View clinical trials related to Cerebral Amyloid Angiopathy.
Filter by: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.
