Filter by:Nowadays, on geriatric centres, cognitive decline used to be prevented by pen and paper exercises (Calero García & Navarro Gonzalez, 2006). However, as Lampit et al. (2014) suggest, studies based on the efficacy and effectiveness of new cognitive-based interventions in order to improve these cognitive processes are fundamental (Lampit et al., 2014). Cognitive-based interventions are interventions that directly or indirectly try to improve cognitive processes (Chiu et al., 2017). Between the different kinds of cognitive-based interventions, cognitive training permits stablish randomized controlled trials. Cognitive training consists of repeating during a concrete time a standardized set of tasks in order to maintain or improve one or some cognitive processes. Meta-analysis studies have shown that computerized cognitive training can improve in a moderate size some cognitive processes in elderly people with mild cognitive impairment or dementia (Hill et al., 2017) and without those diagnoses (Lampit, Hallock, & Valenzuela, 2014; Chiu et al., 2017). Although it seems that computerized training is effective, safe and secure, it is important to note the social component of the definition of health (OMS, 1948). Chang, Wray & Lin (2014) found that social relationships predict the use of leisure activities and this predict a better physical health and wellbeing psychological. In fact, a comparative study found that those elderly people that have played board games have a 15% lower risk of having dementia diagnose and problems related with memory (Dartigues et al., 2013). To sum up, the aim of this research project is to test the effectiveness of a cognitive training based on modern board and card games in elderly people with a diagnose of mild-cognitive impairment in comparison to do cognitive paper and pencil tasks or in a wait-list comparison group.
In developed countries, the acceleration of the general population ageing has been widely described for decades, involving changes in public health policies. Among the health issues arising from this demographic change, the maintenance of cognitive function will be a major challenge in the next years, both in societal and economic terms. In this regard, some pharmacological and behavioural (e.g. physical activity, social involvement, intellectually demanding activities) preventive approaches have been evaluated to improve cognitive function with ageing. Among them, dietary interventions showed a potential interest to prevent cognitive decline during ageing. In this sense, there is a growing interest to find ecological solutions and to meet major societal challenge the use of microalgae as molecule of interest sources is a recent promising approach. Marine environments harbour a huge biological diversity of microalgae that represents a large source of almost untapped bioactive compounds. This biodiversity comprises 200,000 to 2 million species with about 35,000 which are described and 15,000 maintained in culture collections. Microalgae are able to produce bioactive molecules, such as pigments, fatty acids, peptides and sterols. Some of these compounds are unique and specifically found in the marine environment and they could be increasingly used as natural bioactive products for targeted applications. Fucoxanthin is one of the major carotenoid found in microalgae well known for its neuroprotective effect but to our knowledge no human studies were realized. Thus the objective is to evaluate, in healthy older adults, the effect of a 24-week period of daily supplementation of high and low BrainPhyt, doses on cognitive function parameters (Spatial Working Memory scores, Attention and vigilance, episodic memory, executive function), stress, mood, sleep quality and biomarkers.
The primary objective of the study is to evaluate whether a set of algorithms analysing acoustic and linguistic patterns of speech can detect amyloid-specific cognitive impairment in early stage Alzheimer's disease, as measured by the AUC of the receiver operating characteristic (ROC) curve of the binary classifier distinguishing between amyloid positive (Arms 1 and 3) and amyloid negative (Arms 2 and 4) Arms. Secondary objectives include (1) evaluating whether similar algorithms can detect amyloid-specific cognitive impairment in the cognitively normal (CN) and MCI Arms respectively, as measured on binary classifier performance; (2) whether they can detect MCI, as measured on binary classifier performance (AUC, sensitivity, specificity, Cohen's kappa), and the agreement between the PACC5 composite and the corresponding regression model predicting it in all Arms pooled (Wilcoxon signed-rank test, CIA); (3) evaluating variables that can impact performance of such algorithms of covariates from the speaker (age, gender, education level) and environment (measures of acoustic quality).
The purpose of this study is to see whether programs that include both a patient and their spouse or a patient and family caregiver (known as a dyad) are helpful for families in which one member of the dyad has cancer and mild memory difficulties and/or concerns. Participant and their spouse or participant and their family caregiver will have six, 60-minute video-conference sessions which will be scheduled at their convenience. The investigator will loan participants a tablet computer (iPad) to use for videoconferencing and train the participant in its use. Participant and their spouse or participant and their family caregiver will complete three assessments - one before starting the sessions, one after the sixth session, and one after 1 month. Each assessment will include surveys, which the participant will complete separately from their spouse or family caregiver. For most people, it will take upwards of 2 - 4 months to complete this study.
