Filter by:Older adults with Mild Cognitive Impairment (MCI) have an increased risk of developing dementia but do not meet the criteria for dementia. Cognitive rehabilitation makes it possible to compensate, at least in part, for cognitive deficits with the ultimate goal of reducing their impact in everyday life. The objective of the research is to evaluate the short- and long-term effectiveness and generalization of an attention and working memory training program (APT-II) on cognition and ecological activities in MCI patients with a randomized controlled trial. Thirty MCI patients will be randomly assigned between a "cognitive training with APT-II" condition and a control (routine care) condition. The intervention will consist of an 8-week individual cognitive training program (2 sessions/week), training different attentional components and working memory. This has the advantage of insisting on the transfer of the acquired knowledge in sessions to daily activities. To evaluate the effectiveness of the treatment, cognitive and functional follow-up measures (including a virtual reality task) are administered at several time intervals. This project should contribute to better management of cognitive disorders by offering a new standardized rehabilitation tool in French to clinical practice.
Postoperative cognitive dysfunction (POCD) is one of the common complications of cancer patients after operation with a 8.9%-46.1% incidence, which severely affecting patients' postoperative recovery, increasing the medical cost, affecting the social function of patients, reducing the quality of life and increasing the mortality. Surgical trauma and perioperative pain can induce systematic inflammatory response and release systematic inflammatory mediators, which can enter the central nervous system (CNS) and lead to CNS inflammatory. In order to prevent the development of POCD among elder patients, the discovery of effective interventions reducing perioperative pain and inflammatory response is important. Transcutaneous Electrical Acupoint Stimulation (TEAS) is a non-invasive alternative to needle-based electro-acupuncture (EA). It combines the acupuncture and transcutaneous electrical nerve stimulation (TENS) by pasting the electrode piece on the acupoint instead of sticking the needles on the skin. TEAS can trigger the release of endogenous neurotransmitters, releasing endogenous analgesic substances, such as endorphins. TEAS also can reduce the intraoperative anesthetic consumption, postoperative pain score, postoperative nausea and vomiting (PONV), and improve the postoperative recovery of patients. Recently, TEAS was found to improve the cognitive function of geriatric patients with silent lacunar infarction. However, the current TEAS mainly focus on intraoperative. The effect of perioperative TEAS on POCD is not clear. Here, the effect of TEAS on POCD in geriatric adults undergoing radical resection of gastrointestinal tumors under general anesthesia was investigated to determine whether TEAS can decrease perioperative pain or inflammatory response to prevent the occurrence of POCD and to find out the relationship among perioperative TEAS, inflammatory response, postoperative pain, and POCD preliminarily.
The primary purpose of this study is to evaluate the safety and tolerability of SAGE-718 and its effects on cognitive and neuropsychiatric symptoms in participants with mild cognitive impairment (MCI) or mild dementia due to Alzheimer's disease (AD).
The hospitalized elderly patient is conditioned by a series of circumstances unrelated to the pathological process itself that caused hospital admission and that usually worsen the results of hospitalization. In fact, the implementation of care models different from the traditional ones has shown a clear benefit in the functional results of these patients in the short and medium term. However, the components of these models that explain these better results have not been differentially evaluated. Some examples of these circumstances are the usual orders of absolute rest without any objective criteria for patients who are able to wander, the perpetuation of continuous fluid therapy, physical and chemical restraints, unnecessary permanent probes, etc. On numerous occasions, hospitalized elderly patients spend most of their time in bed, reaching even more than 83% of bedridden compared to 4% of those who stand up or are walking. The average time that a geriatric patient walks during their hospitalization ranges from 7 to 43 minutes/day. This population, by having their functional and physiological reserve reduced, are more vulnerable to the effects, for example, of bedridden, which range from functional loss or cognitive impairment, to longer stays, mortality and institutionalization, worse emotional situation, delirium, deconditioning, aspirations, pressure ulcers, and falls, decreased caloric intake, social isolation, poorer quality of life, and greater use of health-related resources. This study is a multicenter randomized clinical trial to be conducted in the acute care for elderly (ACE) units of three tertiary hospitals in Spain - Complejo Hospitalario de Navarra (CHN), Hospital Central de la Cruz Roja de Madrid (HCCRM) and Complejo Hospitalario Universitario of Albacete (CHUA). After randomization, the research team (physiotherapist, sport science specialist and geriatrician) will together perform the baseline measurement and follow-up visits of functional, pharmacological, comorbidity and cognitive assessment, as well as of mobility and strength evaluations. The intervention will consist of a multicomponent exercise training programme, which will be composed of supervised progressive resistance exercise training, balance-training and walking for 4 consecutive days. During the training period, patients will be trained in 20 min sessions twice a day (morning and evening).
