The Impact of Deep Brain Stimulation for Parkinson's Disease on Couple Satisfaction: An 18-Month Longitudinal Study

Publication date2019

Patients with Parkinson's disease (PD) may benefit from deep brain stimulation (DBS) to improve motor and medication-induced symptoms. Yet mixed evidence regarding the outcome of successful DBS on couple satisfaction has been highlighted in the literature. Thirty patients diagnosed with PD were included in a study investigating couple satisfaction (MSS-14), depression (HAD-D) and anxiety (HAD-A) at four measurement times: before DBS and 6, 12, and 18 months post-surgically. Sixteen spouses/partners were included as well. Couple satisfaction from the patient perspective was never associated with depression or anxiety. However, poor marital adjustment (i.e., difference and absolute difference between patients and spouses/partners MSS-14 scores) predicted patients' pre-operative depressive mood. Longitudinal analyses showed that couple satisfaction (n = 9) worsened at 12 months and 18 months compared to pre-DBS scores, F(2.047, 16.378) = 8.723, p = .003, and despite concomitant motor improvement. Growth curve analyses showed that couple satisfaction worsening occurred between 6 and 12 months post-operatively (b = 2.938, p < .001). Thus, couple satisfaction did not increase along with motor improvement and deteriorated after the adjustment period following DBS.
