Institute of Mental Health (NIMH) and for the collection of natural history data. In addition the protocol will allow clinicians to gain more experience in the use of a variety of polysomnographic and high-density EEG recordings. Subjects in this protocol will undergo an evaluation which may include: a psychiatric interview; a diagnostic interview; rating scales; a medical history; a physical exam; brain magnetic resonance imaging (MRI); electroencephalography (EEG); electrocardiography (EKG), magnetoencephalography (MEG); blood, saliva and urine laboratory evaluation; and a request for medical records. Subjects may also be asked to complete questionnaires about attitudes towards research and motivation for research participation. The data collected may also be linked with data from other mood and anxiety disorder protocols (e.g., brain imaging, DNA, psychophysiology tests, treatment studies, etc) for the purposes of better understanding the diagnosis, pathophysiology, and treatment response of patients with mood disorders. Parents of minors will be interviewed. Upon conclusion of the screening process, subjects will either be offered participation in a research protocol and will sign the appropriate informed consent, or will be considered not appropriate for participation in research and will be referred back into the community. The current protocol thus serves as an entry point for individuals with mood or anxiety disorders or healthy volunteers to enter NIMH IRB approved ETPB protocols....

Mood disorders (including bipolar disorder and major depressive disorder) are chronic mental disorders with high recurrent rate. The more the number of recurrence is, the worse long-term prognosis is. This study aims to establish a prediction model of recurrence of manic and depressive episodes in mood disorders, with a hope to detect recurrence relapse as early as possible for timely clinical intervention. We will adopt wearable smart watch to collect heart rate, sleep pattern, activity level, as well as emotional status for one year long in 100 patients with bipolar disorder, and annotated their mood status (i.e., manic episode, depressive episode, and euthymic state). We expect to establish prediction models to predict the recurrence of mood episodes.

At present, diagnosis and recognition of depression and bipolar disorder are mainly based on subjective evidence such as clinical interview and scale evaluation. The corresponding diagnosis basis has some shortcomings, such as poor diagnostic reliability and failure in early identification of bipolar disorder. Therefore, it is of great significance to explore objective diagnostic indicators to remedy the deficiencies. Therefore，the investigators collect psychological and physiological information data of patients with bipolar disorder and depression.Then the investigators aim to construct and verify the multidimensional emotion recognition model to analyze the personality characteristics, negative emotions and cognitive reactions of different individuals, and form a systematic accurate recognition and evaluation tool.

This research study is designed to look at the involvement of the glutamate system and synaptic density in depression and bipolar disorder. Each participant will undergo a screening appointment to determine study eligibility. Thereafter, the study will take 2 or 3 visits depending on schedule availability and will consist of a combination of one magnetic resonance imaging (MRI) or functional magnetic resonance imaging (fMRI) scan, one proton magnetic resonance spectroscopy (MRS) and/or one C13 MRS scans, and up to two positron emission tomography (PET) scans. Participants will also participate in cognitive testing. Depending on camera time, staff availability and subject schedule, total study participation may last 1-2 months.

The objective of this protocol is to establish a comprehensive screening process for the evaluation of eligibility for entry in a clinical trial program for children and adolescents with bipolar disorder.

Evidence suggests that mGLUR5 availability may play a key role in the biology of mood disorders. This study aimed to investigate the changes in metabotropic glutamate receptor 5 (mGLUR5) availability and clinical symptoms in patients with MDD and bipolar disorder(BD) after two months of vortioxetine treatment. The investigators hypothesized that patients with MDD and BP have abnormal mGluR5 availability in certain brain regions, and baseline mGLUR5 availability can predict prognosis the prognosis of MDD and BD. fMRI and NODDI are also used to evaluate the function or neurite condition at baseline and 8 week

The purpose of this study is to use eye-tracking technology to study attentional biases, reward sensitivity, and cognitive control in adult patients with bipolar disorder with or without anxiety and/or substance use disorder comorbidity.

The investigators hypothesize that implementation of a shared decision making care plan for prophylactic treatment will help therapeutic adherence of bipolar patients. They also anticipate that patients treated according to a shared decision making plan will have an elevated satisfaction of their care, quality of life and functionment, as well as a lower number of relapses

To describe the broad spectrum of Bipolar Disorder patients admitted to out-patient and in-patient psychiatric departments in Norway. Include all admitted Bipolar patients both with and without co-morbid disorders.

We are the missing link in clinical trials, connecting patients and researchers seamlessly and conveniently using a mobile health platform to advance medical research. We make it easy for patients to contribute to research for medical conditions that matter most to them, regardless of their location or ability to travel.
