Background Amyotrophic lateral sclerosis (ALS) is a multisystem disorder with not only motor symptoms but also extra-motor features including cognitive impairment.
The most common cognitive profile observed in patients with ALS includes deficits in executive function, language, and social cognition.
However, longitudinal studies on cognitive changes over time in ALS are sparse.
We aimed to investigate the presence and nature of cognitive impairment at the time of ALS diagnosis and its association with survival as well as explore longitudinal cognitive change.
Method Patients ( n = 216) were recruited at the Karolinska University Hospital in Stockholm, Sweden.
Follow-up visits ( n = 307 in total) were performed every 6 months.
Cognitive impairment was assessed using the Edinburgh Cognitive and Behavioural ALS Screen (ECAS) and/or Montreal Cognitive Assessment (MoCA).
Results Cognitive impairment was observed in 38% of the patients at the time of ALS diagnosis, and the majority of these patients had deficits in executive function and/or language.
Patients with cognitive impairment at the time of diagnosis had a more rapid decline in ALSFRS-R at 12- and 18-months follow-up, and a shorter survival.
Cognitive function was stable during the first 2 years after diagnosis, and did not follow the trajectories of decline in motor functions.
Conclusion Cognitive impairment in ALS was associated with a faster decline of motor functions, and shorter survival.
However, cognitive function did not deteriorate over time.
Cognitive assessment is essential for the patients and caregivers to understand the phenotypic expression of ALS.
