Filter by:This study aims to investigate changes in functional connectivity over a four week treatment course with intermittent theta burst stimulation (iTBS) in patients with major depressive disorder (MDD). To this end, seven weekly resting-state fMRI (rs-fMRI) scans at 7 tesla (7T) will precede, accompany and follow the iTBS treatment course. By obtaining several samples of the modulatory effects of iTBS on functional connectivity networks and simultaneous measurements of the depressive symptoms it will be possible to assess the time course of changes in connectivity across different networks, and to assess the overall relationship between the network modulation and the antidepressant effects of the treatment over time.
Studies have shown that children with Attention Deficit Hyperactivity Disorder (ADHD) and emotional dysregulation are characterized by high severity of ADHD, comorbid behavior disorders and increased risk of chronic difficulties. New studies have shown promising results by focusing on improving emotional regulation. We lack knowledge about differences in symptom patterns, stability of symptoms over time, comorbid disorders, neurocognitive functions, knowledge and regulation of emotions, psychosocial risk factors and reactions to stress. Children 6 to 12 years admitted to specialist and diagnosed with ADHD will be recruited. ADHD children with and without emotional dysregulation defined as fullfilling the criteria for the diagnosis Disruptive Mood Dysregulation Disorder (DMDD) with regard to differences in symptom patterns, stability of symptoms over time, comorbid disorders, neurocognitive functions, knowledge and regulation of emotions, psychosocial risk factors and reactions to stress..
Anxiety and depression are normally associated with inflammation reactions and interleukin (IL) related pathways are most evidently involved. IL-17A (interleukin 17A) induces psoriasis-like inflammation and depression-like behaviors in animals and can be relieved by using IL-17A antibody. Also, human association studies found that IL-17A and certain downstream ILs are associated with the severity of anxiety. IL-17A is a sentinel cytokine. On binding with interleukin 17A receptor (IL-17RA) and interleukin 17C receptor (IL-27RC), it induces signaling cascades via nuclear factor kappa-light-chain-enhancer of activated B cells (NFκB), P38 mitogen-activated protein kinases (p38MAPK) and CCAAT-enhancer-binding proteins (C/EBPs) knots, and stimulates subsequent cell secretions of cytokines and chemokines. Cyanidin 3-O-glucoside, the main anthocyanin component of mulberry, competes with IL-17A to bind its receptors and inhibits subsequent downstream cascades. The investigators plan to use a single-blinded randomized controlled trial to evaluate the auxiliary effect of mulberry juice in general anxiety disorder, including differences in psychiatric symptoms and levels of IL-related markers between the experimental and control groups, and contribution of IL-related genes in the auxiliary effect.
The aim of this trial is to investigate the efficacy of left DLPFC iTBS in a population of alcohol use disorder patients, compared with the sham iTBS. Moreover, this trial will conduct follow-up assessments to evaluate whether its efficacy can sustain for a long time if it is effective.
The aim of this study is the efficacy of a docosahexaenoic acid (DHA)-rich dietary supplement in improving key dementia-related mechanisms and cognitive function in older people at risk for dementia. This is a randomized placebo-controlled, 24 weeks, phase 2 study of Omega 3 in people with increased risk of dementia. The aim is to explore the effects of DHA on cognitive performance (CERAD 10 word memory tests, TMT A/B, Stroop Color-Word, FAS, VOSP silhouettes, Cantab-test (RT, PAL, SWT)), biological markers (blood: CRP, NLF, TNF-alpha, MCI-1, PBMC Abeta middomain, Omega-3-index, IL, CSF: NLF, sTREM2, Ab 1-42, total and -phospho-tau) and imaging (MRI: standard structural DDI protocol including Freesurfer and WML measurements, DTI and ASL).
Implementation of 'NAVIGATE' in Ontario aims to help youth and emerging adults suffering from a first episode of psychosis. Although Ontario already has early psychosis intervention programs, the team's recent work has identified major challenges of delivering coordinated care, particularly those elements of care that enhance recovery. These challenges also exist nationally and internationally. By building on the already existing early psychosis intervention community of practice through the Early Psychosis Intervention Ontario Network, the investigators will implement NAVIGATE with the help of CAMH's Provincial System Support Program facilitators. The use of tele-videoconferencing through ECHO Mental Health Ontario and ECHO processes and protocols provide us with an opportunity to ensure sustainability. Using health administrative data held at the Institute for Clinical Evaluative Sciences (ICES), the investigators can examine system-level outcomes, including hospitalizations, emergency department visits, and outpatient physician visits of youth and emerging adults suffering from a first episode psychosis who are treated with NAVIGATE compared with those treated in early psychosis intervention programs without NAVIGATE and those who are not treated in early psychosis intervention programs. In addition, the investigators can also evaluate health care costs. Prior to initiating this project, the investigators obtained the input of youth and emerging adults with a first episode psychosis and family members. The investigators will also continue to measure engagement across the study. Hypotheses: 1. Following the implementation of NAVIGATE, program fidelity (i.e. adaptability) to the Ontario early psychosis intervention standard will improve. 2. Compared to patients not receiving NAVIGATE, those who receive NAVIGATE through this implementation study will have fewer days in hospital, fewer emergency department visits, fewer suicide attempts, lower mortality, and lower healthcare costs. 3. Improvements in functioning and symptoms will be comparable to the RAISE study (an earlier study assessing NAVIGATE); improvement may be influenced by demographic, socio-economic, geographic, and clinical factors. 4. The project's engagement approach will demonstrate that the investigators used the full range of patient engagement based on objectively assessed engagement metrics.
To investigate the efficacy and acceptability of a guided internet delivered transdiagnostic intervention, targeting mild to moderate clinical symptoms of anxiety and depression and emphasizing the changes taking place at the level of the structures of the self.
Cerebral palsy (CP) is the most common cause of child disability. Nearly 40% of PC children suffer from sleep disorders, which are not routinely screened. The neuro-cognitive, physical and environmental morbidity of sleep disorders should require their diagnosis and management. Limited access to the reference exam (polysomnography or PSG) delays the diagnosis and only allows screening of these disorders for a limited number of PC children. The hypothesis of our study is that connected technologies could optimize screening for sleep disorders in PC children by selecting children requiring PSG exploration and specific management.
Preliminary clinical evidence suggests that Service Members with symptoms of post-traumatic stress disorder (PTSD) or Post Traumatic Stress (PTS) who participate in the Service Dog Training Program (SDTP) report improved physical and psychological outcomes, including those with overlapping symptoms associated with traumatic brain injury (TBI) and post-concussion symptoms (PCS). This study intends to examine the psychological, social, and biological effects of learning how to train a future service dog combined with standard of care for individuals with symptoms of Post-Traumatic Stress (PTS), including those with overlapping TBI and persistent Post-Concussive Symptoms (PCS). Biological, social, and behavioral measures will be collected throughout study participation.
The purpose of this study is to evaluate the Computerized Exercise to Alter Stimulant Approach Responses (CEASAR), a novel stimulant use cessation intervention, for clients currently enrolled in a treatment centre for mental health and addiction. The investigators plan to conduct a randomized, single-blind controlled trial involving inpatients presenting with concurrent disorders to test the impact of this novel computerized intervention. This pilot study will be conducted at the Burnaby Centre for Mental Health and Addiction (BCMHA) in Burnaby, BC, Canada.
