|Welcome to the Spastic Paraplegia
Foundation, Inc. (SPF)
The SPF is the only organization in the Americas
dedicated exclusively to upper motor neuron disorders called Primary Lateral Sclerosis (PLS) and
Hereditary Spastic Paraplegia* (HSP). We are proud to
take the leadership role on behalf of these conditions.
Not affiliated with any one institution, we are a
charitable, volunteer-driven organization devoted to
supporting research to discover the cures for upper
motor neuron degeneration. Uncovering the riddles to
these processes may also lead to critical findings for
