Sensitivity to reward is tied to impulsive errors in patients with Parkinson's disease

What is it about?

People with Parkinson's disease have been shown to react differently in times of decisional conflict compared to people without Parkinson's. This paper examines whether and how sensitivity to reward or punishment might further influence how patients with Parkinson's disease respond to conflict. We contend that patients who are less sensitive to punishment make more fast, impulsive motor responses in times of conflict.

Why is it important?

Our findings suggest that, for patients with Parkinson's, elements of an individual's sensitivity to punishment may influence behaviors that are important in controlling impulsive responses. These findings may provide a way for clinicians to screen patients who are at greater risk for making fast, impulsive motor responses. This is particularly important for patients with Parkinson's disease, who are already at greater risk for injuries related to falls, etc. Thus, providers may be better equipped to make more informed treatment decisions.
