Filter by:The specific aims of the study were to explore the effects of the cognitive-oriented intervention program for promoting social support on perceived social supports, depression symptoms, and stress-coping strategies for patients with major depressive disorder in Taiwan.
In this research study the investigators aim to learn more about the therapeutic effects of a newer form of non-invasive transcranial magnetic stimulation (TMS), called theta burst simulation (TBS), on refractory depression in Autism Spectrum Conditions.
The aim of this study is to test if combining the antidepressant Citalopram with Pentoxifylline (PTX), a medicine with anti-inflammatory and phosphodiesterase inhibitory properties, enhanced antidepressant efficacy in adult patients with major depressive disorder (MDD) when compared to Citalopram alone.
The investigators compare the primary and secondary outcome measures using accelerated intermittent theta burst stimulation (aiTBS, 20 sessions active and 20 sessions sham in a counterbalanced crossover design) to treat depressive symptoms with 2 parallel arms of intervention: personalized (stimulation position based on participants' brain networks) vs conventional (stimulation in F3 position of the 10-20 EEG cap) aiTBS.
Major depressive disorder (MDD) is a common, severe, and often life-threatening illness that involves the body, mood, and thoughts. The natural course of MDD tends to worsen without treatment, while people with MDD can lead healthy and productive lives when the illness is effectively treated. Up to 50% of the patients show no response to current available antidepressants.Two major non-invasive brain stimulation (NIBS) tools have been applied for the treatment of psychiatric diseases so far, transcranial magnetic and direct current stimulation (TMS, tDCS). TMS induces a strong magnetic field (magnetic pulses) through the skull into the brain, which generates electrical currents in brain tissue and induces neuronal firing, leading to after-effects, i.e. neuroplasticity, eventually. Neuronal effects of rTMS has been proven to last beyond the actual time of stimulation, enabling altered brain activity for an extended period of time. Adding on rTMS treatment could even give a chance to treat the physical comorbidities and enhance cognitive function in MDD. Nevertheless, underlying neurobiological mechanism of rTMS treatment remains unclear. Reports showed chronic psychosocial stressors are associated with altered frontal-striatal circuitry activation and connectivity. Indeed, aberrant fronto-striatal connectivity and reduced sustain fronto-striatal activation were noticed in MDD patients. However, the specific correlations between fronto-striatal connectivity changes and rTMS treatment outcomes in MDD remain unclear. In this study fMRI will be used to measure the possible correlations between the fronto-striatal circuit activation / connectivity with (1) mood symptoms presentations, (2) neurocognitive measurements, (3) HPA and ANS activities, and (4) immune and metabolic status (cytokines, adipokines and insulin levels) in patients with MDD. Then the possible changes in fronto-striatal FC over a four-week treatment course with 10 Hz rTMS stimulation to left dorsolateral prefrontal cortex will be measured. The FC changes will be tested to find out whether correlate with treatment outcomes, HPA and ANS activity; and immune/metabolic indices changes. We hypothesize that rTMS as an add-on therapy would change the fronto-striatal FC that correlated with mood symptom improvement, neurocognitive measurements, HPA and ANS activity, inflammatory and metabolic homeostasis in patients with MDD.
The purpose of this study is to evaluate the efficacy of NBI-1065845 compared with placebo in participants with MDD on improving symptoms of depression.
A two-center trial to investigate whether or not active stimulation with the Flow FL-100 tDCS device is superior to sham stimulation for the treatment of major depressive disorder when used at home. Participants perform up to 36 tDCS sessions by themselves without supervision during a blinded 10-week phase, and then 30 more sessions during an unblinded open-label phase.
The primary objective of this study is to assess the safety and tolerability of single and multiple oral administered doses of HS-10353 separately in Chinese healthy and major depressive disorder subjects.
This will be a prospective, open-label, single-arm study to determine the safety and feasibility of an intensive treatment of transcranial direct current stimulation (tDCS) for major depressive disorder (MDD). Participants will be age 18-65 with a diagnosis of unipolar MDD. Participants will receive an intensive treatment of tDCS over a 10-day treatment period and complete follow-up assessments at the end of treatment, 1, and 4 weeks post-treatment.
Therapeutic latency, lack of efficacy, and adverse drug reactions are the major concerns in current antidepressant therapies. One-third of the patients with major depressive disorder do not respond to conventional antidepressants that act through the monoaminergic system. To overcome these treatment hurdles, add-on therapy to standard antidepressant drugs may lead to better therapeutic outcomes. The recent discovery of the rapid and sustained antidepressant effect of subanesthetic dose of ketamine led to many extensive clinical and preclinical research in the recent past and has established the possibilities of NMDA receptors as a potential drug target for depression. As repeated doses of ketamine are related to abusive potential and adverse effects, the search for a similar antidepressant agent with a better safety profile is essential. Dextromethorphan has the property of noncompetitively blocking N-methyl-D-aspartate receptors (like ketamine) with additional serotonin transporter and norepinephrine transporter inhibitory action. So, the investigators expect that adding dextromethorphan to selective serotonin reuptake inhibitors (SSRIs) regimen can improve clinical outcomes in major depressive disorder. The literature search found that to date, there is no randomized controlled trial on Dextromethorphan as add-on therapy to first-line antidepressants like SSRIs. So, the present randomized controlled trial has been planned to evaluate the efficacy and safety of add-on dextromethorphan to SSRIs in major depressive disorder.
