Abnormal reaction time as a biomarker for functional movement disorders

Takeaway

  • In those with functional movement disorders (FMD), there is an increase in reaction time which may be attributed to response uncertainty and impairment in the quality of information driving decision-making processes (reduced drift rate).

Why this matters

    The reduced drift rate in those with a variety of FMD indicates that it may serve as a biomarker for impaired information processing in a common disease framework for neurobiological deficits of multiple FMD.
