Filter by:With the aging of the population, an increase in neurocognitive diseases such as dementia is projected. Mild cognitive impairment is considered a precursor stage to dementia, with opportunities for intervention to prevent its progression. Additionally, these illnesses can harm the primary caregiver, who is often an unskilled family member. This is a randomized clinical trial in patients with mild cognitive impairment and their main caregivers. The intervention will be tested in the dyad for 12 weeks, twice a week with professional support and once a week with caregiver support, the latter will be intervened once a week for 12 weeks. The primary outcome will be the change in cognitive function and its domains. Secondary outcomes will evaluate favorable changes in quality of life in the patient-caregiver couple, frailty, physical capacity, independence, nutritional status, social support, and family caregiver burden. These measurements will be taken at baseline, 3, 6, and 9 months of follow-up. Furthermore, in a subsample of the study population, the taxonomic and metabolomic composition of the intestinal microbiota and the presence of the E4 allele of the APOE (apolipoprotein E) gene will be evaluated before and after the intervention.
Hip fractures are more common in older people due to osteoporosis. It is estimated that around six million patients worldwide will suffer hip fractures annually by 2050 as the population ages [1]. Clinically, hip surgery is a common and effective treatment for hip fractures. There will be an increasing number of older people undergoing hip surgery, including osteosynthesis and arthroplasty. However, severe surgical trauma, postoperative pain, and postoperative cognitive dysfunction (POCD) can be a considerable challenge for older people undergoing hip surgery [2, 3].The successful use of QLB with all approaches has been reported in case reports for the following surgical procedures: proctosigmoidectomy, hip surgery, above-knee amputation, abdominal hernia repair, breast reconstruction, colostomy, closure, radical nephrectomy, lower extremity vascular surgery, total hip arthroplasty, laparotomy, and colectomy. Ultrasound-guided quadratus lumborum block (QLB) is a recently described fascial plane block in which the anesthetic is injected adjacently to the quadratus lumborum (QL) muscle with the goal of anesthetizing the nerves in the thoracolumbar region [17,18]. As a trunk nerve block, quadratus lumborum block (QLB) has been widely used for postoperative analgesia in patients undergoing abdominal and lower limb surgeries [19]. QLB can provide adequate analgesia and reduce opioid requirements after hip surgery [20]FICB or fascia iliaca block (FIB), first proposed in 1989, is a means ofblocking the three principal lumbar plexus nerves of the thigh with a single injection of local anesthetic delivered immediately dorsal to the fascia iliaca [21,22]. Indications of FICB are surgical anesthesia to the lower extremity, management of cancer pain and pain owing to inflammatory conditions of the lumbar plexus, and amelioration of acute pain following trauma, fracture, and burn [23]. Fascia Iliaca Block (FIB), which is widely used for postoperative analgesia in hip surgery, is a nerve block technique with proven efficacy[24].
The goal of this randomized controlled trial is to learn if Transcranial Pulse Stimulation (TPS) can improve cognitive functions in older adults with mild cognitive impairment (MCI). The study will also assess the safety of TPS. The main questions it aims to answer is: Does TPS improve cognitive functions such as global cognition, attention, memory, and executive function? Researchers will compare TPS to a sham control to evaluate the efficacy and safety of TPS in improving cognitive functions in older adults with MCI. Participants will: Be randomly assigned to receive either TPS or a sham intervention Undergo 6 sessions of TPS or sham intervention over a 2-week period Visit the clinic for cognitive assessments at 4 different time points (baseline, immediately post-intervention, 1-month follow-up, and 3-month follow-up) Complete questionnaires and undergo standardized neurocognitive tests, and/or MRI scans, and/or EEG assessments The study aims to provide insights into the potential therapeutic role of TPS in enhancing cognitive functions among older adults with mild cognitive impairment.
