A good quantity, and quality, of sleep is crucial for well-being. Evidence strongly indicates that poor sleep quality and quantity is causally involved in the development of dementia; therefore, techniques which can improve sleep in older adults are very likely to prevent or slow down the disease process in dementia. This project aims to manipulate a specific aspect of sleep in healthy older adults. This: 1) has the potential to prevent the pre-dementia stage of mild cognitive impairment in healthy older adults, and 2) has a direct clinical application to dementia. The overall aim of this project is to investigate if a non-invasive brain stimulation technique called transcranial direct current stimulation (tDCS) can enhance specific brain activity patterns during overnight sleep in healthy older adults. These brain activity patterns during sleep (called 'sleep spindles') are mechanistically linked to both the physiological restorative and the cognitive function of sleep. Sleep spindles can only be assessed by measuring overnight brain activity during sleep. Sleep spindles are very strongly associated with attention, and memory performance, which are severely affected by dementia. A decrease in sleep spindles is associated with cognitive decline, and predict dementia development. Therefore, enhancing sleep spindle activity in sleep is likely to boost cognition. Whilst previous research studies have demonstrated that in a sleep laboratory environment, tDCS can manipulate sleep spindles when individuals are in a specific brain state in a nap situation, we are specifically interested in testing tDCS in a home environment. This is because the use of tDCS in a home environment has have a number of advantages over sleep laboratory studies. Specifically, by conducting this study in a home environment, this will maximise the inclusivity of studies involving older adults, and DLB patients, since they will not be required to travel to a sleep laboratory to participate in studies. The aim of this proof-of-principle study is to investigate if tDCS can manipulate sleep spindles in healthy older adults. It is expected that relative to a placebo stimulation, active stimulation (which exerts an effect upon the brain) will increase sleep spindle activity in healthy older adults.
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.
Clinical investigation of a medical device (CAVA) for recording eye movements. Forty volunteers will sleep in a specially designed sleep lab for one or two nights, depending on whether they are enrolled onto phase 1 (two nights) or phase 2 (one night) of the study. Each volunteer will wear the CAVA device along with a Polysomnography (PSG) device, which is the gold standard for monitoring sleep. The twenty participants in phase 2 will simultaneously wear a commercially available consumer device for monitoring sleep. The eye movement data captured using CAVA will be processed by novel computer algorithms to classify the sleep stages in the data into Rapid Eye Movement (REM), non-REM and awake. The results will be compared with the ground-truth from the gold standard, and also compared to the results from the commercially available device. The aim of the study is to determine whether CAVA could be a viable and competitive home-monitoring device for analysing sleep.
