Filter by:Bipolar disorder is a chronic and frequent mood pathology, that impacts on emotional and socio-professional life of sick subjects, and also increase mortality by suicide. Suicide is considered as a bipolar disorder result. The main goal of this study is the endophenotype characterization from a clinical and cognitive point of view, of a bipolar spectrum's disorder present in a family, and then highlight a mutation of one of the genes involved is this disorder.
To evaluate effect of slow-release melatonin (Circadin) on REM sleep behavior disorder.
Conduct disorders are defined as "repetitive and persistent pattern of behavior in which the basic rights of others or major age-appropriate norms are violated". So defined, these disorders are at the crossroads of psychiatry, social field and justice. Conduct disorder management is a public health issue and a societal question. Conduct disorders affect 5 to 9% of 15-year old boys. Care management of children and adolescents admitted for disruptive behaviors in emergency rooms is an issue. No consensus or official recommendation exists. However, use of emergency care in this context is increasing in most western countries and it exposes to several risks (inappropriate use of hospitalizations, social rupture, ignorance of comorbidities and suicide risk). The Trajectories project is designed to describe children and adolescents with disruptive behaviors, their care management and to follow their life trajectory and psychiatric evolution after admission to emergency rooms. Better understanding this population will improve their medical and social care management, thereby giving professionals the right tools. The main objective of this project is to implement a multidisciplinary and integrative research combining clinical considerations and social sciences to determine the "trajectory" of this population.
The main purpose of the study is to examine to which extent abnormalities in the dynamics of neural activities observed in patients with psychosis is related to difficulties at ordering simple visual stimuli and/or personal events.
This research study is designed to look at the involvement of the glutamate system in depression. Each subject will undergo a screening appointment to determine study eligibility. Thereafter, the study will take 2 or 3 visits depending on schedule availability and will consist of one MRI scan, and PET scan. Subjects will also participate in cognitive testing. Depending on camera time, staff availability and subject schedule, total study participation may last 1-2 months.
The purpose of this trial is to explore parent-child interactions in parents with and without psychosis, and ascertain whether a brief (10 week) supported self-help parenting program offered to parents in their own homes can help improve parents' self-efficacy and general well-being, as well as interpretations of their parent-child relationship and child behaviour in children who are 3-10 years old.
Objectives 1. to develop and validate a Computerized Adaptative Testing (CAT) of self-perceived quality of care in Psychiatry. 2. to analyze the implementation of this new measure in clinical practice : qualitative analysis of the relationship patient/professional.
The study is a epidemiological, cross-sectional study in a mainly rural area of Denmark in Denmark. Life expectancy is shorter, morbidity is higher, and social problems more prevalent than in the urban areas of the country. The population study aims at examining complexities of environmental, hereditary, lifestyle, and social factors as determinants and predisposing factors for morbidity, health, and quality of life. The study will cover physical, mental, and social dimensions and examine family patterns and subgroups. The study will provide baseline information for later follow-up.
The perception of music requires coordinated neural activities in distributed multi-functional centers across both hemispheres. The association between musical abilities and other general cognitive functions have been studied in several populations with inconsistent results. Schizophrenia is a major mental disorder that is strongly associated with cognitive deficits. These often appear before the onset of psychotic symptoms and persist throughout effective treatment of positive and negative symptoms. Like other disorders of psychosis, schizophrenia features general deficits in auditory memory and sensory processing. Recently, Sawada et al. (2014) and Wen et al. (2014) studied music abilities in Japanese and Chinese schizophrenic populations. They both used a standardized assessment for amusia called Montreal Battery of Evaluation of Amusia (MBEA) and found marked impairments in perception of scale, contour, interval, rhythm, meter and memory. Both studies showed that deficits in music perception were associated with cognitive deficits and negative symptoms. In regards to positive symptoms, Wen et al., but not Sawada et al., found a significant association. The present clinical study will assess musical abilities using the MBEA in a Canadian population with and without refractory psychosis. It will explore associations between musical deficits, positive and negative psychiatric symptomology and cognition. The patient population will have a diagnosis of schizophrenia, schizoaffective disorder, affective disorder with psychosis or non substance-related psychosis who were referred to the British Columbia Psychosis Program (BCPP) due to inadequate or no response to at least two trials of antipsychotics. A focus on refractory psychosis may provide greater insights because these patients have relatively more pronounced psychiatric symptoms and cognitive deficits. It will also be valuable to administer the MBEA assessment on a Canadian population, because the test was originally intended for Western populations and its musical phrases were designed with Western tonalities.
The purpose of this study is to determine if candidate polymorphisms in brain-derived neurotrophic factor (BDNF) and catechol-o-methyl transferase (COMT) are predictive of psychosis disorder severity, symptomology, and resolution in patients at BCPP. A secondary objective will be to form a biorepository of blood and saliva samples from patients at BCPP so that further genetic, proteonomic and pharmacogenomic studies may be done to gain insight into the genetic basis of differences in psychosis disorder presentation and manifestation, and differences in response to antipsychotic drug treatment.
