Filter by:Approximately 1% of the general population will be affected by schizophrenia over the course of their lives, with life expectancy being reduced by 20 years on average and quality of life being severely diminished in affected individuals. One third of patients suffering from schizophrenia will evolve towards a resistant form of the disease, amongst which many will suffer from auditory-verbal hallucinations (AVH) that current therapeutic approaches struggle to alleviate. Previous work from our team has demonstrated the possibility of robustly inferring the periods of occurrence of AVH from fMRI data, paving the way for the development of a closed-loop neuromodulation system comprised of an electrode array positioned in Broca's area, which would detect AVH in real time, and effector electrodes which would stimulate the temporo-parietal cortex to interrupt them. The aim of this project is to assess the feasibility of this system. To do so, we will first test the ability of transcranial magnetic stimulation of the "continuous theta burst" (cTBS) type, applied at the time of AVH onset, to reduce their duration and intensity, and assess whether this is associated with therapeutic response to the current gold standard rTMS protocol for AVH reduction through neuroplasticity induction. Demonstrating the feasibility of acute suppression of AVH by cortical neurostimulation is an essential element in the feasibility of a closed-loop reactive neuromodulation system. The research project comprises two phases: -Phase 1: randomized controlled clinical trial (1 weekly session per patient over 12 weeks: 6 active stimulation sessions and 6 sham sessions) evaluating the phasic effects of rTMS on AVHs as they appear during the sessions. Phase 2: open-label study offering patients a routine rTMS protocol which has demonstrated its effects on AVH (10 TMS sessions over one workweek - twice daily with 1-hour intervals, MULTIMODHAL study, NCT01373866).
In the fight against stigma, the focus should be on the education of individuals diagnosed with mental illness. Psychoeducation has an important place in the treatment and rehabilitation of mental health problems. Psychoeducation is necessary for early recognition of signs and symptoms of diseases, ensuring compliance with treatment, improving coping skills, as well as combating stigma, preventing internalized stigma, and counteracting social stigma. If individuals with mental disorders have adequate knowledge about the causes of stigma, they may be less prone to internalized stigma.
Patients with schizophrenia spectrum disorder (SSD) will be exposed to active repetitive transcranial magnetic stimulation (rTMS) from H coil for improving white matter integrity.
This project is a double blind randomized clinical trials that examines the efficacy of cerebellar non invasive stimulation for apathy improvement in patients with schizophrenia
Although antipsychotic is effective for schizophrenia, however, still certain proportion of patients were not responsive to treatment. Treatment resistant schizophrenia (TRS) is accompanied by function decline and heavy burden. In recent decades, the biological mechanism of schizophrenia extended from dopamine theory to the role of glutamate system. This shift could be an alternative pathway to developing the treatment of TRS. Sodium benzoate (SB) could be an option as a glutamatergic agent for the patients with TRS. However, most evidence of SB is for treating patients with schizophrenia and other mental disorders but the evidence for treating patients with TRS is scarce. To predict the treatment response of SB will be an urgent topic in the future. Little is known about the precise medicine for treating patients with TRS. The present project will extend our pilot randomized clinical trial on SB for TRS. A total of 90 patients with TRS will be enrolled from three centers and will be assigned to 8 weeks of treatment with SB or placebo (2:1). A comprehensive battery of potential markers will be employed, including 1H- magnetic resonance spectroscopy (MRS), brain functional connectivity, genotyping, immune biomarkers, cognitive function, and clinical characteristics. The efficacy of SB on TRS will be confirmed in this project. Predictors for treatment response will be identified. Artificial intelligence algorithms will be used for probing the feasibility of precision medicine.
