CCSVI is associated with multiple sclerosis

Neurological Research
Sandra Morovic, Paolo Zamboni


To analyze all the arguments against chronic cerebrospinal venous insufficiency (CCSVI) as a medical entity, and its association with multiple sclerosis (MS) and to revise all the findings suggesting a possible connection between these two entities. We revised the methodology and results of all fourteen published studies on prevalence of CCSVI in MS patients. Furthermore, we take into consideration other work dealing with possible causes and explanations of venous, as well as vascular dysfunctions linked with MS. Studies of prevalence show a great variability in prevalence of CCSVI in MS patients. However, a recent meta-analysis assessed an over 13 times increased prevalence in MS. Global hypoperfusion of the brain, and reduced cerebral spinal fluid dynamics in MS was shown to be related to CCSVI. Post-mortem studies show a higher prevalence of intraluminal defects in the main extracranial vein in MS patients in respect to controls. Taking into account the current epidemiological data, the autoptic findings, and the relationship between CCSVI and both hypoperfusion and cerebrospinal fluid flow, CCSVI can be inserted in the list of multiple factors involved in MS pathogenesis. Our careful data analysis may conclude that great va...Continue Reading

Blood Brain Barrier Regulation in Health & Disease

The blood brain barrier is essential in regulating the movement of molecules and substances in and out of the brain. Disruption to the blood brain barrier and changes in permeability allow pathogens and inflammatory molecules to cross the barrier and may play a part in the pathogenesis of neurodegenerative disorders. Here is the latest research in this field.

Blood Brain Barrier Chips

The blood brain barrier (BBB) is comprised of endothelial cells that regulate the influx and outflux of plasma concentrations. Lab-on-a-chip devices allow scientists to model diseases and mechanisms such as the passage of therapeutic antibodies across the BBB. Discover the latest research on BBB chips here.

Autoimmune Diseases

Autoimmune diseases occur as a result of an attack by the immune system on the body’s own tissues resulting in damage and dysfunction. There are different types of autoimmune diseases, in which there is a complex and unknown interaction between genetics and the environment. Discover the latest research on autoimmune diseases here.
