Active clinical trials for "Cognitive Dysfunction"

The purpose of this study is to assess the effect of a single oral dose of TAK-071 on the attenuation of cognitive deficit induced by scopolamine as measured by Groton Maze Learning Test (GMLT) (total number of errors).

Although saliva is not generally regarded as one of the most interesting biological fluids, the fact that it can be sampled using simple, noninvasive methods makes it an interesting alternative to cerebrospinal fluid (CSF) or blood for diagnostic purposes. The use of salivary diagnostics is moreover increasing these past 10 years, as shown with the abundant literature as well as various clinical trials. Saliva collection which is now well standardized has the major advantage of being simple and non-invasive. An original study had already discussed possible changes in the salivary composition in Alzheimer's disease (AD). The feasibility and the potential interest of measuring saliva concentration of the amyloid peptides was reported in an article published recently. The prospect of using saliva for early diagnosis and monitoring of AD is thus of major interest and the objective of the current trial.

The primary objective is to evaluate the efficacy and safety of phosphatidylserine (PS) on cognitive abilities in MCI

The purpose of this Phase 1/Phase 2 study is to evaluate how the body handles the drug and the drug's effect on the body of participants with mild cognitive impairment (MCI) due to Alzheimer's Disease (AD) or mild AD and who test positive for amyloid plaque.

Population aging in Portugal has led to problematic social issues (American Psychiatric Association, 2013; Spector, Woods & Orrell, 2008; Wimo & Prince, 2010). At the same time, there is a noticeable increase in the prevalence of Neurocognitive Disorders (NCDs), commonly referred to in clinical practice as mild cognitive impairment and dementia (Apóstolo, Cardoso, Silva & Costa, 2014; Apóstolo & Cardoso, 2014). NCDs can be classified based on the degree of cognitive decline, ranging from mild to major, and based on etiology, which includes Alzheimer's disease, Vascular dementia, Lewy body dementia, Frontotemporal dementia, and others (American Psychiatric Association, 2013). In the European context, Portugal is among the minority of countries that do not have an official strategy for the care of people with mild cognitive impairment and dementia. Therefore, it is imperative to define national health policies that address the identified needs (Knapp et al., 2006). Currently, non-pharmacological interventions, such as Individual Cognitive Stimulation (ICS), are gaining relevance as treatment responses to the aforementioned syndromes, due to the increasing clinical, social, and economic impact of mild cognitive impairment and dementia (Aguirre, Hoare, Spector, Woods, & Orrell, 2014; Apóstolo et al., 2014). ICS can be considered the implementation of a set of meaningful activities, carried out over several sessions, usually in a social context, with the aim of stimulating various domains, including attention, thinking, language, memory, and calculation (Aguirre et al., 2012; Apóstolo et al., 2014; Yates, Orrell, Spector & Orgeta, 2015). Current evidence supports the effectiveness of this intervention, indicating that ICS programs are associated with health benefits, particularly in cognition, mood, well-being, functional activity, quality of life, and communication skills (Apóstolo et al., 2014; Yates et al., 2014). Providing care to people with mild cognitive impairment and dementia poses a challenge for the healthcare system, necessitating the implementation of specific interventions to increase self-care potential, autonomy, adaptation, and coping with deficits, as well as empowering the family and/or support network (Alzheimer Europe, 2013; Orrell et al., 2012; Woods, Aguirre, Spector & Orrell, 2012; Yates et al., 2015). Due to the global pandemic context of SARS-CoV-2, social care institutions for the elderly underwent changes in their dynamics. One of the measures implemented during the emergency plan was the closure of adult day care centers. The elderly who previously attended these social care facilities are now staying in their own homes or with family/informal caregivers, thus being deprived of the social and cognitive stimuli they were accustomed to. The mobilization of this population to their homes has led to increased social isolation and loneliness, which are underestimated public health risks. These factors affect a significant proportion of the elderly population and can lead to cognitive decline, feelings of loneliness, sadness, and abandonment, which were previously alleviated by the social care centers (National Academies of Sciences, Engineering, and Medicine, 2020). Given the described situation, the Making a Difference 3 program - an ICS program - represents an excellent implementation option, as it can be developed in various contexts, including the home environment, using cost-effective resources, addressing many of the needs of both individuals with cognitive impairment and their informal family caregivers. In summary, in Portugal, there is no established practice of implementing structured ICS interventions with individual sessions for use in the home environment. Thus, there is a need for the MD3 program to be disseminated to promote best practices. In response to the needs arising from the current pandemic context, the team of this project aims to produce national evidence on the effect of ICS in individuals with mild cognitive impairment and dementia, in the home environment of the elderly person, managed by informal caregivers and supervised by healthcare professionals.

