Cerebral small vessel disease is a frequent cause of cognitive disability among older adults (OAs) in Mexico that imposes a significant burden on the health system and OAs' families. We have called the program Mind and Movement for Cognitive Health (MeMo-Salud-Cog-3). Programs to prevent or delay OAs' cognitive decline are scarce. Methods and analysis: A double-blind, randomized clinical trial will be conducted. The study will aim to evaluate two 24-week double-task (aerobic and cognitive) square-stepping exercise programs for OAs at risk of cognitive decline-one program with and another without caregiver participation-and to compare these with an aerobic-balance-stretching exercise program (control group). 255 OAs (85 per group) affiliated with the Mexican Institute of Social Security (IMSS) between 60 and 65 years of age with self-reported cognitive concerns will participate. They will be stratified by education level and randomly allocated to the groups. The intervention will last 24 weeks, and the effect of each program will be evaluated 12, 24, and 52 weeks after the intervention. Participants' demographic and clinical characteristics will be collected at baseline. The outcomes will include: (i) general cognitive function; (ii) specific cognitive functions; (iii) dual-task gait; (iv) blood pressure; (v) carotid intima-media thickness; (vi) carotid arterial compliance; (vii) OAs' health-related quality of life; and (viii) caregiver burden. We will estimate differences in outcomes between each intervention group and the control group at baseline and follow-up evaluations. We will assess differences-in-differences (D-in-D) treatment effects using a D-in-D estimator. If we identify statistically significant differences in participants' baseline characteristics between the groups, we will adjust the D-in-D estimators by these covariates using generalized linear regression models. Ethics and dissemination: The study was approved by the IMSS Ethics and Research Committee (registration number 2018-785-095). All participants will sign a consent form prior to their participation. The study results will be disseminated to IMSS authorities, healthcare providers and the research community.
This study evaluates a novel arm restraint compared with traditional soft wrist restraints in older critically ill patients. The primary outcome is upper extremity mobility measured by actigraphy, and secondary outcomes include sedation, agitation, satisfaction, and acceptability.
A clinical trial to test the clinical and cost-effectiveness of a therapy intervention designed to promote activity and independence and reduce falls, amongst people with early dementia or mild cognitive impairment
Evaluate cognitive improvement pre amd post acupuncture treatment in patients with probable alzheimer's dementia as measured by MOCA score and also per form A( measure of patient's personal information). Also caregiver input.
This study evaluates the efficacy and mechanism of internet-based cognitive training in patients with amnestic mild cognitive impairment (aMCI). Half of participants will receive multi-domain adaptive internet-based training program, while the other half will receive a fixed, primary difficulty level task.
Thus far no large randomized trial has demonstrated a correlation between screening and improved outcomes. This would need to be done to gain widespread acceptance of screening and case finding programs. Early detection of cognitive impairment could potentially result in the appropriate treatment of reversible cognitive impairment conditions or earlier initiation of pharmacological interventions for the management of a variety of other dementia or Mild Cognitive Impairment (MCI) conditions. A screening approach that reduces the number of false positive screens would improve the comfort level of physicians and patients with cognitive screening programs. The investigators propose to use the Self-Administered Gerocognitive Examination (SAGE) and the Electronic Self-Administered Gerocognitive Examination (eSAGE) to identify patients who score in the cognitive impairment range during an office visit with their primary care provider. Conversation with an individual who knows the patient well (if possible) will be performed to ascertain a significant change in the patient's cognitive skills over the previous year. The investigators wish to determine if screening for cognitive impairment in this way leads to new diagnoses and management outcomes compared to a group of primary care providers who use their current usual method in screening for cognitive impairment during office visits.
it is a prospective longitudinal observational study, aiming to to identify clinical, and biochemical baseline predictors of motor and non-motor PD progression in sample of Egyptian patients. it measures the baseline motor, non-motor, biochemical and imaging characteristics at enrollment and its relation to PD progression over 3 years
In Hong Kong, methamphetamine use is common and cocaine use has increased steadily over the past few years. While the use of ketamine decreased from 35.8% in 2015 to 13.9% in 2017, methamphetamine and cocaine have become the most commonly used psychotropic substances and account for more than 50% of drug abuses cases in 2017. Among all stimulants, methamphetamine is most commonly used because it releases three times more dopamine than cocaine and the effects can last from eight to twelve hours, compared to two hours for cocaine. On top of its extreme effects, methamphetamine is relatively inexpensive, making it even more accessible to the young population. Misuse of methamphetamine has long been associated with profound psychological and cognitive disturbance. In reviewing the cognitive data from reasonably well-matched groups of chronic methamphetamine users and healthy controls, the majority of studies have found that chronic methamphetamine users had lower scores on at least some cognitive tests, although some studies are exceptions with entirely nonsignificant differences. A meta-analysis of 17 cross-sectional studies found that chronic methamphetamine users demonstrated significantly lower cognitive scores than healthy controls. The effects were largest for measures of learning, executive functions, memory, and processing speed, although the majority of cognitive domains significantly differed between the groups. Concerns has been emerging regarding the methodology of the aforementioned results. In particular, the appropriateness of using healthy controls to examine the cognitive effects of stimulant use has been questioned. Much of the published research has fallen victim to using controls with significant baseline differences from the chronic stimulant users, such as years of education. In addition, none of the studies available provided scatter plots of their cognitive data to evaluate the overlap in performance between chronic stimulant users and healthy controls. In fact, many chronic stimulant users have normal cognitive function when compared with normative data. Therefore, the use of the term 'impairment' or 'deficit' in many studies is not fully justified. Another limitation is that it cannot differentiate cognitive weaknesses that may predate stimulant use from those that result from it. Notably, longitudinal studies have shown that childhood deficits in executive function can predict drug abuse in adolescence, suggesting that at least some of the cognitive weaknesses pre-exist in chronic stimulant user. These and other limitations provoked a conclusion that the evidence for cognitive deficits in chronic stimulant users is weak. In order to overcome the methodological issues observed in previous cross-sectional studies, we propose to conduct a prospective studies to determine the change in cognitive function among stimulant users over time.
Mild cognitive impairment (MCI) is an intermediate stage between the expected cognitive decline of normal aging and severe dementia associated with Alzheimer's disease (AD). In the United States about 20% of older adults have MCI. Loss of cognitive function in aging can have far-reaching and devastating impacts on functional status, independence, and quality of life. Unfortunately, the therapeutic options to slow progression of cognitive decline in aging are limited. Dual-task training; that which involves simultaneous cognitive and motor challenges, is a high-impact potential therapy to slow progressive loss of both motor and cognitive function in aging. The purpose of this trial is to examine the feasibility and therapeutic impact of a novel dual-task physical activity intervention on executive and motor functions among adults, 65 years or older, who have MCI. the investigative team anticipates that findings from this trial will inform development of larger community-based studies focused on improving function and ability to maintain independence in older age.
