Today, October 17, is World HSP & PLS Awareness Day.
Today, we join families, researchers, and organizations around the world to raise awareness of Hereditary Spastic Paraplegia (HSP) and Primary Lateral Sclerosis (PLS), rare neurological diseases that affect movement and can lead to progressive disability.
For our Foundation, this day is especially meaningful. Childhood-onset SPG4 is rare, progressive, and currently has no approved treatment.
But awareness is only the beginning.
Over the past year, we’ve continued building a global community of families and researchers, funding promising science, and advancing multiple approaches toward potential treatments. What once felt like an impossible challenge has become a coordinated effort to change the future for children living with SPG4.
Because awareness matters. Research matters. And for children living with progressive disease, time matters.
Today, we join the entire HSP and PLS community in a shared commitment to greater awareness, continued research, and a future with better treatments.
