Primary Lateral Sclerosis French National Diagnostic and Care Protocol

France establishes the first standardized diagnostic and care protocol for a rare motor neuron disease, improving consistency for an underserved population.

The French FILSLAN network published the first national diagnostic and care protocol for primary lateral sclerosis, a rare motor neuron disease accounting for 1-5% of MND cases, standardizing the 4-year UMN sign persistence threshold, ALS differentiation criteria, and multidisciplinary management framework. The protocol highlights the absence of disease-modifying therapies and recommends biannual multidisciplinary follow-up, directly improving care consistency for this underserved patient group.
