Filter by:Emerging literature suggests that vascular factors might be involved in the pathogenesis of Alzheimer's disease (AD). Other recent studies demonstrate the positive effects of physical activity on cognitive and behavioral disturbances of patients with AD. Therefore, it has been postulated that exercise enchantment in cerebral circulation is the physiological mechanism that link physical exercise and reduction of AD symptoms. Consequently, a program of physical activity could be considered one approach to counteract dementia by improving cerebrovascular health. However at this moment, it is not clear if the progressive brain vascular dysfunction and hypoperfusion, associated with the β-amyloid deposition, might be reversed or stabilized by an exercise intervention. The aim of this study is to assess, in patients with AD, the influence of physical exercise, compared to cognitive stimulation, on: - Cognitive function; - Independence in daily living and behavioral symptoms; - Vascular function Finally, to investigate the physiological processes on the basis of the motor parameters' changes, the performances of the patients will be compared with the performances of healthy young and old subjects. MAIN OBJECTIVE: Investigate, in patients with Mild Cognitive Impairment (MCI) and AD, the effects of a physical activity program, or cognitive stimulation on global cognitive function. SECONDARY OBJECTIVES: Investigate the effects of the two treatments on: - cognitive and motor performances, - independence in activities of daily living, - behavioral symptoms, - peripheral vascular function.
Follow-up after treatment with Extracorporeal Membrane Oxygenation (ECMO) at the ECMO Center Karolinska. Patients: adult survivors treated with ECMO for severe refractory respiratory failure at least 5 years earlier. Investigations: brain and pulmonary radiographic morphology, cognitive testing, pulmonary function testing, exercise tolerance, quality of life and mood disorder screening.
This is a pilot randomized control trial with single blinding of the assessor that will be conducted in two nursing homes residence to evaluate the applicability of a physical exercise program performed in an aquatic environment compared with the same realization but land-based to reduce falls in the institutionalized old people. The secondary objectives are to study the applicability of the intervention in improving balance, function, gait mobility, muscle strength of the lower limbs and the perception of the intervention.
This study will use systems biology techniques, especially RNA-seq, to understand cognitive impairment after sepsis requiring an intensive care unit (ICU) admission.
This study evaluates an agenda-setting checklist for patients with cognitive impairment and their family companions that is completed in the waiting room in advance of a primary care visit. The study team will conduct a two-group randomized trial to examine feasibility of the protocol and to compare medical communication (from visit audiotapes) during visits of patient-companion dyads who complete the checklist (n=50) with patient-companion dyads who receive usual care (n=50)
The objectives of this study are to determine whether identifying patients with baseline cognitive deficits or frailty predict postoperative delirium.
By doing this study, researchers hope to learn if older adults with and without cognitive impairment can adhere to a Mediterranean diet.
Is HMGB1 (High Mobility Group Box 1) elevated in sepsis patients for weeks after recovery from severe sepsis/septic shock, similar to what has been observed in mice? Do patients recovering from severe sepsis/septic shock suffer from cognitive impairment and is such impairment associated with prolonged HMGB1 levels in plasma? Is there a difference from patients recovering from critical illness without prior sepsis?
The proposed study is designed to evaluate the performance of the ALTOIDA™ System as a tool to assist physicians in diagnosing Alzheimer's Disease (AD) in real-world clinical settings. The design of this study is guided by two overriding factors: 1) to optimize the performance of the ALTOIDA™ Neuro Motor Index (NMI) prognosis classifiers, the subjects making up the training sets must be well characterized as to their clinical diagnosis, and 2) all ALTOIDA™ tests must be performed and reproduced in real-world clinical settings. Although there is already a large body of peer-reviewed scientific literature demonstrating that certain digital biomarker patterns are associated with certain neurologic conditions, the utilization of such tools for the evaluation of neurologic disorders is still considered an emerging science and therefore in the investigational stage. Although this protocol will report on brain patterns of certain neurologic conditions such as cognitive impairment and Alzheimer's disease, based on patterns published in peer-reviewed journals, such findings are not considered stand alone or diagnostic per se and should always be considered by the primary physician in conjunction with the patient's clinical condition. These data should only be used as additional information to add to the primary physician's diagnostic impression.
Primary study: This study is a single-site, double-blind, randomized, controlled clinical trial to compare an evidence-based structured program of 30-35 hours of on-line cognitive and social cognitive training exercises performed over 16 weeks (~2 hours per week), delivered with an innovative digital app which provides users with a motivation coach to set personalized goals and with secure social networking for peer support, "PRIME" ; vs. 2) A control condition of computer games, encouraged at ~2 hours per week over 16 weeks, delivered with "PRIME". Unblinded Cognitive Training Sub-Study: Participants who were randomized to the computer games arm of the trial may be offered access to the active cognitive training at the end of their 6 month follow up appointments, if they still meet inclusion criteria. PRIME Super Users Sub-Study: Participants who have provided all follow up data to the initial study, including those who are currently enrolled in the Unblinded Cognitive Training sub-study, may be offered continued participation in the PRIME community as super-users.
