Filter by:The objectives of this study are to: (1) determine the effects of combinatorial training (i.e. combinatory of aerobic exercise with cognitive training and guiding training) vs. the sequential training (i.e. a combination of aerobatic exercise with cognitive training) on cognitive function, physical function, and daily function/participation and psychological function in persons with cognitive impairments post Traumatic brain injury (TBI); (2) determine the long-term effects of these two types of interventions on these outcome measures.
This is a pilot study with the aim of evaluating the feasibility of the procedures of a future clinical trial that will help determine the impacts of hearing aid interventions on older patients with Alzheimer's Disease and related dementias (ADRD). In this pilot study individuals with mild or moderate cognitive impairment, as well as their caregivers, will be recruited. Participants will be randomly assigned to three intervention groups: Audiologist-Based Intervention, Service-Only Group, and Device-Only Group. Outcome data will be collected on the how hearing loss and hearing aid impact their lives and caregiver burden 6-week post hearing aid intervention.
The aim of this study is the efficacy of a docosahexaenoic acid (DHA)-rich dietary supplement in improving key dementia-related mechanisms and cognitive function in older people at risk for dementia. This is a randomized placebo-controlled, 24 weeks, phase 2 study of Omega 3 in people with increased risk of dementia. The aim is to explore the effects of DHA on cognitive performance (CERAD 10 word memory tests, TMT A/B, Stroop Color-Word, FAS, VOSP silhouettes, Cantab-test (RT, PAL, SWT)), biological markers (blood: CRP, NLF, TNF-alpha, MCI-1, PBMC Abeta middomain, Omega-3-index, IL, CSF: NLF, sTREM2, Ab 1-42, total and -phospho-tau) and imaging (MRI: standard structural DDI protocol including Freesurfer and WML measurements, DTI and ASL).
Due to the demographical development, age-related diseases will drastically increase over the next decades. To face this healthcare challenge, early and accurate identification of cognitive impairment is crucial. The assessment of neurocognitive functioning ideally requires a tool that is short, easy to administer and interpret, and has high diagnostic accuracy. In this context, the use of computerized test batteries is receiving increasing attention. Compared to paper-pencil tests, computerized test batteries have many advantages. The possibility to measure reaction times may provide additional information. Moreover, test questions are always presented the exact same way, examiner-related bias is eliminated, and results are available immediately after examination. Due to the ability to adjust the level of difficulty to the performance of the individual, floor and ceiling effects may be minimized. Additionally, costs are reduced, and fewer materials and less trained personnel are required. Finally, big data approaches and the use of machine learning algorithms are becoming more popular in the field of clinical diagnostics, and computerized cognitive test batteries may facilitate future data collection to this aim. In 2014, we developed a self-administered tablet computer program for the iPad (CogCheck) to assess preoperative cognitive functioning in surgery patients. The cognitive tests used in the CogCheck application are identical or similar to the paper-and-pencil tests that are currently used in dementia diagnostics. Replacing some of the paper-and-pencil tests by a computerized test battery may facilitate the routine neuropsychological examinations. Thus, we aim to investigate the diagnostic accuracy and user-friendliness of CogCheck when applied in a cognitively impaired patient sample. In a first step, the diagnostic properties of CogCheck will be examined by differentiating between healthy controls and patients with mild or major neurocognitive disorder (NCD) predominantly due to Alzheimer's disease (AD). Data from healthy controls have been collected (EKNZ Req-2016-00393) in a previous normative study of CogCheck. Thus a further aim is to investigate the user-friendliness of CogCheck in patients with mild or major NCD predominantly due to AD. The primary aim of our study is to investigate the diagnostic accuracy of CogCheck for patients with mild or major NCD predominantly due to AD in a German-speaking population. Secondary aims are: (1) to examine the user-friendliness of CogCheck in patients with mild or major NCD predominantly due to AD, (2) to compare the results between cognitively healthy individuals (EKNZ Req-2016-00393) and patients with mild or major NCD predominantly due to AD on each of the CogCheck subtest, (3) to establish an algorithm with the CogCheck subtests that optimally distinguishes between cognitively healthy controls (EKNZ Req-2016-00393) and patients with mild or major NCD predominantly due to AD, (4) to compare the diagnostic properties of CogCheck with the ones of the currently used paper-pencil tests.
Electrical activity in the brain known as "gamma" brainwaves help connect and process information throughout the brain. These gamma waves are diminished in Alzheimer's disease. New research in Alzheimer's disease mouse models shows that exposure to light flickering at the rate of 40 flashes per second or 40Hz increased gamma brainwaves and led to clearing of beta amyloid plaques in the brain, a key abnormality in Alzheimer's disease. This project will test the ability of a novel iPad App (AlzLife https://www.alz.life/) that delivers light therapy at 40 Hz combined with cognitive therapy to improve cognition, function, and quality of life in Alzheimer's disease.
We aim to make clear the impact with the mechanisms of variant pathological injuries on the outcomes of CSVD, to find independent imaging markers and establish prediction model of it.
This observational cohort study is designed to validate the CogCheck application as a risk prediction tool for postoperative delirium in patients undergoing cardiac surgery.
Background: The transition to long-term care facility can be a stressful and emotional event for the elderly. The evidences showed that the prevalence of depression and the cognition impairment were higher in the institutionalized elderly than the community dwelling elderly. It could affect the quality of life of the elderly and increase risk of mortality. Purpose: The aim of the study is to evaluate the effect of outdoor activities and sunlight exposure on depression, cognitive function, and quality of life among institutionalized elderly. Method: The design is a randomized control trial. Participants will be randomly allocated to experimental or control groups by block randomization. In the experimental group, participants will be encouraged to reduce time spent on bed and bedroom. Nurses, nurse aids or family will take participants outdoors and exposure their face, hands or arm to sunlight for 15-30 minutes a day, five days a week for three months (if the UV index is over 8 according to the forecast of Center Weather Bureau, the participants will be asked to stay inside). In the control group, the participants will receive routine care. The control group will neither be encouraged to stay outdoors nor limit the chance to exposure to sunlight. Expected outcome: The expected benefit of the research is to improve the depression, cognitive function, and quality of life of the institutionalized elderly.
The HKU Neurocognitive Disorder (NCD) Cohort is a hospital-based, prospective, observational study of older HK Chinese adults with cognitive impairment, with a special focus on studying patients with subjective cognitive decline and mild cognitive impairment.
Postoperative cognitive impairment is one of the most common complications in elderly surgical patients. Laser laryngeal surgery is a short procedure, but characterized by high risk of disastrous airway fire. So the recommended oxygen concentration is less than 30%. For elderly patients, because of preoperatively declined cardiovascular and lung function and cognitive function, there is a potential that intraoperative low oxygen concentration may lead to drop of arterial oxygen tension, decrease of brain oxygenation, and exacerbate brain function impairment. Intravenous anesthesia and inhalation anesthesia is two commonly used technique for general anesthesia. Consequently, we carry out this study to identify whether different classes of anesthetics can affect postoperative cognitive function in old patient undergoing laser laryngeal surgery.
