Active clinical trials for "Bipolar Disorder"

The purpose of this study is to estimate adherence to treatment in bipolar patients, to characterize patients based on adherence degree and to describe the variables linked to poor adherence to treatment in real-life practice.

A registry study to identify the patient-diagnosis-treatment characteristic profile of patients with bipolar disorder in Turkey.

The primary objective of this study is to assess the proportion of schizophrenic patients and the proportion of bipolar patients who discontinue olanzapine within 12 months of treatment in outpatient, ambulatory or community settings

The purpose of this study is to identify genetic predictors of lithium response in bipolar disorder.

The purpose of this project is to use behavioral techniques to investigate emotional processing in subjects with major depression and healthy comparison subjects.

Bipolar disorder is a mood (affective) disorder characterized by the occurrence of alternating feelings of excitement (mania) and depression. It is a common, but serious condition, and potentially life-threatening. Patients are considered to have a rapid cycling form of bipolar disorder if they experience four or more episodes of hypomania (mild degree of mania), mania, and/or depression. Approximately 20% of the patients in bipolar clinics have the rapid cycling form of the disorder. Therefore it can be said that RCBD is not a rare condition and that it can severely impair a patient. These reasons alone justify studying RCBD. However, researchers also believe that information gathered by studying patients with RCBD can be used while studying other patients with different forms of bipolar disorder. The purpose of this study is to screen patients diagnosed as having rapid cycling bipolar disorder to see if they fit the criteria for the diagnosis and to see if they would be interested in participating in other research studies. Patients will undergo diagnostic interviews, physical examination, routine blood tests, EKG (electrocardiogram), and complete self-rating forms as part of the screening process.

There is some cognitive impairment in patients with bipolar depression. THINC-it is a simple, fast and free cognitive assessment tool. It has good reliability and validity in patients with depression, but its application in patients with bipolar depression is not clear. The purpose of this study is to verify the reliability and validity of THINC-it cognitive test in bipolar depression, and to further explore the difference of cognitive impairment between attack and remission of bipolar depression, so as to provide empirical research basis for clinical evaluation-based treatment.

The objective of this project is to determine the concordance between the subjective and objective evaluation of cognitive functions in affective patients in partial remission through scales and cognitive tests that would be easily implemented in the different mental health care devices. This is a cross-sectional case-control study of non-probabilistic sampling, which will include a group of patients diagnosed with Major Depressive Disorder and Bipolar Disorder and a group of healthy controls from the same population and matched by age, gender and years of education with the group of patients. Patients will be recruited from the psychiatric service of the Hospital de la Santa Creu i Sant Pau who meet the inclusion criteria, and they will undergo a blood draw, a clinical assessment, a complete neuropsychological examination together with scales of subjective perception of cognitive deficit, a measure of cognitive reserve and an evaluation of psychosocial functionality. In addition, the same evaluation will be made to a group of healthy subjects.The total sample will be 120

The primary objective of the study is to evaluate the feasibility of eliciting continuous narrative speech in different neurodegenerative and psychiatric indications, using remote, self-administered speech tasks, as measured by the average length of speech elicitation for each speech task during the first week of self-assessment. Secondary objectives include (1) evaluating the reliability of speech tasks in the remote self-administered setting, as measured by the intra- and inter-subject variance; (2) accessing the adherence of speech tasks in this setting, as measured by the subject average fraction of days during the first week, where at least one task response is submitted; (3) evaluating the feasibility of using speech tasks in the setting of a telemedicine videoconference, as measured by the average length of speech elicited in each group; (4) evaluate whether a set of acoustic and linguistic patterns can detect each indication, compare to either a control group or all other indications, as measured by the area under the receiver operating characteristic curve (AUC), sensitivity, specificity and Cohen's kappa of the relevant binary classifier; (5) evaluating how the performance of such algorithms can be impacted by speaker and environment covariates, as measured by the Kendall rank correlation coefficient of the AUC of each classifier and each of age group, gender and speech-to-reverberation modulation energy ratio.

In this study we tried to elucidate the factors associated with the development of a rapid cycling course in bipolar disorder patients, in a prospective and longitudinal design, and the role of antidepressants. The identification of risk factors is extremely relevant from the clinical point of view. We hypothesized that rapid cycling bipolar disorder is associated with more chronicity, poor outcome, and more antidepressant prescription.
