Filter by:The purpose of this study is to develop and implement a culturally-appropriate intervention to reduce stress in Vietnamese dementia caregivers. A pilot intervention will be done to test the feasibility and acceptability of the intervention in a community setting. This will be done by randomly assigning a family triad (primary caregiver, secondary caregiver, and their care recipient) into an active intervention or a control condition and monitoring findings at baseline, post-intervention, and at three months.The intervention will consist of multiple components -enhanced psycho-education that includes discussion of Alzheimer's Disease (AD) and cultural impacts on beliefs about dementia and caregiving, management of problem behaviors, facilitation of support seeking, and mindful Tai Chi. A secondary caregiver who the primary caregiver identifies as providing him/her with the most support will be invited to join all components, but the intervention will be flexible depending on caregivers' needs/preferences. The care recipient is not required to join the sessions but will be able to if he/she or the family wishes. During the intervention, community partners will provide respite care for the care recipient.
This study will investigate the effect of Repetitive transcranial magnetic stimulation (rTMS) on cognition and long-term clinical outcomes of bipolar patients.
The purpose of this study is to evaluate if systematic cognitive training can improve cognitive performance in participants (55 and older) with memory loss. This study will evaluate the effects of Computerized Cognitive Training (CCT) for improvement in everyday cognitive and function status, in addition to long-term changes in brain networks over an 18-month period. Although there is no distribution of medication for this study, participants are required to have an at-home computer.
Prospective trial of low frequency deep brain stimulation of the ventral subthalamic nucleus to improve cognitive performance in patients with advanced Parkinson's disease. All study participants have undergone DBS implantation surgery as part of their routine care for motor manifestations of Parkinson's disease. In this study, a temporary low frequency period of stimulation will be applied to determine its effects on cognition.
Purpose:To gather preliminary data and to determine the feasibility and acceptability of an 8-week Tai Chi intervention for adults cancer survivors (survivors) who report experiencing cognitive impairment, and to perform exploratory analyses to assess improvements in cognitive performance, health-related quality of life, brain activity, and blood-based biomarkers. Participants: Adult survivors (> 18 years old) who report experiencing cognitive impairment and are within 60 months of completion of chemotherapy for treatment of a breast cancer diagnosis. Procedures (methods): A single arm pre-/post-test non-randomized study design in adult cancer survivors (Enrollment goal N=15; current age ≥ 18 years, treatment completed within 60 months). Outcomes will be assessed at baseline and after the 8-week Tai Chi intervention, and consist of feasibility, acceptability, expectancy/credibility, health-related quality of life, cognitive performance, serum biomarkers, and brain activity.
This study will evaluate the feasibility of delivering a supervised physical activity program plus standard exercise counseling (SPA+EC) versus a supervised physical activity plus motivationally-enhanced behavioral counseling (SPA+BC) in prostate cancer survivors (PCS). Fifty participants (n=25) will be randomized to receiving SPA+EC or SPA+BC (n=25). We hypothesize that PCS receiving the SPA+BC intervention will result in greater increases in objectively-assessed physical activity compared with PCS receiving the SPA+EC intervention.
This is a double-blind, placebo-controlled, crossover study testing whether Vyvanse (lisdexamfetamine; LDX) improves executive functioning (EF) in 100 postmenopausal women who report onset of EF difficulties after oophorectomy. This study involves magnetic resonance imaging (MRI) to see how LDX affects brain chemistry while undergoing two 6-week trials of the study drug and placebo capsules. UPDATE: We have recently updated this protocol (09/2020) to offer a remote version of the study that can be completed entirely from the participant's home. This alternate version of the study eliminates travel, the MRI, and blood draws.
This randomized phase II trial studies how well low-dose ibuprofen in improving cognitive impairment in patients with cancer. Anti-inflammatory agents, such as ibuprofen, may slow the decline of cognitive processes and diseases involving the brain.
Heart failure (HF) is the major cardiovascular disease that continues to grow in prevalence, largely due to aging of the population. HF is described as the inability of the heart to keep up with the demands on it and, specifically, failure of the heart to pump blood with normal efficiency. Cognitive impairment (CI) is common in HF patients, resulting in a person having trouble remembering, learning new things, concentrating, or making decisions that affect their everyday life. Patients with HF have been show repeatedly to have trouble remembering and learning new things when compared to the general population. Patients with demonstrated CI have a significantly increased risk of developing dementia (memory loss). It is believed that the reason HF patients have a higher risk of CI is possibly due to less blood reaching the brain and an overall inflammatory process occurring in the body including the brain. To date there are no known therapies that can help treat CI caused by HF. A substance, Angiotensin-(1-7) [Ang-(1-7)], is known to decrease inflammation in the brain. Early studies in humans have shown it to be safe. This substance is naturally produced in the body and works by activating areas in the brain involved in memory. Investigators believe that Ang-(1-7) may be able to help lower the risk of loss of cognitive function in patients with heart failure. In this study, we will try to determine whether Ang-(1-7) is a safe and effective treatment for cognitive impairment in HF patients.
Objectives: Investigate the acute NIV effects on CBF and cognitive functions in COPD patients. Methods: Nine non-hypercapnic stable COPD subjects (FEV1/FVC < lower limit of normal) and twelve healthy controls were enrolled. CBF (transcranial Doppler), cognitive functions, respiratory and cardiovascular response were tested at baseline, during and after non-invasive ventilation.
