Filter by:This proposal will examine measures of neuroplasticity (the brain's ability to alter its function or structure in response to changes in the environment or novel experiences) in Veterans with schizophrenia or traumatic brain injury (TBI). Both conditions are associated with impaired cognition (for example, attention, memory, learning), which is in turn associated with poor community functioning and integration. However, the two disorders differ in their origins: schizophrenia is a neurodevelopmental disorder appearing usually in late adolescence while TBI is an acquired disorder as the result of an injury to the head. Understanding of the root causes of complex cognitive impairments associated with these disorders remains limited. Neuroplasticity is a fundamental brain process that underlies cognitive functioning and may give insight into the causes of cognitive dysfunction in TBI and schizophrenia. Neuroplasticity will be measured using electroencephalography (EEG) by placing small electrodes on the scalp that record the brain's electrical activity. Participants will listen to simple auditory tones and view simple visual patterns while their EEG is recorded. Additionally, participants will have measures of cognition and clinical interviews for diagnosis of a disorder as well as any current levels of symptoms.
The aim of this study is to evaluate a new SV2A tracer, [11C]APP311, in healthy aging and neuropsychiatric disorders including psychotic disorders and cannabis use disorders.
Schizophrenia is a severe, often chronic mental disorder, characterized by positive and negative symptoms and cognitive deficits. The serotonin hypothesis of schizophrenia was proposed in the 1950s, but only recently, pimavanserin, the first antipsychotic medication with selective affinity for the serotonin 2A receptor was approved. The aim of this translational proposal is to test the clinical validity of the serotonin hypothesis of schizophrenia and to guide development of operational, objective criteria for stratification of first-episode schizophrenia spectrum patients before antipsychotic treatment. Our previous data have strongly suggested, that a subgroup of antipsychotic-naïve patients will respond to serotonin 2A receptor (2AR) blockade. This treatment will cause minimal side-effects compared with conventional dopamine D2/3 receptor blockade. In this Danish, investigator-initiated trial, we will establish a cohort of 40 antipsychotic-free, first-episode schizophrenia spectrum patients and enrol them in a 6-week open label, one-armed trial with selective serotonin 2AR blockade (pimavanserin). Before initiation of pimavanserin patients will undergo: positron emission tomography (PET) imaging of the serotonin 2AR binding potential using the radioligand [¹¹C]Cimbi-36; magnetic resonance spectroscopy (MRS) of cerebral glutamate levels; structural Magnetic Resonance imaging (MRI), including Diffusion Tensor Imaging (DTI); cognitive and psychopathological examinations; Electrocardiography (ECG), and blood sampling for genetic- and metabolic analyses. Matched healthy controls will undergo parallel examinations, but not medical treatment and PET . ACADIA Pharmaceuticals Inc. provides the study medication (pimavanserin). ACADIA had no influence on study design and will not take part in data processing or publication of the results of the study.
This study evaluates the addition of rituximab to 12 patients diagnosed with treatment resistant schizophrenia spectrum disorder in an open trial.
This study evaluates PERSERIS at a higher dose than what has been administered in previous clinical trials. Subjects with stable schizophrenia on a dose of 5-6 mg oral risperidone will be switched to PERSERIS at the higher dose, which is believed to be similar to the oral dose
There is compelling evidence that longer duration of untreated psychosis independently predicts negative outcomes. The proposal aims to explore whether targeted and proactive online outreach through search engine advertisements, coupled with engaging, informative, and interactive online resources, can effectively reduce the duration of untreated psychosis and facilitate earlier treatment initiation in New York State. Results from this initiative will be critical to informing the subsequent design and conduct of larger, focused, and proactive digital media campaigns targeting patient with First Episode Psychosis and their caregivers online, intended to accelerate linkage to care and reduce the duration of untreated psychosis throughout the U.S.
This study aims to test the hypothesis that addition of Individual Placement and Support (IPS) and/or Cognitive Remediation Therapy (CRT) in addition to treatment as usual in patients with early psychosis will be feasible and acceptable in patients with early schizophrenia.