Harmful alcohol use is a global risk factor for disease, injuries and death. Research on treatment of Alcohol use disorders (AUDs) indicates that different treatment modalities are equally effective, but also that a large group of patients do not change their drinking pattern despite being in treatment. It is assumed that it is not random who benefits from treatment. Thirty to forty percent of outcome variance in treatment is probably explained by patient factors, and we need more knowledge on how different patient factors moderate treatment effects. Further, clinicians also need more knowledge about selecting patients to different therapies. The present study will investigate how patient factors predict outcome in group treatment of AUDs, and what predicts positive treatment outcomes over time. The study is designed as a quasi-experimental, multi-centre, follow-up study. Patients will be included from Vestfold Hospital Trust, Borgestadklinikken, Blue Cross Clinic, Behandlingssenteret Eina, Blue Cross Clinic and A-senteret, Oslo, Church City Mission. The Project will provide more knowledge about patients seeking treatment for AUDs, and specifically how patient factors predict outcome in group treatment. These results will in turn lead to better selection of treatment modalities, and patients will receive a more effective treatment earlier on. Main aims: 1) How do patient factors predict outcome in group treatment of alcohol use disorders (AUDs)? 2) Do positive treatment outcomes last over time? Specifically, do the following factors: a) psychiatric comorbidity b) severity of alcohol use pre-treatment c) personality disorders and d) cognitive impairments predict 1) completion of group treatment and 2) positive outcome after 1 year. As an additional aim, we will investigate if the Montreal Cognitive Assessment test (MoCa) is feasible as a brief screening instrument for mild cognitive impairments for AUD patients.
Perioperative neurocognitive disorders (PND) have been studying by clinicians, particularly by anesthesiologists, pretty long, however the most inspiring advancements were achieved during the last few decades. The most recent classification of PND which includes cognitive decline diagnosed before operation (described as neurocognitive disorder); any form of acute event (postoperative delirium) and cognitive decline diagnosed up to 30 days after the procedure (delayed neurocognitive recovery) and up to 12 months (postoperative neurocognitive disorder) was proposed in 2017. However at will one can notice at least one uncertainty that pertinent to the definition of delirium, emergency delirium and not mentioned in the classification discussed agitation. The objective of the study is to determine if there is a difference between emergence agitation and emergence delirium.
Alzheimer's disease (AD) is one of the leading causes of disability in older adults. Because pharmacological approaches do not seem to prevent or slow the disease, clinicians need non-pharmacological interventions that might help people with AD remain independent for as long as possible. This study aims to evaluate the effects of a new behavioral treatment, the Structured External Memory Aid Treatment (SEMAT), for adults with mild cognitive impairment (MCI) designed to promote independent living skills by explicitly teaching the use of strategies and tools to compensate for cognitive weaknesses. Aim 1: Evaluate the efficacy of the SEMAT for improving functional performance in a pilot randomized trial. Aim 2: Evaluate demographic, clinical, and neuropsychological predictors of treatment adherence. Aim 3: Develop and refine the SEMAT manual and other materials for training future interventionists.
This study evaluates the efficacy of an early and intensive occupational therapy (OT) protocol in critical adult patients requiring mechanical ventilation. Evaluating the functional independence at hospital discharge.
When dementia is caused by AD, we refer to it as dementia of the Alzheimer's Type (DAT). The greatest risk factor for Alzheimer's Disease (AD) and DAT is advancing age, but DAT is not a normal part of aging. Studies have shown that changes in the brain happen before full symptoms of DAT develop. These changes include a buildup of two proteins within the brain, called amyloid and tau. The two goals of this study are (1) to determine whether patients with mild cognitive impairment or dementia-Alzheimer's type (DAT) are able to demonstrate decisional capacity to engage in PET amyloid and tau disclosure after receiving education; and (2) to assess how patients and care partners react to PET amyloid and tau biomarker disclosure.
The aim of this study is to investigate whether a high definition tDCS-accompanied intensive cognitive training of working memory leads to performance improvement in women with post-chemotherapy cognitive impairment after breast cancer treatment.
