This study will test whether consuming blueberry powder 20g/d for 24 weeks can improve memory and other cognitive function and alter serum biomarkers of brain injury among older adults.
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.
Mild cognitive impairment (MCI) is a syndrome that occurs in the preclinical stage of Alzheimer, and early intervention can be effective in preventing Alzheimer, but further research is needed on intervention methods. In order to identify interventions that are more suitable for Chinese characteristics and to investigate the effects of a motor-cognitive intervention on the cognitive function of older adults with MCI, investigators screened 103 community-dwelling older adults with MCI aged 65 years and older in Qingdao, Shandong, China, and divided them into an intervention group and a control group, and administered a motor-cognitive intervention to the intervention group for 12 weeks. Investigators assessed the cognitive abilities of MCI participants using the Mini-Mental State Examination (MMSE) and Montreal Cognitive Assessment (MoCA). There were no demographic differences between the intervention and control groups. Investigators found that the cognitive abilities of the intervention group were significantly improved at the end of the intervention as well as at the end of the follow-up compared to the control group. The results of the current study suggest that the motor-cognitive intervention investigators used significantly improved cognitive function in older adults with MCI and was easy for older adults to master, and that it was a good intervention for cognitive function in older adults with MCI in the Chinese community.
Mild traumatic brain injury (mTBI) often causes persistent motor and cognitive deficits in children resulting in functional limitations. We are testing a brain stimulation method along with evaluating objective tools to help record and restore communication among affected brain areas, which will facilitate recovery in youth after mTBI.
The aim is to evaluate the presence of mild cognitive impairment (MCI) in patients with inflammatory bowel disease (IBD). This will be done by cognitive tests. Along them, screening for depression, anxiety and stress will be done. A blood sample for determining serum values of homocysteine, protein S100-B, amyloid and BDNF will be stored. Patients will be followed-up for 2 years.
The goal of this observational study is to compare cerebral perfusion patterns with pseudo-continuous arterial spin labeling (pCASL) and brain metabolism patterns with fluorodeoxyglucose-position emission tomography (FDG-PET) in patients with mild cognitive impairment (MCI) and subjective cognitive decline (SCD). The main questions it aims to answer are: - Do pCASL sequences identify hypoperfusion patterns that correlate well with FDG-PET hypometabolic patterns? - Are there differences in this correlation in terms of cerebrospinal fluid (CSF) profiles? - Can hypoperfusion patterns in pCASL predict conversion to dementia? Participants will undergo brain 3 Tesla magnetic resonance imaging (MRI), FDG-PET, lumbal puncture and blood collection to analyze amyloid beta and tau, yearly detailed neuropsychological tests for three years.
Obesity and glucose intolerance or overt diabetes are increasing at an alarming rate in the population, and are bound to become a public health issue and a major cause of disability, loss of independence and high social costs in the near future. A large body of evidence has in recent years highlighted, among the negative effects of overnutrition and glucose dysmetabolism, also an acceleration of cognitive decline and of brain senescence, through cellular (vascular, neuronal, or both) and molecular mechanisms still incompletely clarified. Understanding how overweight and impaired glucose homeostasis negatively affect brain function represents both a major scientific challenge and an avenue to early detection and possibly prevention of this invalidating complication. The aim of this project is to obtain neuronal progenitor-like cells from skin fibroblasts in order to correlate patient-specific metabolism to adult neural stem cell (NSC) and neuronal function in vitro.
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.
Cognitive frailty, characterized by the coexistence of physical frailty and cognitive impairment, is a robust indicator of cognitive decline. Recognizing its significance, the International Association of Gerontology and Geriatrics and the International Academy on Nutrition and Aging have advocated for the use of cognitive frailty assessment as a means of monitoring the progression of mild cognitive impairment towards debilitating conditions like dementia, Alzheimer's disease, and loss of independence. Despite the clear need, a practical and remotely accessible tool for measuring cognitive frailty is currently lacking, especially within the context of telehealth visits. With telehealth video-conferencing becoming increasingly popular, accepted by healthcare payers, and preferred by older adults who may face difficulties traveling to a clinic, there is a pressing need for a software-based solution for remote cognitive frailty assessment that can be easily integrated into existing telehealth systems. This study proposes designing and validating a video-based solution to remotely monitor cognitive-frailty in older adults.
