Self-perceptions on cognitive versus motor disability among neurologists

Area of Science:

• Neurology
• Clinical Outcomes Research

Background:

• The modified Rankin Scale (mRS) is a standard functional outcome measure in neurological studies.
• The mRS disproportionately emphasizes motor deficits over other functional aspects.
• Physician perceptions of optimal outcomes may differ from trial definitions.

Purpose of the Study:

• To investigate whether physicians' personal perceptions of acceptable neurological outcomes align with the modified Rankin Scale.
• To explore the weight given to cognitive versus motor function in quality-of-life assessments among neurologists.

Main Methods:

• An anonymous survey was distributed to neurologists and neurology fellows.
• The survey presented two clinical scenarios corresponding to mRS 2 and mRS 4 disability levels.
• Participants indicated their preference for quality of life between the two scenarios.

Main Results:

• Nearly all surveyed neurologists (97.7%) would choose wheelchair dependence if cognitive function remained intact.
• This preference was observed even when cognitive impairment would prevent them from practicing medicine.
• A strong preference for maintaining cognitive baseline was evident.

Conclusions:

• The modified Rankin Scale may inadequately represent preferred outcomes for neurology specialists, particularly concerning cognitive function.
• Cognitive outcomes appear to be a critical factor in perceived quality of life for neurologists.
• Further research is needed to better characterize long-term cognitive outcomes in neurological conditions.
