Filter by:Post-stroke cognitive impairment(PSCI) refers to a clinical syndrome characterized by cognitive impairment that occurs after a stroke event and persists for 6 months. PSCI is divided into post-stroke cognitive impairment non-dementia and post-stroke dementia. About one half of patients develop PSCI within the first year after stroke. Recent large international cohort studies have reported that the incidence of PSCI is 24%-53.4%, among which the incidence of cognitive impairment after stroke without dementia is 14%-29% and the incidence of dementia after stroke is 11%-42%. A study in China shows that the incidence of PSCI is 53.1%. Our previous small sample study also found that the incidence of cognitive impairment in acute phase of ischemic stroke patients was 64.52%. It can be seen that the incidence of PSCI is high, which is an important health problem. The mortality rate of stroke patients complicated with PSCI is significantly higher than that of patients without cognitive impairment. The 5-year survival rate of patients with post-stroke dementia is only 39%, while the survival rate of stroke patients without dementia of the same age is 75%. In addition, patients with PSCI will lead to long-term disability, a significant decline in self-care ability of daily living, quality of life and mental health status, poor social participation ability, and increased care pressure. If not intervened in time, will bring serious disease and economic burden to the family and society. Therefore, preventing the occurrence and delaying the progression of PSCI is an important task to be solved urgently. Rehabilitation is an important intervention to delay the progression of PSCI, aiming to promote the remodeling of the central nervous system, and the main method is early and multi-dimensional cognitive function training. Some studies have confirmed that computerization, multi-cognitive domains, and adaptive cognitive training (7 consecutive weeks, 5 days a week, 30 min a day) can significantly improve the global cognitive function of patients with cognitive impairment after subcortical stroke and non-dementia . A recent systematic review showed that cognitive training can improve the cognitive function and daily living ability of patients with mild PSCI. It also has a certain effect on the improvement of patients' overall cognitive function. It can be seen that cognitive training is not effective for all stages of PSCI patients, and the effect of cognitive training is very limited for patients who have developed into a single dimension of severe damage, serious overall cognitive impairment even dementia. This suggests that targeted cognitive intervention for patients at the acute stage of stroke may achieve the purpose of preventing the occurrence and delaying the progression of PSCI. Therefore, this study innovatively proposed the concept of preventive cognitive training for patients with acute stroke. In the basis of literature research, combined with the views of the cognitive domain experts and Kang Fushi reformed the existing cognitive training plan, build the computer-assisted ladder multidimensional cognitive training scheme, the main dimensions set up on the basis of cognitive training program, according to the degree of cognitive impairment at the same time set the difficulty level of the project, It is convenient for medical staff to select appropriate items and difficulties based on the dimension and degree of cognitive impairment of patients. To evaluate the effect of cognitive training by using cognitive function scale, psycho-psychological scale, self-care ability scale and other tools, and to clarify whether acute preventive cognitive training can improve PSCI, so as to provide a practical basis for the prevention and intervention of PSCI.
This is a study on patient registry, and the sample size of this clinicaltrial is designed in group sequential design. According to the diagnostic criteria, the subjects are divided into SCD group, MCI group and mild dementia group. At the early stage of treatment, the investigators give participants transcutaneous electrical acupoint stimulation and music therapy according to the guidance of TCM syndrome differentiation. Participants can treat themselves at home after the investigators give them intelligent device and music，and according to the TCM syndrome score, neuropsychological scale, curative effect evaluation of daily life ability scale, determining the optimal comprehensive treatment plan,and phase in the treatment of participants with food, clothing, shelter, line, and life aspects of health education and guidance, a total of 24 weeks of treatment.
Nordic walking in water would more advantage than normal daily life in cerebrovascular function and cognitive function in elderly with type 2 diabetes.
The main aim of the study is to characterize and understand the pathological mechanisms underlying the motoric cognitive risk syndrome, which is a predictor of Alzheimer disease.
This is a randomized, double-blind, sham-controlled, adaptive-design pivotal study of sensory stimulation in subjects with mild to moderate Alzheimer's disease. Approximately 530 subjects will be randomized to 12 months of daily treatment with either Active or Sham Sensory Stimulation Systems. Efficacy will be measured using the Alzheimer's Disease Cooperative Study- Activities of Daily Living (ADCS-ADL) assessment and a combined statistical test (CST) of the ADCS-ADL and the Mini-Mental State Exam (MMSE).
Usability study of software application that provide digitized cognitive intervention therapy for cognitively impaired patients.
The pandemic caused by SARS-CoV-2 infection has resulted, in addition to the well-known acute symptoms, in the emergence of a plethora of persistent, diffuse and heterogeneous symptoms such as fatigue, shortness of breath and cognitive dysfunction among others, that have come to be called persistent COVID. Patients have reported that physical activity, stress and sleep disturbances often trigger exacerbations of their symptoms related by some authors to the so-called Post Exertional Malaise (PEM) characteristic of Myalgic Encephalomyelitis. Similarly, by analogy with other pathologies, it has been hypothesized that optimal exercise prescription would benefit these people with persistent COVID-19 symptoms but in practice, the rehabilitation of these patients runs the risk of collapsing respiratory and physical rehabilitation services. This is why COPERIA proposes the construction of a platform for respiratory, cardiac and muscular telerehabilitation, to compare with face-to-face rehabilitation treatment and to try to predict the influence of physical activity in the prediction of PEM.
Alzheimer's disease (AD) is characterised by a progressive loss of memory and cognitive function. In the early stages of AD, there is a progressive accumulation of molecules: β-amyloid peptides (Aβ) in the brain. There is a link between the accumulation of Aβ peptides and the deterioration of sleep, but current knowledge does not confirmed this link. The objective of this study is to define whether there is a link between cognitive decline and sleep disorders. If a correlation is found, this could allow earlier treatment of sleep disorders in the longer term in order to slow the development of AD.
The pandemic caused by SARS-CoV-2 infection has resulted, in addition to the well-known acute symptoms, in the emergence of persistent, diffuse and heterogeneous symptoms referred to as persistent COVID. Common symptoms include fatigue, shortness of breath, and cognitive dysfunction, among others, and result in an impact on daily functioning. Symptoms may be new onset, appear after initial recovery from an acute episode of COVID-19, or persist after the initial illness. Cardiac variability (HRV) was initially used in COVID-19 to predict mortality in the acute setting. Dysautonomia which partly evaluates HRV is frequent in patients with persistent COVID. Several groups have used voice or other respiratory noise analysis for the diagnosis of acute COVID. Patients in the persistent COVID cohort will be able to be differentiated from an age, sex and vaccination status matched cohort of recovered COVID patients without sequelae by means of a model created by Machine Learning that will be trained using cardiac variability (HRV), skin conductance and acoustic analysis data. The primary objetive will be to obtain a classification algorithm by Machine Learning to differentiate the group of patients with persistent COVID diagnosis from the paired group of recovered COVID patients without sequelae.
The goal of this clinical trial is to determine the feasibility of a 12-week program of Tai Chi for memory (TCM) among older adults with mild cognitive impairment (MCI) or dementia and to determine the effects of TCM on physical functioning, depression, and health-related QoL. Two experimental groups will be recruited for inclusion criteria of community-residing older adults with a diagnosis of either MCI or Dementia.
