Filter by:Currently almost 5 million Americans suffer from the distressing symptoms related to dementia and this number that will triple by 2050. The overall goals of the proposed project are to evaluate, in community dwelling Alzheimer's Disease Research Center participants the benefits of a 12-month nurse-led early palliative intervention on symptoms, quality of life, health care resource use. The relevance of this research to public health is that there is an urgent need to improve the palliative care of persons with dementia living in the community. This study will contribute substantially to that effort.
This is a prospective observational study, that investigates men diagnosed with testicular cancer before and after treatment. The patients are included at their visit at the Fertility clinic in Horsens, where they deposit semen for cryopreservation prior to surgery and potential systemic treatment. Here the patients, who want to participate will perform a cognitive test and afterwards complete a questioner (T1). After 9 month the patients will be invited to perform the cognitive test and complete the questionnaire again (T2).
Alzheimer's Disease (AD) is characterized by amyloid-β (Aβ) plaque buildup and phosphorylated tau (p-tau) in the brain, as well as widespread neurodegeneration. Amyloid-β and tau are proteins that build up in the brain that may contribute to memory problems. The evidence suggests that both amyloid and tau play a critical role in AD and interventions that reliably and safely decrease the intracerebral burden of amyloid or tau could potentially be of marked clinical importance. Currently, therapeutic options are very limited and while there are pharmacologic interventions that transiently improve cognitive function, there are no treatments that alter disease progression. The purpose of this study is to see if multiple daily sessions of non-invasive brain stimulation can affect brain activity to decrease the amount of amyloid and tau in people with AD as compared to Sham (placebo) stimulation. The type of brain stimulation that will be used is called transcranial alternating current stimulation (tACS). This study will investigate different doses of tACS (2-4 weeks) and assess safety. The hope is that tACS will decrease the amount of amyloid and tau and improve memory and thinking in people with AD.
This study aims to assess the therapeutic role of rTMS on parkinson's patients with cognitive impairment. Patients diagnosed with Parkinson's Disease and cognitive impairment will be recruited. All patients will be admitted and will be allocated randomly into two groups one of which will receive real sessions of high frequency rTMS for each hemisphere for 10 consecutive sessions totally over period of 10 days with repeated booster sessions every month during the period of follow up. The other will receive sham sessions.
In the DEMAND pilot study, we will recruit and randomize 80 participants at two study sites (Umeå and Uppsala) for a one-year intervention. The primary objectives are to study the inclusion rate, the adherence rate, and the acceptability of the intervention. The secondary objectives are to examine the effect of the intervention on intermediate outcomes, including metabolic control (i.e., blood glucose and lipids), body weight, blood pressure, physical fitness, and cognitive function. Third, the investigators will perform focus group interviews to explore the participants views on the intervention to assess the acceptability. The interventions include (a) Mediterranean diet (b) an individualized physical training program and (c) pharmacological treatment for type 2 diabetes (T2D) aimed to achieve individualized optimal goals, according to national guidelines, taking into account the risk of hypoglycaemia. This multi-component intervention is more comprehensive than usual care, and it specifically focuses on vascular domains.
The aim of this study is to explore the relationship between cortical hyperexcitability, abnormalities of brain network function, and cognitive dysfunction in human patients with AD and whether administration of the antiepileptic medication levetiracetam (LEV) normalizes these measures and improves cognition.
This study will test the effects of different doses of a form of non-invasive brain stimulation for the treatment of individuals with mild cognitive impairment (MCI) and dementia of the Alzheimer's Type (DAT).
This is a pilot study at the University of Alabama at Birmingham. The purpose of this initial study is to test how effective a new therapy is for improving participants ability to think, particularly how rapidly they process information that they receive from their senses, e.g., sight, hearing,… . The study will also test whether the new therapy improves how often and how well they are able to carry out tasks that rely on thinking in their daily life. The therapy will combine a computer game that ask participants to identify targets on the screen as rapidly as possible with a set of psychological techniques that will help to apply the improvements that are made in how rapidly participants process information as a result of the game to carrying out tasks that rely on thinking in your daily life.
Problems with blood sugar metabolism (i.e., metabolic dysfunction) progressively develop through old age, which is primarily due to obesity and lack of physical activity. Metabolic dysfunction increases the risk for Alzheimer's disease (AD) and negatively impacts memory and related brain function. There is intense interest in developing interventions, particularly non-drug therapies, to combat AD. Recent clinical trials have found that intranasal insulin, which facilitates glucose metabolism in the brain, is able to maintain memory in participants with Mild Cognitive Impairment (MCI), the precursor to AD. While intranasal insulin is a useful, proof-of-concept intervention, it does not affect visceral fat mass and therefore metabolic dysfunction will persist in a given person. The investigators wish to engage participants with MCI in intermittent calorie restriction (CR), to reduce metabolic dysfunction and improve glucose metabolism. Intermittent calorie restriction in this case refers to eating whatever one wants for 5 days, followed by 2 consecutive days of consuming 530 calories via one protein shake with sufficient nutrients to sustain the person. This results in reliable weight loss, which itself improves glucose metabolism in the body and has a wealth of other benefits. (It should be mentioned here that weight maintenance has been shown in studies when participants restrict to 1 day/week).
People living with subjective cognitive decline (SCD) or mild cognitive impairment (MCI) experience less efficiency in performing complex everyday tasks, which may result in a general sense of discontentment and decreased satisfaction with their overall functional performance. Additionally, SCD and MCI have been associated with concomitant anxiety, depressive mood, perceived stress, a decrease in emotional well-being and quality-of-life (QoL) among community-dwelling older adults. These concomitant psychosocial issues may result in emotional distress which further exacerbates cognitive decline. At the present time, there is a lack of evidence that supports pharmacologic interventions to ameliorate concomitant psychosocial issues with this particular population due to medication side-effects, drug-drug interaction and polypharmacy. Consequently, exploring alternative non-pharmacological interventions to assist in ameliorating psychosocial issues is an important consideration. Secondly, evaluating perceived satisfaction on functional performance with those living with SCD and MCI, and assessing interventions that may support this is also worthwhile to pursue. Primary care providers are often the first point of contact when older adults and their families become concerned about memory problems. Health care professionals, on an interdisciplinary Family Health Team (FHT), such as occupational therapists, are well-positioned to holistically address both the psychosocial and functional needs in a client/family centred way with this growing population in primary care. The study proposes to offer a Mindfulness-Based Stress Reduction (MBSR) program, which is an 8-week program that has been shown to be beneficial in alleviating emotional distress among adults living with physical and psychological issues in the general population.
