Active clinical trials for "Depressive Disorder"

In the past, there were studies on relationship between insomnia and depression, and those studies found that depression can be the result of untreated insomnia. Mostly insomnia precedes depression, and is a marker for recurrence of depression. Research suggests that insomnia may cause depression by changing the emotional response. In this study, investigators will establish the national online cognitive behavioral therapy for insomnia (e-aid Cognitive Behavioral Therapy for Insomnia, eCBTI ) tools, and online health education on sleep (e-aid Sleep Hygiene Education, eSHE ) tools for controls. Investigators will be testing whether eCBTI can reduce the incidence of depression in patients with sleep disorders, increasing remission rate of depression, and a corresponding reduction in suicidal ideas, compared with eSHE control groups.

In this proposed study, the investigators will evaluate the effects of fish oil add-on in treatment of major depressive disorder(MDD).

Anxiety and depression are currently among the ten most important public health concerns, and in recent years, have reached epidemic proportions. Anxiety is recognized as the main risk factor for many diseases including cardiovascular, metabolic and neuropsychiatric disorders. Current anxiolytic medications have a relatively low success rate (~50%) and are associated with many deleterious side-effects. The investigators aim to investigate the efficacy, safety, and tolerability of a novel herbal treatment on anxiety and depression symptoms in a 6-week double-blind randomized trial.

This is a randomized controlled study assessing the effect of pre-emptive hyperventilation on ECT seizure duration, cerebral desaturation and remission of depressive symptoms in patients with Major Depressive Disorder. Comparison of etomidate and ketamine on remission of depressive symptoms with and without pre-emptive hyperventilation will also be studied.

Repetitive transcranial magnetic stimulation (rTMS) is an emerging treatment for medically refractory major depressive disorder (MDD), and involves direct stimulation of cortical neurons using externally applied, powerful, focused magnetic field pulses. rTMS consistently achieves response rates of 50-55% and remission rates of 30-35% in medically refractory MDD patients. However, the vast majority of studies have focused its use in outpatient samples. This study will address whether accelerated rTMS (intermittent Theta Burst Stimulation (iTBS)) can speed up the response rate and shorten length of stay in hospital for inpatients, and which biological traits may predict response.

The objective of this study was to compare the therapeutic effects of Auricular Concha Electro-acupuncture and Citalopram on patients with major depressive disorder (MDD).

The habenula (Hb) is an ancient structure, located at the center of the dorsal diencephalic conduction system, a pathway involved in linking forebrain to midbrain regions. An increasing number of studies indicated that the lateral habeluna (LHb) is overactivity during depressive behaviors in rats, where it could drive the changes in midbrain monoamine neurotransmitter linked to depression. However, the efficiency and mechanism of deep brain stimulation (DBS) of the LHb and/or its major afferent bundle (i.e., stria medullaris thalami) could treat treatment-resistant major depression (TRD) is still unclear. This research will investigate the effectiveness and mechanism of bilateral MRI Compatible and Long-term LFP Recordable DBS to habenula and/or its major afferent bundle for treatment TRD patients.

Post-stroke depression (PSD) is one of the most common complications after stroke, with a high prevalence. PSD can affect prognosis and rehabilitation of stroke, increase risks of mortality and suicide, and escalate the economic burden on individuals and society. Studies have shown that transcranial alternating current stimulation (tACS) can also be used to treat depression, insomnia and anxiety. So far, this stimulator has been approved by FDA. However, there have not been any reports on the use of tACS in the treatment of depression and PSD in China. In this trial, the efficacy and safety of the tACS will be assessed with the rigor methodology manner.

Study of individualized accurate targeting rTMS intervention on motivational anhedonia of treatment resistant depression and brain network mechanism

This is a pilot interventional study to investigate the acceptability, tolerability, and side effect profile for varying numbers of treatment sessions/day of a new rTMS treatment in adolescents with treatment-resistant depression (TRD). Conventional rTMS has been limited to sinusoidal biphasic electromagnetic pulses. In contrast, the First Dawn rTMS system by NeuroQore can sustain a repetitive linear asymmetric pulse. In addition, identification of rTMS treatment sites in adolescents with TRD most often relies on anatomic landmarks, but the First Dawn rTMS system utilizes personal fMRI data in a novel algorithm to determine where to apply the rTMS in each patient. Based on adult data in healthy volunteers and patients with TRD, the investigators propose that the First Dawn rTMS system will be acceptable and well-tolerated by adolescents and will have minimal side effects. Please see https://clinicaltrials.gov/ct2/show/NCT02667041 for details on the completed pilot study in adults. The investigators aim to investigate acceptability, tolerability, and side effects in groups of patients receiving treatment in numbers of sessions/day that are gradually accelerated over the course of the study. Results will be used to inform the development of a randomized controlled trial.
