Filter by:Major Depressive Disorder (MDD) is a serious mental illness and public health problem that poses threat to both physical and mental health. According to statistics from WHO, it is estimated that more than 350 million people worldwide suffer from depression, with a prevalence rate of 2.1% in China, which is approximately 30 million people. At present, due to the lack of neurobiological markers for screening and diagnosing depression, the identification and diagnosis of MDD are based on the judgment of professional doctors, and the treatment mostly relies on clinical symptoms. In terms of treatment, medication remains the main stream for MDD. Although current methods have certain therapeutic effects, patients still suffer from various side effects and poor cognitive function.In current clinical practice, relying purely on symptomatic diagnosis and treatment is difficult to meet the needs of clinical practice, so there is an urgent need to search for neurobiological markers in depression and develop targeted non-invasive intervention technologies. This study aims to combine advanced brain imaging technology, digital twin-brain models, multi-source information decoding technology, integrated detection and intervention technology. The target is to create two new types of non-invasive BCI systems that can regulate emotions. One is a intervention BCI system for MDD that is suitable for hospital settings with the purpose of precise physical stimulation, and the other one is an ecological BCI system that regulate emotions and intervene with depression which is suitable for both hospital settings and future family environments. This study will collect a comprehensive collection of physiological and biochemical indicators from patients with depression and from healthy control groups, as well as multimodal information such as head surface electroencephalography, MRI, and eye movements under different brain states, to personalize the available BCI information of depression related brain regions, circuits, and networks. The study also tries to explore emotional-interactive games that can intervene with depression and build a game data base that is dedicated to MDD. Other goals include designing and establishing two new types of emotional regulation systems, which are precise external physical stimulation intervention and ecological intervention, constructing a BCI regulation system, and conducting application verification to evaluate the regulation effect.
This is a multicenter, randomized, double-blind, placebo-controlled study in pediatric patients who are experiencing major depressive episodes (MDEs) associated with a primary diagnosis of bipolar I or bipolar II disorder as confirmed by Kiddie Schedule for Affective Disorders and Schizophrenia for School-Age Children-Present and Lifetime Version (K-SADS-PL), according to criteria of the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM 5).
The purpose of this trial is to determine if intermittent theta-burst stimulation (iTBS) can reduce the symptoms of depression in treatment-resistant bipolar disorder. To do this, some of the participants in this study will receive treatment with active iTBS stimulation, while others will receive sham iTBS stimulation. Participants will come for 30 days of either active iTBS or sham iTBS, with a 6-week follow-up period. Symptoms of depression (for determining treatment efficacy) and mania (for determining treatment safety) will be assessed using the 17-item Hamilton Rating Scale for Depression (HRSD-17) and the Young Mania Rating Scale (YMRS) every five treatments during the treatment course, and at 1 week and 6 week after treatment completion.
This is an observational (non-interventional) study, carried out in an outpatient setting, which involves a blood sampling. The primary objective of this study is to confirm the association between the EDIT-B® editing signature and early unipolar or bipolar differentiation. Results of this research may provide an aid to early diagnosis and guide clinical practice towards individualized treatment.
This is an observational (non-interventional) prospective study, carried out in drug-naïve outpatients who start a treatment with escitalopram, fluoxetine, sertraline or quetiapine. Five blood samples are collected (i.e. before initiating the drug, and then after 1, 2, 4 and 8 weeks of treatment). It does not affect the choice or the treatment dose. The primary objective of this study is to measure the association between the EDIT-B® editing signature and response to pharmacological treatment in drug-naïve patients. Results of this research could provide an aid to early diagnosis, optimize pharmacological treatment and guide clinical practice towards individualized treatment.
The purpose of this study is to o evaluate the antidepressant efficacy of the PEA in Bipolar Depression and the association between antidepressant response with endogenous cannabinoids and cytokine levels
This is an open-label study, in which all participants receives an active treatment with repetitive transcranial magnetic stimulation (rTMS) according to clinical protocol. The aim with this pilotstudy is to investigate the feasibility to perform a trial of low-frequency rTMS on treatment-resistant depression in adolescents. The study includes adolescents 13-19 years old, with average to severe depression.
