HA Receives $100,000 Gift to Advance Research on the Neuropsychological and Cognitive Impacts of Hydrocephalus
The Hydrocephalus Association (HA) is honored to recognize the extraordinary generosity of Tessa van der Willigen and Jonathan Walters, and David and Lisa Browdy, whose $100,000 commitment will fund two additional Neuropsychology and Cognition Awards over the next two years. Their investment underscores a powerful belief in the essential role this research plays in improving the lives of people living with hydrocephalus and advancing HA’s mission.

Launched in 2024, the Neuropsychology and Cognition Award was established to expand research into the quality-of-life dimensions of hydrocephalus across all ages. This award supports innovative studies focused on developing and refining neuropsychological and cognitive assessment tools that are vital to understanding how hydrocephalus affects thinking, learning, behavior, emotional health, and day-to-day functioning. These insights are critical not only for clinicians and researchers, but also for families seeking clearer guidance and better long-term outcomes.
Tessa and David played a pivotal role in bringing this award to life. As longtime HA Research Committee Co-Chairs—David from 2010–2023 and Tessa from 2018–2024—they championed the need to address the often-overlooked cognitive and psychological impacts of the condition. As parents of children living with hydrocephalus, they know firsthand how vital this research is for improving quality of life, strengthening supports, and shaping care that addresses the whole person. Their commitment was further reinforced by HA’s community research priorities, which highlighted an urgent need for expanded quality-of-life research.
Their continued commitment enables scientists to pursue cutting-edge studies that can lead to earlier identification of cognitive challenges, better monitoring of changes over time, and more personalized and effective interventions. These awards are helping to build a future where individuals with hydrocephalus can thrive—with the tools, information, and care plans needed to support every aspect of their well-being.
We extend our deepest gratitude to Tessa, Jonathan, David, and Lisa for their remarkable leadership and generosity. Their belief in this work is ensuring that cognitive and neuropsychological outcomes receive the attention it deserves, bringing hope, clarity, and improved quality of life to countless individuals and families.
