Filter by:The selection of antipsychotic in early stages of the illness is mainly determined by its clinical effectiveness. Second generation antipsychotics (SGAs) are the first line drug treatment for individuals suffering from schizophrenia. It is clear that SGAs are not a homogeneous group and clinical effects and profile of side effects differ between SGAs. Differences among antipsychotics in terms of effectiveness have turned out to be a topic of increasing research interest, although comparisons between the different SGAs are scarce. In first episode of psychosis, SGAs have shown a higher treatment effectiveness compared to first generation antipsychotics (FGAs) (findings primarily driven by Haloperidol). Less evident seems to be the notion that some of the SGAs might be more effective (in terms of treatment discontinuation) than others. Most of the medium-term randomized studies have shown similar rates of all-cause treatment discontinuation in first episode patients treated with different SGAs. It may be concluded that more randomized controlled trails should be accomplished to determine the position of frequently used SGAs in clinical practice. Investigators undertook this study with the major objective of comparing the clinical effectiveness of three widely utilized SGAs (Aripiprazole, Ziprasidone and Quetiapine) in the acute treatment of first-episode non-affective psychosis individuals at 3 years of follow-up.
During this study the investigators will 1) collect measures of social cognition and social functioning in adolescents and young adults who are experiencing early symptoms of a major mental disorder; and 2) evaluate the predictive value and utility of a new role functioning assessment measure for individuals experiencing changes in their lives after an index episode of mental illness. This will happen in the context of providing treatment-as-usual to individuals who arrive seeking help with the early phases of mental illness.
The purpose of this study is to find out the time it takes to absorb, distribute, breakdown and remove the drug from the body in healthy participants and subjects with schizophrenia and whether it causes any side effects.
Cannabidiol (CBD) is a component of herbal cannabis that is present in varying concentrations in cannabis extracts. CBD has been shown to produce central effects including hypnotic, anticonvulsive, anxiolytic and neuroprotective effects.The investigators hypothesize that treatment with CBD will result in: 1) Improvement evidenced by a reduction in scores on the Positive and Negative Syndrome Scale for Schizophrenia (PANSS), 2) Improvement evidenced by a reduction in the Clinical Global Impression of Severity scale (CGI); Secondary Hypothesis: 1) Greater improvement in functioning as measured on the "Patient Assessment of Own Functioning Inventory: (PAOFI) and the Quality of Life Scale (QLS) In this 2 period cross over design, subjects will be randomized in a 1:1 ratio to receive either: Order 1: CBD (Period 1) followed by placebo (Period 2) or Order 2: Placebo (Period 1) followed by CBD (Period 2) under double-blind conditions. The 2 study periods will be separated by a washout of at least 2 weeks. During each period subjects will receive study medications (CBD [total 800mg/day] or placebo) for a period of 4 weeks.
The prediction of dangerousness remains a delicate subject, relevant in current psychiatry. Scalable psychopathological elements identified in schizophrenia and mood disorders are considered as most at risk for crime committing. The French High Authority of Health (HAS) recommends to identify and prevent risk situations of violence and to develop research at this level. Some authors have worked on criminal career and became interested in risk factors for aberrant driving behaviors but also in environmental or clinical elements accompanying these phases. To our knowledge, no specific study about contextual elements before misconduct and which could lead to aberrant driving behaviors among individuals diagnosed with antisocial personality disorder has been described to date The investigators propose to follow individuals diagnosed with antisocial personality disorder in prison during 6 months in order to list their conduct disorders and contextual elements upstream of these misconducts. The investigators will also study the effect of contextual factors related to judicial steps on the appearance of aberrant driving behaviors.
The study evaluates the gene-environment interaction of the COMT-genotype on the effects of the phytocannabinoids delta-9-tetrahydrocannabinol, cannabidiol or a combination of both on induction of psychotic symptoms, endocannabinoid levels in human body fluids, neuronal processing, and neural oscillations. In addition the effects of the phytocannabinoids on lipid levels in serum and cerebrospinal fluid, cognition, neuronal processing assessed by fMRI as well as D2-receptor availability assessed by [18F] desmethoxyfallypride.
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 purpose of this study is to evaluate the impact of genetic testing on healthcare decisions and patient outcomes for patients suffering from pain, cardiovascular problems, Arthritis, Type II Diabetes, and/or Mental Health disorders. Results of genetic testing will also be compared with the clinical outcome measures collected to discover novel genetic factors that may influence patient care.
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.
Purpose of study is to evaluate impact of brief motivational interviewing vs. feedback on learning styles in improving attendance to cognitive training