Schizophrenia (SZ) is a broad clinical entity characterized by different subjective symptoms,behavioural signs, and disease course. Research has pointed to numerous biological indicators tentatively associated with neurocognitive dysfunction, brain structural and neurochemical alterations. Cognitive deficits occur as early as the prodromal phase of the illness and significantly determine its outcome. Pathophysiologically, SZ is regarded as a disconnectome disorder in which frontal and temporal brain regions are functionally disconnected, which contributes substantially to the development of cognitive dysfunction. Impaired connectivity is related to synaptic (microconnectivity) and myelin (macroconnectivity) plasticity. With design-based stereology, a decreased number of oligodendrocytes (OLs) in the CA4 hippocampal subregion as the basis for disturbed myelination and impaired cognition, but also a decrease in the prefrontal cortex were observed. Animal studies demonstrated that clemastine enhances remyelination by increasing the differentiation of oligodendrocyte precursor cells (OPCs) and showed that aerobic exercise increases the rate of remyelination and proliferation of OPCs; this clinically meaningful effect of aerobic exercise is stronger in combination with clemastine. Furthermore, aerobic exercise improves everyday functioning, measured by the Global Assessment of Functioning (GAF) scale, and cognitive dysfunction in SZ and increases hippocampal volume, especially the volume in the hippocampal CA4 subregion. This regional volume change correlates negatively with global and cell-specific polygenic risk scores (PRSs), indicating that OPCs are involved in the genetic risk mechanisms and disturbed plasticity underlying SZ. In patients with multiple sclerosis, 90 days' administration of clemastine fumarate 10.72 mg/day, corresponding to clemastine 8 mg/day, significantly decreased the P100 latency delay of visual evoked potentials (VEPs) as a sign of myelin repair. In a bicentric, randomized, double-blind, controlled phase IIb clinical trial with a 2-arm parallel group design in patients with SZ, the study will compare the effects of aerobic exercise training plus clemastine vs. aerobic exercise training plus placebo over a period of 3 months on 1) everyday functioning and 2) working memory as primary outcomes.
This study will determine the efficacy of hippotherapy (horseback-riding) program, as an adjuvant to standard psychiatric treatment, on the outcomes of patients with schizophrenia. A randomized controlled trial is conducted in a Community Mental Health Center. All participants are randomized into two groups (experimental and control groups) using blocked randomization. All participants received the standard psychiatric treatment, while the experimental group is additionally provided with a 16-session hippotherapy program for 8 weeks. All participants will be evaluated using the Positive and Negative Syndrome Scale, State-Trait Anxiety Inventory, Quality of Life Scale, UCLA Loneliness Scale at both baseline and after the intervention.
The study is to evaluate the safety, tolerability, and PK characteristics following single administration of HS-10509 in healthy adults, and multiple administrations of HS-10509 in patients with schizophrenia. Participants will have HS-10509 tablets or placebo once in the single ascending dose (SAD) part or once daily for 28 days in the multiple ascending dose (MAD) part.
Adults with serious mental illnesses (such as schizophrenia and schizoaffective disorders) often experience a range of cognitive difficulties (such as memory, problem solving difficulties) that affect their ability to lead meaningful life roles. Cognitive remediation is an intervention to address cognitive difficulties in this group of mental health service users. Its implementation in less well-resourced community-based settings is less well-studied. Therefore, the aims of the study are: - To investigate the effects of cognitive remediation on various cognitive skills (such as attention, memory, problem-solving, facial expression recognition, taking others' perspectives etc), for participants with schizophrenia or schizoaffective disorders in community mental health settings. - To investigate if factors such as participants' motivation for engagement and social interaction can affect changes in cognitive skills and functional ability. Participants in the treatment group will attend computer-based cognitive exercises to improve their cognitive skills. They will also participate in group sessions facilitated by therapists to learn how to utilize strategies learned from the computer sessions in their daily lives. Participants in the control group will attend the usual rehabilitation activities in their respective community-based psychiatric rehabilitation centers. This research study will compare the differences in their cognitive performance, functional ability and recovery immediately after the intervention and 8 weeks later.
This project aims to introduce a new psychoeducation program that helps individuals with schizophrenia to recover subjectively. The program's effectiveness will be evaluated through a randomized controlled research design. The goal is not only to emphasize clinical recovery but also to highlight the importance of individual recovery and promote its implementation. In this context, the following hypotheses have been formulated. Research Question: 1) Does recovery-based psychoeducation have an impact on the subjective recovery level in individuals diagnosed with schizophrenia in remission? Hypotheses: H0a: Recovery-based psychoeducation does not affect the subjective recovery level in individuals diagnosed with schizophrenia in remission. H0b: Recovery-based psychoeducation does not effect on psychological resilience in individuals diagnosed with schizophrenia in remission. H0c: Recovery-based psychoeducation does not effect on hope in individuals diagnosed with schizophrenia in remission. H1a: Recovery-based psychoeducation affects the subjective recovery level in individuals diagnosed with schizophrenia in remission. H1b: Recovery-based psychoeducation has an effect on psychological resilience in individuals diagnosed with schizophrenia in remission. H1c: Recovery-based psychoeducation has an effect on hope in individuals diagnosed with schizophrenia in remission.
