Hypothesis
Is subthalamic nucleus deep brain stimulation (DBS) as effective in elderly patients as in younger patients?
Conclusion
DBS of the STN is clinically as effective in elderly patients as it is in younger ones, but elderly patients have a higher risk of surgery-related complications.
Supporting Evidence
- ADL scores improved significantly in both age groups after DBS.
- Complications were more frequent in elderly patients, including higher rates of infections.
- Motor function improvement was observed in both age groups without significant differences.
Takeaway
Doctors can help older people with Parkinson's disease by using a special treatment called deep brain stimulation, which works just as well for them as it does for younger people.
Methodology
Bilateral electrode implantation into the subthalamic nucleus was performed in 73 patients, divided into two age groups, with assessments at preoperative and 6-month follow-up intervals for 24 months.
Potential Biases
Potential bias due to retrospective analysis and selection of patients.
Limitations
The study is retrospective and may not account for all variables affecting outcomes.
Participant Demographics
Patients aged 44 to 76 years, divided into two groups: <65 years (37 patients) and ≥65 years (36 patients).
Statistical Information
P-Value
p<0.05 for ADL scores and complication rates.
Statistical Significance
p<0.05
