Bilateral thalamic deep brain stimulation for essential tremor in elderly patients

Area of Science:

• Neurology
• Neurosurgery

Background:

• Essential tremor (ET) is a common neurological disorder.
• Thalamic deep brain stimulation (DBS) is an established treatment for refractory ET.

Purpose of the Study:

• To evaluate the influence of age on the efficacy and safety of thalamic DBS in essential tremor patients.
• To compare clinical outcomes between younger (<70 years) and older (≥70 years) ET patients undergoing thalamic DBS.

Main Methods:

• A prospective study of 26 consecutive essential tremor patients receiving thalamic DBS.
• Standardized assessments for tremor, cognition, and mood were used.
• Patients were followed for 2 years, with age groups <70 and ≥70 years compared.

Main Results:

• No significant differences in tremor control, cognitive function, or mood were observed between the age groups.
• Adverse events were comparable between younger and older patients.
• Clinical outcomes remained consistent across different age demographics.

Conclusions:

• Thalamic deep brain stimulation (DBS) is a safe and effective treatment for essential tremor (ET).
• The efficacy and safety of thalamic DBS for ET are independent of patient age.
• Age should not be a limiting factor when considering thalamic DBS for essential tremor.
