Deep brain stimulation (DBS) is a surgical procedure involving the implantation of a device in the brain to deliver targeted electrical stimulation. It effectively treats movement disorders like Parkinson's disease and dystonia, with ongoing exploration for mental health conditions such as depression and obsessive-compulsive disorders.
However, the current reliance on doctors for implementing and adjusting stimulation parameters limits its efficiency. A recent commentary in Nature Reviews Neurology highlights the potential of artificial intelligence (AI) to enhance deep brain stimulation outcomes.
Researchers are investigating two main areas where AI can contribute to deep brain stimulation. The first area focuses on target localisation, using AI to identify optimal electrode placement by precisely identifying anatomical landmarks through advanced medical imaging techniques like magnetic resonance imaging (MRI). This research aims to improve precision in electrode implantations by better identifying small anatomical targets.
AI is also being utilised to enhance medical imaging methods such as MRI itself, benefiting not only deep brain stimulation but also various applications in neurology and neuroscience.
The second area explores the use of AI in selecting electrical stimulation parameters. Traditional methods rely on time-consuming manual programming by skilled professionals. Researchers are exploring automated or partially automated programming using AI, which incorporates imaging, electrophysiology, and clinical data to provide a more efficient alternative. Machine learning models trained on functional MRI data have shown promise in predicting optimal stimulation parameters for different patients.
While ongoing research and development are necessary, the integration of deep brain stimulation with AI holds the potential to revolutionise the field. It aims to improve the precision, efficiency, and personalisation of treatment, ultimately enhancing the quality of life for patients and their families.
