Hydrocephalus World Congress on September 05-08, 2025 in Toulouse, France

Dear Colleagues & Friends,

It is my honour and sincere pleasure to welcome you to Hydrocephalus 2025, the 17th World Hydrocephalus Congress arranged by the Hydrocephalus Society (The International Society for Hydrocephalus and Cerebrospinal Fluid Disorders).

The Hydrocephalus Society was formed in 2007 with a goal to create an International Society that addressed the entire field of hydrocephalus. During these past 18 years, the Society has grown, engaging more member scientists and clinicians around the world to advance hydrocephalus research and clinical care. Hydrocephalus Society is increasingly engaged in different activities including the educational Global Webinar Series presently running its fourth season, efforts to increase awareness as well as collaborations with other societies. Our Society has worked with the Society Secretariat (Artion) since late 2015 for management of both Society affairs and the Annual Meeting. Fluids and Barriers of the CNS is the official journal of the Hydrocephalus Society and now has an impact factor of 7.3. Over the years, we have witnessed significant progress with our understanding of what hydrocephalus and other cerebrospinal fluid disorders are and do to children and adults and how to improve the care of affected patients. Please consider becoming a full member of the Hydrocephalus Society if you presently are not one.

 The peak of our year is the Annual World Congress bringing together experts within this exciting field for some intense days when we share scientific advances and new developments as well as network to foster collaboration. The Young Investigators Award competition has become a crown jewel of the meeting highlighting junior researchers and our annual Keynote speakers are exceptional world experts.

We are very grateful to our host and meeting president Prof. Eric Schmidt and his entire team, to our secretariat Artion and to all people who have contributed to this conference. This year, we have prepared a very exciting scientific program that includes the new, cutting-edge developments in adult and paediatric hydrocephalus and CSF disorders within both clinical and experimental research. Our Keynote speakers are selected for their outstanding records. However, to make the conference a real success, we need your participation, your input, your questions and participation in discussions, i.e. your contributions to the congress. We thank you for making this conference a special, fruitful, and inspiring event.

 On behalf of the Hydrocephalus Society, I wish you great days in the lovely city of Toulouse and hope you will bring many new insights and enjoyable memories back home.

Let’s meet in Toulouse in September! 

Mats Tullberg, Professor

President of the Hydrocephalus Society
