Filter by:Disturbances in the sense of self and time could play an important role in the development of psychotic symptoms. Previous work has shown that patients have difficulty preparing to process information on the scale of a second, but are abnormally disturbed by slightly asynchronous information on the millisecond scale. In both cases, the anomalies could explain the patients' unusual experience of time. The hypothesis in neurotypical patients is that small delays or asynchronies asynchronies are treated as irrelevant information and ignored and ignored, whereas in patients suffering from schizophrenia they would disrupt the flow of time. This hypothesis is tested with a new visual illusion.
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).
A multicenter, randomized, double-blind, placebo-controlled, dose-increasing phase Ib/II clinical trial to evaluate the safety, tolerance and pharmacokinetic characteristics of JX11502MA capsules administered multiple times in patients with schizophrenia
Schizophrenia patients commonly present with persistent negative symptoms which remain the main reason for dysfunction after recovery from an acute episode of psychotic symptoms. Negative symptoms in schizophrenia exact significant burden with no effective pharmacological or behavior treatment options thus far. Neuromodulatory modalities present a novel and alternative treatment approach and recent trials have shown preliminary evidence for the efficacy of intermittent Theta Burst Stimulation (iTBS) to treat negative symptoms in schizophrenia. In this study, we aim to examine the effectiveness of an accelerated iTBS treatment protocol as an augmentation treatment regime for patient in rehabilitation care with persistent negative symptoms. We propose a pragmatic, open label and single arm clinical trial. Forty patients with diagnosis of schizophrenia, who had been stabilized from psychotic symptoms and currently suffering from dominant negative symptoms will be recruited and undergo accelerated iTBS treatment for 5 consecutive sessions each day for 5 working days. Participants will be followed up immediately, 1 month and 3 months after the end of treatment. Clinical assessment includes, BNSS, The Brief Negative Symptom Scale; SANS, Scale for the assessment of negative symptoms; SAPS, Scale for the assessment of positive symptoms; PANSS, Positive and Negative Symptoms Scale; MoCA, Montreal Cognitive Assessment scale; CDSS, Calgary Depression Scale for Schizophrenia: SDS, Sheehans' disability scale and EQ-5D. The primary endpoint of the trial is the change of negative symptoms as assessed by PANSS, negative symptoms subscale immediately after the treatment. This study will determine whether accelerated iTBS is effective to be delivered as an augmentation therapy for patients with persistent negative symptoms. The optimal treatment system for this population can be immediately translated to clinical practice and benefit patients in need.
The study is a randomized, double-blind, parallel-arm, sham-controlled trial that aims to compare the effects of transcranial direct current stimulation (tDCS) versus sham stimulation on inflammatory markers (IL-6 and TNF-alpha) and clinical outcomes (PANSS, AHRS, CGI-SCH, GAF) in patients with chronic schizophrenia over 10 days of treatment. The primary objective is to assess changes in IL-6 levels, while secondary objectives include evaluating changes in TNF-alpha, symptom scales, and adverse events. The study will be conducted at the psychiatry department of AIIMS Bhubaneswar, with 60 patients aged 18-60 years with moderate-to-severe schizophrenia symptoms randomized to receive either active tDCS (cathode over left temporo-parietal junction, anode over left dorsolateral prefrontal cortex) or sham stimulation. The researchers hope to elucidate the potential immunomodulatory effects of tDCS and its impact on symptoms in chronic schizophrenia, which may lead to more targeted, multifaceted interventions to improve patient outcomes.
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.
The goal of this study is to evaluate the effectiveness of an behavioral activation intervention to increase meaningful activity and community participation for people with serious mental illness. The overall objective of this study is to increase engagement in meaningful activities and community participation. The objectives of the project are as follows: 1. To determine if the intervention leads to increases the frequency and variety of activities. 2. To determine if the intervention leads to increases in community mobility. 3. To determine which demographic and environmental factors and mechanisms of action impact the effectiveness of the intervention. 4. To determine if the the intervention leads to an improvement in overall well-being (e.g., improved quality of life). Participants will be asked to attend a 2-hour weekly online session for 10 weeks and then a 1-hour online monthly session for a 3 month maintenance period. For data collection, participants will also be asked to: 1. Complete three, approximately 1-hour interviews at baseline, after the 10 week intervention, and again at the end of the maintenance period; 2. Carry a mobile phone with a global positioning system app to track their movements outside their home for 2 weeks at a time, at three separate times (e.g., baseline, after the intervention, and at the end of the maintenance period); and 3. Complete a 15 minute weekly interviews for 26 weeks about their daily activities and participation. The study will enroll 52 participants split into 4 cohorts of 13. The study will use a multiple baseline design and, as such, all participants will receive the intervention and there is no control group.
