Active clinical trials for "Mental Disorders"

The purpose of this study is to identify the variations in gut microbiota compositions between two subtypes of major depressive disorder.

This application proposes OnTrackNY as a regional scientific hub for the Early Psychosis Intervention Network (EPINET) program as part of the National Institute of Mental Health (NIMH)'s creation of a national learning health care system (LHS) for early psychosis care. OnTrackNY has grown into a 22-site network, under the leadership of Lisa Dixon, MD, MPH. Created and supported by the New York State's Office of Mental Health (OMH), OnTrackNY is a nationally recognized model providing coordinated specialty care (CSC) for adolescents and young adults within two years of the onset of non-affective psychosis. OMH regulates and licenses all mental health programs in New York and is a direct-services provider via state-operated programs statewide. This makes OMH an ideal partner for establishing a statewide learning health care system for early psychosis care. Further, OnTrackNY's administration, OnTrackCentral, operates within the OMH-supported Center for Practice Innovations at Columbia Psychiatry. In this model, OnTrackCentral serves as the hub and the 22 OnTrackNY programs serve as the spokes. Since 2014, the still-growing OnTrackNY network has served over 1,600 individuals. From its inception, OnTrackNY has aimed to deliver high-quality, data-driven, accountable and culturally competent care consistent with an LHS. As a condition of funding, all OnTrackNY providers follow established protocols that require submission of patient- and site-level standard measures of early psychosis clinical features, services, and treatment outcomes. The proposed EPINET regional hub, the OnTrackNY LHS, will emphasize and enhance two critical foundational components - Aim 1: proactively engage stakeholders to optimize understanding of key problems and their solutions at every LHS phase; and Aim 2: develop data systems with enhanced standardized data collection, including post-discharge data and linkages to external data systems, and enhancing data analytics that will allow for client-level treatment planning and prospective analytics, delivering real time, dynamic and actionable information to stakeholders. These LHS components do not follow in a stepwise sequence but instead operate in parallel and interact to facilitate and enhance quality improvement processes. This backbone will support the development of practice-based research.

This study aims to investigate the neural correlates (structural changes, functional connectivity, and structural connectivity of brain structures in prefrontal cortex and basal ganglia) of impulsivity by measuring structures and the blood-oxygen-level-dependent signal of brain in response to impulsive tasks and task-free using functional Magnetic Resonance Image method among healthy controls, patient with prodromal PD (iRBD), and patients with PD.

Patients with Psychotic disorders (Schizophrenia, Bipolar disorder and Schizoaffective disorder) often suffer from significant cognitive impairments, however how these develop and change over time before and after the first psychotic break is unclear. While there are data by several groups, showing that many future patients have significant cognitive impairments years before the onset of psychosis, many future patients seem to be doing well before the manifestation of psychosis, and decline steeply in functioning after their first psychotic episode. Hence the timing of the onset of cognitive impairment in patients with psychotic disorders requires further exploration. The current study will investigate the timing of cognitive impairment by using IQ tests before and after the first psychotic break

Several studies agree on the increase in suicide attempts in children over the past 15 years. This trend has been aggravated by the COVID 19 pandemic. It is recognized that suicide attempts are mostly encountered in individuals with a psychiatric disorder. Serious suicide attempts, which probably better reflect the risk of completed suicide, are very poorly known and have been very little explored. They could be related to more specific and earlier psychiatric disorders or even concern children with developmental particularities that are insufficiently defined to fall under a categorical diagnosis, but which could be better understood with dimensional measurements. Better characterizing them would seem quite important given their high lethality. Indeed, a high lethality is found for half of the suicide attempts in children fewer than 12, contrasting with a moderate or low intentionality ; in children, the means used are often more violent and more lethal than in adolescents (over 12 years old): hanging, firearm, etc. The Necker-Enfants Malades hospital has a pediatric neurosurgery department as well as a specialized multidisciplinary team to care for polytraumatized children in a regional "Trauma Center" type structure. As a result, most children and adolescents in Ile-de-France who have made a violent suicide attempt are sent to the Necker hospital. Once medico-surgically stabilized, these children and adolescents are assessed by the hospital's child psychiatry team. This regional recruitment makes it possible to have an epidemiological representativeness. From this population, the investigative team proposes to better characterize the developmental profile and psychiatric disorders of children who have made a serious suicide attempt. The study also proposes to examine in detail the psycho-emotional development as well as the psychopathological characteristics of these children in order to shed light on these early and lethal acting out. The investigative team proposes in particular to use dimensional evaluations to analyze behavioral traits in more detail. To the knowledge of the child psychiatry department of the Necker Enfants Malades hospital, there is no such study to date.