Schizophrenia is a mental health issue that affects mostly young adults. The main symptoms are hallucinations, delirium, and agitation, poor social relations, lack of motivation, thought disorganization. Also, patients suffering from schizophrenia encounter important cognitive disorders affecting memory, executive functioning and attention. These cognitive alterations are often linked to social exclusion and stigmatisation. Antipsychotic treatments are effective mainly on the positive dimension of symptoms (hallucinations etc…); however their action is very limited on the cognitive difficulties encountered. Psychosocial techniques can be used to treat the cognitive symptoms, such as cognitive remediation or psychosocial rehabilitation . These cognitive difficulties mainly have an impact on patients' daily life, affecting their abilities to drive, for example. Schizophrenic patients suffer more road accidents than healthy subjects . Thus, considering this information, it appears important to us to address this driving problem for various reasons: - Firstly, knowing how to drive is often linked to daily autonomy, - Secondly, driving is also linked to keeping an active social network and to work. Patients suffering from schizophrenia often encounter difficulties in learning how to drive which reinforces the stigmatisation and fear of failure. Thus, a specific driving and theory training prior to driving lessons could be a way of helping patients in their cognitive difficulties and pass their driving test. Daily transports mobilize a number of cognitive functions (attentional vigilance, working memory, psychomotor coordination, divided attention, visuo-spatial abilities . Using a driving virtual reality tool could constitute an ecological cognitive remediation tool, by simulating daily driving situations. This "serious game" approach enables us to involve virtual reality in training but also in assessments. The driving simulator allows standardized evaluations and could also become a therapeutic tool of ecological cognitive remediation. This study thus appears interesting in order to develop road safety and daily autonomy.
Self-stigma refers to the transformation process wherein a person's previously held social identity is progressively replaced by a devalued and stigmatized view of oneself termed "illness identity". Self-Stigma is a severe problem in Serious Mental Illness (SMI). Self-stigma prevalence is high (41.7% of the 1229 participants with SZ and 21.7% of the 1182 participants with mood disorders had moderate to high levels of IS in the GAMIAN-Europe study). Self-stigma was negatively associated with self-esteem, social function, wellbeing, quality of life or personal recovery and positively associated with psychiatric symptoms and depression. Several psychosocial interventions (mostly combinations of psychoeducation and cognitive behaviour therapy) have been designed to reduce self-stigma and its impact on clinical and functional outcomes, with preliminary effects on self-stigma, insight and self-efficacy. Narrative Enhancement and Cognitive Therapy (NECT) is a manualized structured 20-session group-based intervention . Conducted by two trained facilitators the sessions combine psychoeducation, cognitive restructuring and story-telling exercises to reduce self-stigma. Developed in USA, NECT was adapted in Israel and Sweden. NECT showed effectiveness in reducing self-stigma and in improving self-esteem and quality of life. Despite being effective on changing coping strategies, NECT effectiveness on social function is still unclear. The present study aims to validate NECT French adaptation and to evaluate its effectiveness on social function, self-stigma, psychiatric symptoms, self-esteem, wellbeing, quality of life and personal recovery in SMI participants (schizophrenia, bipolar disorder, borderline personality disorder)
Some people who have what doctors currently call schizophrenia or bipolar disease may actually have a brain disease caused by auto-antibodies. Auto-antibodies are produced when the normal defense mechanism of the body goes wrong and begins to attack the body, similar to "friendly fire." Auto-antibodies attack brain receptors and then the person who has this problem begins to have hallucinations and other manifestations of schizophrenia, like feeling that people can see what they are thinking and also feeling that other people do not like them. If this disease is caused by auto-antibodies, typically the person is well until they are 15 years of age or older, but seldom older than 35 years. Then, in a matter of a few months they begin to have hallucinations and the other symptoms. Doctors still do not know whether some people with schizophrenia or bipolar disease have auto-antibodies attacking their brain. For this reason, in this study some of these patients will receive a treatment that suppresses the auto-antibodies and their symptoms after treatment will be compared with the symptoms of a group of similar patients who are given a preparation that looks like the real treatment, but it is not.
