Clinical usefulness of scales for evaluating cognitive impairment in patients with amyotrophic lateral sclerosis

Cognitive impairment is a common non-motor symptom of amyotrophic lateral sclerosis (ALS); however, scales suitable for detecting cognitive impairment in ALS patients in clinical practice are unclear. In this study, the Mini-Mental State Examination, Frontal Assessment Battery, and Montreal Cognitive Assessment (MoCA) were evaluated in 68 patients with ALS. The patients were classified into 3 groups based on the results of these clinical scales: group N, patients with scores higher than the cut-offs in all clinical scales; group M, patients with a score lower than the cut-off in one clinical scale; and group D, patients with scores lower than the cut-offs in two or three clinical scales.
