The economic impact of amyotrophic lateral sclerosis: a systematic review
Amyotrophic lateral sclerosis (ALS) is a devastating neurological disease for which there is no cure, and the associated economic burden is considerable. In this review, the authors summarize the existing body of literature pertaining to the costs associated with ALS to demonstrate the scale and scope of the economic burden of this paralyzing disease. Twelve studies from eight countries published between January 2001 and January 2015 met the inclusion criteria and were included in this review. Direct and indirect costs varied significantly across countries. Standardized to the 2015 US$, the annual total cost per patient ranged from US$ 13,667 in Denmark to as high as US$ 69,475 in the USA, with the national economic burden of ALS estimated at US$ 279-472 million in the USA. Costs associated with ALS were greater than that of other neurological diseases, indicating a continued need for medical advances and financial support for patients and families. Regional cost analyses are necessary to determine how best to spend funds that have been raised globally from the ice bucket phenomenon.
