On December 18, the "National Multiple Sclerosis Day" is celebrated to highlight the situation of those affected by this chronic neurodegenerative disease.

Multiple sclerosis is a disease of unknown cause, characterized by multiple lesions in the central nervous system. The loss of the substance that surrounds the nerves, known as myelin, is the most characteristic feature. These lesions do not all appear at the same time, but rather in outbreaks.

It generally begins between the ages of 20 and 40, with a higher incidence being observed in women.

In Spain there are more than 47,000 affected by this disease, more than 60,000 in Europe and approximately 2.5 million worldwide.

We can all contribute in biomedical research progress. If you wish you can donate the left over material after diagnosis obtained during the treatment process (blood samples, biological liquids and tissue) for carrying out biomedical research without causing you any additional inconvenience. There is a network of biobanks managing human biological samples for biomedical research.
