Active clinical trials for "Cognitive Dysfunction"

The purpose of this study is to see how early cognitive training (participation/involvement in activities to stimulate the brain) in the Intensive Care Unit (ICU) affects the number of patients who experience delirium (confusion) and cognitive impairment (problems with thinking). Reports have shown that 30% to 80% of all ICU patients will have some type of cognitive impairment: remembering, paying attention, solving problems, organizing, and working on complex tasks for some time after they leave the hospital. Occupational therapy will do an assessment after an order is received from the doctor. The patient will be randomly placed into one of two groups. If the patient is in group A then they will continue with occupational therapy as normal. If the patient is assigned to group B then they and the family will have access to an activity cart found there in the ICU unit, directed by the nurses. The family will work with the patient on a daily basis to complete activities that are appropriate for the patient based on the occupational therapist's assessment. All patients in the study will receive medical care as usual. Information about the patient's recovery in the hospital will be collected. In addition, patients and/or their family member will complete surveys at 6 months and 1 year after enrollment to see how they have recovered and if there are continuing issues. The two groups of patients, those who received the early cognitive training and those who did not, will be compared statistically to see if there are any differences in how well they recovered. Since this intervention involving family members working with the patient has not previously been evaluated, the study will also examine the feasibility of conducting these activities in the ICU setting.

The purpose of the study is to see if a commercially available hearing assistance device called the PockeTalker has an effect on performance on cognitive (memory and thinking) tests among skilled nursing facility residents. Investigators are asking residents to perform cognitive tests with and without hearing assistance equipment known as PockeTalkers. This study will be conducted at one urban Skilled Nursing Facility (SNF) with the goal of understanding the extent to which hearing impairment impacts commonly used cognitive impairment measures for clinical assessment. Cognitive performance will be measured, cerumen occlusion, and perceived hearing.

This pilot study will look at whether it is possible to give better physical therapy to people with cognitive limitations who have had a hip fracture.

For this study, 213 individuals with Mild Cognitive Impairment were recruited. The study period ran from June 2018 to October 2021. The procedure involved a combined screening and baseline examination, including oral, medical, cognitive, and quality-of-life examinations. Re-examinations followed this at 6, 12, and 24 months. The examinations were performed at a university research clinic, and all participants received their usual medical and dental care during the study. At baseline, each participant received a powered toothbrush. Participants were carefully instructed on how to operate the powered toothbrush and were asked to brush for at least two minutes in the morning and evening. No restrictions were given against the use of other oral care products. Compliance with the powered toothbrush was followed by a participant survey conducted at each examination.. Facilitating and improving life by introducing a powered toothbrush as part of oral hygiene may benefit individuals with MCI. This study aimed to investigate whether the use of a powered toothbrush could maintain or improve oral health by reducing dental plaque (PI), bleeding on probing (BOP), and periodontal pocket depth (PPD)≥4mm in a group of individuals with MCI for an observation period of 24 months. Furthermore, to study how oral health changes affect QoL aspects.

The study has a mixed-methods design i.e. integration of qualitative and quantitative data within a single investigation. Participants included will be patients ≥60 years that are undergoing major elective joint replacement surgery (n=40) and their relative. Patient's experience of his/her cognition will be capture by interviews on postoperative day 13-16 during the follow-up visit and after 1 year. A relative will also be interviewed once on postoperative day 13-16. Cognitive function will be measured preoperatively and on postoperative day 13-16 using the International Study Group of Postoperative Cognitive Dysfunction (ISPOCD) test battery. Symptoms / discomfort will be measured pre- and postoperatively (on postoperative day 1 and 2 and at the follow up visit day 13-16) by the Swedish version of Quality of Recovery (SwQoR) and by a visual analogue scale assessing pain intensity. Biomarkers will also be collected at the same time points. The findings from the interviews will be sorted out depending on group stratification (no delayed neurocognitive recovery and delayed neurocognitive recovery). The qualitative and quantitative findings will be compared to seek for similarities and differences.

