Background and Objective: Sex differences in the treatment of people with Parkinson's disease (PwP) with a device-aided therapy (DAT) have been poorly investigated. Our aim was to analyze sex differences in the management and response to a DAT in PwP in daily clinical practice (DCP). Patients and Methods: Data collected in the DATs-PD GETM Spanish Registry until 30 October 2025 were used. This is a descriptive, observational, prospective, and multicenter clinical registry with progressive inclusion of PwP treated with a DAT in DCP conditions in more than 40 centers from Spain. Sex differences in the DAT received and changes in quality of life (QoL), motor symptoms (MS), non-motor symptoms (NMS), and autonomy for activities of daily living (AADL) after 6 months of treatment were analyzed. Results: A total of 618 PD patients (66.9 ± 9.5 years old; 57.6% men) were treated with a DAT. A significant difference was observed in the DAT type according to sex (p = 0.006), with 73.1% of PwP who were treated with deep brain stimulation being men. At the time of DAT indication, women were older, received a higher levodopa equivalent daily dose, and had a worse health-related QoL and AADL. OFF time decreased, whereas MS and NMS burden and health-related QoL improved at 6 months follow-up in both groups (men and women). AADL improved only in men during the OFF state. Conclusion: Sex differences were detected in the use of DATs in PwP. Improvement in OFF time, MS, NMS, and QoL was detected in both groups.
