Because the brain can shift slightly during surgery, the electrodes can become displaced or dislodged from the specific location. This may cause more profound complications such as [[personality]] changes, but electrode misplacement is relatively easy to identify using [[CT scan]]. Also, complications of surgery may occur, such as bleeding within the brain. After surgery, swelling of the brain tissue, mild disorientation, and sleepiness are normal. After 2–4 weeks, a follow-up visit is used to remove [[Surgical suture|sutures]], turn on the neurostimulator, and program it.{{citation needed|date=November 2013}}

因为在手术过程中大脑可能会轻微移动，电极可能会从特定位置移位或移位。这可能会导致更深刻的并发症，如个性的改变，但电极错位是相对容易识别使用 CT 扫描。此外，手术并发症也可能发生，如脑出血。手术后，脑组织肿胀，轻度迷失方向和嗜睡是正常的。2-4周后，随访取出缝线，打开神经刺激器，并对其进行编程。
