Filter by:This study was a prospective, randomized, single-blind, parallel-controlled, multicenter clinical study to evaluate the efficacy and safety of repetitive transcranial magnetic stimulation and transcranial direct current stimulation assisted rehabilitation in the treatment of cerebrovascular disease-related gait disorders.
Complex brain arteriovenous malformations (bAVMs) in ≥3 Spetzler-Martin grades have long been challenges among cerebrovascular diseases. None of the traditional methods, such as microsurgical operation, endovascular intervention, or stereotactic radiotherapy, can completely eliminate complex bAVMs without a risk of neural function deterioration. The multistaged hybrid operation solved part of the challenge but remained risky in the installment procedures and intervals. The one-staged hybrid operation was applied in the surgical treatment of cerebrovascular diseases and proved to be a potentially safe and effective method for curing complex bAVMs. However, lacking the support of high-level evidence, its advantages remain unclear. This study was proposed to validate the benefits and risks of one-staged hybrid operation in the treatment of complex bAVMs, as well as its indications, key technologies, and workflows.
To investigate the therapeutic effect of individualized treatment of antiplatelet in secondary prevention of ischemic stroke.
The clinical efficacy of LDL-lowering therapy have been proven with strong evidences and more emphasized. However, there are also growing concerns that high-intensity statin would be related to increased risk of adverse effects. In addition, there was an inconsistency of efficacy of statin according to ethnic population. Asian population showed more profound LDL reduction not only from high potent statin but from moderate to low potent statin. Conventional strategies for lowering LDL-cholesterol was focused on statins, therefore doubling of previously described dose of statin would be common way in patients with inadequate lowering LDL-cholesterol level. Additive ezetimibe will also an alternative strategy not only to lower LDL-cholesterol level and also to reduce the need of dosage of high-intensity statin to fulfill sufficient LDL-cholesterol lowering effect. We will evaluate whether additive ezetimibe with rosuvastatin will have comparable clinical efficacy in terms of clinical outcomes and goal attainment of LDL-C compared to rosuvastatin monotherapy.
To compare the effects of various combinations between 6 hertz(Hz) rTMS & LFrTMS on the limb motor dysfunction due to cerebral vascular disease.
Introduction: Cerebral small vessel disease (SVD) is associated with age-related disabilities including dementia, depression, physical and functional impairment. Chinese are more prone to developing SVD than Caucasians. Physical exercise may improve multiple negative consequences associated with SVD. Objective and hypothesis to be tested: To examine the effects of a 24-week structured aerobic dance training on cognition, mood, physical and daily functions in stroke and dementia free older adults with SVD, and whether such effects are mediated through improved cerebral vasomotor reactivity (CVR), a marker of cerebral autoregulation which is impaired in SVD. Design and subjects: Rater-blind RCT comparing the effects of 24-week of structured aerobic dance training upon cognition, mood, physical and daily functions on 110 community dwelling, stroke- and dementia-free persons aged ≥65 with MRI evidence of significant SVD, defined as the presence of multiple (≥2) lacunes and/or early confluent or confluent WML. Interventions: Participants are randomized in a 1:1 ratio into a 24-week of structured therapist-led group aerobic dance training with home practice or simple stretching plus health education control group. Main outcome measures: Cognition, mood, physical and daily functions and CVR measured using Transcranial Doppler at baseline, weeks 12, 24 and 36. Data analysis: Intent-to-treat with multiple imputations with treatment efficacy analyzed using mixed effects models. Mediation effects of CVR between aerobic dance training and treatment outcomes tested using mediation models. Expected results: In persons with significant SVD, aerobic dance training improves cognitive, mood, physical and daily functions and such effects are mediated by changes in CVR.
One of the crucial challenges for the future of Alzheimer's disease (AD) therapeutic approaches in elderly is to target the main pathological process responsible for disability and dependency. However, a progressive cognitive impairment occurring after the age of 70 is often related to mixed lesions of neurodegenerative and vascular origins. Whereas young patients are mostly affected by pure lesions, aging favors the occurrence of co-lesions of AD, vascular and Lewy body types. Pure DLB (Dementia with Lewy Body) and AD are distinct disorders but they often coexist in old age patients, the Abeta pathology of DLB/AD cases being different to that observed in patients with AD alone. Vascular dementia (VD) and AD with cerebrovascular disease (AD+CVD) are the leading causes of dementia next to AD alone. Lack of consensus persists about the diagnosis criteria for VD and AD+CVD, due in part to their clinical, pathological heterogeneity and the multiple pathological subtypes. We do not know the precise role and weight of each brain lesion type in the disability progression in elderly. To target the actual pathological process, we need to disclose the functional weight of AD, Lewy body and vascular lesion types in elderly. Most of the studies report on functional and clinical abnormalities in patients with pure pathologies. Thus, co-morbid processes involved in the transition from an independent functional status to disability in the elderly with co-lesions still remain to be elucidated. Neuropathological examination often performed at late stages cannot answer this question at mild or moderate stages. Brain MRI, Single Photon Emission Computed Tomography (SPECT) with DaTscan® and CSF biomarkers help routinely in performing the diagnosis of pure or mixed lesions responsible for dementia. The topography of the atrophy in MRI helps to provide information about the etiological diagnosis. Medial temporal lobe atrophy on MRI has good discriminatory power for AD compared to DLB and VD in pathologically confirmed cases. DaTscan® SPECT presents with good sensitivity and specificity at early stages of DLB. The good diagnosis value of CSF biological markers has led recently to their inclusion in the research diagnosis criteria of AD. Low Aβ1-42 and high levels of total tau and hyperphosphorylated tau isoforms appear to be the most sensitive and specific CSF biomarkers. Aβ1-42 is lowered in AD, as well as in other neurodegenerative diseases like DLB, VD. The combination of MRI, particularly medial temporal atrophy measures and vascular lesions on FLAIR MRI sequences, SPECT and CSF biomarkers seem to be of incremental value for the diagnosis AD, VD, DLB and mixed profiles. The aim of this study is to identify the biomarkers (MRI, SPECT-DaTscan® and CSF), and their combination, that are the most predictive of functional disability in elderly presenting with a progressive cognitive decline related to AD, DLB, VD and all mixed patterns.
