Filter by:This experiment intends to explore the differences among various types of depression, as well as the differences between healthy subjects and depressed patients, and find possible biological markers from the severity of symptoms, social function and cognitive function of depressed patients, combined with EEG characteristics, biological test indicators (blood, faeces, hair, etc.) and functional magnetic resonance imaging data. To explore the changes in clinical symptoms, cognitive and social functions, and biological indicators of various types of patients before and after treatment, to provide references for the prognosis of various types, and to predict the future development of the disease according to the baseline indicators of patients; According to the above aspects, this experiment can follow up the patients with depression, track their disease development, and study the potential biological changes in the early stage of the disease, which has the potential to reveal the pathogenesis and provide guidance for the early diagnosis and intervention of depression.
The purpose of this study is to establish how personalization of repetitive transcranial magnetic stimulation (rTMS) can change markers of brain activity and improve treatment response. To do this, all participants will receive the same active form of treatments, but some of the participants in this study will receive intermittent theta burst stimulation (iTBS) rTMS treatment with standard forms of targeting and intensity, and others will receive iTBS rTMS treatment using personalized magnetic resonance imaging (MRI) and electric field (E-field) modeling measures.
This is a single-arm, open-label interventional study of psilocybin-assisted interpersonal therapy for treatment resistant depression. 20 participants will be recruited to take part in this 8-week intervention that involves 8 sessions of psychotherapy and 2 doses of psilocybin.
The present multiple baseline single case trial will study the efficacy and acceptability of the "Unified Protocol for the Transdiagnostic Treatment of Emotional Disorders" in the treatment of emotional symptomatology and/or emotional disorders in a sample of patients with Post Covid-19 condition.
Previous research by Mental Health Research Network (MHRN) investigators and others demonstrates that online messaging and other telehealth technologies can effectively and efficiently address premature discontinuation of depression treatment. These interventions, however, have focused on adherence after treatment initiation and have been tested primarily in non-Hispanic white populations. Less is known about the acceptability and effectiveness of different communication modalities (online messaging, mailed letters, telephone) among racial and ethnic minority populations. Implementation of electronic-Health (eHealth) technologies must take care not to exacerbate health disparities. This clinical trial involves a pilot trial to evaluate a population-based outreach program to improve rates of depression treatment initiation among traditionally underserved racial and ethnic groups. This pilot work intends to inform a subsequent full-scale pragmatic trial to examine impact on health disparities.
Major depressive disorder (MDD) is the world's leading cause of disability according to the World Health Organization. MDD is highly recurrent, even if clinical remission is reached after successful treatment. In fact, the enormous burden of disability, mortality and financial costs is due to the recurrent and chronic nature of MDD. The reliable prediction of the recurrence of major depressive episodes (MDEs) based on a prognostic model that is informed by biological, neurophysiological or neuroimaging data would be valuable and lifesaving for many. However, such models are still lacking. Several lines of evidence point to abnormal prefrontal control over limbic emotion processing areas in MDD owing to diminished prefrontal excitability that seems to persist during MDD remission (rMDD). Prefrontal excitability in rMDD may thus be a trait marker of MDD and may potentially be indicative of disease recurrence. Yet, research investigating the potential utility of prefrontal excitability for predicting the recurrence of MDEs is lacking. Cortical excitability can be investigated using transcranial magnetic stimulation (TMS); however, human studies have mostly probed cortical excitability of the motor cortex, a brain region not considered to be central in the neuropathology of MDD. Hence, knowledge of the effect of TMS on prefrontal excitability is limited. Moreover, whether immediate prefrontal modulation by TMS can predict the recurrence of MDEs in fully remitted MDD patients remains to be investigated. Thus, there is a need for research that aims to quantify the direct and immediate aftereffects of TMS on prefrontal function. Most importantly, with regard to precision medicine, there is a need for research that explores the utility of immediate prefrontal reactivity to TMS for predicting MDE recurrence. Here, the investigators propose a research program that will exploit the combination of functional near-infrared spectroscopy (fNIRS) with brain stimulation. Concurrent theta-burst stimulation (TBS)/fNIRS measurements will allow us to systematically investigate stimulation-induced modulation of blood oxygenation as a proxy for induced brain activity changes (TBS is a modern form of patterned TMS). The findings from this study will (1) elucidate the immediate effects of excitatory and inhibitory brain stimulation on prefrontal activity in rMDD and controls and (2) validate the potential utility of stimulation-induced brain modulation for the prediction of MDE recurrence.
Measurement-based care (MBC) is an evidence-based practice that incorporates routine outcome assessment using validated rating scales to guide collaborative clinical decision-making. Although MBC results in improved outcomes for patients with major depressive disorder (MDD), there are barriers to its broad implementation in clinical settings. The use of "enhanced" MBC (eMBC), with mobile apps that allow patients to track outcomes and engage in self-management via WeChat, may address some of these barriers. This study intends to compare differences of efficacy between the implementation with eMBC using WeChat and the standard MBC implementation using paper-pencil assessments at the clinic, for both implementation and clinical outcomes.
The study will compare the efficacy of intermittent Theta Burst Stimulation (iTBS) with DLPFC-pgACC personalized target for major depressive disorder (MDD) and explore possible brain network mechanisms. The stimulated targets will be located by magnetic resonance imaging (MRI) based on functional MRI based on functional connectivity respectively. This study aims to identify that functional connectivity targeted iTBS protocols on DLPFC-pgACC personalized target have a better antidepressant efficacy compared the sham group and certify that pgACC is an effective potential effector target.
Major depressive disorder (MDD) is characterized by a cognitive triad of negative beliefs about oneself, the future and the world. For example, depressed patients hold persistently negative expectations about the future, despite contradictory evidence, and these strong negative beliefs are thought to play an important role in the maintenance of depressive symptoms and potentially in treatment resistance. Indeed, one out of three patients with major depressive disorder does not respond to conventional, monoaminergic treatments, which has led to the concept of treatment resistant depression (TRD). It is unknown how the brain encodes the strong negative beliefs that are insensitive to positive disconfirming information in TRD patients, and how these neural underpinnings of maladaptive belief updating are altered by antidepressant treatment. The principal objective of this study is to gain insight into the brain mechanisms of belief updating about the future in TRD patients before and after starting ketamine treatment. The results of this study are expected to provide a better understanding of the neurocognitive mechanisms of belief-updating in depressed patients, and how these mechanisms contribute to clinical improvement following ketamine antidepressant treatment.
Participants were assigned to intervention and control groups according to the randomization list previously prepared by the researchers. All participants were first informed about the study and their informed consent was obtained. Participant Information Form, Geriatric Anxiety Scale, Psychological Well-Being Scale, and Geriatric Depression Scale were filled out by all participants. The elderly in the intervention group were divided into 5 groups of 10 and a time was determined for the session in cooperation with the participants in each subgroup. A 60-minute therapy session was administered by the occupational expert. The applications were carried out in a total of 7 sessions as a daily session. The control group was not subjected to any application. Geriatric Anxiety Scale, Psychological Well-Being Scale, and Geriatric Depression Scale were refilled for the second time in all elderly on the 7th day after the application.
