Active clinical trials for "Cognitive Dysfunction"

Based on research showing that cognitive-motor training programs help improve cognition in older adults with mild cognitive impairment, this program uses an interactive system to combine cognitive training with exercise. The interactive system consists of wearable sensors and has the advantage of cognitive training without space constraints, and the cognitive training program consists of a total of five developed cognitive training games. The program is expected to improve the cognitive abilities of the elderly and improve their physical abilities.

Due to demographic changes that have resulted in an aging population, the role of caregiver of an older adult has become very important in recent years. While numerous programs have been designed to lighten the caregiver's physical and emotional burden, fewer programs train caregivers to improve skills and level of independence in the person they care for. The objectives of this research study were to assess the benefits of a caregiver training program on the cognitive and functional status of older adults, as well as to compare the effects of this program according to type of caregiver (professional caregiver vs. family caregiver). Methods: The sample was composed of 160 older adults: a) 100 received care from caregivers who had taken the training program (treatment group), of which 60 were professional caregivers and 40 were family caregivers; and b) 60 received care from caregivers who had not taken the program (control group). In order to evaluate program effects on cognitive and functional status, we used both direct measures (MMSE, CAPE and EuroQol) and caregiver reports (Barthel and RMPBC).

Age-related cognitive impairment is a wide phenomenon. Mild cognitive impairment is a transitional stage between Dementia and normal cognition.Mild cognitive impairment (MCI) is a syndrome that has been recognized in older adults and it has become a topic of a major focus on clinical care and research. In people with this condition, there are cognitive deficits and these have adverse effects on activities of daily living . These patients cannot recognize their impairment. Mild cognitive impairment is a risk factor for dementia.

Manipulation of the gut microbiota through dietary modification affects brain function, with improvement in patients with cognitive disorders. Combined effect of nutritional intervention with Mediterranean diet and probiotics with potentially healthy growth of germ, affect the evolution of mild cognitive impairment, by the modulation of components related with the axis microbiota-gut-brain: neuropeptides, short-chain fatty acids, markers for oxidative stress and inflammation.

Over 700,000 Canadians are affected by dementia costing the health care system approximately $10 billion/year. Due to COVID-19, the government has urged individuals over the age of 70 to stay home, putting this population at risk of social isolation. Older adults with mild cognitive impairments (MCIs), dementia, and their caregivers are at an even higher risk of becoming stressed, anxious, and agitated while in lockdown. Unsurprisingly, caregiver burden is extremely common, and often precedes institutionalization of the patient, as the demands of the illness begin to exceed that which the caregiver can sustainably provide. Since social distancing measures have shut down activities and support groups for these individuals, there is an urgent need for scalable, cost-effective, non-pharmacological interventions that can be delivered remotely to improve stress and loneliness. Yoga may be a viable therapeutic modality to address the psychological challenges associated with dementia in patients and caregivers, as it has been shown to decrease stress and improve anxiety and depressive symptoms in various populations. For this reason, the investigators are conducting a randomized controlled trial (RCT) to assess the efficacy of an 8-week virtual chair yoga program to improve stress, psychological symptoms, and caregiver burden. This virtual chair yoga study will engage both older adults with dementia/MCI and caregivers (n=40-60 participants) during COVID-19, which is consistent with the need for decreasing costs and increasing accessibility of novel health interventions during and beyond the pandemic. The investigators will evaluate the effect of this program on stress, loneliness, and mental health related outcomes such as fear of COVID-19, depression, anxiety, and caregiver burden compared to a waitlist control group. There will also be a qualitative component in the form of semi-structured interviews. All quantitative outcomes will be assessed before the program starts and post-intervention and qualitative outcomes will be assessed post-intervention. Participants will be randomly assigned to the treatment group (virtual chair yoga 1 hour per week on Zoom) or the waitlist control group. The investigators hypothesize that after the 8-week yoga program, older adults and caregivers will report lower stress, loneliness, depression, anxiety, fear of COVID-19, and caregiver burden. Results will be available late-2021.

Postoperative cognitive dysfunction (POCD) is a common postoperative complication in patients aged 65 and over, which refers to cognitive function changes such as memory decline and attention deficit after anesthesia and surgery. In severe cases, personality changes and social behavior decline may also occur, resulting in irreversible cognitive impairment.Previous studies have suggested that cognitive dysfunction after general anesthesia is linked to a genetic disorder of the body clock.Exosomes are cellular forms of cellular microvesicles containing complex RNA and proteins.Exosomes can mediate the expression of genes in the late transcriptional period of the clock system, and directly or indirectly participate in the negative regulation of rhythm expression of minute control genes, playing an important role in the intercellular circadian rhythm information output pathway.Rhythm disorders in the core biological clock system of urinary exosomes and the clock control genes related to kidney can early indicate circadian rhythm changes in the core biological clock system.The sorting and detection of urinary exosome clock information materials in patients has the advantages of easy access, continuous monitoring, early diagnosis and less damage, making urinary exosome a biomarker for the diagnosis and monitoring of circadian rhythm of a good kidney biological clock system.

This study is a multicenter, double blind, randomized, placebo-controlled study to evaluate the safety, tolerability and immunogenicity of different doses, regimens and combinations of Tau targeted vaccines in participants with early Alzheimer's Disease.

The primary purpose of this two-part study was to evaluate the safety and tolerability of SAGE-718 and its effects on cognitive, neuropsychiatric, and motor symptoms in participants with Parkinson's disease mild cognitive impairment (PD-MCI).

The aim of this study is to compare the effects of single and dual-task training on processing speed, cognitive functions, walking speed, dual-task performance and balance functions in individuals with mild cognitive impairment.

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.
