Active clinical trials for "Bipolar Disorder"

The purpose of this study is to use brain imaging technology to examine the role of certain brain receptors and the nervous system chemical acetylcholine in major depression. The cholinergic system involves the regulation of neurotransmitters and the brain receptors to which they bind. Evidence suggests that the cholinergic system may play a role in the development of depression. Acetylcholine is a neurotransmitter that binds to certain brain receptors called muscarinic cholinergic receptors. Cholinomimetic drugs (drugs that stimulate the cholinergic system) often exacerbate depressive symptoms in people with mood disorders and in healthy individuals. This increase in depressive symptoms may be caused by stimulation of muscarinic acetylcholine receptors (mAChRs), but further study is needed to confirm this. This study will use positron emission tomography (PET) and magnetic resonance imaging (MRI) to study the function of mAChRs in individuals with depression. Participants in this study will undergo a physical examination, psychiatric interviews, neuropsychological tests, PET and MRI scans, and rating scales of depression, anxiety, and negative thinking symptoms. Questions about behavior and functioning will be asked and blood samples will be collected for genetic analysis.

This study will examine how various factors, such as psychiatric symptoms, gender, social support, substance use, and attitudes toward medication, affect treatment adherence in individuals with bipolar disorder.

The primary aim of this study is to use proton magnetic resonance spectroscopy to look at myo-Inositol containing compounds (Ino) and creatine + phosphocreatine (Cr) in the anterior cingulate of 20 children with bipolar disorder between the ages of 6-17 years old free of risperidone treatment and 20 children with bipolar disorder after an eight-week or longer treatment with risperidone. For comparison, results will also be obtained from 20 controls (without bipolar disorder or ADHD) of the same age and gender as well as from 20 children or adolescents with a diagnosis of Attention Deficit Hyperactivity Disorder. We hypothesize that Ino/Cr levels in the anterior cingulate will correlate positively with manic symptoms using the Young mania rating scale (YMRS). Ino/Cr levels in the anterior cingulate in the anterior cingular gyrus will be lower in subjects who have received eight weeks or longer of risperidone

The purpose of this study is to find out how well new treatment plans are followed by outpatients with major mental illnesses (schizophrenia, bipolar disorder, depression, personality disorder) and to determine the relationship between a diagnosis of schizophrenia and compliance with a treatment plan.

To reassure the clinical study data on Seroquel antidepressant efficacy in patients who are diagnosed as bipolar depression

For many years researchers have been trying to better understand the regulation of sleep and activity by studying circadian (daily) rhythms of human beings. It appears that the hormones estrogen, progesterone, and testosterone play a role in the regulation of circadian rhythm in animals. Researchers believe these hormones may also play a similar role in the regulation of human circadian rhythms. Little research has been conducted on how these hormones affect human circadian rhythms. This study is designed to learn more about how specific hormones influence men and women's daily rhythms. This study will use women from another research study being conducted at the NIMH called, "The central nervous system effects of pharmacologically induced hypogonadotropic hypogonadism with and without estrogen and progesterone". Male subjects will be recruited from another NIMH study called, "The central nervous system effects of pharmacologically induced hypogonadotropic hypogonadism with and without testosterone replacement". In order to test the possibility that gonadal steroids (estrogen, progesterone, and testosterone) change circadian rhythms and the sleep-wake cycle in humans, participants will undergo chronobiologic evaluations. The chronobiologic evaluations will look at sleep and rest periods, activity as measured by a wrist monitor, and 24 hour inpatient electroencephalograph (EEG), rectal temperature, and melatonin monitoring.

This study is for subjects with a diagnosis of bipolar disorder who have depression at the time of recruitment. It involves brain imaging with an MRI (magnetic resonance imaging) and PET scan (positron emission tomography) and treatment with an antidepressant. The medication involves adding an SSRI (either celexa/citalopram or prozac/fluoxetine) to a mood stabilizer.

The current research project aims at investigating whether it is possible to obtain an increase in physical activity among inpatients with schizophrenia spectrum disorders by the use of motivational interviewing and environmental interventions, and whether interventions will be associated with an increase in physical fitness and/or improvement in mental health. The Norwegian health care system operates with a catchment-area based organization, which make high levels of representability of patients possible. Patients will be recruited from intermediate-long term inpatient departments where patients typically have schizophrenia spectrum disorders and are admitted for longer periods. There are thus unique possibilities for coordinated efforts to motivate for and change dysfunctional habits.

Bipolar Disorders (BD) typically involve repeated episodes of both depression and excessively high mood or irritability (hypomania or mania). BD presents considerable challenges for the individual, his or her supporters, and society more generally. Medication is generally considered to be the mainstay treatment, however a substantial number of individuals with BD continue to experience episodes despite use of medication. Furthermore, ongoing mood instability either outside of episodes, or as the main feature of their BD, is a significant difficulty experienced by many. Whilst studies suggest that certain psychological therapies can be helpful for people experiencing full bipolar episodes, or to reduce risk of future episodes, there are no evidencebased psychological therapies available for individuals experiencing ongoing mood instability. Dialectical Behaviour Therapy (DBT) was developed several decades ago as an approach for people with Borderline Personality Disorder. DBT aims to give individuals who experience rapid and intense shifts in affect skills for managing this. Despite the many similarities in the symptoms experienced by individuals with Borderline Personality Disorder and those with Bipolar Disorder only a small number of studies have tested DBT for BD, and no studies to date have specifically investigated DBT as a means to help individuals with ongoing mood instability. We have developed a version of groupbased DBT that draws upon our own research to adapt standard DBT for this client group (DBTBD). The group is designed to be delivered efficiently within the U.K. healthcare system whilst meeting the needs of individual participants through use of additional individual sessions and a mobile phone application. The current study investigates how acceptable DBTBD is to clinicians and patients, and whether - for the small number of individuals in the study -changes in symptoms and key ways of thinking and behaving appear to take place across the period of treatment.

The purpose of this observational study is to evaluate the use and short term safety of Asenapine (Sycrest) in real-life usage in the Mental Health Trust Setting in the United Kingdom(UK) National Health Service (NHS). The study is to be carried out independently by the Drug Safety Research Unit (DSRU) in Southampton, although it is funded by Merck, the manufacturer of Sycrest.
