Filter by:The main objective is to compare changes in information processing speed after 30 days of intervention in participants with a dysexecutive mild cognitive impairment (MCI) and receiving either cognitive stimulation by adapted visual exercises (Emeraude® software) or the broadcasting of a television program without cognitive stimulation. Secondary objectives are: - To compare, after 30 days of intervention, in participants with a dysexecutive MCI and receiving either cognitive stimulation by adapted visual exercises (Emeraude® software), or the broadcasting of a television program without cognitive stimulation : - changes in information processing speed of each subtest, - changes in cognitive performance, - changes in executive functions, - changes in walking performance. - To compare the quality of life, after 30 days of intervention, of participants with a dysexecutive MCI and receiving either cognitive stimulation by adapted visual exercises (Emeraude® software) or the broadcasting of a television program without cognitive stimulation. - In the "Intervention" group, to study correlations between changes in information processing speed index and the final level reached for each cognitive stimulation exercise.
Patients with gliomas often suffer from lower quality of life, and detrimental social interactions after diagnosis. Two cognitive processes are crucial for maintaining healthy social relationships and interacting with others: social cognition and language. Social cognition is the ability to recognize and process mental and emotional states and to react appropriately in social situations. Social cognition and language are separate cognitive functions that can be affected in different ways in patients with brain injury. Also, distinct cognitive measurement instruments are used to assess both processes. However, there appears to be a certain overlap between social cognition and language. Reacting adequately in social situations requires both verbal and non-verbal communication and to communicate feelings, thoughts and intentions, people often use language. That is, verbal communication is part of a symbolic system that makes social interaction possible. Therefore, language abilities seem to be important to social cognition. Research shows that language is frequently impaired in adult patients with gliomas. Importantly, recent evidence suggests that social cognition can also be impaired in this patient group. However, no studies have been conducted into the relationship between social cognition and language in patients with gliomas. Increasing knowledge on the overlap between both functions, more specifically the influence of language difficulties on social cognition, will improve diagnostic accuracy. Eventually, this will lead to better, tailor-made treatments for these problems that negatively affect daily functioning. Objective: The main research objective is to examine the influence of language impairments on different social cognition processes, i.e., emotion recognition, Theory of Mind (ToM) and affective empathy, in patients with (suspected) gliomas. Secondary objectives are 1) to determine if patients with gliomas show impairments in different aspects of social cognition, i.e. emotion recognition, ToM, empathy and self-awareness; 2) to assess specific language impairments by looking at item-level characteristics of language tasks (e.g., analyses of word properties of fluency tasks, errors during object naming or spontaneous speech), and 3) to determine which tumor characteristics (low- or high-grade, genetic mutation, tumor location) are associated with different aspects of language and social cognition.
Cancer is a frequent disease considering that one person out of three will be confronted with it in their lifetime. Cancer patients often express complaints related to cognitive impairment as an outcome of their oncological treatment. These cognitive disorders have a significant impact on the patient's and their carer's quality of life. Therefore, it appears necessary to have a reliable, quick and simple tool in order to detect cognitive impairment. The rationale of this study relies on 3 main points : - The cognitive complaint frequently reported by cancer patients - The difficulty in reliably demonstrating the cause of this complaint through conventional neuropsychological tests - The interest of cognitive processing speed as an indicator of cognitive dysfunction The primary objective of the study is to evaluate a potential variation of cognitive processing speed at the Saint-Louis Lille Battery (SSLIB) between the beginning and during (4 months after the beginning) the oncological treatment of adults with breast cancer or colon cancer.
COVID-19 has swept the world, and while some people may experience long-term cognitive decline as a result of infection, no effective treatment has been announced. The primary goal of this study was to determine the efficacy of hyperbaric oxygen therapy in patients with SARS-CoV-2 infection, as well as to assess the effect of hyperbaric oxygen therapy on brain function in patients with COVID-19-related cognitive decline. In this study, approximately 80 people were randomly assigned to either hyperbaric oxygen or regular oxygen therapy to compare the effects of these two treatments on disease.
Phase II, multi-centric, randomized, double-blinded, placebo-controlled, parallel design clinical trial to evaluate the safety, tolerability and efficacy of Donepezil in patients with Mild Cognitive Impairment in Parkinson's Disease (PD-MCI). A total of 120 patients with PD-MCI will be randomized to 12 months of oral Donepezil 10mg or matching placebo (1:1). Primary and co-primary efficacy endpoints are cognitive and functional cognitive scales: PD-CRS and PD-CFRS. Secondary efficacy endpoints include: cognitive tests evaluating attention, executive functions, language, memory and visuospatial domain; mood, anxiety, and apathy scales; questionnaires to evaluate quality of life; and subjective impression scales. Serum Neurofilament light chain, genetic screening of GBA, ApoE and MAPT, and Magnetic Resonance Imaging will be performed in a subset of these patients. The study will be conducted in 20 different centers around Spain. The Movement Disorders Unit of the Neurology Department at Sant Pau Hospital (Barcelona, Spain) will be the coordinating center.
Hypertension is an risk factor for cognitive impairment. The primary objective of this study is to evaluate the efficacy of 12-week computerized cognitive training in people with hypertension and mild cognitive impairment. The researchers will further investigate the long-term effects of cognitive training by prolonging the intervention for 24 weeks among a randomly selected sub-group.
Mild cognitive impairment (MCI) represents a transitional stage between healthy aging and dementia, and affects more than 15% of the population over the age of 60 in China. About 15% patients with MCI could progress into dementia after two years and about one-third develop into dementia within five years, which will lead to suffering, as well as staggering economic and care burden. So, exploring the predicting biomarkers from MCI to dementia to identify and delay progression to dementia at an early stage is of great social and clinical significance. Some reports based on a single neural biomarker suggest that risk models can predict the conversion of MCI to dementia, but no widely recognized prediction models basing on multiple complex markers have been used in clinical practice. The objectives of this study are to outline the spectrum of MCI transforming into dementia through a 5-year prospective longitudinal cohort study; Secondly, screening biomarkers for MCI transmit to dementia are based on clinical symptoms, neuropsychology, neuroimaging, neuroelectrophysiology, and humoral markers tests data.
To evaluate the effectiveness of a daily cognition training programme versus a traditional cognitive stimulation programme in cognitively unimpaired older adults on cognitive function, emotional state, frailty and functionality.
To investigate the impact of rTMS on the incidence of perioperative neurocognitive disorders in patients after after cardiac surgerysurgery. To explore the underlying mechanisms behind the efficacy.
This study is a prospective observational study, which involves a cohort of 2000 all-sex and all-ethnic people aged 60 years and above with permanent residence in Tianma area, SheMountain Town, Songjiang District (suburban area), Shanghai. Demographic information, neuropsychiatric scale, peripheral blood, APOE genotype, brain MRI, speech information, AV45-PET, FDG-PET, Tau-PET, GLP-1R PET, and cholinergic receptor probe (ASEM) PET were collected and analyzed. Follow-up visits were performed twice a year for 4 visits, and neuropsychiatric scales and biological samples were collected at each follow-up visit to construct a diagnostic model for patients with mild cognitive impairment, or Alzheimer's disease, as well as a predictive model for the progression of cognitive impairment.
