Therapy
Deep Brain Stimulation
Deep brain stimulation implants electrodes in the brain that send electrical signals to reduce symptoms of conditions such as Parkinson’s disease.
Quick answer
Deep Brain Stimulation: what it is, why it's done and what happens
Deep brain stimulation (DBS) places fine electrodes into specific areas of the brain, connected to a pacemaker-like device under the skin of the chest, which delivers electrical impulses to modify abnormal brain activity.
- Why it is done: It is used mainly for Parkinson’s disease, essential tremor and dystonia, when symptoms such as tremor, stiffness or abnormal movements are not well controlled by medicines, and for some other conditions.
- What happens: The electrodes are placed through small holes in the skull, sometimes with the person awake to help target the correct area, and connected to the implanted device.
What it is
Deep brain stimulation (DBS) places fine electrodes into specific areas of the brain, connected to a pacemaker-like device under the skin of the chest, which delivers electrical impulses to modify abnormal brain activity.
Why it is done
It is used mainly for Parkinson’s disease, essential tremor and dystonia, when symptoms such as tremor, stiffness or abnormal movements are not well controlled by medicines, and for some other conditions.
What happens
The electrodes are placed through small holes in the skull, sometimes with the person awake to help target the correct area, and connected to the implanted device. It is often done in stages.
Recovery
The device is switched on and adjusted over the following weeks. Fine-tuning the settings to balance benefit and side effects takes time. Medicines are often reduced as symptoms improve.
Good to know
Risks and things to consider
Risks include bleeding, infection, and stimulation side effects such as speech or mood changes, which can often be adjusted. DBS controls symptoms but does not cure the underlying condition.

Answers
Deep Brain Stimulation: frequently asked questions
Does deep brain stimulation cure Parkinson’s disease?
No. It can significantly reduce symptoms such as tremor and stiffness and improve quality of life, but it does not cure or stop the progression of the underlying condition.
Am I awake during the procedure?
Sometimes part of the surgery is done awake so the team can check the effect on your symptoms and place the electrodes accurately, though techniques vary and some are done fully asleep.
