Active clinical trials for "Schizophrenia"

It has been known that schizophrenia patients have a reduced ability to recognize both their own pain and the pain of others. The patients' pain judgement is not correlated with their affective or cognitive empathic capacities. These results suggest that changes in pain recognition in schizophrenia patients reflect specific dysfunctions in pain processing . Schizophrenia patients have a reduced ability to recognize both their own pain. This deficit is not related to their empathic capacities . The correlation between pain perception in schizophrenia patients and their ability to evaluate their own pain is still unknown. Pain insensitivity to pressure has been described in the context of schizophrenic illness was also evident in the biological relatives of those with the disorder. It is still unclear whether relatives of schizophrenia patients have aberrations in assessing their own pain in different imaginary situations. Animal models are important tools in the study of psychiatric disorders and the mechanism of action of antipsychotic and other psychiatric drugs. Positive symptoms of schizophrenia are difficult to model in rodents, but locomotor hyperactivity in response to a novel environment were reported as correlated with positive symptoms . On the other hand, negative symptoms such as social interaction and anhedonia and cognitive processing (e.g. emotional memory, sensorimotor gating, and associative learning) can be investigated in animal models with a high degree of validity . Furthermore, in most schizophrenia-like animal models, both first and second-generation antipsychotic drugs are reported to be effective in ameliorating behavioral abnormalities. It is well establish that patients with schizophrenia have been shown to display decreased sensitivity to pain, and antipsychotics are used to treat chronic pain. For example, chronic administration of phencyclidine or ketamine, psychomimetic drugs, produces decreased sensitivity to mechanical stimulation, and increased pain tolerance. The classic antipsychotic drug fluphenazine has anti-allodynic properties in multiple rodent models of nerve injury-induced neuropathic pain. An analgesic effect of quetiapine in the Cancer-induced bone pain animal model have been demonstrated. However, the mechanism of action to relive pain is still under debate and may differ between different agents. Animal models of acute and chronic pain allow evaluating the effects of analgesics drugs and other components on pain sensation and transmission, and underlining their molecular mechanism. Usually, these tests rely on an escape behavior or a withdrawal reflex as an index of pain. One known method of measuring responses to thermal stimuli involves application of a noxious thermal stimulus (hot or cold). This method has been used in order to investigate new analgesic components. Study hypothesis Schizophrenia patients and their biological relatives who have an aberrant sensation of pain also have a reduced capability to evaluate their own pain. Primary objectives Demonstrate that schizophrenia patients who suffer from pain insensitivity also have a reduced capability to evaluate their own pain, compared to population without a mental illness. Prove that the severity of pain insensitivity in schizophrenia patients is correlated to the degree of their ability to assess their own pain in different imaginary situations. Secondary objective Demonstrate that healthy biological relatives of schizophrenia patients have aberrations in assessing their own pain. Find the correlation between pain insensitivity in schizophrenia patients to pain insensitivity in their relatives. Find the correlation between the degrees in pain recognition in schizophrenia patients to pain recognition in their biological relatives. Investigate the impact of anti-psychotic drugs on pain threshold of schizophrenia patients. Study design This study is a prospective cross-sectional trial.

The major target of the study is to confirm the safety and efficacy of our augmented protocol of theta-burst TMS in schizophrenia. Our aim is to confirm the beneficial effects of rTMS treatment on multiple aspects of the disorder such as (1) clinical aspect in terms of PANSS, (2) cognitive aspect such as emotion recognition (ER) and working memory (WM) / distractor filtering (DF) performance, and (3) neurobiology in terms of electrophysiology correlates of ER, WM and DF such as event related theta synchronization, resting state theta power, and network connectivity. Response prediction to (theta-burst) TB-rTMS will be the exploratory part of the study.

This is a Phase 3, multicenter, 52-week, outpatient, open-label extension (OLE) study to evaluate the long-term safety and tolerability of adjunctive KarXT in subjects with schizophrenia with an inadequate response to their current antipsychotic treatment who previously completed the treatment period (Visit 8/Day 42 ± 3) of ARISE Study (KAR-012). The primary objective of the study is to assess the long-term safety and tolerability of adjunctive KarXT (a fixed dose combination of xanomeline and trospium chloride twice daily [BID]) in subjects with schizophrenia. Additional exploratory objectives assess the efficacy of adjunctive KarXT at scheduled visits.

