Potential indications for deep brain stimulation in neurological disorders: an evolving field

Area of Science:

• Neuromodulation
• Neurosurgery
• Neurology

Background:

• Deep brain stimulation (DBS) is an established therapy for movement and neuropsychiatric disorders.
• Its mechanisms are not fully understood but it is generally safe and well-tolerated.
• DBS is being explored for a wider range of neurological conditions.

Purpose of the Study:

• To review current data on the use of DBS for neurological disorders beyond accepted indications.
• To explore new DBS targets, challenges, and future directions.
• To summarize the level of evidence for these emerging applications.

Main Methods:

• A comprehensive literature search was conducted for DBS in neurological disorders (excluding accepted indications).
• Articles were individually analyzed for content, with redundant reports excluded.
• The level of evidence for each potential indication was summarized.

Main Results:

• Promising preliminary data exists for DBS in chronic pain, tinnitus, epilepsy, Tourette syndrome, Huntington's disease, tardive dyskinesia, and Alzheimer's disease.
• Initial results across diverse neurological disorders are encouraging.
• Larger, controlled, prospective trials are necessary to establish long-term safety and efficacy.

Conclusions:

• DBS shows potential for treating a variety of neurological conditions.
• Further rigorous clinical trials are essential to validate its safety and effectiveness.
• Advances in neuromodulation technology are continuously shaping DBS research and clinical practice.
