The patient is placed under general anesthesia, and a small burr hole is made in the skull to access the target area in the brain. Using advanced imaging techniques, the surgeon precisely guides the lead, which is a thin wire with electrodes, to the specific brain region that will be stimulated. The lead is then secured in place and connected to an implanted pulse generator, which is similar to a pacemaker. This generator is typically placed under the skin in the chest or abdomen. After the surgery, the patient may experience some soreness at the incision site, but this discomfort is typically manageable with pain medication.
Managing Risks and Potential Side Effects of Deep Brain Stimulation for Treatment-Resistant Depression
Deep brain stimulation (DBS) has emerged as a promising treatment option for individuals with treatment-resistant depression (TRD). However, like any medical intervention, it is essential to be aware of the potential risks and side effects associated with this procedure. Patients considering DBS should be well-informed and prepared for the possibilities that may arise during and after the treatment.
