Filter by:In the study titled Operational Ground Testing Protocol to Optimize Astronaut Sleep Medication Efficacy and Individual Effects (Phase 11), two randomized , blinded , placebo-controlled , cross-over trials will be conducted. The hypnotic medication and the placebo will be indistinguishable by subjects. Experiment 1 will involve N=14 subjects randomized to placebo , 10 mg Zolpidem (Ambien) and 10 mg Zaleplon (Sonata) in counterbalanced order and will be awakened 90 min. post-placebo administration (half at 60 min and half at 90 min). The latter will be done to maintain some degree of blinding relative to the participants knowledge of conditions and the staff working on the protocol. Zolpidem is the most commonly , and Zaleplon is the second most commonly , used sleep aid medication used in spaceflight. Females and those subjects who have had a previous adverse experience with 10 mg zolpidem will be placed into Experiment 2, which will involve N=20 subjects randomized to placebo , 5 mg zolpidem and 10 mg zaleplon. Data acquisition for both experiments will occur in the Astronaut Quarantine Facility ("AQF") at Johnson Space Center (JSC). Experimental methods and cognitive outcomes will be the same as those used in the pilot investigation titled Develop and Implement Operational Ground Testing Protocols to Individualize Astronaut Sleep Medication Efficacy and Individual Effects (Phase I). Combined , Experiment 1 and 2 will provide data on zaleplon 10 mg compared to placebo on a total of 34 subjects consisting of astronauts and other subjects considered analogous to the astronaut population (e.g., Flight Controllers, Flight Directors , Flight Surgeons, medical residents and medical students on National Aeronautics and Space Administration (NASA) rotation, and NASA/contractor employed University of Texas Medical Branch physician's) , which will provide the larger sample needed to identify those subjects who have cognitive performance deficits on abrupt awakening to the less sedating 10 mg zaleplon.
The purpose of this study is to learn how foods high in polyphenols and brain training exercises affect older adults' cognitive performance
Little is known about preventive strategies with immediate public health impact for cognitive functioning in the oldest-old (OO). Cognitive training improves cognitive functioning in the young-old (YO; 60 to 84), yet has not been examined in the OO. Clinical trials are needed to determine if computerized cognitive training is effective at preventing or delaying cognitive decline in the OO. In order to develop such trials, information regarding use of computers and internet by the OO, and the ability and interest in such a program, must be determined. This study will examine the effects of a computerized cognitive training program, CogniFit™, with a "classic" computerized games program, on cognitive functioning in cognitively healthy OO subjects. Information regarding use of computers and internet by the OO will be collected. Interest in and ability to complete a computerized cognitive training program will be examined, along with the cognitive, demographic, biological, and lifestyle characteristics related to this interest and ability. Efficacy of the CogniFit™ and games programs will be assessed immediately following the training and four months after completing the training. The researchers expect that those who use the CogniFit™ program will have greater improvements than those using the games program. Finally, the participants' characteristics related to the efficacy of the programs will be examined. Subjects recruited for this project will include those already participating in several studies of aging and cognition at the Mount Sinai School of Medicine. Recruiting from this pool of subjects will provide this program with baseline information regarding numerous subject characteristics, including cognition, family history, lifestyle, and cardiovascular information. This study will inform future large-scale clinical trials of computerized cognitive training programs in the elderly, as well as provide information regarding the efficacy of such training in the OO. In addition, the study will identify characteristics affecting efficacy of computerized training, and thus, may suggest mechanisms through which cognitive training improves cognitive functioning in the most senior citizens of our society.
A strategy involving 6 partners was planned, targeting the components of education, innovation, and practice-based research with knowledge transfer into clinical practice.The project MIND&GAIT aims to promote independent living in frail older people through the development of innovative initiatives and systems to improve cognition and gait ability. A structured and integrated Combined Intervention (CI) will be developed, composed by: cognitive stimulation program, an animal-assisted therapy program, a physical activity program. Moreover, an auto-blocking mechanism for rolling walkers will be developed and implemented in this study. The results of the study and all the material that was used, will be disseminated in a web platform.