Whereas the advantageous effects of exercise-training on memory is increasingly recognized, the practicality and clinical usefulness of such interventions in community-dwelling older African Americans (AA)s Mild Cognitively Impaired (MCI) subjects, and the mechanism by which an effect occurs need elucidation. Because aerobic-exercise can improve emerging cardiovascular (CVD)-related risk factors for cognitive decline such as lipids, inflammatory cytokines and glucose homeostasis; the Investigators will examine training effects on these and related biomarkers. The imperative for this study is further underscored by the fact that, AAs: i) have high rates of dementia, and ii) have paucity of cross-sectional, and lack prospective data on the effects of exercise on cognition. To overcome barriers to recruitment and retention, enhance compliance with a long exercise program (3-times/week), and maximize the use of available resources, the Investigators will use a community-based approach. Therefore, the primary objectives of this study build on the Investigators' experience, and will compare the effects of aerobic-exercise to stretch-exercise (control) in community-dwelling AA MCI subjects. Following the initial 6 months active intervention, the aerobic-exercise group will follow a prescribed but free living 40 minutes, 3 time/week exercise regimen while the control group returns to usual care plus stretch-exercise for additional 12 months. This study will facilitate the estimation of sample size for a larger confirmatory study in AAs. A newly acquired direct oversight of the DC Ward-6 Senior Wellness Center and its infrastructures by the Howard University Division of Geriatrics will provide additional resources and access to the community. In addition to the Investigator's feasibility aims, the Investigators will determine performance on cognitive tasks using the Alzheimer's Disease Assessment Scale-Cognitive Sub-scale (ADAS-Cog) and Clinical Dementia Rating Scale (CDR) sum of boxes supplemented by tests of executive function (EF) and Functional Activity Questionnaire (FA) and together as ADAS-Cog-Plus; changes in brain volume regions of interest (ROI) with Magnetic Resonance Imaging (MRI), selected CVD and AD-related bio-markers.

The purpose of this study is to determine whether baroreceptor sensitivity (the ability of your body to change your heart rate and/or blood pressure in response to a situation) has any effect on how likely you are to suffer certain events after heart or lung surgery. The postoperative events that the investigators will be studying are pain after surgery, atrial fibrillation (an irregular heart rhythm), and cognitive dysfunction (a decline in mental abilities).

The Imaging Dementia-Evidence for Amyloid Scanning (IDEAS) Study will establish an open-label, longitudinal cohort study to assess the impact of amyloid PET on patient outcomes. The study will be performed in accordance with the Center for Medicare & Medicaid Services (CMS) policy of Coverage with Evidence Development (CED) in Medicare beneficiaries who meet the Appropriate Use Criteria (AUC) for amyloid PET (Johnson et al. 2013). Our hypothesis is that amyloid PET will decrease uncertainty and increase confidence in the underlying cause of cognitive impairment, that this will translate into earlier counseling and interventions in these domains, and that these interventions will lead to improved outcomes.

Cognitive dysfunction is a highly persistent, pervasive and progressive abnormality in young adults (i.e., 18-65 years) with MDD. It has also been shown that among adults with MDD who are gainfully employed, measures of cognition are a greater determinant of overall workplace performance than is total depression symptom severity. Several lines of evidence indicate that cognitive deficits that persist between episodes of depression are critical determinants of functional recovery in the workplace. The functional implications associated with cognitive impairment provide the impetus for systematic evaluation, measurement and assessment of the domains of cognition expected to be impaired in this patient population. To date, no measurement tool has been sufficiently validated and/or determined to be sensitive to the cognitive deficits in younger adults with MDD. Major limitations of available comprehensive psychometric tools include relative lack of availability, cost, lack of access to most healthcare providers, and above all else, the lengthy time to administer. Moreover, the need for a psychometrist to interpret the results adds to the complexity and the costliness of such an endeavor. It is imperative that any tool recommended for clinical utility be aligned with the busy nature of a high-volume clinical practice. The ideal gold standard tool for assessing the presence of cognitive dysfunction in MDD in the clinical environment should include, but not be limited to, features such as good conceptual coverage of cognitive domains affected in MDD, good sensitivity and reliability, and it should be relatively uninfluenced by culture effects and practice effects. The tool would also need to be brief, easy to administer and interpret, and complement busy clinical practice. This study is designed to validate a brief user-friendly tool capable of detecting deficit in cognitive performance among adults with MDD. Data will be gathered with the aim to determine whether the proposed tool identifies cognitive deficits in adults with MDD and differentiates the clinical MDD population from healthy controls. It is anticipated that the THINC-it tool will be free of charge and downloadable from the THINC-it website for use in the primary care and specialty setting. The THINC-it tool will be accessible via computers/tablets, will take 20 minutes to self-administer in a clinical setting, and the performance results will be immediately available.

The purpose of this study is to examine relationships among lifestyle behaviors (i.e., physical activity, sleep), cognitive function (i.e., memory, processing speed, and executive function), and quality of life in breast cancer patients and survivors across time. The investigators will compare the strength of these relationships across age cohorts and time since treatment and diagnosis. Participants will complete a battery of questionnaires and a set of cognitive tests on an iPad app specifically tailored for this study. A subset of participants will also wear an accelerometer for seven days. Data will be collected at baseline and 6-month follow-up. This research is critical to identifying potentially important approaches to improving health outcomes and quality of life in breast cancer patients and survivors. Previous research provides evidence of the influence of lifestyle behaviors on cognition and quality of life in healthy aging populations. However, despite data indicating cancer's negative impact on lifestyle behaviors, cognition, and quality of life, very few studies have investigated interactions among these factors in cancer patients and survivors.
