Postoperative cognitive dysfunction (POCD) describes a condition where cognitive functions such as attention, perception, concentration, learning, abstract thinking and problem solving are impaired postoperatively. These changes can be resolved after weeks and months. In some cases, changes are permanent.
Cognitive training has emerged as a promising method to maintain, enhance, and rehabilitate cognitive function in older adults and individuals with dementia. In recent years, such training has become particularly appealing in the clinical context, with many paradigms aimed specifically at adults experiencing various stages of cognitive decline due to Mild Cognitive Impairment, Alzheimer's disease, and vascular dementias. However, basic questions remain. For example, uncertainty persists regarding factors that influence observed improvements as well as the conditions that would maximize transfer and sustainability of training effects. The objective of this study is to evaluate factors that may maximize the benefits of computerized cognitive training in older adults.
The purpose of the study is to determine the effect of an web-based intensive cognitive rehabilitation program in neuropsychological performance of a population of patients with multiple sclerosis or clinical isolated syndrome.
As recommended allowance of oral vitamine D are unable to ensure the recommended serum concentration of vitamine D, the purpose of this study is to show that a dose of vitamin D3 higher than the recommended allowance may slow the cognitive decline of patients with a memory complaint.
This prospective cohort study aims to determine if apparently healthy children with no significant co-morbidities who undergo general anaesthesia for minor surgery before 15 months of age will develop measurable deficits in neurocognitive development compared to apparently healthy children with no significant co-morbidities who do not undergo general anaesthesia or surgery.
Background: The increase in life expectancy and the rise in the ratio of older to younger people in the population has resulted in an increase in the number of those suffering from a decrease in cognitive ability, such as Mild Cognitive Impairment (MCI). Methylphenidate can improve cognitive ability, mainly in memory and executive function. Working hypothesis and aims: This study examines the effect of Ritalin treatment in older people suffering from MCI. Our hypothesis is that treatment with Ritalin will improve cognitive function in those suffering from MCI, especially in the domains of attention and executive function. Methods A randomized, double-blind, case-control study. 120 patients older than 65 years of age diagnosed as suffering from MCI in the past year in geriatric assessment facilities in Beersheva. Patients will be randomized in equal groups to either the study group (Ritalin treatment) and control group (placebo). Each participant will attend the geriatric unit for four consecutive days: on the day prior to beginning the intervention participants will undergo cognitive assessment at 9:00 am. On the intervention days (days 2-4) participants will undergo cognitive assessment at 9:00 in the morning, followed by the administration (at 10:30) of different doses of Ritalin (10, 20 and 30mg) every day of intervention. Participants in the control group will receive placebo. Two hours after taking the drug or placebo participants in both groups will be assessed cognitively by means of Mindstreams and MoCA (Montreal Cognitive Assessment). Expected results: Ritalin treatment will improve the cognitive function of the subjects, mainly in the domains of concentration and executive function
This research aims to help older African Americans with diabetes and mild memory problems improve how they take their medications and control their diabetes. This may preserve their independence and health, prevent cognitive and functional decline, and reduce health care costs. As the population ages and becomes more racially diverse, finding ways to achieve these outcomes has great public health importance.
Previous studies in animals and humans has shown that brief periods of reduced blood flow to one organ or tissue in the body can help protect other tissues from subsequent injury caused by reduced blood flow such as a stroke. This phenomenon is known as remote ischemic preconditioning and may help protect brain cells after a stroke. The investigators are studying a specific stroke type called subcortical stroke that is very common and has a high rate of recurrent stroke and cognition problems despite intensive prevention measures.
The aging US population threatens to overwhelm our healthcare infrastructure, especially since the rate of Alzheimer's disease (AD) alone is expected to triple in the coming decades. Memory cause functional impairment, reduced quality of life, increased caregiver burnout, and eventual institutionalization. The diagnosis of mild cognitive impairment (MCI) identifies those with memory deficits but who remain relatively independent in everyday life. MCI provides a window for interventions that target memory functioning. The proposed study focuses specifically on a groundbreaking combination of mnemonic rehabilitation and non-invasive brain stimulation. The main idea is that brain stimulation can enhance functioning in the specific brain regions/networks, thereby increasing the patients' ability to benefit from different types of memory rehabilitation. This will be a randomized, double-blind study (active vs. fake brain stimulation), that provides multiple treatment session. Outcome will be examined using both laboratory-based and real-world memory testing as well as brain imaging. This first-of-its-kind study has the potential to meaningfully translate more "basic" science findings into neuroanatomically targeted and functionally meaningful treatments for our aging population.
