Filter by: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.
Cognitive impairment is a common complication in diabetes for various reasons. Although glycemic control improves cognitive impairment, different antidiabetic medications' effects on cognitive functions are still being investigated. Brain-derived neurotrophic factor (BDNF) is a neuroinflammatory marker and a member of the neurotrophin family with growth factor properties. BDNF levels have been shown to decrease in mild cognitive dysfunction or in late-onset Alzheimer's disease. Our aim is to examine the effect of SGLT2 inhibitor use on cognitive functions and BDNF levels.
Randomized Controlled Trial (RTC) testing the efficacy of a telehealth adaptation of the Cognitive-Remediation of Executive and Adaptive Deficits in Youth (C-READY) intervention to prepare adolescents with sickle cell disease for transition of care.
The purpose of this research study is to determine whether istradefylline improves cognition in individuals with Parkinson disease with cognitive impairment.
The present study aimed to investigate the effects of a Virtual Reality cognitive training intervention (VRCTI) on cognitive function changes measured with a cognitive test battery and improvement of quality of life in older adults with cognitive impairment in long-term care facilities. Weekly 1-hour sessions were implemented over 8 weeks targeting sustained and selective attention, memory, cognitive functions, and rule deduction. The passive control group received usual care.
In the United States, more than a million people sustain a mild traumatic brain injury (mTBI) every year. Although many recover fully, emerging literature suggests a high number of individuals report chronic, and functionally disabling, cognitive difficulties. Among Veterans, a nationwide survey found that more than 75% of 55,000 Veterans with a history of mTBI reported persistent moderate to severe levels of forgetfulness and poor concentration. Reduced cognitive functioning following mTBI contributes to significant functional impairment, including underemployment, relationship difficulties, and reduced community integration for years post injury. Despite the significant individual and societal impact, evidence to guide interventions and treatment for this population remains limited. Even more limited are validated telehealth options for these symptoms, a critical means by which access to care can be improved, especially during the COVID-19 pandemic. The proposed pilot study will address this gap by evaluating the feasibility, acceptability, and preliminary effectiveness of a brief (5-session) cognitive rehabilitation intervention that was developed for individuals with mTBI and that will be administered over video-based telehealth technology. The development of this intervention was supported by a grant from the Department of Defense, with critical elements identified through surveys completed by clinicians and veterans with a history of mTBI, and also the clinical expertise of the team.
Alzheimer's disease and related dementias (ADRD) are serious, life limiting illnesses with no known cure. Dementia is the fifth-leading cause of death in older adults and the majority of people with advanced dementia die in nursing homes (NHs). Miller et al reported that 40% of U.S. NH residents dying with advanced dementia received Skilled Nursing Facility (SNF) care in the last 90 days of life, and receipt of this care was associated significantly with poorer end-of-life outcomes, including a higher risk of dying in a hospital, compared to decedents with no SNF care. SNF care is a Medicare post-acute rehabilitation service delivered in NHs focused on intense rehabilitation and/or aggressive, disease-modifying therapies. Regardless of life expectancy, use of SNF care precludes access to Hospice services. Palliative care (PC) offers an evidence-based alternative.
Traumatic brain injury (TBI) is an important global health concern. Recently, advances in neurocritical care have led to an increase in the number of recovering TBI patients, and concomittantly in the incidence of complications of TBI. One of the most important sequalae of TBI is cognitive deficit, for which multimodal rehabilitation approach is indicated. Transcranial direct current stimulation (tDCS) is a promising treatment strategy for post-TBI cognitive deficits. However, a standardized tailored tDCS protocol is yet to be established for TBI patients. Therefore, this trial aims to 1) the efficacy of tDCS on post-TBI cognitive deficits, and 2) and optimized protocol of tDCS on post-TBI cognitive deficits via a three-arm double-blind, randomized controlled trial.
The purpose of the study is to examine the properties of the Automatic Story Recall Test (ASRT) and its parallel variants, as well as letter fluency and category fluency cognitive tests. Tests will be completed in crowdsourced populations, to derive normative data, and examine test properties in demographically diverse and cognitively impaired participants recruited and tested online.
This implementation study will be conducted to test a Socially-Assistive Robot (SAR) system for residents in an Assisted Living environment. The goal of the SAR system is to enhance social engagement and connectedness. The system engages residents via robot-facilitated activities such as trivia and reminder and is integrated with the SimpleC Wellness Platform.