This is a 2x2, within-subjects, cross-over trial to test the anti-depressant effects of acute exercise in 20 participants with bipolar depression. Participants will complete four experimental sessions, two with an exercise challenge and two with a resting control condition in a counterbalanced order. Participants will receive either 800mg of ibuprofen or placebo before exercise or rest in order to test whether blocking the inflammatory response to exercise interferes with the neural and psychological effects of exercise.
Major Depression is often resistant to treatment, and all of the currently marketed anti-depressants can cause significant side effects and may precipitate mania. The aim of this proposal is to perform a proof-of-concept RCT testing Palmitoylethanolamide (PEA) as a treatment for unipolar or bipolar depression, randomizing 100 patients to 6-week treatment with PEA 1200 mg/d or matching placebo. There are several rationales for this study: (A) PEA acts at the peroxisome proliferator-activated receptor-alpha (PPAR-α), stimulating Allo biosynthesis. Allo is an endogenous, positive allosteric modulator of GABA-A receptors in glutamatergic neurons, including cortical and hippocampal pyramidal glutamatergic neurons and may be one of the endogenous regulators of depression and anxiety. (B) Sage Therapeutics has developed Allo which is FDA approved to treat post-partum depression, and is testing a molecular modification which can be administered orally for post-partum depression and unipolar depression, with mixed efficacy results. Pregnenolone, a precursor of neurosteroids, has also been reported to improve bipolar depression. Based on animal models, PEA increases Allo synthesis in areas of the brain thought to be involved in anxiety and depression. It may also favor the biosynthesis of sulfated forms of Allo and congeners that inhibit tonic rather than phasic NMDA-mediated excitatory neurotransmission. Showing that PEA-induced selective inhibition of tonic NMDA neurotransmission improves depression might enable development of steroid-based NMDA-inhibitor therapeutics. In addition, PEA-induced Allo upregulation potentiates GABA-A receptor-mediated inhibition. The NMDA and the GABAergic mechanisms may act in concert to improve behavioral outcomes. Since PEA increases Allo in the brain where it is endogenously formed, it might be more effective compared with exogenous administration, which is not site specific. There is evidence of a role of inflammation in depression; PEA has potent immunoregulatory and anti-inflammatory effects by directly activating PPAR-α, which has a protective role against neuroinflammation by inhibiting the signaling mediated by toll-like receptor 4.There is one published study which shows that PEA has an antidepressant effect in unipolar depression, 58 patients were randomized to receive 1200 mg/d of PEA or placebo added-on to citalopram, showing clinical improvements in patients receiving PEA.
Bipolar disorder (BD) affects between 1-3% of the world's population. People with BD experience episodes of mania or hypomania and in most cases, they experience periods of depression which can cause difficulties in daily life. Psychological therapies for people experiencing depression without mania or hypomania are widely available, but there is little research into how effective these therapies are for people with BD. Behavioral activation therapy (BA) is based on behavioral theory and has been proven to be an effective treatment for unipolar depression. It helps people re-establish healthier activity patterns and sleep regulation, especially in BD for mood stabilization. BA is theoretically and clinically well matched to the treatment of bipolar depression, but there is still very little research into offering BA to people with BD. The first aim of the current research is to implement BA for people with depression in Bipolar Disorder and study if it is feasible for this patient group. The second aim is to do a pilot study on the effectiveness of the treatment for this patient group. The research will be implemented with people seeking treatment at the specialized service for bipolar disorder at Landspítali University Hospital in Iceland. The participants will receive treatment as usual and the BA will be adjunctive. At least ten people, that are currently experiencing Bipolar Depression and are willing to take part, will receive up to 20 individual therapy sessions of BA that have been adapted for Bipolar Depression (BA-BD), and will complete regular questionnaires and interviews. The study will be a replication study to validate the previous study's findings by Kim, W. et al., 2022 in another setting.
