Filter by:Parkinson's disease (PD) is a progressive neurological disorder characterized by motor and non-motor symptoms such as rigidity, bradykinesia, resting tremor, cognitive and autonomic dysfunctions, gait and balance difficulties. The impairment of gait, balance and cognitive performances is partially responsive to dopaminergic medications. This emphasizes the importance of non-pharmacological interventions for people with PD (pwPD). Intensive multidisciplinary motor and cognitive rehabilitation has been proposed as a complementary and effective treatment for managing pwPD. Several structural and physiological mechanisms have been suggested to underpin exercise-induced neuroplastic changes in PD, such as enhanced synaptic strength and preservation of dopamine neurons. To date, studies on brain changes induced by motor and cognitive exercises in pwPD have been small-scaled and uncontrolled. Identifying accessible and measurable biomarkers for monitoring the events induced by intensive motor and cognitive rehabilitation program would help in testing the treatment effectiveness and would allow personalization of rehabilitation strategies by predicting patients' responsiveness. Based on validated clinical assessments of intensive multidisciplinary rehabilitation treatment, the project will test the ability of a new set of biomarkers to evaluate rehabilitative outcomes in a cohort of people with PD.
This multicentre study, with a randomised controlled repeated measures experimental design, will be conducted in several Portuguese institutions, which provide care and supportive services for older adults diagnosed with mild or moderate Alzheimer's disease (AD), with an aim to assess the effect of individual cognitive stimulation (CS) on memory and executive functioning. Participants in the intervention group will attend 24 individual CS sessions, twice weekly for 12 weeks. Participants in the control group will complete their usual routines without any activity restrictions.
This projects studies the role of mindfulness training (MT) to improve self-care among patients with heart failure and cognitive impairment.
In this study, the investigators implement FDG-PET imaging for clients in the Geriatric Psychiatry department at The Royal Ottawa Hospital (ROH) and evaluate the impact of this advanced imaging technique on client care. This study is intended to provide supporting evidence for the continued use of FDG-PET imaging at the ROH BIC as a diagnostic support for the differential diagnosis of unclear dementia.
The randomized controlled trial will be conducted to evaluate the effectiveness of a Multi-domain Tai Chi Digital Therapy for treating the individuals suffering from the long term COVID-19 syndrome (Long COVID).
OptiCogs Online is a complex multicomponent intervention comprising of cognitive, physical activity and educational components.
The study utilizes investigational software, the SPARK Test, with an FDA-cleared electroencephalography (EEG) amplifier and EEG cap to collect and then analyze patient EEG data.
Biliary atresia is the most severe form of cholestatic liver disease. The children have high morbidity and mortality and get devastating pruritus and fatigue, failure to thrive, progressive hepatic failure and impaired neurodevelopment. The etiology is mostly unknown. More than half need a new liver from a living or deceased donor during childhood. However, correct timing of the transplantation is extremely difficult because of lack of consensus based on clinical assessment tools. All though the incidence is low, the cost of this disease is tremendous from both a clinical and human perspective. So far, protocolized neurodevelopment tests, genetic profiling, precise malnutrition evaluation based on clinical appearance, biochemical markers and brain MRI-scans, body composition, immunological function, level of physical activity and optimal time of transplantation in cholestatic children are unknown. The aim is to determine risk factors for neurocognitive impairment in children suffering from severe cholestasis in order to determine optimal time for liver transplantation from a brain perspective. In a prospective study, the investigators will investigate risk factors related to brain-, heart-, gut- and immunological function in the Danish cohort. This cohort consists of 75 children aged 0-18 years. In addition, 30 aged and gender matched healthy and 20 tetra fallot children will serve as control groups. The children will undergo extensive and advanced liver function evaluation, genetic profiling, nutrition and immunological status, neuro-imaging and neurocognitive evaluation at time of diagnose, 2 years of age, pre-school, pre-teenage, and teenage. In case of a liver transplantation, additional neuro-cognitive tests will be performed
The aim of this multicenter, cross-sectional, observational flash mob study is to investigate the prevalence of cognitive impairment in hospitalized elderly aged 65 years or older, and the recognition of cognitive impairment by healthcare professionals.
After almost 2 years of pandemic, the consequences of the post-COVID syndrome, or PASC (Post Acute-Sequelae of Sars-CoV-2), have become a major challenge in the management of affected patients, generating costs for health services. and insecurity regarding treatments for the sequelae, given the complex and still poorly understood pathophysiology of COVID-19. This troubling scenario raises important questions about the impact of COVID-19 on central nervous system sequelae, including the risk of cognitive decline in old age and progression to dementia. Therefore, studies that propose the possibility of treatment for this new clinical condition and that are free from systemic side effects, such as transcranial direct current stimulation (tDCS) and cognitive treatment, are extremely important in the face of this scenario. In addition, the evaluation of the neural mechanisms underlying the cognitive alterations of the PASC syndrome and after the treatment using multimodal magnetic resonance imaging (MRI) becomes relevant in view of the lack of studies related to the topic. Therefore, the objective of this double-blind randomized clinical trial is to assess whether tDCS associated with cognitive training can improve symptoms in patients with persistent cognitive deficits that started between 1 and 6 months after the resolution of acute COVID-19 infection (PASC) compared to the sham (placebo) group, in addition to exploring the structural, microstructural, functional and modeled electric field changes associated with cognitive alterations due to PASC syndrome and tDCS combined with cognitive treatment. 60 patients aged between 18 and 70 years and with a positive diagnosis of mild to moderate COVID-19 in the last 6 months in relation to the time of entry into the study will be recruited. All of them will be pre-screened online and in person to confirm the cognitive dysfunction associated with PASC.
