Filter by:Patients with schizophrenia show enhanced dopamine synthesis capacity and release, an effect that can be evoked in healthy subjects by repeated amphetamine administration. Therefore for the first time the relationship between dopamine synthesis and release will be studied in healthy subjects before and after amphetamine sensitization in order to better understand adaptive mechanisms of the dopamine system.
Locomotor, transport and information functions in human body systems are carried out by active media in autowave regimes! Any living organism is a (micro-macro-mega) hierarchy of autowave subsystems-an ensemble of loosely coupled subsystems of a simpler structure. From the highest levels of the hierarchy, Autowave Codes-Signals arrive, which determine the transitions of subsystems from one autowave regime to another Autowave interaction (of Complex Coherent Action). Autowave interaction is a process associated with the evolution and interaction of spatial and wave structures in the active media of the organism. Chaos in organism functioning tells about health. Periodicity - Autowave reverberator may presage a disease - Autism Spectrum Disorder; Chaotic nature of oscillations in active media of physiological systems is more optimal for their vital functions than periodic one. Firstly, systems that function in chaotic regimes, can re-arrange themselves faster and easier in case of change of environmental conditions, i.e. the so called adaptive control is more easily implemented in them. Secondly, "spreading" of oscillations strength along comparatively wide frequency band takes place in chaotic regime. When an organism is young and healthy, physiological systems show the elements of chaotic behavior, i.e. irregularity and chaotic dynamics are the extremely important characteristics of health. Decrease in changeability and appearance of stable periodicity of Autowave reverberator are often connected with Autism. The main purpose is to study brain plasticity (the changes that occur in the brain through Autowave reverberator) in children with autism. Research suggests that during development, the brains of children may change in response to their Autowave reverberator differently than the brains of typically developing individuals. Investigators want to understand why and how this difference may contribute to the symptoms of autism spectrum disorder (ASD). In this study, the investigators will be examining the effects of non-invasive neuromodulation SQUED™ series 28.1 home-use for Treatment of Autowave reverberator of Autism. Integrative Team World Organization of Medical Synergetics (WOMS) - collaborations between physicians and researchers with expertise in biostatistics, physics, mathematics, engineering, and computer science.
The purpose of the study is to evaluate the feasibility and efficacy of the group-based intervention "Honest, Open, Proud" among soldiers with mental illness.
Rationale: There is growing consensus that targeting negative symptoms such as social withdrawal is essential to be able to preserve social participation, thereby reducing the high yearly costs of schizophrenia. Aaron T. Beck, founder of Cognitive Behavioural Therapy (CBT), and colleagues have developed and investigated a new CBT approach, in which they target inactivity in a chronic schizophrenia population with severe negative symptoms The therapy is based on accumulating evidence that dysfunctional beliefs in conjunction with neurocognitive impairments can impede social functioning. These results suggest that CBT can be highly successful in establishing clinically meaningful improvements. However, the therapy has not yet been investigated in a recent-onset population. Objective: To evaluate the applicability and (cost-) effectiveness of a shortened, partly group based, Cognitive Behavioural Therapy focussing on social activation (CBTsa) in patients with recent onset schizophrenia. Hypotheses: 1) the investigators hypothesized that CBT focused on social activation (CBTsa) in a recent-onset population will result in a substantial reduction in severity of negative symptoms, in particular social withdrawal. 2) The investigators expected that CBTsa would lead to an improvement in terms of Quality of Life and overall functioning. 3) The investigators expected this intervention to result in a reduction in need for care and QALY gain as a consequence of improvement in symptoms and social functioning. Study design: Single blind randomized controlled trial with 6 month-follow up. Study population: Patients between 18 and 35 years old with negative symptoms of at least moderate severity, and who have been recently (< 2yrs) diagnosed with schizophrenia. Intervention (if applicable): Individual and group-based CBT intervention targeting social withdrawal. Main study parameters/endpoints: Change in negative symptoms, Social functioning, and quality of life, Productivity losses.

comparison of intramuscular olanzapine and ketamine efficacy as first medication for fast sedation of patients with agitation and aggressive behavior. Five hundred patients with agitation caused by psychiatric disorder were randomly assigned under double-blind conditions to receive olanzapine or ketiapine. The Overt Agitation Severity Scale, Overt Aggression Scale and Ramsay Sedation Scale will be applied within 12 hours after the first dosage.
