Filter by:The aim of the current study is to investigate whether acute and 12-weeks daily intake of Nordic berries can improve cognitive abilities of adults without cognitive disease, and whether the effect can be linked to changes in metabolic parameters.
Randomized, double-blind, parallel groups, placebo-controlled, baseline/run-in period of 21 days followed by trial period of 21 days, digital phenotyping (sleep, cognitive/psychological parameters and HRV). The aim of this study is to determine the feasibility of investigating the effects of Redormin® 500 on day-time cognition and to assess psychological parameters (subjective cognitive performance, tiredness, mood, stress level, quality of life, motivation), in people with occasional sleep problems. Sleep tracking data will be collected using consumer devices of the Charge series by Fitbit.
The purpose of the research study is to investigate whether the extent and severity of lesions in the brain as measured by special MRI techniques can distinguish between Multiple Sclerosis (MS) patients with or without memory impairment and also between MS patients and age matched healthy controls.
This study investigated the efficacy of the Silvia program, a mobile-based multidomain intervention, to improve cognitive function and health-related outcomes of older adults with a high risk of dementia. We compare its effects to a conventional paper-based multidomain program on various health indicators related to risk factors of dementia.
COMBI is a multi-center, randomized controlled trial among 70 older adults at risk of cognitive decline. The main goal is to investigate the effect of a 6-week colon-delivered multivitamin supplementation on the gut-brain axis in older adults, by assessing changes in brain function as well as intestinal changes compared to placebo.
The present study will investigate the correlation between objective and subjective cognition in multiple sclerosis. The study will also investigate the impact of covariates such as fatigue and depression, the relationship with the Expanded Disability Status Scale (EDSS) and brain volumetrics as measured on magnetic resonance imaging (MRI). Additionally, the study will provide insights into patients' experiences with cognition, and the usability of the used objective cognitive assessments.
Different cognitive rehabilitation intervention methods have been developed for the treatment of cognitive dysfunctions seen in mild cognitive impairment (MCI). The aim of this study was to examine the effectiveness of cognitive rehabilitation intervention applied with the telerehabilitation method in elderly patients with amnestic-MCI. Participants included in the study according to inclusion and exclusion criteria were randomly assigned to the telerehabilitation and face-to-face groups. A 12-week cognitive rehabilitation intervention was applied to both groups. Pre- and post-intervention cognitive skills of the participants were evaluated using the Loewenstein Occupational Therapy Cognitive Assessment-Geriatric (LOTCA-G).
Clinical and epidemiological studies suggest links between cognitive impairments and Type 2 diabetes (T2DM). The underlying mechanisms and causality in diabetes-related cognitive impairment are largely unknown. The aim of this study is to investigate cognitive impairment and the role of BDNF in prediabetes and diabetes patients.
In this study, we investigated the effect of the capacity to cope with oxidative stress (oxidative stress response during and after clamping) in individuals with cerebral oximetry level between 40- 60 % and above 60 % and their effect on cognitive functions. Methods: In this retrospective study, patients who were scheduled for carotid endarterectomy, examined the MOCA tests before and after the operation and collected blood samples intraoperatively were included between January 2020-2021. The time periods specified below, blood samples were taken and serums were frozen at -80 celcius all this patients. Montreal cognitive function assessment test was applied before the operation, 24 hours and 7 days after the operation. Ten mililiters venous blood samples were collected to examine the status of basal neuron specific enolase, S100B, oxydative stress parameters (HAF-1 and DAF-1) at time intervals. Time intervals as follow: T1: Peripheral baseline measurements (blood will be taken from arterial blood sampling) + Cerebral Oxymeter levels + Montreal cognitive performance test + Modified Rankin Scale (mRS) T2: 1 minute before clamping (from peripheral and jugular vena blood sampling) + Cerebral Oxymeter levels T3: Before opening clamp(from peripheral and jugular vena blood sampling) + Cerebral Oxymeter levels T4: 24 hours after the procedure. (peripheral blood sampling) + Montreal cognitive performance test T5: 7 days after the operation. (peripheral blood sampling) + Montreal cognitive performance test + CO levels+ Modified Rankin Scale (mRS) Results: We found significantly positive corelation between cerebral oxymeter levels, oxydative stress parameters and cognitive performance tests in this six patient.
This study is testing cognitive function before and after the surgery, with patient's informed consent. Patients of interest are 65 year or older, undergoing surgery in general or regional anesthesia. Investigators are using 3 tests. These are: MMSE (Mini Mental State Exam), TEGEST test (test of gestures) and Clock drawing test. Tests after surgery are performed 2 days until discharge. The testing is anonymous, patient is assigned a number. Main aim of this study is to find a suitable quick test of cognitive function for clinical practice before surgery in general or regional anesthesia.