The purpose of this study is to test the Green Activity Program that was designed with Hispanic/Latino people living with memory challenges and their study partners to see if it can be done and if they enjoy the program. "Green activities" are nature activities that the person enjoys and can be done with other people or pets. For example, dog walking, hiking, outdoor yoga, and gardening are all green activities. The purpose of the program is to help people living with memory challenges participate in nature activities they enjoy. The goal of the program is to help people stay active and improve their health and well-being.
The National Institute on Aging together with the Alzheimer's Association (NIA-AA) recently proposed the ATN classification which is based upon the pathological processes present in Alzheimer's disease (amyloid, tau and neurodegeneration). The amyloid and tau status can be defined using cerebrospinal fluid analysis but also non-invasively using an amyloid or tau PET scan. The N status can be defined using an [18F]-FDG PET scan which is in Belgium part of standard of care. Recently, it has been demonstrated, using different amyloid PET tracers, that early-frame amyloid scans can be a surrogate for [18F]-FDG PET scan.
A 12-weeks Intensive Aerobic and Resistance Exercise Program (IAREP) intervention will be implemented on high-risk and low-risk of cognitive impairment subjects in type 2 Diabetes Mellitus. The study aim to evaluate the effectiveness of IAREP on cognition, metabolic health, physical health, and psychological health in Type 2 Diabetes Mellitus population.
This is a proof of concept observational study is to determine if there is correlation between Aβ plaques and vascular findings in the Retina versus brain ARIA.
The goal of this study is to assess the feasibility and effect of digital cognitive training based on the principles of Differential Outcome Training (DOT) in patients with Mild Cognitive Impairment. In DOT training, each stimulus-response pair to be learnt is followed by a unique reinforcer, as opposed to non-DOT (NDOT) training, where the stimulus-response pairs are all followed by a random reinforcer. DOT training is believed to boost learning more than NDOT training through associations. The main questions the study aims to answer are: - Whether at-home, tablet-based digital cognitive training is feasible in elderly patients with Mild Cognitive Impairment - Whether regularly digital cognitive DOT training has a positive effect on patients' cognitive functioning and quality of life - Whether any potential effects that the cognitive DOT training may have on the patients' cognitive functioning are transferable to the patients' daily life. Participation in the study includes: - A pre-training session at the site with the primary project coordinator, where the patient will complete a number of self-report questionnaires about their health, cognition, and quality of life as well as a neuropsychological assessment. - Training with the digital cognitive DOT training program at home for 20 min. per day 3-4 times a week for 6-8 weeks. - A post-training session at the site with the primary project coordinator after the 6-8 weeks have passed, where the patient will complete a usability questionnaire about the training programme, some of the same self-report questionnaires about their health, cognition, and quality of life as well as some of the neuropsychological assessments. - A 1-month follow-up session where the patients will complete some of the same self-report questionnaires again about their cognition and quality of life plus a questionnaire aimed the transferability of any positive cognitive effects of the training.
This cross-over pilot study aims to study the acceptability of two methods of non-invasive brain stimulation for the treatment of Parkinson's disease mild cognitive impairment (PD-MCI) - repetitive transcranial magnetic stimulation (rTMS) and transcranial direct current stimulation (tDCS) targeted at the left dorsolateral prefrontal cortex (DLPFC). Twenty participants will undergo both interventions in a cross-over design. They sequentially undergo four consecutive phases (4 weeks each), 1) no-intervention baseline, 2) rTMS ór tDCS, 3) no-intervention, 4) second intervention. The primary outcome measure will be acceptability of the interventions, and secondary outcomes include feasibility, cognitive function, neuropsychiatric symptoms, motor function. We will use MRI to explore personalized targeting.
The goals of the proposed research are to first determine the minimal and/or optimal dose of a digital intervention required for cognitive enhancement, and then to examine the impact of several potential moderators of treatment effects (i.e., cognitive decline, AD polygenic hazard score, cardiovascular risk, and race/ethnicity). This knowledge gained from his high-impact study with transform the field of cognitive interventions, paving the way for a precision medicine model for cognitive enhancing interventions that improve quality of life for older adults and individuals with cognitive deficits at risk of developing dementia.
