Many different rehabilitation methods are used in order to reduce the occupational, physical and cognitive functional losses that occur after traumatic brain injury (TBI). Despite the research continuing for many years, a successful pharmacological treatment that will ensure recovery after TBI has still not been reported. Nowadays, with the increase in neurostimulation techniques and the understanding of brain electrical activity, treatment approaches to support functional improvement in TBI cases have started to appear in the literature. The aim of deep brain stimulation (DBS), which is currently used frequently in the surgical treatment of movement disorders, is to eliminate the symptoms that can only be treated inadequately through pharmacological methods by suppressing the abnormal stimuli arising in the electrical activity of the brain via electrodes placed in certain areas of the brain by stereotactic methods. Although there are some case-based studies in traumatic brain-damaged patients in recent years, the effect of deep brain stimulation has generally been studied in animal experiments, especially cerebrovascular infarction models, and promising results have been reported.
