View clinical trials related to Major Depression.
Filter by:Background: - Studies have shown that inflammation plays an important role in depression. Brain inflammation may contribute to depression, and may make it more difficult to treat some kinds of depression with current therapies. Researchers want to use magnetic resonance imaging (MRI) and positron emission tomography (PET) scanning to study inflammation in the brain. To do so, they will use a contrast agent, which is a chemical that can show inflammation during an imaging study. Objectives: - To see if people with major depressive disorder have increased inflammation in the brain. Eligibility: - Individuals at least 18 years of age who have major depressive disorder. Design: - Participants will be screened with a physical exam and medical history. They will provide blood samples before the scanning sessions. - Participants will have a PET scan after the screening visit. They will have a dose of the contrast agent before the study. This scan will look for possible brain inflammation. - Participants will also have an MRI scan. This scan will take pictures of the brain for comparison studies. - Treatment will not be provided as part of this study.
Women are more prone to depression at certain points of the life cycle, although the etiologic and therapeutic implications remain largely unknown1,2. It is reported that pre- and postmenopausal women have a significant difference in response to some antidepressants, within a large clinical trial data set3, 4. A growing number of researches indicate that a woman's hormonal status may influence response to different forms of antidepressant medication. Specifically, younger women appeared to respond better to monoamine oxidase inhibitors (MAOIs) and selective serotonin reuptake inhibitor (SSRIs), whereas men and older women have tended to have relatively better responses to tricyclic antidepressants (TCAs) 1-5. One difference between these classes of antidepressants is that the SSRIs are strongly serotoninergic, whereas TCAs have predominantly noradrenergic effects. One pooled analysis 6 suggests that older women (age ≥ 50) tend to respond poorer to SSRI, while this phenomenen was not observed with venlafaxine. The antidepressive mechanism of venlafaxine that has both noradrenergic and serotonergic effects is superior to SSRIs. As a noradrenergic and serotonergic antidepressant, venlafaxinee has been demonstrated of significant advantages in response and remission rates compared with various SSRIs. As mentioned above, older women tend to have relatively better responses to TCAs which is predominantly noradrenergic antidepressant. Postmenopausal women with depression also would be predicted to respond better to an SSRI if administered along with hormone replacement therapy 6. This could be critical to understanding age difference in antidepressant responses across the life cycle because circulating estrogen levels may modulate central serotoninergic pathways. Therefore, it is presumed that antidepressants which enhance both serotonergic and noradrenergic neurotransmission, as venlafaxine, may be more effective than SSRIs for postmenopausal women with major depressive disorder.
The purpose of the study is to find out what parts of the brain have increased or decreased activity and connectivity in individuals who have bipolar disorder, major depression, or no history of mood disorder. Another purpose of this study is to use MRI images to determine which young adults with major depression may be at greater risk for developing mild or more severe symptoms of mania which suggests a diagnosis of bipolar disorder.
This study is a RCT of transcranial electrical stimulation in depressed patients. Mood, cognitive test performance and biomarkers will be measured during the trial.
Internet-based cognitive behavior therapy (iCBT) has been shown effective for depression in several studies, however the investigators know very little about how the written treatment material should be designed to be effective and at the same time acceptable to the patients. The investigators are not aware of any research that has investigated if slow readers, or persons with difficulty concentrating, can use the standard material or if they would benefit more from using an adapted version. In this study the investigators will assess reading speed and the ability to concentrate in all patients and then randomise them to an internet-based treatment for depression using either a standard material or a condensed one. The condensed material consists of 30000 words and will be available as text files and on audio files. The standard material consists of 60000 words and is only available as text files. Both groups will have the possibility of e-mail contact with a personal therapist during the treatment. Patients will be recruited within Örebro County by referrals and self-referrals. The goal is to recruit between 200 and 300 patients during 2 years. The treatment time will be 10 weeks and all patients will be assessed for depression at an interview with a psychologist. There will also be interviews after treatment and one year after treatment. The most important outcome will be depressive symptoms.
The goals of this study were to a) test whether cognitive behavioral therapy (CBT) is effective in treating depressed Chinese Americans, b) to develop and test the effectiveness of culturally adapt CBT, and c) to test the differential outcomes of the two treatments.
The investigators will investigate in a sham controlled staggered onset design antidepressant effects and safety of deep brain stimulation (DBS) to the superolateral branch of the main medial forebrain bundle (slMFB).
This study will evaluate the efficacy of duloxetine in reducing depressive symptoms, abdominal pain, and other symptoms of Irritable Bowel Syndrome (IRS) in a population of outpatients with Major Depressive Disorder MDD and clinical symptoms of IBS.
Antidepressants generally do not lead to an immediate relief of symptoms. Most people will not see a significant improvement for at least 4 weeks. Studies have generally shown that the full benefits of antidepressant therapy may take as long as 8 to 12 weeks. However, this timeline is variable among individuals.Curcumin is one of the main curcuminoids isolated from this perennial herb. It possesses a variety of pharmacological activities, including anti-inflammatory, antiproliferative, antioxidant, and neuroprotective effects. Curcumin has been found to possess antidepressant action in various animal models of depression. Chronic administration of curcumin has been reported to exert antidepressant-like action in olfactory bulbectomy model of depression in rats. Although the mechanism of the antidepressant effect of curcumin is not fully understood, it is hypothesized that it acts through inhibiting the monoamine oxidase enzyme and modulating the release of serotonin and dopamine.In randomized, double-blind, placebo-controlled study 40 patients will be randomized to receive either 500 mg/day of curcumin or placebo together with antidepressants for 6 weeks.
This research study seeks to provide more insight as to how the microbiome affects or is affected by conditions causing chronic pelvic pain such as Interstitial Cystitis (IC), Chronic Prostatitis/Chronic Pelvic Pain Syndrome (CP/CPPS), Lower Urinary Tract Symptoms (LUTS), or Overactive bladder (OAB). Depression and many chronic pain disorders are often related and are poorly understood, and treatment is often not helpful. The goal of this study is to explain pelvic pain characteristics and causes by studying microbiomes of healthy people compared to people suffering from IC, CP/CPPS, LUTS, OAB, and Major depression.
