Filter by:The dilation of perivascular spaces can be the result of various etiopathogenetic processes. White matter atrophy can cause enlargement of these perivascular spaces (PVS) but also obstruction of fluid drainage systems (interstitial fluid, ISF) and metabolites, as evidenced by some recent studies. Focal stagnation of liquids and deposition of toxic material induce tissue hypoxia and neuroglial dysfunction. Dilation of PVS can be associated with changes in white matter and microhemorrhages. We want to study these etiopathogenetic phenomena by implementing specific MRI methods.
To investigate the pathways of Gadolinium-based contrast agent (GBCA) in different brain compartments and evaluate correlations of GBCA enhancement with specific diseases.
This study investigates changes in glymphatic flow in the brain acutely after vigorous-intensity steady-state aerobic exercise. Twenty subjects (10 male and 10 female) perform 25 minute submaximal cycle ergometry exercise and the changes in the glymphatic flow and cerebral perfusion are evaluated using a variety of MRI sequences (e.g. MREG).
This study is designed to measure the change in patients diagnosed with Parkinson's disease (PD) before, during and after a 12 week exercise program.The focus of this study is the glymphatic system. The glymphatic system is a recentlydiscovered novel waste clearance pathway, in patients with Parkinson's Disease (PD).The glymphatic system acts as a waste-clearance system in the brain of vertebrate animals.The glymphatic system has been proposed in which new clearance pathways involving communication between paravascular spaces, interstitial fluid, and ultimately meningeal and dural lymphatic vessels exists, and we have provided evidence that this system may be dysfunctional in patients with Parkinson's disease with cognitive disorders. Early research suggest glymphatic function increases following exercise, this response is believed to clear beta-amyloid in the brain and may mediate the neurobehavioral response to exercise in PD. This study will use cognitive exams, neurological exams as well as specialized imaging to record data points and evaluate the glymphatic function after exercise.