1.031 / 5.000 Çeviri sonuçları This research was planned to determine the effect of health protection and promotion program based on motivational interviewing based on Pender's Health Promotion Model on healthy lifestyle behaviors of individuals with schizophrenia. When the national and international literature is examined, it is known that there are descriptive studies on the physical health of individuals with mental disorders, and interventional intervention programs under the leadership of psychiatric nurses for the protection and development of the physical health of individuals with mental disorders are very limited. In this context, psychiatric nurses act as a bridge between mental and physical health for patients. It is thought that this study, which will be conducted to evaluate the healthy lifestyle behaviors of individuals with schizophrenia, of the Health Promotion Model and motivational interview-based health protection and promotion program will contribute to the literature, provide data for future studies, and be an applicable model for TRSMs.

To evaluate the safety and efficacy of Lurasidone initiated with 40mg and 80mg in treatment with acute phase patients with schizophrenia

The overall aim of this program of research is to improve the continuity of care for patients with serious mental illness (SMI) by supporting a safer and more efficient bridge from hospital to outpatient care using a mobile device-delivered app called Transition-FOCUS (tFOCUS), which has previously been tested in community samples. The purpose of the proposed project is to establish the effectiveness of our empirically-supported, multi-component mHealth intervention.

The primary objective of this grant is to develop and evaluate an Artificial Intelligence-based clinical training tool--CBTpro--to support high-quality skills training in CBT for psychosis (CBTp). CBTpro will provide a rapid means of scaling and sustaining high-quality CBTp in routine care settings across the US.

Cognitive impairment is well established in people with psychosis and is associated with cannabis use. The current study will investigate the neurobiological basis of cognitive change associated with 28-days of cannabis abstinence in people with psychosis and non-psychiatric controls with cannabis use. Participants will be randomized to a cannabis abstinent group or a non-abstinent control group and will undergo magnetic resonance imaging at baseline and following 28-days of abstinence. This study will help characterize the neuropathophysiological processes underlying cognitive dysfunction associated with cannabis use and its recovery which may guide the development of novel interventions for problematic cannabis use.

This study examines the feasibility and acceptability of a virtual tumor board for cancer and mental illness for patients with serious mental illness and a new cancer diagnosis. The study also examines the impact on patient care, psychiatric symptoms, and clinician self-efficacy in managing this population.

Wide ranging cognitive deficits are major drivers of functional decline and poor outcomes in people with schizophrenia (SZ) and bipolar disorder (BD). Medications do not target pathophysiological mechanisms thought to underlie these deficits. In the search for interventions targeting underlying cognitive impairment in SZ and BD, we look comprehensively beyond just the brain and to the potential role of dysfunctional systemic metabolism. Disrupted insulin and glucose metabolism are seen in medication-naïve first-episode SZ, suggesting that SZ itself, and not just the medications used to treat it, is associated with risk of Type 2 diabetes, cardiovascular morbidity and mortality, and more generally, accelerated aging. Even young people with SZ have increased risk of metabolic disease and cognitive deficits. Sadly, their life span is shortened by 15-20 years. BD is associated with similar but less severe disruptions in glucose and insulin metabolism and life expectancy. Although the human brain is 2% of the body's volume, it consumes over 20% of its energy, and accordingly, the brain is particularly vulnerable to the dysregulation of glucose metabolism seen in SZ and BD. While glucose is considered to be the brain's default fuel, ketones provide 27% more free energy and are a major source of energy for the brain. Ketones prevent or improve various age-associated diseases, and a ketogenic diet (70% fat, 20% protein, 10% carbohydrates) has been posited as an anti-aging and dementia antidote. The premise of the work is based on recent evidence that ketogenic diets improve dynamic neural network instability, related to cognitive deficits, aging, and Type 2 diabetes (Mujica-Parodi et al., Proc Natl Acad Sci U S A. 2020;117(11):6170-7.). The rigor of the work rests on findings of (1) poor cerebral glucose homeostasis in SZ and BD, (2) neural network instability in SZ and BD, and (3) direct effects of ketosis on network instability. Unknown is whether ketogenic diets can improve network instability in people with SZ and BD.
