Filter by: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.
Background: The aims of this study were to explore the relationship between early reduction in psychotic symptoms and the ultimate response in patients with schizophrenia treated by atypical antipsychotics, and to determine the best time to switch or maitain the regimen. PI also explore the possible predictors for the clinical response. Methods: One hundred eleven inpatients with acutely exacerbated schizophrenia were randomized to give optimal therapy of olanzapine, risperidone, and paliperidone in one-week run-in period and 12 weeks' intervention. All participants were assessed using Positive and Negative Syndrome Scale (PANSS). Early Response, defined as reduction of 25% in PANSS score, was examined at weeks 1, 2, 3, 4 and 8, and these ratings were used to predict ultimate response (25% PANSS reduction) at week 12. PI hypothesized that early treatment response at Week 1 or 2 could predict Week 12's treatment outcome.
Adverse childhood experiences in psychotic disorders are associated with increased cognitive deficits, severe psychotic symptoms, and increased comorbidity. The number of different stress experiences also increases the probability of trauma-associated symptoms. Furthermore, neurobiological changes play a key role in the vulnerability of individuals with early traumas for mental and physical illnesses, among others for diseases of the schizophrenic spectrum disorder and the further course of the disease. The current project pursues a detailed recording of the course of symptoms in inpatients with psychosis to link this data with a systematic recording of childhood experiences and traumatic experiences and biological data. On a subsample of inpatients with psychosis and a comorbid post-traumatic stress disorder (PTSD), the researchers want to investigate whether symptom traits of existing psychotic disorders, biomolecular parameters and cognitive functions can be influenced by a trauma-specific treatment (NET), that has been proven to be effective in the treatment of PTSD.
The investigators conducted a randomized controlled trial to reveal the effect of tDCS on negative symptoms in patients with schizophrenia and its underlying mechanism using the neuroimaging and electrophysiology.
Schizophrenia is one of the most frequent psychiatric disorders with a prevalence of 0.5-1.0 % all over the world. It remains one of the major reasons for disability although medical and psychosocial interventions. People suffering from schizophrenia may also have many complex health troubles such as cardiovascular disease, metabolic disease, diabetes mellitus, and pulmonary problems. Researchers have been debating the utility of exercise over depression, anxiety, and obsessive-compulsive symptoms last decades. Studies indicate that physical activity improves mood, self-esteem, energy, motivation, concentration, cognitive skills, quality of life, and social interactions. Particularly in the last decade studies have been carried out showing that various exercise approaches and physical activities contribute positively to the physical and mental health of schizophrenic patients. Clinic impacts of these interventions, dominantly including aerobic exercise, strengthening and fitness training, also varied according to the type, duration and intensity of the method used. The knowledge obtained about schizophrenia patients point out that physically and mentally holistic approaches should be required to this complicated disease. Previous trials demonstrated that various physical activity or exercise methods have positive effects in patients with schizophrenia. However, to the best of the our knowledge, literature lacks investigation about benefits of Pilates on several domains, in particular about the potential changes on physical and mental health in patients with schizophrenia. The aim of this study was to investigate the effects of Pilates-based exercise training on the physical and mental health of schizophrenia patients.
The purpose of this study is to evaluate the feasibility of conducting a study of oral risperidone followed by paliperidone palmitate for once monthly (PP1M) and paliperidone palmitate for every 3 months (PP3M) in rwandan healthcare facilities with mental healthcare capabilities.
Schizophrenia is a major public health problem associated with cognitive deficits, such as short and long term memory, executive functioning, attention and speed of processing that are amongst the strongest predictors of impaired functional outcome. In addition, schizophrenia patients show reduced "plasticity", defined as reduced learning. D-serine is a naturally occurring activator of the N-methyl-d-aspartate-type glutamate receptors (NMDAR) in the brain, and this project will assess the optimal dose of D-serine treatment over three sessions of a program designed to measure auditory plasticity.
Berberine is an isoquinoline alkaloid extracted from medicinal herbs, has been demonstrated to produce beneficial effects on diabetes and hyperlipidemia, fewer study reported its modification on lipid metabolism in schizophrenia. Metformin, have been used for metabolic abnormalities in schizophrenia, findings from these studies indicated that they did have some effect,which are still in experimental stage.This study is aim to compare the efficacy and safety of berberine and metformin for preventing metabolic dysfunction in schizophrenia patients.
Agitation is characterized by excessive motor or verbal activity, irritability, uncooperativeness, threatening gestures, and, in some cases, aggressive or violent behavior. While agitation may have various underlying causes, patients with schizophrenia are especially vulnerable to acute episodes of agitation, especially during exacerbation of disease, and clinicians do not always diagnose these episodes early enough. Agitation associated with psychosis is a frequent reason for emergency department visits, and unless it is recognized early and managed effectively, it can rapidly escalate to potentially dangerous behaviors, including physical violence. Educating psychiatric professionals about the timely and accurate diagnosis of agitation among patients with schizophrenia or bipolar disorder and developing a well-tolerated easily administered medication will contribute to the prompt and effective management of this condition and could help reduce the risk of violent behavior and other undesirable outcomes. This study is designed to identify the ideal dose range and tolerability of sublingual Dexmedetomidine in patients with schizophrenia.
This study will assess the effects of D-serine adjuvant treatment to the ongoing pharmacological treatment of schizophrenia patients that are resistant to treatments.
