Association between attention-deficit/hyperactivity disorder and amyotrophic lateral sclerosis

Ebel et al. evaluated the association between attention-deficit/hyperactivity disorder (ADHD) and amyotrophic lateral sclerosis (ALS) [1]. Sociodemographic factors and physical activities were also considered in the analysis. The authors cited a paper, presenting the hypothesis that there was a pathophysiological link between ADHD and ALS [2], however ALS patients reported a lower prevalence of childhood ADHD and there was no evidence that ADHD had been more common in ALS patients. I have 2 concerns about this study.
