Filter by:This study evaluates the effectiveness of a Positive Psychology intervention, that is focused on increasing the positive emotions and strengths of human beings. It is compared to the effectiveness of an online treatment with the change of the same participants before and after receiving the treatment accompanied by a chat support service vs. the treatment solely. The changes are being assessed through worldwide validated measures such as psychometrics.
This study characterized the impact of respiratory-gated transcutaneous vagus nerve stimulation (tVNS) on the modulation of the stress response circuitry, vagal tone and depressed mood in patients with major depressive disorder (MDD). Twenty premenopausal women with recurrent MDD in an active episode were recruited into a single-blind cross-over study that included two functional MRI visits within a one week period with simultaneous mood and physiological assessments. Randomization to exhalatory- or inhalatory-gated tVNS was performed to control for order effects. The study hypothesis was that exhalatory-gated tVNS would have a significantly greater impact on the regulation of brain activity in stress response circuitry, vagal tone and depressed mood in MDD patients compared to inhalation-gated tVNS.
This study will examine whether semaglutide may improve cognitive function in individuals with major depressive disorder (MDD).
The purpose of the study is to describe the pharmacological and non-pharmacological treatment utilization pathways in Italian routine clinical practice of participants with Major Depressive Disorder (MDD) and active suicidal ideation with intent.
Joiner's interpersonal theory of suicide postulates that the wish of death comes from feelings of perceived burdensomeness and thwarted belongingness. But, only people who have acquired the capability to kill themselves will attempt suicide. The acquired capability refers to a reduction of fear to death, and a higher pain tolerance. Indeed, to commit suicide involves to endure pain during the act. Thus, higher pain tolerance seems to be a necessary feature for suicidal act. Past studies have shown higher pain threshold and tolerance in suicidal patients, whatever the stimulus was (electric, thermic or mechanical), compared to patients without suicide history. Moreover, Caceda and colleagues demonstrated higher pain threshold in recent suicide attempters (suicidal act within 72h) compared with depressed patients. Five days after the initial evaluation, pain threshold of recent suicide attempters decreased to be similar to depressed patients with suicidal ideation. Therefore, it may exist a specific state during which the pain tolerance is increased. During this "hypoalgesic state" patients with suicidal ideation could attempt suicide to get relief from suffering. However, little is known about the specific mechanisms that are responsible for the higher pain threshold and tolerance in suicide attempters. Pain is a dynamic system that results from excitatory and inhibitory messages. The modification of one of these mechanisms could explain the higher tolerance in recent suicide attempters. Three of them are of particular interest: 1. The conditioned pain modulation (CPM) is a modulatory pain mechanism. CPM works through descending pathway that reaches the spinal cord and modulates pain processing from the first nociceptive synapse.In recent suicidal patients, an increase of the CPM could explain higher pain tolerance. 2. The "wind-up" mechanism is defined as the highest excitability of the second order nerve. Even if the stimulus remains stable, pain continuously raises. In recent suicide attempters, a reduction of this mechanism could explain higher pain tolerance. 3. The threshold of Aδ and C nociceptors. If a nociceptive fiber is less excitable than the other, it would explain higher pain threshold.
The purpose of the study is to evaluate the effect of seltorexant, compared to placebo, as an add-on medication to an antidepressant, on next-day driving performance as assessed by the mean difference of standard deviation of lateral position (SDLP) from an on-road driving test in participants with major depressive disorder (MDD).
Studies have shown that admission to hospital during a coronavirus epidemic is associated with increased levels of anxiety, depression and panic disorder. During the SARS-CoV-2 pandemic in North London the Royal Free Hospital admitted over 500 patients with Covid-19. As part of the standard of care, these patients are screened at 8 weeks post discharge for signs of anxiety and depression. The Feeling Good app is a NHS approved digital application which utilises applied relaxation, mindfulness based cognitive therapy and positive visualisation through audio tracks for the treatment of anxiety and depression. This is a naturalistic cohort study aimed to track the post illness psychological symptoms of those who have been admitted with Covid-19 to the Royal Free hospital up to 5-7 months after discharge. The study population is those who are exhibiting anxiety or depressive symptoms as measure by the PHQ-2 or TSQ questionnaires. All those with symptoms will be offered free access to a NHS approved app for anxiety and depression, and followed up for 3 months after recruitment to track changes to their symptoms.
The purpose of this study is to compare the efficacy of vortioxetine versus desvenlafaxine after 8 weeks of treatment in patients that have tried one available treatment without getting the full benefit
This study will identify the sex-dependent impact of expiratory-gated transcutaneous vagus nerve stimulation (tVNS) on the modulation of the stress response circuitry and associated physiology in major depressive disorder (MDD). We will evaluate a sample of 80 adults with recurrent MDD randomized to receive active or sham expiratory-gated tVNS during a functional magnetic resonance imaging (fMRI) session, with simultaneous mood and physiological assessments. We hypothesize that expiratory-gated tVNS will effectively modulate, in a sex-dependent manner, specific brainstem-cortical pathways of the stress circuitry and attenuate physiological deficits in MDD.
This project seeks to know the prevalence of mental health problems among undergraduate students, through internationally and nationally validated screening instruments. The project also aims to understand better the associated factors contributing to the mental health problems of this population. Through the critical analysis of the results, our proposal aims to establish the prevalence of anxiety, depression, suicidality and substance use, and the association with socioeconomic features, academic stress, sense of belonging to the university, interpersonal relationships, and sleep habits among other factors. Once finalized the study, the results obtained will be disseminated to the university community and published in peer-reviewed journals. The results will help the university authorities to design and implement measures to prevent mental health problems in this community.