Psychosis is a severe mental health problem. Symptoms of psychosis include hallucinations (e.g. hearing voices that others cannot hear) and delusions (unusual, often troubling beliefs). People who experience psychosis often have times when their symptoms are relatively stable. At other times, their symptoms may increase and become much more problematic (a 'relapse'). Helping people with psychosis to stay well (preventing relapses) is an important and time-consuming challenge for mental health services. Smartphones and other digital technologies are now widespread. This offers a solution to help tackle the overwhelming demand on services and to enable people with psychosis to access mental health support when they need it most (e.g. when relapsing). Research shows that people with psychosis are often willing to report their symptoms using a smartphone app. Apps like this can alert health professionals when someone needs extra support, but can be burdensome to use long-term. The investigators want to make a system that is less burdensome and is personalised to users' needs and experiences (a 'complex digital remote monitoring system'). Recent research shows that information gathered routinely by individuals' smartphones (e.g. GPS, step count) might help predict relapses of psychosis. The investigators want to use this method in a complex digital remote monitoring system. First, the investigators need to know what people with psychosis and mental health staff think about this idea. The investigators will interview around sixty adults with psychosis and around forty staff, recruited from UK mental health services (Manchester, Glasgow, Edinburgh, Cardiff, London, Sussex). These one-off, audio-recorded interviews will last up to 60 minutes. The interviewer will ask about participants' views on complex digital remote monitoring. The investigators will then systematically analyse the interviews. Findings will inform the design of the investigators' own complex digital remote monitoring system and future digital tools designed by other researchers. NIHR and Wellcome are funding this study.

This study is the first part of a larger project called "Virtual Reality (VR) as a facilitator for participation in society among persons with mental health/substance use disorders" in which aims to explore,develop and evaluate a VR-based paradigm that facilitates social participation and promotes social recovery of individuals with mental health and/or substance use disorders (MHD/SUD). The overall project comprises three work packages: an exploration study, a development study, and an evaluation study. This study will make up work package 1. The primary aim of this study (WP1) is to explore facilitators and barriers for participation in society among person with MHD/SUD, and to provide an understanding of mechanisms of social participation and social cohesion among persons with MHD/ SUD that may be affected by VR-based interventions. The investigators will derive a socio-emotional learning domain to facilitate key interpersonal and social processes among persons with MHD/SUD in VR-based interventions. To achieve the purpose of this study, the invistigators conduct 10 indepth interviews with service-user with MHD/SUD, 2 focus group interviews with 14 service-providers and an interview-survey with 100 service users. This gives the investigators the possibility to explore facilitators and barriers for social participation as experienced as by individuals with MHD/SUD and identify key interpersonal and social processes suitable to be addressed by tailored VR based interventions.

REM sleep behavior disorder is a novel and distinct parasomnia characterized by recurrent dream enactment behaviors (DEBs) and REM sleep without atonia (RSWA) during polysomnographic assessment, with a male predominance and typical onset age at early 60's. The majority of patients with idiopathic RBD (iRBD) will eventually develop α-synucleinopathy, for instance Parkinson's disease (PD). Thus, iRBD has been considered as a highly specific precursor of α-synucleinopathy-related neurodegeneration. Recently, increasing studies have found that some participants present with only RSWA or DEBs (but without sufficient RSWA), which does not meet the diagnostic criteria for RBD. It has been suggested that these participants with subclinical features (either DEBs or RSWA) might represent a condition known as prodromal RBD. Several emerging evidence, including our own study, have implied a link between isolated RSWA (RSWA without DEBs) and markers of α-synucleinopathy-related neurodegeneration. However, it is still unclear whether the other condition related to RBD, i.e. recurrent DEBs but without sufficient RSWA, is related to a certain degree of α-synucleinopathy. In this regard, the novel concept of recurrent DEBs but without sufficient RSWA, also termed as prodromal/isolated RBD by some researchers, requires validation by further evidence in terms of clinical feature and neurodegenerative prodromal markers perspectives.
