World Neurology: November-December issue now available online

Welcome to all readers from around the globe to the December 2025 issue of World Neurology, the final issue of this calendar year.

In the President's Column, Prof. Wolfgang Grisold, who completes his term as president of the World Federation of Neurology (WFN) at the end of this month, provides us with an overview of his remarkable and illustrious tenure with the association. He is passing the baton to the next president, Dr. Steven Lewis, who provides a brief preview of the next presidential term.

The editors would also like to extend our sincere gratitude to Prof. Guy Rouleau, who finishes his successful term as WFN vice president and leader of our WCN Congress Committee at the end of this month. His immense contributions to the WFN and our congresses position us well for the future.

In the History Column, Dr. Peter J. Koehler delves into the historical aspects of the nonmotor functions of the cerebellum. This issue also features news from Drs. Andreas Kattem Husøy, Yvonne Yiru Xu, and Timothy J. Steiner, who summarize the recent results from the Global Burden of Disease study. The study shows that headache disorders are a leading cause of health loss globally, with one-fifth being due to medication overuse. This issue includes reports from Drs. Luis Querol and Camila Castelo Branco Pupe, on behalf of the Peripheral Nerve Society, highlighting global programs such as leprosy awareness, funding initiatives, and outreach opportunities. Prof. Lawrence Tucker, president of the African Academy of Neurology, recounts a trip he and Prof. Grisold made to the University Training Hospital (UTH) in Lusaka, Zambia.

Dr. Rachel Forman, a stroke neurologist from Yale University, and two colleagues, provide information about a unique public school program intended to advance stroke education and community awareness. It is never too early to provide education and advocacy about brain health to the public. Connor McGinnis, a medical student from the United States, summarizes his experience rotating through the Neurology on Wheels initiative in rural India, led by Dr. Bindu Menon (and previously highlighted in World Neurology).

This issue also features an account from Dr. Cynthia Marleny Aliñado Ramos, a young neurologist from Guatemala. She recently successfully completed her one-year stroke fellowship at the highlevel neurology institutions comprising the WFN-accredited Training Center in Mexico City. There is also a Junior Traveling Fellowship report from a young neurologist from Kyrgyzstan, who presented her research at the Asian and Oceanian Parkinson's Disease and Movement Disorders Congress.

This issue features additional photo highlights of activities of the recent World Congress of Neurology (WCN) in Seoul, South Korea. (See the September-October 2025 issue for additional photos.) The next WCN will be held in October 2027 in Cape Town, South Africa.

We say goodbye to two giants of international neurology who recently passed away: Prof. Mark Hallett (a previous editor of World Neurology) and Prof. Michel Dumas.

We again thank all neurologists and neurologic trainees from all regions of the world for your interest in the WFN and World Neurology.

In closing, we would like to once again acknowledge Prof. Wolfgang Grisold, for his untiring devotion to global neurology, the WFN, and brain health for all throughout his tenure as WFN president. ■
