Filter by:Recharge Rooms are immersive, biophilic private spaces designed to ameliorate trauma, anxiety, and stress. They feature multisensory input that is inspired by nature, as has previously been found to confer physiological benefits. These environments include silk imitation plants, projected scenes of soothing natural landscapes, low lighting that is tailored in color to match the landscapes that are being projected, high definition audio recordings of nature sounds paired with relaxing music, and infusion of essential oils and calming scents. The aim is to investigate the physiological and mental health outcomes that the short and long term exposure to these rooms have on healthcare workers. The data will be collected through online surveys. No identifiable information will be assessed or collected. The plan is to have 60 participants.
It was planned to compare the opioid consumption and cognitive functions in the postoperative period of patients who received TAPA block for postoperative analgesia and patients who did not prefer the block and who preferred intravenous patient-controlled analgesia (PCA) with opioids. Both the surgery applied and the drugs used in anesthesia can cause changes in cognitive functions by affecting the inflammatory process. It is thought that if the patients' pain can be relieved sufficiently in the postoperative period with TAPA block, the consumption of opioids used will be less and their cognitive functions will be less affected.
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 primary aim of this randomised, double-blind, placebo-controlled, cross-over study is to assess the short-term cognitive effects of a single dose (300 mg) of Mango Leaf Extract compared to a placebo on cognitive function, including during cognitively demanding task performance. The trial will utilise the COMPASS cognitive assessment system and cognitive demand battery (CDB), and Profile of Mood States (POMS), visual analogue mood scales (VAMS), and Stress Visual Analogue Scales (S-VAS) with assessments taking place at baseline, 30 minutes, 180 minutes and 300 minutes post treatment, on two separate testing days separated by 7 days (minimum).
This pilot study is a randomized control trial to test the effects of a 14-week home-based virtual, interactive high intensity interval training (HIIT) exercise intervention on cardiometabolic and cognitive outcomes in sedentary youth with overweight/obesity during adolescence. All participants (N=24) will complete screening via phone to determine eligibility. Eligible participants will be randomized to receive a) 14 weeks of a home-based HIIT intervention delivered via iPad or b) 14 weeks of a stretching intervention (control group). Each participant will undergo an in-lab pre- and post-test visit, where they will complete a fasting blood draw, a fitness test, and various cognitive and mental health measures.
Cognitive impairments such as memory impairments, word-finding difficulties, compromised orientation and perception are often observed in stroke patients. Low serum-mg-concentrations are associated with cognitive impairments in ischemic stroke patients one month after stroke onset. It is not clear, if cognitive impairments after stroke is caused by the mg-deficiency or by the stroke itself. Until now, no studies investigating the relationship between mg-concentration, stroke severity and cognition during treatment course are available. Thus, this study aimed to investigate the relationship between mg-concentration and cognition of stroke patients.
The aim of this project is to evaluate the effect of a dynamic light in order to improve the circadian rhythm, provide a better sleep and well-being, and in the long run an improved recovery. The primary question is whether dynamic artificial light with circadian stimulus can affect the circadian rhythm. The secondary question is whether this also provides better sleep and well-being. The group that is particularly interesting to study is a geriatric population that is more sensitive to circadian rhythm disorders, sleep disorders and confusion in connection with hospitalization and that can be of particular benefit from this intervention.
Introduction Both Mental Fatigue (MF) and hypoxia impair multiple aspects of cognitive functioning. The decline in cognitive functioning in hypoxic conditions is associated with alterations in brain oxygenation and hemodynamic responses. These hemodynamic responses are preferably measured at the prefrontal cortex, an area of the brain that is known for its executive function and role in decision making, planning, attention and (short-term) memory. This study will investigate the role of prefrontal cortex oxygenation during the development of mental fatigue and during cognitive performances by altering the ambient oxygen availability through normobaric hypoxia (3800m; 12,9% O2) and normoxia. Methods Subjects will perform four trials in a sound-insulated climate chamber (20°C and 40% RH). Upon entry in the climatic chamber participants will adapt to the environment for 30 minutes. Next, they will perform a modified cognitive test battery "cognition", a fine motor task "Motor Performance Series" and a visuomotor-fitlight task before and after a 60-minute individualized Stroop task or control task (randomized. blinded, placebo controlled, counter-balanced, cross-over design). Nearinfrared spectroscopy (NIRS) will be used to assess hemodynamic changes (oxygenated hemoglobin (O2Hb), deoxygenated-hemoglobin (HHb) and total hemoglobin (tHb)) at the PFC. Hypotheses 1) MF will lead to earlier changes in the prefrontal NIRS-parameters (O2Hb, HHb, tHb) with lower oxygen availability. 2) The effects of MF on cognitive performance manifest itself to a greater extent with lower oxygen availability.3) Visuomotor performance declines to a greater extent due to MF with lower oxygen availability.
This project uses a hybrid trial design to evaluate two biomedical interventions targeting the gut-brain axis. One intervention is portable Transcutaneous Vagus Nerve Stimulator, tVNS, that is hypothesized to stimulate the autonomic nervous system, resulting in decreased inflammation and improved cognition. The second intervention is a probiotic supplement intended to replace gut bacteria that are associated with dysbiosis in persons with HIV and alcohol consumption.
The objectives of this study are to investigate the effect of fruit consumption on the gut microbiota and their collective fecal and plasma metabolomes, vascular and cardiometabolic functions, cognition, and motor control.
