Filter by:Introduction and Purpose: In recent years, non-pharmacological treatment methods for dementia patients have been gradually explored. Among these, Transcranial Magnetic Stimulation (TMS) has been proposed as a non-invasive treatment option. However, the optimal frequency and stimulation site for repetitive transcranial magnetic stimulation have not been definitively determined. Methods: This study is a randomized controlled trial. We randomly assigned 30 patients with mild cognitive impairment or dementia to the high-frequency transcranial magnetic stimulation group (40 Hz rTMS) or the moderately high-frequency transcranial magnetic stimulation group (10 Hz rTMS). Stimulation was applied to the bilateral dorsolateral prefrontal cortex (DLPFC). Each patient received a course of treatment for 10 consecutive working days. The high-frequency group received pulses at 40 Hz with an intensity of 40% of the maximum intensity for 2 seconds followed by a 58-second rest period, per set. The moderately high-frequency group received pulses at 10 Hz with an intensity of 90% of the maximum intensity for 4 seconds followed by a 56-second rest period, per set. Each day, patients received 30 sets of stimulation (15 times on the left side and 15 times on the right side), totaling 2400 pulses. Cognitive assessments were conducted on patients before and after the treatment course. Quantitative analysis will be performed using the Statistical Package for the Social Sciences statistical software. The Kolmogorov-Smirnov test will be used to check if the data follows a normal distribution. The chi-squared test will compare differences in baseline categorical variables between the groups, while independent t-tests or the Mann-Whitney U Test will compare baseline differences in continuous variables to assess the effectiveness of random assignment. Analysis of variance (ANOVA) and post-hoc comparisons will be used to compare intergroup and intragroup differences. The significance level is set at α = 0.05.
This pilot feasibility study will be a randomized control trial of usual care following Intensive Care Unit (ICU) discharge compared to the Anticipating Decline and Providing Therapy (ADAPT) screening and support intervention. The trial aims to enroll 120 older adults (age 60 or older).
This is a randomized, double-blind, sham-controlled, adaptive-design pivotal study of sensory stimulation in subjects with mild to moderate Alzheimer's disease. Approximately 530 subjects will be randomized to 12 months of daily treatment with either Active or Sham Sensory Stimulation Systems. Efficacy will be measured using the Alzheimer's Disease Cooperative Study- Activities of Daily Living (ADCS-ADL) assessment and a combined statistical test (CST) of the ADCS-ADL and the Mini-Mental State Exam (MMSE).
The goal of this study is to learn about the effects of scopolamine (an anticholinergic drug) on areas of the brain involved in memory, and changes it may have on brain activity. The investigators will do this by testing epileptic patients who are already undergoing intracranial surgery for seizure monitoring, and measuring the activity from the brain areas being assessed. The main questions it aims to answer are 1) whether scopolamine changes memory activity solely at encoding (the time when the person perceives and determines to remember an item or event) as has previously been found, or if it also can selectively impact retrieval (when the item or event which has been processed is recalled or remembered), and 2) what the nature of the brain activity changes is. Participants will complete two treatment arms. One of these will be with the drug, and the other will be with a saline solution, so that the participants are unaware which session the actual drug has been received. Patients will complete a verbal and/or spatial task each of the two days. An anesthesiologist will administer either the drug or the saline at a critical point which addresses both of the research questions. Researchers will compare the brain activity between the two treatment arms to determine what brain activity changes, and at what time point during memory formation.
The purpose of this study is to investigate neurocognitive mechanisms underlying response to intervention aimed at enhancing, and remediating weaknesses in, numerical skills in children, including those with mathematical learning disabilities (MLD).
The purpose of this study is to test the feasibility of a telehealth Dyadic Life Review (DLR), adapted from individual Life Review Therapy, with caregivers of older adults with advanced cancer, including those with Mild Cognitive Impairment (MCI). The study will enroll 20 dyads of caregivers and older patients with advanced cancer and 20 dyads of caregivers and patients with advanced cancer and Mild Cognitive Impairment (MCI).
Develop a game-based upper-extremity motor and cognitive rehabilitation system using custom and adaptable virtual reality simulations on a wearable device enhanced with biosensors. Participants are stage II and stage III breast cancer survivors with lasting cognitive impairments following their first round of chemotherapy. They will be randomized 1:1 into an experimental group and a sham control group. Each group will train in the home for 8 weeks, during which they will perform up to 4 rehabilitation sessions/week (based on tolerance). Each session will start with vitals being measured and logged. Each group will have three clinical evaluations: 1) at baseline; 2) at 8 weeks post-baseline; and 3) at 16 weeks from baseline for follow up. Experimental group sessions will consist of increasingly more difficult cognitive training tasks in the form of simulated tasks. Biosensors will be sampled while participants interact with these games while wearing the computer system. Sham control group will have the same number, suration and frequency of sessions, however they will play web games while wearing some the same biosensors. Caregivers of all subjects will receive a laptop to be used in filling subjective evaluation forms and sending messages to research team. Training will be in the home, so caregivers will need to support the trials by ensuring compliance with the protocol. All subjects will undergo standardized clinical evaluations at baseline, at 8 weeks and at 16 weeks from baseline. The subjects in the experimental group will have computerized measures taken during each session, and will fill subjective evaluation forms every 4 weeks of active training.
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.
Nonamnestic mild cognitive impairment (naMCI) is a prodromal state characterized by deficits in executive functioning, a collection of higher-order abilities involved in organization, planning, inhibition, and complex reasoning. Research shows that individuals with naMCI have an increased risk of developing non-Alzheimer's dementia such as frontotemporal dementia and dementia with Lewy bodies, which pose substantial personal and societal costs. Accordingly, interventions that can successfully slow down or reverse the course of naMCI are needed. Goal Management Training (GMT) is a cognitive rehabilitation platform that has been studied extensively, applied clinically, and manualized into kits for clinicians (Levine et al., 2000; Levine et al., 2007; Levine et al., 2011; Stamenova & Levine, 2019). The purpose of GMT is to train individuals to periodically "STOP" what they are doing, attend to task goals, evaluate their performance, and monitor or check outcomes as they proceed. Recently, an online version of GMT has been developed and validated in order to circumvent barriers to attending in-person sessions. The purpose of the current study is to determine if the online version of GMT is effective at improving self-reported executive dysfunction in individuals diagnosed with naMCI against a control group that is receiving treatment-as-usual from their care provider. It is hypothesized that, compared to the control group, individuals receiving GMT will report a decrease in executive function deficits.
PREVENTABLE is a multi-center, randomized, parallel group, placebo-controlled superiority study. Participants will be randomized 1:1 to atorvastatin 40 mg or placebo. This large study conducted in community-dwelling older adults without cardiovascular disease (CVD) or dementia will demonstrate the benefit of statins for reducing the primary composite of death, dementia, and persistent disability and secondary composites including mild cognitive impairment (MCI) and cardiovascular events.
