Early cognitive decline in amyotrophic lateral sclerosis and its relation to driving: an observational study.
Tina Taule, Ole-Bjørn Tysnes, Jörg Aßmus and 5 others
PMID 40988501WHAT IT FOUND
Cognitive scores in ALS patients stayed stable over eight months, but did not predict who stopped driving.
Screening early with the ECAS gives a reliable baseline, yet impaired patients continued to drive.
Key findings
01Cognitive function remained stable from baseline to follow-up, and early scores predicted later status.
02Baseline cognitive impairment was not associated with whether a patient stopped driving.
03Thirty-six percent of patients showed cognitive impairment at baseline, and two of those still driving at follow-up had impairment.

What it does not show
The sample size was very small (31 patients), resulting in low statistical power to detect associations. The follow-up period was short (approximately eight months), which may have been too brief to capture driving cessation linked to progressive cognitive decline. Driving status was assessed via a questionnaire rather than objective measures like crash records or simulator testing. An alternative form of the ECAS-N was not available, so repeated testing may have been influenced by practice effects, though previous research suggests stability in these constructs over this timeframe.
Declared interests
The authors declared no conflicts of interest. The work was supported by the Norwegian Regional Health Authority.
The easy way to misread this
Do not conclude that cognitive screening can identify which ALS patients are unsafe to drive. The study found no link between baseline cognitive impairment and driving cessation, meaning patients with impaired scores were just as likely to continue driving as those with normal scores.
