This document is a response to a previous study on cognitive profiles in amyotrophic lateral sclerosis (ALS) patients. The authors confirm that cognitive deficits occur in all forms of ALS, but are more prevalent in certain types. They also note some differences in their own cohort, such as a lower frequency of cognitive impairment in certain types of ALS and more severe impairment in bulbar onset cases. The authors suggest that additional factors like age, disease course, and genetic mutations should be considered when studying cognitive deficits in ALS. [Extracted from the article]
