Amyotrophic Lateral Sclerosis (ALS) is a progressive neurodegenerative disease that presents with cognitive impairment (CI) in up to 50% of cases. In this study, we consider 17 healthy controls’ and 61 ALS patients’—16 with CI and 45 without CI— performances on the cookie theft picture description task. Measures of language impairment are automated and used to evaluate the entire ALS population. Results show that both ALS patients with and without CI show statistically significant differences from healthy controls over four language features.
