In Memoriam Prof. Ralph L. Sacco

We are sad to report that Prof. Sacco died on January 17.

As the president of the AAN, Pr Sacco had a close relationship with the WFN, and he will be remembered as being cosmopolitan, open and very constructive.

The WFN also wants to thank him for his active participation in several WFN committees.

His contribution to the field of stroke is extensive and led to a better understanding of stroke prevention, treatment, risk factors and disparities.
