Filter by:Parkinson's disease (PD) is characterized by many non-motor symptoms that occur several years before the diagnosis, in particular idiopathic REM behavior disorder (iRBD), which is associated with autonomic impairment. The purpose of this study is to investigate the effect of treatment with the selective post-synaptic a1-adrenergic blocker terazosin on 123I-MIBG myocardial uptake in a population of subjects with defined pre-motor PD risks (i.e. hyposmia and RBD) and abnormal baseline 123I-MIBG uptake, with or without 123I-Ioflupane uptake abnormality or PD motor symptoms. Scintigraphic changes will be correlated to motor and non-motor severity of PD, measured by validated clinical scales and cardiac autonomic function tests.
France has been put on a lockdown for 8 weeks to prevent the spread of the COVID-19 virus between 17/03/2020 and 11/05/2020. During this lockdown, which is likely to have psychopathological repercussions on the population, the public authorities and the media informed the population about the number of deaths occurring each day. While the functioning of autobiographical memory following traumatic events remains a debate in the literature, the impact of the daily announcement of mass deaths on the memory system in the general population and the relationship between long-term memory and delusional thinking in certain psychopathologies have yet to be explored in the literature. The investigators wish to demonstrate that self-reported recall of recorded deaths may represent this distortion of perception, symptomatic of these pathologies by an on-line questionnaire.
The main objective of this multicenter cohort study is to determine the degree of COVID19 infection immunization of a population of psychiatric patients. The secondary objective of this cohort follow-up is to: 1. Clinically characterize COVID patients who are positive for serological testing 2. Assess the socio-demographic, clinical and psychotropic determinants of a COVID diagnosis 3. Immunologically characterize COVID patients who are positive for serological testing 4. Exploring the links between susceptibility to COVID19 and erythrocytic blood groups
Engagement with clinical services for youth with early psychosis represents a significant challenge, with up to 40% of patients dropping out of treatment in the first year. This has been linked to worse illness outcomes and represents a significant barrier to recovery for these patients. This study aims to evaluate the efficacy of short message service (SMS) as a means of improving clinical engagement in early-episode psychosis populations by bridging contact between appointments with weekly check-ins/reminders. These weekly check-ins during the first year of treatment will serve as an additional opportunity to reach out to patients and give them a chance to do the same with their care teams, with patient responses triggering clinician follow-up if necessary.
The purpose of this study is to evaluate the impact of an antipsychotic medication decision aid and interpersonal and cognitive factors, such as attachment style and motivation, on emerging adults' ability to engage in shared decision making regarding their medications.
Patients with Parkinson's disease (PD) sometimes experience symptoms affecting their movement, such as slowness, tremor, stiffness, and balance or walking problems. Many patients also have other symptoms not related to movement, called non-motor symptoms, which may affect one's mood or emotions, memory or thinking, or cause one to see or hear things that aren't real (hallucinations) or believe things that aren't true (delusions). Hallucinations or delusions, together called psychosis, occur in up to 60% of PD patients at some point in time. Parkinson's disease psychosis can sometimes be associated with decreased quality of life, increased nursing home placement, increased rate of death, and greater caregiver burden. There are approximately 50,000 Veterans with Parkinson's disease receiving care in the VA, and up to 30,000 (60%) of them will experience psychosis at some point in time. Quetiapine is an antipsychotic drug approved by the Food and Drug Administration (FDA) that is the most commonly used medication to treat PD psychosis, but more studies are needed to determine if it works for this condition and is also well tolerated and safe. Pimavanserin is a newer antipsychotic drug approved by the Food and Drug Administration (FDA) specifically to treat PD psychosis, but more studies are needed to determine if it works and its safety. The purpose of this research is to gather additional information on the safety and effectiveness of both Quetiapine and Pimavanserin. By doing this study, the investigators hope to learn which of these medications is the most effective course of treatment for people with PD psychosis.
Five collaborating sites in France will study the broad spectrum of schizophrenia in children and adolescents. Patients will be studied with diagnostic interviews, developmental histories, dimensional clinical ratings, comprehensive cognitive assessments, neuroimaging and DNA (copy number variant) analyses (in families and patients who agree), and follow-up of course of illness, cognitive status and treatment response to specific antipsychotic drugs. The goal of the study is to test a prior hypothesis about clinical subgroups in this population and to test whether these subgroups predict antipsychotic medication response.
The purpose of this study is to compare two clinical approaches to youth mental health care.
A dynamic analytical tool is being implemented to monitor the health, psychosocial and economic impacts of the COVID-19 pandemic as the crisis unfolds. A longitudinal survey is distributed via a network of hospitals, provincial/national organizations and web platforms. The survey information can be linked to provincial health administrative data and metrics derived from social media activity based on artificial intelligence methods. Targeted questions are included for critical populations such as healthcare workers and people with chronic illnesses.
The project will evaluate thermoregulatory processes among individuals with and without first-episode psychosis.
