Assessing fitness to drive a motor vehicle is an important part of clinical practice for multiple sclerosis, but MS and cognitive impairment alone don’t indicate that a patient will fail a formal road test. However, the results from a recent study indicate that one cognitive test may be able to predict the patients who would fail road tests though only with a high false-positive rate.
The researchers noted that, if a patient does not show impairment on the BVMTR-IR, then they will definitely pass the road test, but they also noted that showing impairment is much less likely to predict a failed test. Instead, impairment both on this test and on the Symbol Digit Modalities Test, which measures processing speed, should indicate the need for a formal driving assessment.
“This study further contributes to the clinician’s ability to identify [persons with MS] in whom fitness-to-drive should be addressed,” the investigators wrote.
