Background: Arterial disease of the legs causes symptoms such as pain when walking and may ultimately lead to a leg amputation. Many older people with arterial disease of the legs also have problems with their thinking and memory. Blood flow in the brain may be altered in these people and may be a cause for memory and thinking problems. Aim: The aim of this project is to investigate whether people with arterial disease of the legs have altered blood flow in the brain causing problems with memory and thinking. Research plan: Twenty people with arterial disease of the legs causing pain while walking and twenty healthy people will have a series of non-invasive assessments. Arterial disease in the legs will be measured using ankle blood pressures before and after walking. Blood flow in the brain will be measured using ultrasound whilst performing memory and thinking tests. Results will be compared between the people with arterial disease in the legs and the healthy people to see if there are any differences in blood flow to the brain and memory and thinking. Benefits to society: This project will help determine if there is a link between arterial disease of the legs and memory and thinking problems caused by altered blood flow in the brain. It will enable future research in people with cognitive impairment caused by altered blood supply to the brain and to prevent confusion and further memory and thinking problems in people undergoing surgery for arterial disease of the legs.
To assess the effect of Dexmedetomidine on serum Tau-217 protein and its relation to the incidence and severity of postoperative cognitive dysfunction in elderly patients undergoing major surgery under general anesthesia.
In recent years, globally, there has been a growth in both the size and the proportion of older adults in the world population. The World Health Organization (WHO) has estimated that by 2030, 1 in 6 people will be 60 years of age or older, and that by 2050, the population of older adults will reach 2.1 billion. The population of older adults (over 80 years) will triple to 426 million by 2050. In particular, Italy represents the second country with the oldest population in the world. Age-related evolution is a gradual and continuous process involving a series of physical and cognitive changes, which, however, has no real 'onset' age. In fact, rather than chronological age, the concept of 'elderly' is based on the individual's degree of self-sufficiency and independence. From a biological point of view, ageing is the set of changes at the molecular and cellular level that occur over time and lead to multi-system functional impairment. It is a process directly related to frailty, falls, and disability. An important factor in counteracting frailty is nutritional intake. Humans ingest approximately 500 g of chemical compounds daily through their diet, most of which are components of plants or vegetables in general. In addition to the well-known macronutrients (proteins, fats, and carbohydrates) and micronutrients (minerals and vitamins), the plant world provides other elements, such as phenols, terpenes, terpenoids, alkaloids, purines, pyrimidines, nucleic acids, and steroids, that exert powerful biological activities. These components are generically called phytochemicals. Epidemiological studies have established that diets rich in plant-based foods help prevent many diseases, such as cardiovascular, metabolic, neurovegetative, and inflammatory diseases. Phytochemical compounds are an extremely diverse set of elements that, when taken at significant levels, have a protective effect on human health. These substances exert various biological functions, such as antioxidant activity, modulation of detoxifying enzymes, stimulation of the immune system, reduction of platelet aggregation, modulation of hormone metabolism, reduction of blood pressure, and antibacterial and antiviral activity. Among the phytochemical compounds, flavonoids represent a category of polyfunctional substances with high bioactivity, comprising more than 5000 compounds. They possess biochemical properties of functional interest in the nutritional and therapeutic fields; for example, rutin, diosmin, and hesperidin are present in some pharmaceutical specialties; flavonoids from ginkgo biloba, hawthorn, and red vine are the main components of many phytotherapeutic extracts. Flavonoids have been shown to play an important role in cardioprotection. Furthermore, in neuroprotection, anthocyanin-rich fruits play a protective role against age-related decline in cognitive functions. However, few studies have evaluated the effect of hesperidin and proanthocyanidins on motor, cognitive, and functional aspects in the elderly. Altemor® is a food supplement based on micronized diosmin, hesperidin, and herbal extracts that has an important integrative supporting action in optimising blood microcirculation. The aim of the study is to evaluate the contribution of dietary supplementation with Altemor® on cognitive function, balance, fatigue, and some domains of quality of life in elderly subjects.
The purpose of this research is to determine the extent to which oculomotor function accurately detects THC-impairment, if cannabis use experience impacts this detection threshold, and to examine how the oculomotor index corresponds to a measure of sustained attention. A double-blind, placebo-controlled, within-subjects crossover design will be used to examine the dose-effects of THC (0, 5mg, 30mg) on oculomotor performance tasks and a sustained attention task in frequent and infrequent cannabis users. Results from the study will advance the investigators' understanding of the effect of THC and cannabis use frequency on oculomotor function and sustained attention, and will directly inform the validity of the investigators' oculomotor platform for identifying acute THC- induced impairment in frequent and infrequent users.
Pentoxifylline can improve cognitive impairment after ischemic stroke, possibly by improving the level of cerebral blood flow, affecting the content of blood oxygen and metabolic substances in the brain, and then playing a protective role in the transmission of nerve electrical signals, and ultimately improving cognitive function. The patients with cognitive impairment and non-dementia PSCIND after ischemic stroke were randomly divided into two groups. In addition to the basic drugs of ischemic stroke, the patients were given pentothemine sustained release tablets and blank control respectively to observe the effects of pentothemine on cognitive function and neuronal electrical signals in the patients with ischemic PSCIND. It is expected to explore the possible internal biological mechanism by using transcranial Doppler, oxygen-dependent functional magnetic resonance imaging and craniocerebral magnetic resonance pop analysis. Finally, statistical correlation analysis was used to elucidate the specific mechanism of pentoxifylline in improving cognitive function of non-dementia patients with cognitive impairment after ischemic stroke.
This study investigates the potential relationship between prior concussions and their impact on both vestibular function and cognitive abilities in athletes participating in sports.
Person-centred care can be supported when healthcare professionals access and actively use the information recorded in a life story. Active use of the life story can create security for a person with dementia and their carers. The written life story describes the person and their life experiences, which can define the person's identity. National guidelines for care and nursing in dementia and Blekinge's regional guidelines emphasise the importance of care and nursing for people with dementia, which should be given with a person-centred approach, where the life story becomes a tool for healthcare professionals. Research shows that a life story can be designed in several ways. For example, in book form, as a brochure, collage, memory box or electronically. The life story is also intended as a tool for healthcare professionals to create security and facilitate communication with the individual. As more and more older adults are using computers and tablets as assistive devices, and it is also becoming more common for healthcare professionals to use, for example, tablets as assistive devices in nursing care, the life story could be shared in digital form as an application and become a living document. Overall aim: To test an application for the life story with the intention of supporting person-centred care for older adults with dementia and to test whether the application can replace the written completion document. Study I: Exploring the research area of the life story in digital form. Study II: Focus group interviews with healthcare professionals. Study III: Test the application, Min Memoria. Study IV: Observations on the use of the application.
