Filter by:One of the main points in the biological trends is, the circadian rhythm and disturbance in this cycle, which cause mood disorders and irregularity in this bio clock, to get depression. The pineal gland with the precise regulation of circadian rhythm of melatonin regulates the brain haemostasis. The abnormal function of this gland gives rise to psychiatric disorders. In the period of youth and early of middle-age cause biochemical changes and disturbance in biorhythm including melatonin secretion. This process can change the peak of melatonin phase. In addition, a decrease in the level of serum melatonin, can change the function of immune system of depressed patients. This function facilitates the process of cancerous cell formation and tumor growth. With respect to the conflicting results and that the positive and negative roles of melatonin in the creation of depression is unknown, the aim of this study was to compare the morning and nocturnal serum melatonin rhythm levels in the patients with Major Depressive Disorder. The second purpose was to measure the morning and nocturnal serum melatonin levels in the depressed and healthy men and women.
The purpose of this study is to assess the efficacy, safety and tolerability of 8-week treatment with Vortioxetine (Lu AA21004), once daily (QD), in Japanese participants with major depressive disorder. The purpose of this study is to assess the efficacy, safety and tolerability of 8-week treatment with Lu AA21004, once daily (QD), in Japanese participants with major depressive disorder.
This is a non-interventional study to review safety data on administration of desvenlafaxine succinate among Filipino patients with MDD and VMS per usual clinical practice within the first three years post commercial distribution.
The study will only detect hypomanic symptoms in treatment resistant MDD patients by mean of HCL-32 administration. Further re-evaluation of MDD diagnosis is not a direct aim of the study. No efficacy and tolerability of pharmacological treatments will be assessed. Patients matching inclusion and exclusion criteria will be enrolled consecutively; each investigator will include the first 10 to 40 patients that will be visited as treatment resistant MDD.
Primary Aim 1: Examine effectiveness of the Oh Happy Day Class (OHDC) compared to the Coping With Depression (CWD)in increasing retention, adherence, engagement, satisfaction, and treatment-seeking. The investigators hypothesize the OHDC compared to the CWD will result in greater increases in: 1a. retention, 1b. adherence, 1c. engagement, and 1d. satisfaction at the middle and end of the intervention, and 2.e. greater increase in treatment-seeking 3-, 6-, 9-, and 12- months post-intervention. Outcome measures: logs: attendance, homework completion, class-participation level; Client Satisfaction Inventory; and Cornell Service Index. Primary Aim 2: Examine effectiveness of the OHDC in reducing symptoms of depression at the middle and immediate end of the intervention, and 3-, 6-, 9-, and 12- months post-intervention. The investigators hypothesize the OHDC will result in greater reduction in depressive symptoms compared to the CWD at 3-months post-intervention. Outcome measures: Center for Epidemiologic Studies Depression Scale and Quick Inventory of Depression Symptoms. Secondary Aim 3: Examine the effectiveness of the OHDC in improving self-reports of mental and physical health status and reducing self-reports of perceived disability. The investigators hypothesize the OHDC compared to the CWD will result in greater self-report of: 3a. improved mental and physical health status, and 3b. reduced self-report of disability at the immediate end of the intervention and 3-,6-, 9-, 12- months post-intervention. Outcome measures: SF-12 Health Survey, and World Health Organization Disability Assessment Schedule. Public Health Impact: Based on CAI research, the OHDC has the potential to be four times more effective than the CWD. If our hypotheses are proven, the OHDC will be the first evidence-based culturally adapted depression intervention designed specifically for African American men and women between the ages of 30-60.
Obtain phenotypic data and a DNA/blood sample from mood disorder patients undergoing pioglitazone or quetiapine XR treatment as a part of an IRB approved clinical trial conducted at the Mood Disorders Program. Pioglitazone treatment is examined in metabolic syndrome comorbid with bipolar depression (IRB # 07-08-24) and unipolar depression (IRB # 07-07-20). Quetiapine XR treatment is examined in generalized anxiety disorder comorbid with bipolar depression (IRB # 10-06-19) and unipolar depression (IRB # 12-01-29). Please refer to the respective IRB protocols for more information.
The purpose of this observational study is to study specific outcomes of interest in users of quetiapine compared with all other atypical antipsychotics and specifically olanzapine and risperidone. The outcomes of interest are all-cause mortality, failed suicide attempts, extrapyramidal symptoms, diabetes mellitus, hypothyroidism, acute myocardial infarction and stroke. This retrospective cohort study is based on population-based record linkage system (PHARMO RLS) capturing about 2.5 millions residents in the Netherlands.
The purpose of this study is to determine the safety and effectiveness of a nutritional supplement, the probiotic bacteria GanedenBC30. Probiotics are live microorganisms which when taken in large enough amounts are supposed to provide a health benefit. The investigators would like to see whether this supplement can be used as a treatment for Irritable Bowel Syndrome (IBS) and Major Depressive Disorder (MDD). Participants in the study will have both IBS and MDD. In order to find out if GanedenBC30 is effective in treating IBS and MDD, the investigators will compare it to a placebo. About 32 people will take part in this research study. About half of these 32 people will take part at Charles River Medical Associates and half will take part at Burlington Medical Associates. Participants will be recruited from among patients already being seen at Charles River Medical Associates or Burlington Medical Associates for their primary care. The study will last for two months, during which time participants will make eight study visits and will take either Ganeden BC30 or placebo. The investigators hypothesize that subjects treated with the probiotic will have significantly better outcomes with regard to depression and IBS symptoms compared to those who receive placebo.
The primary aim of the study is to evaluate the efficacy of a systematic training of general affect regulation skills (ART) on the reduction of depressive symptom in individuals meeting criteria for major depressive disorder (MDD).
This study aims to determine whether using telecommunication tools, specifically web pages containing online screening instruments and real-time video chat, will be an efficient way to implement Major Depressive Disorder screening among college students. The study also aims to determine if proactive depression screening and free online consultation with a psychiatrist will increase the rate of help-seeking among college students with MDD. Eligible participants will complete a demographics survey and depression screening assessment online. Those subjects who express suicidality or depressive symptoms will be offered the opportunity to complete a one-time psychiatric consultation with Skype video-conferencing.
