Understanding faster biological aging in amyotrophic lateral sclerosis

Abstract

In a study of 5,146 ALS patients and 2,156 healthy controls, altered white blood cell proportions were found to confound biological aging assessments.

  • No significant difference in biological aging pace was observed between ALS patients and controls, except in those with a specific genetic mutation.
  • The increase in biological aging previously noted in ALS patients may be influenced by variations in white blood cell types.
  • After adjusting for cell counts, accelerated epigenetic aging was not evident in the majority of ALS patients compared to controls.
  • scores did not correlate with survival outcomes in ALS patients.
