RESUMO

Deep brain stimulation(DBS) can not only significantly improve the motor symptoms of Parkinson's disease(PD), but also effectively reduce the refractory motor complications caused by levodopa. During the past 20 years, DBS has turned into one of the most successful treatment strategies in advanced stages of the PD. Careful patient selection, accurate electrode implantation during surgery, and individualized programming and drug adjustment are the guarantees for optimal efficacy and minimal side effects of DBS. New technologies such as directional deep brain stimulation and visual programming modes will further optimize the efficacy of DBS.

RESUMO

<p><b>BACKGROUND</b>Subthalamic nucleus deep brain stimulation (STN DBS) is effective against advanced Parkinson's disease (PD), allowing dramatic improvement of Parkinsonism, in addition to a significant reduction in medication. Here we aimed to investigate the long-term effect of STN DBS in Chinese PD patients, which has not been thoroughly studied in China.</p><p><b>METHODS</b>Ten PD patients were assessed before DBS and followed up 1, 3, and 5 years later using Unified Parkinson's Disease Rating Scale Part III (UPDRS III), Parkinson's Disease Questionnatire-39, Parkinson's Disease Sleep Scale-Chinese Version, Mini-mental State Examination, Montreal Cognitive Assessment, Hamilton Anxiety Scale and Hamilton Depression Scale. Stimulation parameters and drug dosages were recorded at each follow-up. Data were analyzed using the ANOVA for repeated measures.</p><p><b>RESULTS</b>In the "off" state (off medication), DBS improved UPDRS III scores by 35.87% in 5 years, compared with preoperative baseline (P < 0.001). In the "on" state (on medication), motor scores at 5 years were similar to the results of preoperative levodopa challenge test. The quality of life is improved by 58.18% (P < 0.001) from baseline to 3 years and gradually declined afterward. Sleep, cognition, and emotion were mostly unchanged. Levodopa equivalent daily dose was reduced from 660.4 ± 210.1 mg at baseline to 310.6 ± 158.4 mg at 5 years (by 52.96%, P < 0.001). The average pulse width, frequency and amplitude at 5 years were 75.0 ± 18.21 μs, 138.5 ± 19.34 Hz, and 2.68 ± 0.43 V, respectively.</p><p><b>CONCLUSIONS</b>STN DBS is an effective intervention for PD, although associated with a slightly diminished efficacy after 5 years. Compared with other studies, patients in our study required lower voltage and medication for satisfactory symptom control.</p>