Social cognition concerns the understanding of how people think about others and how that, in turn, influences our behavior, feelings, and social interactions. schizophrenia social-cognitive impairment is profound (effect size D>1.2), medication resistant and critically limits functional well-being . Social cognition involves complex patterns of coordinated activity within numerous cortical and subcortical networks, making it a difficult target for clinical neuroscience investigation. Yet, prior research demonstrates that sensory-perceptual dysfunction in schizophrenia can upwardly generalize into higher-order social-cognitive impairment making perception a tractable and fruitful approach for studying social cognition in schizophrenia. Here, the investigators explore how distortions in perception of temporal coincidence can contribute to the aberrant inferences of physical causation and social agency.
The validity and the sensitivity of different measures implemented in the web application StayOk are investigated. The measures are used primarily for the assessment and the early identification of psychosocial risks. Secondarily, the results of the assessment are applied to generate health-promoting advices for the user of the web application.
Development of interventions that can effectively target and remediate the cognitive and functional impairment associated with serious mental illness is a treatment priority. Transcranial direct current stimulation (tDCS) is a safe, non-invasive neuromodulation technique that is capable of stimulating brain activity to facilitate learning. The primary objective of this study is to evaluate the pairing of two therapeutic techniques, cognitive remediation and tDCS, as a cognitively enhancing intervention. This study is designed to test the hypotheses that cognitive remediation paired with tDCS will be more efficacious than cognitive remediation delivered with sham stimulation and that intervention-induced cognitive change will be sustainable. To examine the incremental benefit of pairing tDCS with cognitive remediation, clinically stable outpatients between the ages of 18-65 who have a diagnosis of schizophrenia, schizoaffective disorder, or bipolar disorder will be enrolled in a double-blind, double-baseline, sham-controlled clinical trial. Participants will be randomized in a 1:1 ratio to receive either tDCS or sham stimulation concurrent with working memory focused cognitive remediation. Training will be offered to participants in a small group format. Training will consist of 48 sessions, with 2-3 sessions scheduled in a week. Each training session will last 2 hours. One hour will be spent completing cognitive exercises that require working memory skills on a computer. TDCS or sham stimulation will be offered concurrent with the first 20 minutes of training with a StarStim neuromodulator. One mA of anodal stimulation will be applied to the left dorsal lateral prefrontal cortex and the cathodal electrode will be placed in the contralateral supraorbital position. Upon completion of working memory training, participants will transition to a 45-minute bridging group focus on application of cognitive skills in everyday life. To assess intervention-induced change, working memory, other aspects of cognition, functional capacity, community functioning, and symptom severity will be assessed pre- and post-intervention. Sustainability of intervention-induced change will be assessed with an assessment session 6 weeks post-intervention. Mixed effect, repeated measure ANOVAS will be used to analyze intervention-induced change.
This study aims to evaluate the therapeutic effect of low frequency rTMS over the right DLPFC, versus right OFC versus Sham group of obsessive-compulsive disorder (OCD) patients. Sixty patients will be recruited from the out-patient psychiatric clinic of a university hospital, and randomized into three equal groups. The 1st group will receive 10 sessions of low frequency rTMS targeting right DLPFC by means of a butterfly coil, 120% RMT, 1 Hz, 3 trains, each of 500 pulses with a 40 seconds inter-train interval allowing the coil to cool. The 2nd group will receive 10 sessions of low-frequency rTMS over the right orbitofrontal cortex (OFC), the international 10-20 EEG system will be used to position the coil over the right OFC, at the right frontopolar 2 (Fp2) electrode site, using the following parameters: 120% motor threshold, 1 Hz, 3 trains, each of 500 pulses with a 40 seconds inter-train interval allowing the coil to cool. The 3rd group will receive sham stimulations with the same pulse delivery as the other groups but with the coil placed perpendicular to the scalp. The resting motor threshold (RMT) and cortical silent period (CSP) at different intensities from 110 % to 150 % will be measured before and after the end of sessions. All assessments like (Y-BOCS), (HAM-A), Beck Depression Inventory, (CGI-S), (MoCA) will be performed before and after end of the sessions and 3 months later.
