DBS is a surgery done for patients with Parkinson’s disease. The full form of DBS is Deep Brain Stimulation. It is helpful in patients whose symptoms are not well controlled with medications.
This is a brain surgery, but a relatively minor one.
A metal frame is usually attached to the patients head. A very small hole (approximately 1 cm in diameter) is made in the head, and a thin (1 to 1.5 mm thick) is inserted through it. The wire is pushed into a very particular part of the brain called the “sub-thalamic nucleus”.
The key part of the surgery is implanting thin wires into a small part of the brain called the “subthalamic nucleus”.
The same process is repeated on the other side and another small wire is inserted.
These wires are then connected to a small battery (a square of approx. 3 inch) that is kept in the skin below the chest. No part of this device can be seen from the outside, and any scars on the head are usually covered by hair in a few weeks.
None of the device parts are visible outside the body.
The device is usually turned on 4 weeks after the surgery. On average, most batteries last for about 5 years, and can be replaced when required.
