Abstract     The study aimed to evaluate the nature and extent of executive deficits in nondemented amyotrophic lateral sclerosis (ALS) patients. A total of 22 ALS patients and 21 matched controls were compared on standard neuropsychological tests of executive functions with appropriate control for motor impairment and on an ecologically valid motor-free test of executive functions, the Medication Scheduling Task (MST). Our results show that motor dysfunction can present a significant confound when using standard neuropsychological measures; however, even when accounting for motor disabilities, ALS patients show a robust pattern of cognitive dysfunctions. Additionally, MST was shown to be a sensitive measure of cognitive impairment, providing an important insight into cognitive processes relevant for patients' daily living.
