Posterior subthalamic area stimulation for essential tremor: Long-term efficacy and the challenging balance of stimulation-related side effects

Key Points

• Sustained tremor reduction occurs with bilateral stimulation in essential tremor patients, indicating effectiveness long-term.
• Monitoring revealed notable stimulation-related side effects that require careful management and programming adjustments.
• Analysis of the data emphasizes the balance between efficacy and the presence of adverse stimulation effects over time.
• Long-term results support the need for ongoing assessments to optimize treatment while minimizing side effects.
