Active clinical trials for "Depression"

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

This study will evaluate a possible tool for predicting future effectiveness of bright light in treating seasonal affective disorder, winter subtype, and will examine secondary effects of bright light on cardiovascular risk factors.

To examine the role of depression on risk for cardiovascular disease in twins.

This is a study investigating the hormones and substances important to the stress response. The hormone that is most directly responsible for stress response is called corticotropin-releasing hormone (CRH). CRH is produced in the hypothalamus of the brain and causes the pituitary gland to produce another hormone called ACTH. The hormone ACTH then acts on the adrenal glands causing them to produce the hormone cortisol. Unfortunately, CRH levels are unable to be measured in simple blood samples. However, substances like cortisol and leptin can provide information as to the activity of the hypothalamus. The hormone leptin is associated with the regulation of body weight and the normal maintenance of bodily functions (homeostasis). It is found in fat cell (adipocyes) and communicates the nutritional status of the body to the brain (central nervous system). Research using animals has shown that defects in the communication between leptin and the brain causes obesity (the state of being overweight). It has also been noted that obese humans tend to have high levels of leptin. By studying patients with abnormal genes responsible for leptin production, researchers have found that a least one leptin gene must be intact for the normal secretion of hormones to proceed. These results show that the hormone leptin is produced outside of the brain in fat cells and acts directly on the function of the hypothalamus within the brain. Researchers believe that leptin plays a key role in the normal release of hormones from the HPA axis. Researchers intend on continuing to study the role of leptin in fat distribution, and the activity of the HPA axis in normal volunteers. In addition, this study will focus on the role of leptin in depression, because depression is characterized by changes in food intake, body weight, and neuroendocrine function. Data gathered from this study will provide a better understanding of the causes and medical consequences of major depression.

Postpartum depression (PPD) is one of the most common psychiatric complications of pregnancy and postpartum. It is often defined as an episode of depressive disorder that occurs in the postpartum period. Evidence suggests that PPD has serious consequences on the quality of life of all family members, increases the risk for familial conflicts, leaving great negative effects on maternal-infant interaction. The aim of our study was to investigate and shed the light on the determinants of development of PPD mainly maternal age among women in Jordan. We also aimed at examining additional factors on prevalence of PPD and providing more information on PPD among Jordanian mothers.

Anxiety and depression in later life are highly prevalent, often appear as comorbid disorders, and have many adverse consequences for both the individual and society. Given the disease burden, the large influx of new cases, and the economic costs, efforts should be made to prevent the onset of anxiety and depression in later life. Preventive interventions are likely to become more cost effective when they are targeted at elderly who have been exposed to risk factors known to be predictive of the onset of anxiety and/or depression. As the population aging is speeding up, senile diseases have become a significant and severe public health problem, influencing national health. More than 20 million elderly patients undergo surgery each year in China, accounting for a quarter of the population who undergo surgery. Therefore, it is necessary to construct a predictive model of anxiety and depression in perioperative elderly hospitalized patients

Electroconvulsive therapy is a safe and effective therapeutic strategy in patients with treatment resistant depression. As relapse after successful ECT is significant even with adequate pharmacological strategies, continuation (up to 6 months after completion of index-ECT) or maintenance ECT (more than 6 months after index-ECT) is often necessary to maintain remission. During the current Covid-19 pandemic hospitals redirected resources and closed or significantly diminished ECT services. In this study we aim to assess the impact of discontinuing maintenance electroconvulsive therapy in patients diagnosed with unipolar depressive disorder.

The goal of this study is to refine and test a strategy for engaging veterans with symptoms of depression and/or anxiety as volunteers to help English language learners (ELLs) improve their speaking skills via structured conversations using videoconferencing.

A high-quality broad-spectrum cannabidiol supplement with a bio-terpene complex will be administered once daily. It is hypothesized that this supplement will lead to improvements in sleep, focus, and stress. Previous research supports that CBD supplementation provides support to the endocannabinoid system, allowing the brain to better control negative psychological outcomes like fear, stress, and negative mood states.

Participants will be asked to fill out an online questionnaire about their demographics information and all 42 items from the Depression Anxiety Stress Scale (DASS-42). A series of machine learning techniques will be applied to the dataset to develop a shortened assessment using the most important demographics and DASS-42 items from the original questionnaire, to predict depression levels indicated by DASS-42.
