Abstract
Leukodystrophies (LDs) are a group of rare, genetic disorders unified by their hallmark involvement of the cerebral white matter. They are typically characterized as progressive disorders, resulting in severe neurologic decline and premature death within months to years after onset. Managing LDs therefore requires lifelong, multidisciplinary care, a challenge compounded by their rarity and phenotypic heterogeneity, for which detailed clinical and scientific information is sometimes lacking. Research networks have proven useful in the rare disease community to unite efforts, increase awareness, and accelerate progress toward understanding and treating these often understudied conditions. Therefore, we established the Canadian Association for Research Excellence in Leukodystrophy (CARELeuko), a national network dedicated to improving LD care, research, and treatment within Canada. To better understand and address the most pressing needs for LDs in Canada, we engaged a diverse group of stakeholders including researchers, clinicians, and patient advocates to highlight and prioritize gaps in LD care and research. In this review, we discuss the key gaps identified in the Canadian LD landscape and outline strategies to address these challenges. This effort will inform the development of targeted initiatives aimed at improving outcomes for Canadian families affected by these debilitating disorders.Keywords
