This randomized, sham-controlled, double blind, multicentre clinical trial aims at providing evidence for the efficacy and safety of continuous theta burst stimulation (cTBS) in the treatment of auditory hallucinations in patients with schizophrenia. Overall, the study will include 137 patients. Because of the adaptive study design, an interim analysis was performed after half of the originally planned patients (43/86), according to which the sample size was increased by 51 patients). Each patient will receive a three weeks course of daily (5/week) treatment; 50% of the patients will be treated with cTBS (1200 impulses daily), the other half with a sham stimulation to the left and right temporoparietal cortex. Sham stimulation will be applied by an active sham-coil that allows for a double-blind treatment. Follow-up assessments 1, 3 and 6 months after treatment will investigate the stability of treatment effects.
The primary objective of this study is to evaluate the long term safety and tolerability of ALKS 3831 in subjects with schizophrenia.
Social cognition and interaction training (SCIT), a group-based treatment that aims to improve both processing social information and functioning, may be an effective treatment for enhancing the social skills of people with schizophrenia. This study will compare the effectiveness of Social cognition and interaction training (SCIT) versus treatment as usual (ETP) in helping people with schizophrenia improve their social cognition and social functioning so specially on negative symptoms. Many studies show a connection between negative symptom and social cognition in schizophrenia.
The deficit of awareness of pathology (or insight) is a common symptom in patients with schizophrenia and has a negative impact on the prognosis of the disease. Current treatments aren't effective enough on this symptom (Pijnenbord et al., 2013). Previous studies have shown a positive impact of videos of patients themselves on insight but they lacked power. This technique needs more investigation. The study aims to improve the patient's awareness of pathology with a video of themselves recorded in the acute phase of their illness. Patients will watch this video after clinical stabilization. This is a randomized controlled and single blinded trial. A population of 60 patients (30 in each group) will be included. The impact on the insight, symptomatology, treatment adherence and functional remission will be evaluated. The video of patient is useful for a personalized clinical follow-up. Its use for therapeutic purposes would be innovative and could be extended to other applications in psychiatry, especially as this tool is readily available.
Maintenance of employment is dependent upon being able to successfully integrate into one's work setting. This can present a significant challenge to individuals with serious mental illness, as they typically exhibit impairment in their ability to accurately perceive and understand social exchanges. Presently the most established intervention is Social Cognition and Interaction Training (SCIT), a 12-week group intervention in which participants learn strategies to enhance emotion recognition and to assess the accuracy of their interpretation of social interactions. To enhance transfer of training gains to functional outcomes, participants will be paired with a social mentor to facilitate completion of homework and to ensure that skills are practiced outside of treatment (supported SCIT). The study will examine the impact of supported SCIT on social and work role functioning. The specific aims are: 1. To assess the feasibility of providing supported SCIT to individuals with serious mental illness who are engaged in compensated work activity. 2. To assess the impact of supported SCIT on social cognitive skills as well as work and social performance. 3. To assess durability of intervention-induced change 3 months after the end of intervention. A single blind study will be conducted in which participants between 18-70 with serious mental illness (schizophrenia, schizoaffective disorder, and bipolar disorder) are assigned to 12 weeks of supported SCIT. Intervention will consist of one 2-hour small group training sessions and 30 minutes of individualized supported practice of skills with a treatment facilitator weekly. Feasibility will be assessed with attendance at group and individual sessions. Baseline, post-intervention (3-month), and follow-up (6-month) assessments will measure social cognitive abilities and functional outcomes. Potentially confounding variables such as symptom severity and outside treatment hours will also be assessed. It is hypothesized that supported SCIT will be completed by at least 75% of veterans. The intervention is predicted to improve social cognitive skills and social and work performance. Training gains are expected to be sustained 3 months after intervention.
The project aimed at identifying neuropsychobiological signatures of pharmacological sex-steroid hormone manipulations in healthy women as a risk model for depression. The study is a double-blind, randomized, placebo-controlled study. Investigators included 63 healthy female volunteers with regular menstrual cycles between 23 and 35 days. Participants were randomized to active Gonadotrophin-Releasing-Hormone agonist (GnRHa) (goserelin 3.6 mg implant) or placebo (saline injection) intervention, which was initiated in the mid follicular phase (i.e. cycle day 22.6 ±2.5). Sixty women completed follow-up and entered the analyses, except for a few drop outs on some domains. The following domains were addressed at baseline and at follow-up (16±3 days post intervention), (which corresponded to the early ovarian suppression phase of the biphasic hormone response to GnRHa): 1) serotonin transporter binding as imaged by 11CDASB Positron Emission Tomography (PET), 2) functional Magnetic Resonance Imaging (fMRI) emotional processing, 3) fMRI reward processing, 3) rating state fMRI (rsfMRI), 4) structural MRI, 5) Neuropsychology, 6) Psychophysiology, 7) Hypothalamus-Pituitary-Adrenal cortex (HPA)-axis dynamics, 8) Peripheral markers of immunoactive cell responses, 9) Epigenetic factors. Psychometrics in terms of self reported mental distress and interview based ratings were monitored across the intervention period to monitor potential symptoms of mental distress and psychopathology. Also ovarian hormone responses, peripheral blood markers, and side effects scores were collected across the intervention period.
In people with schizophrenia or people with autism, impairments of social cognition are a core feature of the disease and, according to researchers who represent valuable references on this subject for the international community, three to five processes of social cognition are usually altered in those diseases: (1) emotional processing which is the ability to identify emotions through facial expressions, gestures, and tone of voice, (2) theory of mind (ToM), which is defined as "the ability to attribute mental states (beliefs, intents, desires, …) to oneself and others, and to understand that others have beliefs, intentions, and desires that are different from one's own", (3) attributional style which refers to how people explain the causes of positive and negative events, and corresponding, in schizophrenia, to self-serving and personalizing bias that means a tendency to blame others for negative life events rather than sharing the responsibilities between different sources; and (4 and 5) social perception and knowledge, which can be defined as decoding and interpreting social cues from others, taking the social context into account, and knowing social rules, roles, and goals. Components of social cognition appear to be related to both symptomatology and functioning in everyday life. The present study aims to assess a new social cognitive battery developed by several teams in France: ClaCoS.
The study will be a 6-month, open-label, multiple center study in approximately 50 stable subjects diagnosed with schizophrenia or schizoaffective disorder to evaluate the safety, tolerability, and pharmacokinetics of Risperidone and 9-OH-Risperidone following implantation of two or three, 300 mg Risperidone Implants.
Brief Summary: In schizophrenia, dislocation of psychic functions involving a loss of contact with reality is frequently found. A fragmentation of motor and sensory perceptions could be held responsible. However, automatic integration between perception and action is the necessary condition to be in "relationship with the world." Affordance is the experimental link between object perception and potentially associated actions (Gibson, 1977, 1979) explored by Stimulus Response Compatibility (SRC) paradigm. With Tucker & Ellis sensory motor compatibility task (1998), with a modified response device (responses given with grasp), we study the impact of motor activation on these affordance effects. In this study, a group of controls will also be included in order to understand, as precisely as possible, the mechanisms involved (i.e., interference between the perception of the object and the response gesture).
