Patients with Parkinson’s disease face complex treatment decisions, including whether to pursue deep brain stimulation (DBS). To understand why some decline DBS, semi-structured interviews were conducted with PD patients who chose not to undergo the procedure. Qualitative analysis showed that perceived invasiveness, maintenance burden, and social influences shaped decisions. Patients weighed potential benefits against risks and lifestyle stability. Findings highlight the multidimensional nature of invasiveness and the need for clearer information to support patient-centered decision-making.
