Filter by:The goal of this observational study is to explore the optimal dose of computerized cognitive training in patients with cognitive impairment. The main questions it aims to answer are: - Is there an optimal dose of computerized cognitive training for patients with cognitive impairment? - Is the optimal dose different in patients in different age populations? Participants enrolled in the study took a reported computerized cognitive training program and the training data were analyzed for exploring the optimal dose. The researchers will compare the different dose groups to see if there is an optimal dose for the highest improvement in cognitive abilities. The researchers will additionally compare two age groups (aged younger than 60y or aged 60y and older) to see if the optimal doses in the two groups are different.
The goal of this clinical trial is to [learn about cognitive stimulation by multidomain dietary education including the dietary board game via LINE in non-dementic type 2 diabetic adults. The main questions it aims to answer are: [Question 1: Could multi-domain dietary education as cognitive stimulation improve cognitive function?] [Question 2: Could multi-domain dietary education improve dietary control belief ?] [Question 3: Could multi-domain dietary education improve health behavior?] [Question 4]: Could multi-domain dietary education improve HbA1C, and lipid profile? Participants of experimental A group will receive a video about lifestyle education 5 minutes weekly for 3 weeks, a dietary board game 10 minutes weekly for 10 weeks, and a 24-hour dietary recall record 2 times weekly for 7 weeks. And participants of the experimental B group receive the usual clinical treatment. Then experimental A and Experimental B groups will cross over 12 weeks later. Researchers will compare the effect of intervention between the experimental A group and the experimental B group.
This study investigated the efficacy of the Silvia program, a mobile-based multidomain intervention, to improve cognitive function and health-related outcomes of older adults with a high risk of dementia. We compare its effects to a conventional paper-based multidomain program on various health indicators related to risk factors of dementia.
Background: Sleep disturbances are highly prevalent in ageing population and patients with age-related neurodegenerative diseases, which severely affect cognition and even lead to accumulated amyloid-β (Aβ). At present, non-pharmacological interventions for sleep disturbances in dementia patients are accepted as first line of treatment, of which the evidence from clinical trials is very limited. Encouraging results from recent studies on transcranial direct current stimulation (tDCS) showed moderate positive effects on sleep quality in preclinical Alzheimer's disease (AD). Compared to tDCS, high-definition transcranial alternating current stimulation (HD-tACS) enables the entrainment of neuronal activities with optimized focality through injecting small electric current with a specific frequency and has significant enhancement effects on slow wave activities. Objectives: The investigators aim to 1) investigate and compare the safety, efficacy and sustainability of 40 Hz HD-tACS and HD-tDCS over left dorsolateral prefrontal cortex (DLPFC) in mild neurocognitive disorder due to AD (NCD-AD) patients with sleep disturbances; 2) examine the relationship between the changes in sleep quality, cognitive function and saliva Aβ levels. Methods: Chinese right-handed mild NCD-AD patients with sleep disturbances (aged from 60 to 90 years) will be randomly assigned to a 4-week intervention of either HD-tACS, HD-tDCS, or sham HD-tCS, with 33 participants per arm. Before intervention, structural magnetic resonance imaging (MRI) data is used to construct individual realistic head model. Comprehensive assessments, including sleep quality, cognitive performance and saliva Aβ levels will be conducted at baseline, 4th week, 8th week, 12th week and 24th week. Program adherence and adverse effects will be monitored throughout intervention. Data analysis: The primary outcomes will be the changes in sleep quality and memory performance with modality-driven paradigms (HD-tACS, HD-tDCS, sham HD-tCS), and comparisons of group differences across different time points. Secondary outcomes will be the changes objective sleep pattern, global cognition, saliva Aβ levels and quality of life. Intention-to-treat analysis will be carried out. Changes of efficacy indicators from baseline to each follow up point will be tested with mixed effect model. Significance: This study aims to investigate the feasibility, safety and efficacy of HD-tACS and HD-tDCS over left DLPFC for sleep disturbances and cognitive dysfunction in mild NCD-AD patients. It wills also test the program adherence, tolerability and adverse effects of this innovative neurotechonology. Information will be helpful for in-depth understanding the relationship of "sleep disturbances-amyloid deposition" and guiding the further studies of sleep medicine and neurodegenerative diseases.
High risk infant is defined as infant with a negative history of environmental and biological factors, which can lead to neuromotor development problems. It is a heterogeneous group of premature infants born under thirty-seven weeks of age, with infants with low birth weight, term or developmental retardation for various reasons. Therefore, preterm infants with low birth weight can survive with a neurological sequelae such as cerebral palsy (CP), epilepsy, hearing and vision loss, mental retardation, speech and speech problems, and learning difficulties. The clinical diagnosis of CP and learning diffuculties which can be observed in high-risk infants, is based on the combination of some neurological and clinical signs.
The intervention program proof-of-concept was assessed as a single-arm, within-subjects clinical study with a target enrollment of 10 participants with possible or probable amnestic MCI. The protocol required participants to complete a pre-intervention assessment within two weeks of beginning the intervention, attend seven, one-hour intervention group sessions across six weeks, complete a post-assessment and interview in the final week of the intervention, and complete weekly surveys throughout the intervention.
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.
Background: Many studies suggest physical activity reduces risk of dementia and improves global cognitive function in individuals with mild cognitive impairment (MCI). Using commercial wearable technology to measure daily steps is feasible in this population. Objectives: The purpose of this pilot study was to explore whether 12 weeks of increased physical activity improved cognitive function in individuals with MCI. A wearable activity tracker was used to measure participants' daily steps as a quantifiable measure of daily activity level. Design: This was a one-group pretest-posttest study. Setting: Established memory clinic patients within a neurology department in Northern California during 2019. Participants: 17 enrolled and 14 included for data analysis. There were 7 females and 7 males whose mean age was 76.21 (SD 2.69). 12 participants were White, which reflected the clinic population. Intervention: Participants were asked to wear an activity tracker for approximately 12 hours a day for 12 weeks and to increase their physical activity as much as possible. They were provided twice a month telephone support. Measurements: The Montreal Cognitive Assessment (MoCA) was used to measure pretest-posttest cognitive function. Timed Up and Go (TUG) was used to assess fall risk at enrollment. Cumulative step count for the study period was measured with an activity tracker.
Alzheimer's is a type of dementia that affects memory, thinking and behavior. Symptoms eventually grow severe enough to interfere with daily tasks. this study aimed to delay the deterioration of anemic elderly condition as memory affection interfere with daily life activities and social interaction
The multi-domain programme was adapted from a larger international multi-domain interventional study for the Singapore community of older adults at risk of cognitive impairment. This programme comprises nutritional, physical and cognitive components delivered by implementation partners in the community. A dementia risk screening tool developed from the Singapore Longitudinal Ageing Study (SLAS) data was used to screen potential participants. The nutritional component includes nutrition guidance via a nutritional app, while cognition component involves computerised training on a touch screen device and physical aspects involves dual-task exercises.
