Filter by:DELPhI acquisition and analysis software, a QuantalX Neuroscience development, which is designed to measure, analyze, and display brain electrical activity of human electroencephalogram (EEG), to transcranial magnetic stimulation (TMS), will be used to evaluate different psychiatric conditions.
The investigators will acquire simultaneous EEG and fMRI data from Veterans with depression and schizophrenia and mentally healthy Veterans to assess early sensory responses, context updating, and responses to emotional images. Understanding how rumination affects engagement with the environment is the first step towards assessing its far-reaching cognitive and emotional costs, which cut across traditional diagnostic boundaries. Understanding how mindfulness restores information processing will increase our understanding of how, and for whom, it works.
Repetitive Transcranial Magnetic Stimulation (rTMS) can modulate neuronal activity and has been shown to improve symptoms in patients with schizophrenia, but the underlying neural mechanism is unknown.This study hypothesized that repetitive transcranial magnetic stimulation of the cerebellar vermis can alter the ciliary-related functional connections in schizophrenia, thereby improving negative symptoms, cognitive function, and emotional symptoms. Therefore, this study will firstly explore the difference in cerebellar functional connectivity between patients and healthy controls, and on this basis, patients undergo a resting state functional magnetic resonance scan before and after rTMS intervention in the cerebellar vermis, and observe the cerebellar function connection in the treatment. Before and after changes, analyze the relationship between these changes and clinical efficacy to explore the neural mechanisms of efficacy.
Tobacco smokers with schizophrenia are known to be resistant smokers, with high rates of smoking and inability to quit in the long-term, often related to smoking relapse. This may relate to problems with frontal lobe function associated with schizophrenia, which make these patients have great difficulty in dealing with smoking withdrawal, urges and cravings. The current study will develop a combination approach that takes advantage of brain stimulation of the frontal lobes (repetitive transcranial magnetic stimulation (rTMS), in combination with the anti-smoking drug varenicline, to prevent smoking lapse using a well-established human laboratory method. Results from this study may have important implications for developing novel treatment approaches for smokers with schizophrenia.
Early intervention programs for psychosis help improve short-term treatment and recovery outcomes for individuals experiencing psychosis. OnTrackNY is a coordinated specialty care (CSC) program, developed to treat young adults within two years of experiencing a non-affective episode of psychosis. This project aims to expand the role of family engagement and support within the OnTrackNY model. Borrowing from the Needs Adapted and Open Dialogue models, the study team created a family therapy service that includes the client and members of his/her social network to navigate crises and assist in treatment planning. This service, Social Network Meetings, will be offered to individuals enrolled in the OnTrackNY@MHA program as an additional, voluntary, service option. The study proposes that the introduction of Social Network meetings may improve treatment and recovery outcomes.
Schizophrenia is a chronic disease with deficit in social interaction and lost of autonomy in daily life. Negative symptoms as blunted affect, avolition, social deficit and anhedonia and cognition were prognosis and functioning key's factors. Psychotropic medications have shown only poor effect to improve negative symptoms and cognition as attention, memory and cognitive flexibility. So, cognitive remediation programs were developped to focus cognitive disorders. The IPT (Integrated Psychological Treatment) is one of the most complete program with modules on cognitive and social abilities. The aim of this study is to evaluate the efficacy of IPT+ program to improve autonomy capacities of long stay inpatients suffering from schizophrenia 6 at the end of the program With IPT+ this study will improve autonomy capacities for patients suffering from deficit schizophrenia and allowed patients to go out hospital earlier than before.
In a double-blinded, randomized, parallel controlled design, patients with schizophrenia spectrum disorder will be exposed to a single dose of lipopolysaccharide (LPS) (LPS-patient). Clinical symptoms, blood samples, and brain imaging will be assessed at baseline and after LPS. There will be two comparison groups. Comparison groups include an age- and sex-matched healthy control group also exposed to the same LPS (LPS-control), and an age- and sex-matched sample of patients with schizophrenia on placebo (Placebo-patient). As in Phase I studies, multiple interim analyses are expected so the current design may be modified, which will be communicated during annual reports (21CFR312.30).
The main goal of this pilot study is to test the extent to which adjunctive treatment with the histone deacetylase (HDAC) inhibitor vorinostat improves brain plasticity and cognition in a pilot placebo-controlled trial in patients with schizophrenia who are on clozapine.
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.
Schizophrenia is a disease of young adults that affects 1% of the general population. According to numerous studies, it has been estimated that between 50% and 80% of patients with schizophrenia do not consider to have a mental disorder and are therefore not aware of their disorders. A poor degree of insight is associated with poor compliance, a higher number of re-hospitalizations, altered social and relational functioning, and a higher number of suicides and violent behaviors. This is why insight, which is an essential dimension of psychopathology, must be evaluated, as it depends to a large extent on the therapeutic alliance, adherence to treatment, likelihood of relapse and prognosis.
