A lead for deep brain stimulation includes a first electrode group and a second electrode group. The first electrode group includes at least one first electrode which is adapted for being positioned in a nucleus accumben of a brain. The second electrode group includes at least one second electrode which is adapted for being positioned in an anterior limb of an internal capsule of the brain. With one single lead implanted in the brain, the first electrode group and the second electrode group simultaneously stimulating the nucleus accumben and the anterior limb of the internal capsule, and the present disclosure improves the effect and safety of DBS in the therapy of drug-addiction, OCD and/or depression.
