Quality of Life (QOL) in Parkinson's disease (PD) patients after Deep Brain Stimulation (DBS) neurosurgery generally improves between 3 to 24 months post-operatively. However, QOL beyond 2 year follow-up is generally unknown. This study examined the QOL in 16 advanced PD patients who received DBS at an average of 7.5 year follow-up with the Parkinson's Disease Questionnaire (PDQ-39). Participants had an average Disease Duration of 20.57 years (SD 5.7) and a mean Age of 63.50 (SD 8.05). Linear regression analyses suggested a constellation of changes involving Time, Age, and Disease Duration. As Time progressed since DBS intervention, the PDQ-39 Cognitions subscale worsened (p < .05). Increasing Age was associated with improvement in Stigma-related QOL (p < .01). Rising Disease Duration correlated with improvements in three PDQ-39 subscales: (a) Stigma (p < .01), (b) Emotional Well-Being (p < .01), and (c) Social Support (p < .05). Findings suggested the need to further explore the domains and dimensions of QOL change post-DBS intervention, as well as other methods to measure the depth and breadth of QOL in DBS recipients.