This is a pilot, randomized, double-blinded, placebo-controlled, 12-month trial of 50 patients with CKD stage 3b-4 with metabolic acidosis to examine the effect of sodium bicarbonate therapy on cognitive and cerebrovascular function.
Many perioperative factors have been pointed out as the risk factors for postoperative cognitive dysfunction, which may occur immediately after the surgery, days after the surgery, or months after the surgery. Quick mild cognitive impairment screen (Qmci) is a sensitive and specific test to differentiate mild postoperative cognitive dysfunction. However, the learning effect have been raised as a bias when we repeated the same test for one person at different timing. Thus the study is designed to collected the Normative Data in series for the Qmci-TW in a Taiwanese Sample.
This study aims to investigate the association between listening effort and cognitive function for both cognitively healthy individuals and for patients with Mild Cognitive Impairment (MCI) in mid-to-late stages of life, and furthermore to investigate listening effort and cognitive function after several weeks of hearing aid use. Listening effort is measured by the recording of peak pupil dilation during a sentence-final word identification and recall (SWIR) test, cognitive performance is measured using a battery of pen and paper cognitive tests, and hearing loss is measured with pure tone audiometry (PTA). A select number of participants in both the cognitively healthy and MCI group will be administered hearing aids, and the study will re-test both listening effort and cognitive performance.
Acute Respiratory Distress syndrome (ARDS) is a pulmonary systematic inflammatory response, leading to acute respiratory failure with hypoxia and/or hypercarbia. COVID-19 evokes a viral pneumonia, which may result in ARDS as well. It is not yet clear if COVID-19 disease behaves like the typical ARDS. Corona virus causes primarily deep hypoxia. Hypoxia, on its own, can lead to long term cognitive impairment. However, critical illness also affects long-term neurocognitive functioning. The investigators will be researching the possibility of long-term cognitive impairment in COVID-19 ICU patients, in comparison with reference values of a healthy population as well as the values measured in critically ill patients, admitted not only for respiratory reasons.
A randomized, parallel-group, double-blind, exploratory two-arm trial to assess the effects of CBD on driving ability along with changes in psychological status (i.e. mood, drowsiness, sedation) and cognitive function. Forty healthy West Virginia University (WVU) students will be allocated and randomized to receive: (1) 300 mg of pure CBD oil or (N=20) (2) placebo matched in appearance and taste (N=20). After consuming the study drug, each individual will participate in a 25-35-minute driving simulation and their driving performance measured. To assess changes in psychological status (i.e. mood, drowsiness, sedation) and drug impairment-related cognitive function, the Visual Analog Mood Scale, Stanford Sleepiness Scale , Digital Symbol Substitution Test, Trail Making Test Part A and B, Psychomotor Vigilance Test, and Simple Reaction Time test will also be administered to participants at baseline (prior to study drug consumption) and following completion of the driving simulation test. The entire protocol will be completed in one day and should take 4-4.5 hours to complete for each participant.
Background: A dearth of differential research exists regarding the determinants of mild cognitive impairment (MCI) and moderate cognitive impairment or dementia among nursing home residents. This study aimed to identify and examine the association between medical factors (number of comorbidities, hospitalization, disability, depression, frailty and quality of life) and moderate cognitive impairment or dementia in nursing homes residents. Methods: A cross-sectional design was used in this study. Convenience sampling of 182 participants was conducted in nursing homes located in the central part of Jordan. Montreal cognitive assessment (MoCA) was used to screen both MCI and moderate cognitive impairment or dementia. Bivariate analysis, including t-test and ANOVA test, and logistic and linear regression models were used to examine and identify the medical factors associated with moderate cognitive impairment or dementia compared to mild cognitive impairment.
