Popis: Subthalamic nucleus deep brain stimulation (STN-DBS) is an established treatment for patients with Parkinson’s disease (PD) with motor complications; the contribution of sex in determining the outcome is still not understood. We included 107 patients (71 males) with PD consecutively implanted with STN-DBS at our center. We reviewed patient charts from our database and retrospectively collected demographical and clinical data at baseline and at three follow-up visits (1, 5 and 10 years). We found a long-lasting effect of DBS on motor complications, despite a progressive worsening of motor performances in the ON medication condition. Bradykinesia and non-dopaminergic features seem to be the major determinant of this progression. Conversely to males, females showed a trend towards worsening in bradykinesia already at 1-year follow-up and poorer scores in non-dopaminergic features at 10-year follow-up. Levodopa Equivalent Daily Dose (LEDD) was significantly reduced after surgery compared to baseline values; however, while in males LEDD remained significantly lower than baseline even 10 years after surgery, in females LEDD returned at baseline values. Males showed a sustained effect on dyskinesias, but this benefit was less clear in females; the total electrical energy delivered was consistently lower in females compared to males. The profile of adverse events did not appear to be influenced by sex. Our data suggest that there are no major differences on the motor effect of STN-DBS between males and females. However, there may be some slight differences that should be specifically investigated in the future and that may influence therapeutic decisions in the chronic follow-up.
