Active clinical trials for "Psychotic Disorders"

This study will examine the safety and effectiveness of the antipsychotic drug olanzapine in children and adolescents with bipolar disorder or psychosis.

This research study aims to develop a brief group-based treatment called Resilience Training for Teens, then to test how well it protects high school students with mild symptoms of depression, anxiety, or having unusual feelings from developing mental illnesses.

The primary goal of this study is to examine the triglyceride/HDL ratio and the ischemic EKG changes in patients with schizophrenia, schizoaffective disorder or bipolar disorder.

This research concerns the study of language disorders of patients present in the spectrum of psychosis. It is indeed accepted that psychotic disorders are associated with language difficulties, which are only poorly highlighted thanks to reusable tools in clinical practice. These language disorders impact communication, and concern many linguistic domains, thus covering phonology, lexicon, semantics, morphosyntax and pragmatics. It therefore seems relevant to characterize these language disorders and to assess to what extent they interact with the other symptoms of the pathology, in particular the course of the thought disorder and the neuropsychological symptoms. In addition, this study is particularly interested in the interactions between working memory capacities and those related to syntax. It is intended for different patients suffering from psychotic disorders of different intensities, treated in the Psychotherapeutic Center of Nancy. Patients suffering from at-risk mental state (ARMS), first episode of psychosis (FEP) or schizophrenia will benefit from a complete language assessment, evaluating each domain mentioned above, on the expressive and understanding sides. The results of the language assessment will be compared with those of a control group in the same tests. They will also be analyzed with regard to the neuropsychological and psychiatric elements noted in the patient's medical file, in order to highlight possible associations between language skills, neuropsychological and psychiatric symptoms in this patient population.

Psychosis is a severe, common, and disabling psychological disorder. An epidemiological study conducted in England reported an incidence of 34 new cases per 100,000 person-years, with a peak between 16 and 19 years of age. Following a first psychotic episode, two clinical evolutions are possible: thymic psychosis (17%) and non thymic psychosis (83%). The first includes bipolar disorders with a psychotic component and major depressive disorders with a psychotic component; the second, other psychotic disorders, mainly schizophrenia. One of the major difficulties encountered is the frequent impossibility of specifying the type of psychosis at the beginning of the psychotic episode. However, these disorders require different therapies, particularly medication. This leads to a delay in diagnosis with a high risk of relapse. The semiological study of these diseases being carried out within the framework of interviews, it seems interesting to be able to record these and to obtain a quantitative and objective measurement through the study of language. The use of machine learning has made it possible to distinguish patients with schizophrenia from those with bipolar disorder by graphical analysis of language in a more efficient way than with clinical scales.Moreover, it is possible to identify linguistic markers: thus, an alteration of syntactic structures and prosody would be more present in non-thymic than in thymic psychoses. Paraclinical markers are also emerging. In particular, the link between inflammation and mental disorders.For example, an increase in IL-8 has been found only in thymic psychoses. At the radiological level, distinct changes in the volume of grey matter have been shown between thymic and nonthymic psychoses. In this context, it seems essential to be able to distinguish these disorders as early as possible through the combined use of clinical and paraclinical markers, and to be able to better understand their pathophysiology.

This study examines the use of contingent incentives to increase attendance at smoking cessation treatment sessions by smokers with schizophrenia and other psychoses who want to quit smoking. We hypothesize that participants randomized to receive contingent rewards for group attendance will attend more treatment sessions than those in the control group.

Treatment adaptation and implementation study for adult jail inmates with co-occurring substance use disorders.

The purpose of this study is to determine if zonisamide SR will prevent weight gain in schizophrenic subjects who take olanzapine (Zyprexa)

The main purpose of the protocol is to test the efficiency of art-therapy versus metacognitive rehabilitation on the visual perception disorders observed in patients with schizophrenia.

The purpose of this project is to obtain DNA, brain imaging data, other biological samples (e.g., urine, serum), and a comprehensive clinical assessment on patients with schizophrenia and other psychotic disorders, bipolar disorder, major depression, and normal volunteer controls. Understanding the physical and genetic factors related to these disorders will help us make progress in fitting treatments to an individual's needs. Participants will take part in a detailed clinical assessment, two blood draws, and an MRI scan over two visits. Participants will also be asked to provide urine and saliva samples.