The study aims to understand the mechanisms and training effects of evidence-based body-mind training on improving cognitive performance and preventing cognitive decline.

To investigate the effect of ultrasound-guided thoracic paravertebral nerve block combined with intraoperative infusion of s-ketamine on postoperative acute pain and cognitive function in patients with thoracoscopic surgery

The goal of this Phase 2 MCI study is to determine whether 1.0 mg/kg XPro1595 is superior to placebo at improving measures of cognition, functioning and brain quality in individuals with MCI and biomarkers associated with neuroinflammation (APOE4) and to evaluate safety, tolerability, and efficacy of XPro1595.

In the last 25 years, there has been a lot of attention directed on reducing perioperative morbidity and mortality by improving intraoperative monitoring and hemodynamic optimisation of patients. Advanced monitoring devices and new parameters have shifted the focus of anaesthesia management from macro- to micro circulation with the emphasis on the determinants of oxygen delivery and tissue oxygenation. There is increasing evidence that long-term outcome is improved by goal-directed optimisation of hemodynamic parameters (optimisation of stroke volume and cardiac output by fluids and inotropic and vasoactive drugs). Besides, new monitoring possibilities (depth of anaesthesia and cerebral and tissue oxygenation monitors) and adherence to protocols have proved beneficial in reducing morbidity cognitive dysfunction. However, questions are raised what the optimal goals (healthy population derived normal values, preoperative values, maximal values, restrictive fluid management) should be. Secondly, all new methods were used separately and there is a lack of studies to show the effect of combined (multimodal) monitoring on occurrence of cognitive dysfunction. All gathered data indicate that the combined use of new methods with adherence to an appropriate protocol might radically improve the perioperative management and outcome of high-risk surgical patients. The present study tests the hypothesis that intraoperative multimodal monitoring with hemodynamic optimisation, BIS-guided anaesthesia and maintenance of optimal cerebral oxygen saturation will reduce cognitive dysfunction.

The study will provide insight into how lifestyle-related interventions, specifically nutrition and exercise can impact the health of older women. The study uses a unique combination of interventions and encapsulates overall health outcomes by measuring both mobility and cognitive function. The study examines the effects of a combined omega-3 polyunsaturated fatty acid (PUFA) and multi-nutrient supplement on measures of mobility and cognition in women aged 60 years and above. Volunteers for the study will be randomly assigned to one of four groups which are as follows: Omega-3 PUFA multi-nutrient supplement and aerobic exercise Omega-3 PUFA multi-nutrient supplement and no exercise Placebo supplement and aerobic exercise Placebo supplement and no exercise Volunteers undertake the dietary supplementation for a period of 24 weeks. The active dietary supplement contains a daily dosage of 1 g docosahexaenoic acid, 160 mg eicosapentaenoic acid, 240 mg Ginkgo biloba, 60 mg phosphatidylserine, 20 mg d-α tocopherol, 1 mg folic acid, and 20 µg vitamin B12. The placebo supplement contains an iso-calorific oil blend that is typical of the current UK diet. The aerobic exercise consists of two classes per week the final 12 weeks of the study on stationary spinning exercise bikes. Volunteers attend testing at the beginning and after 24 weeks. Verbal memory, spatial working memory, executive function and processing speed are assessed via a battery of cognitive tests. Mobility testing comprises three walking tests, some under single and dual task paradigms, as well as the five times sit to stand test, a measure of dynamic balance and functional mobility. Volunteers also provide two blood samples, one for fatty acids analysis and the other serum homocysteine levels. Participants also complete health-related quality of life questionnaire, the short form 36 (SF36) questionnaire, food diary and food frequency questionnaire.
