Summary

This study looked at how deep brain stimulation (DBS) changes the way people with Parkinson's disease explain positive and negative events, known as attributional style. Researchers measured this in 32 French-speaking adults with Parkinson's who had stable treatment. The goal was to understand if DBS affects social thinking, which could impact daily life and relationships.
