Filter by:Deficient cognitive control (CC) is one of the central characteristics of major depression (MD). Hypoactivation of the dorsolateral prefrontal cortex (dlPFC) has been linked with this deficit. Antidepressants and cognitive-behavioral therapies modify CC most-likely as a common mechanism of treatment. Transcranial direct current stimulation (tDCS) is a safe, simple and effective non-invasive method to modulate the cortical excitability. It has been shown, that the activity of the dlPFC can be modulated by transcranial direct current stimulation (tDCS) with polarity-dependent learning-phase specific effects on performance that, when combined with training, can outlast the stimulation. The goal of this randomized, sham-controlled, rater blind clinical trial is to investigate the effect of a tDCS-enhanced CC Training (CCT) on depressive symptom severity and compare the stimulation intensities 1mA, 2mA and sham tDCS. Overall, the study will include 57 participants (n = 19 per group). Each participant will complete 12 training sessions with online sham/ anodal tDCS. As a training task we will use an adaptive version of the paced auditory serial addition task (PASAT). In the PASAT, digits are presented auditive and participants have to add the current digit to the digit they heard before. In the adaptive version the interstimulus-intervals decrease (increase) when four consecutive trials are correct (incorrect). The PASAT is known to elicit frustration. Participants have to exert cognitive control over these emotions to complete the task successfully. Before, during and after the training symptom severity will be assessed. Baseline and post-training performance in the PASAT and in a transfer task (delayed working memory task, DWM) will be measured. To further explore variables that influence the effect of tDCS on depressive symptom severity we will measure brain activity (EEG, NIRS), heart rate, global functioning (GAF), emotion regulation strategies, self-esteem, mood ratings and subjective performance ratings before and after the training and collect genetic factors. Sustainability of the training effects will be measured at a follow-up visit (3 months later).
This study will test whether seven days administration of a serotonin receptor subtype 4 (5HT4) agonist called PF-04995274 has positive effects on cognition, emotional processing and neural activity in unmedicated depressed patients compared to placebo. The study will also include a group of patients randomised to seven days administration of citalopram (20 mg), which is a standard treatment for depression.
This study will test whether seven days adjunctive administration of a serotonin receptor subtype 4 (5HT4) agonist called PF-04995274 has positive effects on emotional processing and non-emotional cognition in medicated, treatment-resistant depressed patients compared to placebo.
Among the major depressive disorder (MDD) patients in the follow-up group, 16 were administered with 50 mg of oral sertralin once daily with placebo, whereas 28 were treated with 100 mg of ketoprofen once daily as adjuvant treatment for MDD. Controls do not take any medicine.
Transcranial magnetic stimulation (rTMS) is an investigational and therapeutic modality that impacts the connection strength between neurons by delivering patterned energy. In response to this patterned energy neurons fire and adapt by changing their connection strengths. This change in connection strengths is believed to be the underlying mechanism whereby this intervention has therapeutic benefit for this intervention in conditions such as depression. The purpose of this study is to test a means of enhancing the effect of rTMS using a medication (cycloserine) that has been shown to augment and stabilize activity dependent neuronal changes. The investigators wish to use the motor system, where the associated muscle response to brain stimulation can be measured, to probe activity dependent changes in connection strength between neurons.
Patients over 65 years old who are exposed to alcohol or benzodiazepines will be recruited through the Fragility Assessment and Addictions Prevention Day Hospital, the Addiction Service and the Geriatric Post-Emergency Department. Toulouse University Hospital. The investigators will study descriptively the frequency of substance use disorder and the frequency of DSM-5 criteria associated with this diagnosis in a population of elderly subjects.
HYPOTHESIS: Pregnenolone administration will be associated with greater reduction in depressive symptom severity than placebo in women with current mMDD. STUDY AIMS: Primary Aim: Determine if pregnenolone is associated with greater reduction in depressive symptom severity than placebo in women with mMDD, as measured by MADRS. Secondary Aims: 1. Determine if pregnenolone is associated with greater reduction in anxiety symptom severity than placebo in women with mMDD. 2. Determine if pregnenolone is associated with greater improvement in cognition than placebo in women with mMDD. 3. Determine if pregnenolone is associated with greater improvement in quality of life than placebo in women with mMDD. 4. Determine if pregnenolone is associated with greater improvement in vasomotor symptoms of menopause than placebo. Mechanistic Aims: 1. Determine whether changes in neurosteroid levels with pregnenolone mediate clinical response. 2. Determine if baseline neurosteroid levels predict pregnenolone response. 3. Determine whether depressive symptoms, anxiety, sleep or vasomotor symptoms improve first. A crossed-lagged panel model will explore serial correlations between changes in outcome measures.
The objective of this study is to compare the rate and extent of absorption of paroxetine hydrochloride 20 mg tablets (test) and Paxil® (reference) administered as 20 mg tablet under fed conditions.
The clinical study is meant to optimize the mobile intervention, to develop a robust implementation plan for the mobile intervention within primary care, and to conduct an effectiveness trial, randomizing 128 participants in order to understand effect on severity of depression and anxiety symptoms, cost-effectiveness, and usability of mobile apps.
Rationale: Depression is a frequent complication after a stroke. In stroke guidelines several recommendations focus on early screening, and treatment off depression after stroke. Introducing clinical practice guidelines into routine daily practice however, is a difficult process. In order to make the recommendations applicable to clinical practice a toolkit was developed (the Post Stroke Depression-toolkit), which provides assessment tools for the early detection of depression after stroke, and a set of interventions in case of a positive screening for (risk on) depressive symptoms. Objective: to investigate the feasibility of the Post Stroke Depression-toolkit in daily practice. Study design: An explanatory mixed-methods, before-and-after study design. Study population: Nurses working on the neurological wards of one university hospital and two general hospitals in the Netherlands were included in the study. Additionally, data were obtained from patient charts.
