Filter by:Cerebral amyloid angiopathy (CAA) is a common form of cerebral small vessel disease, characterized by symptomatic intracerebral hemorrhage and cognitive impairment. However, no effective prevention and treatment strategies have been established. This study aims to evaluate the safety and efficacy of remote ischemic conditioning on patients with CAA.
Cerebral Amyloid Angiopathy (CAA) is one form of disease of the small vessels of the brain and can cause frequent cerebral hemorrhages as well as other types of stroke. The aim of the research was to examine the balance of the body in patients after a stroke and to determine how the tension of selected muscles of the cervical spine changes under the conditions of statics and dynamics, depending on the visual control or its absence.
Transient focal neurological episode (TFNE) is the most frequent presenting symptom of convexity subarachnoid haemorrhage (cSAH) in elderly patients with non-traumatic cSAH with suspected, possible or probable cerebral amyloid angiopathy (CAA). The aim of our study was to analyse in detail clinical and MRI characteristics in these patients. Methods: We performed a retrospective study analysing baseline, acute clinical symptom (TFNE and headache), and MRI characteristics (acute cSAH and chronic CAA features) of consecutive elderly (≥55 years) patients, recruited and registered in the stroke database, between june 2008 and october 2020 of two centres (Nîmes and Montpellier University Hospital, France), presenting with cSAH with suspected, possible, or probable CAA.
Cerebral amyloid angiopathy-related intracerebral (CAAH) hemorrhage is second factor of primary intracerebral hemorrhage. However, no effective prevention and treatment strategies have been established. Remote ischemic conditioning is a neuroprotective strategy. In animal studies，RIC is efficiency in accelerating the absorption of hematoma. Therefore, the investigators plan to carry out this research to evaluate the safety and efficacy of RIC in patients with CAA related ICH.
Ischemic cardiovascular and cerebrovascular diseases are the main causes of death among people. Antiplatelet threrapy is very important for patients to prevent ischemic cardiovascular and cerebrovascular diseases.Ischemic cardiovascular patients of cerebral amyloid angiopathy (CAA) patients is as high as 20%, aspirin and clopidogrel is applied to prevent or treat the patient with CAA is controversial, there is no valid evidence of CAA crowd is safe to use of antiplatelet drugs, but progress in clinical treatment is usually based on patient condition for antiplatelet agents to prevent the occurrence of adverse events, such as blood clots.Therefore, this study is intended to be a single-center, prospective study of patients with ischemic cardiovascular and cerebrovascular diseases taking aspirin and clopidogrel, to determine whether the patients are combined with CAA , and to conduct a follow-up study for 12 months after team inclusion:1) The prevalence rate and gene spectrum of ischemic cardiovascular and cerebrovascular diseases among CAA patients enrolled in our hospital were analyzed;2) To explore the correlation between aspirin and clopidogrel drug genes and blood drug concentrations and diseases in patients with ischemic cardiovascular and cerebrovascular diseases complicated with CAA;3) To evaluate the efficacy and safety of aspirin and clopidogrel in patients with ischemic cardiovascular and cerebrovascular diseases who combined with CAA.
In this three-year proposal, we will explore the MRI-visible EPVS in CAA and investigate its pathophysiology using animal models. Our specific aims include: (1) Establish the relationship of MRI-visible enlarged perivascular space and CAA, (2) Determine whether vascular amyloid clearance in CAA is associated with lymphatic drainage system, (3) Establish longitudinal data for MRI-visible enlarged perivascular space and cerebral amyloid angiopathy progression.
Cerebral amyloid angiopathy (CAA) is one of the major types of cerebral small vessel disease, and a leading cause of spontaneous intracerebral hemorrhage and cognitive decline in elderly patients. Although increasingly detected, a number of aspects including the pathophysiology, the clinical and neuroradiological phenotype and the disease course are still under investigation. The incomplete knowledge of the disease limits the implementation of evidence based guidelines on patient's clinical management and the development of treatments able to prevent or reduce disease progression. The SENECA (SEarchiNg biomarkErs of Cerebral Angiopathy) project is the first Italian multicentre cohort study aimed at better defining the disease natural history and identifying clinical and neuroradiological markers of disease progression. By a multidisciplinary approach and the collection of a large and well phenotyped series and biorepository of CAA patients, the study is ultimately expected to improve the diagnosis and the knowledge of CAA pathophysiological mechanisms.
By combination of plasma (Aβ40, Aβ42, total tau, and phosphorylated tau, etc.), genetic (ApoE ε2 or ε4 allele), MRI (cerebral perfusion, microbleeds, cortical superficial siderosis, enlarged perivascular space, etc.) and PET imaging (amyloid and tau) biomarkers, the study aims to 1. Enhance the diagnostic potentials of the radiological biomarkers by combining MRI and amyloid PET in CAA patients. 2. Investigate the biological pathogenesis in CAA patients using the less invasive plasma biomarkers and to correlate with structural and function imaging, including MRI, amyloid and tau imaging. 3. Study the characteristics of long-term progression of amyloid deposition in CAA patients using the radiological, biochemical and genetic biomarkers. 4. Study the prognosis predicting markers.
Until now there is no medical treatment and/or intervention that can slow, stop or reverse the underlying neurodegenerative of Alzheimer's disease (AD). The goal of this study is to demonstrate "Oleocanthal rich-extra-virgin olive oil (EVOO) consumption stops or delay mild cognitive impairment conversion to AD by restoring the blood-brain barrier (BBB) function in humans". Specific Aims: 1. Evaluate effect of EVOO on the brain function by functional MRI (fMRI) imaging, and BBB function by dynamic contrast-enhanced MRI (DCE-MRI). 2. Evaluate effect of EVOO on cognitive function and on selected biomarkers
In this project, we will try to enhance the diagnostic potentials of amyloid PET in CAA by combination of dynamic amyloid PET with MRI SWI and MR perfusion images. We will also try to investigate the roles of CAA in patients with drug-related ICH and validate the accuracy of clinical CAA diagnostic criteria. In addition, we will try to study the characteristics of long-term progression of amyloid deposition in CAA patients. This project will enroll 100 patients with ICH, 30 patients with AD, and 30 control subjects. Each patient will receive the above image studies, followed by data analysis and comparison.
