Filter by:The novel coronavirus SARS-CoV-2 infection, COVID, continues to rage throughout the world with 115,000,000 confirmed cases and over 2,500,000 deaths (as of Mar 3, 2021). This translates to millions of people surviving COVID19 infection. While the lungs are ground zero, COVID tears through organ systems from brain to blood vessels. We are now beginning to see people recover but complain of ongoing problems, including lingering cognitive problems, depression, and anxiety. We have brought together 2 laboratories with complementary techniques including psychological testing and neuroimaging methods togethers with markers in the blood that may signal damage in the brain. A close look at these problems is timely and imperative if we are to understand the pathophysiology of 'COVID brain' and prepare for downstream problems.
Subjective memory complaints (SMC), the main cognitive component of which is event memory, is a predictor of Alzheimer's disease in elderly people. The purpose of this study was to investigate the effect of transcranial alternating current stimulation (tACS) with theta frequency (6 Hz) on the medial prefrontal cortex in the improvement of episodic memory in individuals with SMC in a double blind, randomized, and sham-controlled parallel study. Sixteen participants with SMC received either active or sham theta tACS on the medial prefrontal cortex (mPFC). EEG was recorded and Rey Auditory Verbal Learning Test (RAVLT) was administered. The aim of the current study was to see if theta tACS over the mPFC can improve event memory in individuals with SMC and thus can be considered a potential therapeutic intervention for this population or not.
The Smart Supplement has 20 vitamins and minerals that have strong track records of demonstrating positive health effects, both physiologically and cognitively. This twelve-week trial will examine the effectiveness and efficacy of Heights Smart Supplement on both biomarkers and subjective experiences from participants.
Providing a combination of synergistic dietary supplements, such as vitamins B6, B12, and folate, as well as curcumin, lemon balm, and American ginseng is hypothesized to promote brain health and aid with brain fog, mental clarity, ability to handle stress, mood, focus, and productivity, as well as promote overall well-being.
The aim of this project is to estimate the effects of therapy with dance and movement and Tai Chi on irisin plasma levels, a myokine with proven neuroprotective effects, in the context of baseline levels of cognitive function and physical performance in seniors over 65 years of age. It is empirically verified that physical activity can have a positive effect on cognitive function even in individuals with mild cognitive impairment. There may be a number of reasons why this is the case. Recently, research investigating the relationship between the secretion of certain myokines and their neuroprotective effects has gained importance. One of these myokines is irisin, which has recently been shown to have beneficial effects on the CNS by upregulating the expression of Brain Derived Neurotrophic Factor (BDNF) in the hippocampus in an animal model. Increased irisin levels as a consequence of exercise have recently been partially demonstrated in humans. What type of physical activity is most effective in terms of its effect on cognitive function in humans is another important scientific challenge. The possibility of influencing endocrine secretion of bioactive substances with proven effects on synaptic plasticity, neurogenesis and neuroprotection through effective therapies may help to combat neurodegenerative diseases, the prevalence of which is increasing with the average age of the population. According to Alzheimer's Disease International, 50 million people worldwide were affected by some form of neurodegenerative disease in 2017. The number of people affected is still rising. It is predicted that this number will reach 75 million sufferers by 2030 (https://www.alz.co.uk/research/statistics). Alzheimer's disease and multiple sclerosis are the two most common manifestations of neurodegenerative diseases. The effect of therapy with dance and movement and the effect of Tai Chi on blood irisin levels in the context of cognitive function and physical performance levels, has not yet been conclusively demonstrated.
To determine the effects of moderate intensity exercise and caffeine on working memory in deprived caffeine consumers.
The goal of this project is to develop probiotic dietary supplements intended for the elderly, which can modify the composition of the intestinal microbiota typically occurring in the aging population. According to currently held scientific knowledge, it is postulated that the probiotics-induced normalization of the physiological axis in the brain-intestinal microbiota affects the activity of the nervous system. Thus, normalization of this axis should lead to observable improvements in cognitive functions and quality of life.
The investigators plan to investigate the effect of enhancement on working memory (WM) in patients of chronic schizophrenia and determine the predictive factors of effective treatment.
This study was designed to characterize the changes in the brain and body associated with whole coffee cherry extract (WCCE). WCCE is a patented extract of whole coffee fruit (coffee berries) from coffea arabica. Whole coffee cherries are a source of naturally occurring nutrients. There are no known side effects or allergens associated with WCCE other than that which would be associated with a consuming typical cup of coffee. Previous studies suggest that increases in serum concentrations of both serum total and exosomal brain-derived neurotrophic factors (BDNF) may represent one of the mechanisms responsible for improved cognitive function after acute WCCE administration. Mild cognitive impairment (MCI) is an intermediate stage between the expected cognitive decline of normal aging and the more serious decline of dementia. It can involve problems with memory, language, thinking and judgment that are greater than normal age-related changes. Furthermore, MCI is associated with reduced circulating BDNF. Due to earlier studies reporting the ability of WCCE to stimulate increases in circulating and exosomal BDNF, it has been postulated that WCCE may also acutely improve cognitive function (as measured using behavioral tasks and fMRI). The purpose of this study is to extend and elucidate the findings of previous investigations by examining the acute neurophysiological effects of WCCE using blood-oxygen level dependent (BOLD) functional magnetic resonance imaging (fMRI) and magnetic resonance spectroscopy (MRS) employing a double-blind, randomized crossover design to investigate the acute effects of a single dose of WCCE or placebo (silica oxide) on neuronal activity in older participants.
The proposed study will evaluate the safety, durability and efficacy of repetitive Transcranial Magnetic Stimulation (rTMS) as a promising non-invasive therapeutic treatment for improving memory in older adults with mild or moderate Traumatic Brain Injury (TBI) who have been experiencing residual memory or cognitive problems that affect daily functioning.