Studies have found a beneficial effect of tea consumption on the reduction of risk of cognitive impairment and dementia in older aged populations. However, there is a paucity of data on these associations in the very old defined as individuals aged 85 years and over. Therefore, we hypothesized that higher tea consumption was associated with better global and domain-specific cognitive function. We investigated the relationship between tea consumption in the very old and measures of global cognitive function, memory, attention and psychomotor speed. The Newcastle 85+ Study was a longitudinal (5-years), population-based cohort study of individuals aged 85+ years in North East England, United Kingdom. The final sample included 676 community-dwelling and institutionalized men and women recruited through general medical practices. Baseline tea consumption was assessed through a 2x24-hr multiple pass recall and longitudinal measures of global and domain specific (memory, speed and attention) cognitive function through the standardized mini-mental state examination and the cognitive drug research system. Linear mixed models, controlling for demographic (e.g. age, sex and education) and health variables were used to determine whether tea consumption was protective against cognitive decline.
Phase 1: This is a remote observational study in which participants will complete cognitive assessments developed by Posit Science. Participants will be healthy controls aged 18-65 with reliable internet access and a device that they can use to access the assessments, such as a laptop or iPad. Participants will complete up to 6 Posit Science assessments in different domains of cognition, which should last approximately 30 minutes. Phase 2: This is an in person observational study in which participants will complete cognitive assessments developed by Posit Science. Participants will be healthy controls aged 18-80 who are fluent in English. Participants will complete batteries of cognitive assessments developed by Posit Science, which include combinations of visual, auditory, and social cognitive assessments, and self-report questionnaires. This study will be conducted at the Driven to Discover building at the Minnesota State Fair. Participation will last approximately 20 minutes. Phase 3: Participants in Phase 3 will complete a Posit Science assessment battery and self-report questionnaires. Each participant will be asked to provide brief demographic and medical history data. Participants will be aged 18-35 and will be students at the University of Minnesota who are enrolled in the Research Experience Points program. Participants will complete the assessment battery remotely; the battery will take approximately 45-60 minutes to complete. Phase 4: This is a pilot program to test the use of remote cognitive assessment and training in adolescents with an anxiety diagnosis and healthy controls. Participants will complete a short assessment battery, then will receive 4 hours of cognitive training over 2 weeks at home. Then they will repeat the battery. Total participation should last approximately 5 hours over 2-3 weeks and will be completed entirely remotely.
The high prevalence of cannabis and other substance use disorders are a major barrier to recovery in people with schizophrenia. Moreover, schizophrenia patients have significant deficits in cognitive function, which may be exacerbated by cannabis use. Complicating these problems is the lack of evidence-based treatments for co-morbid cannabis use disorders (CUDs) in schizophrenia; there are no established pharmacotherapies. Therefore, this study is investigating the effects of high-frequency (20Hz) repetitive transcranial magnetic stimulation (rTMS) on cannabis use disorder and cognitive function in patients with co-morbid schizophrenia/schizoaffective disorder. The proposed study would be the first randomized, double-blind, sham controlled trial of rTMS in patients with schizophrenia and co-morbid CUD. A total of N=40 schizophrenia smokers with co-morbid cannabis use disorder will be assigned to either active rTMS (N=20) or sham rTMS (N=20) as a treatment regimen of 5X/week treatment for four consecutive weeks. All participants will receive weekly behavioral therapy for 4 weeks. The investigators predict that active rTMS will be well-tolerated and superior to sham rTMS for the treatment of CUD in schizophrenia.
The deleterious effects of obesity on cardiovascular disease (CVD) and metabolic risk factors (dyslipidemia, hypertension, and insulin resistance) are well-documented. Recent evidence also links obesity to cognitive decline and dementia. Dietary patterns are central to the development and maintenance of obesity and certain dietary patterns may contribute to the onset and progression of cognitive decline. With the rapid aging of the US population and the high prevalence of obesity among older adults, innovative lifestyle strategies to prevent cognitive decline among ethnically diverse obese older adults are critically needed.
The goal of this study is to determine if supplementation with krill oil concentrate containing the phospholipid-bound omega-3 fatty acids improves performance on specific cognitive tests that underlie key elements in U.S. Army Infantry Basic Officer Leaders Course (IBOLC) and in Ranger School (Training) at Fort Benning, Georgia (GA).
The aim of this study is to determine whether drinking plain water when mildly dehydrated benefits cognitive performance and mood. Volunteers undergo a dehydration protocol designed to result in minor dehydration. While some participants receive two 150ml drinks of water others do not. Differences in cognitive functioning are assessed.
