What is deep brain stimulation (DBS) primarily used for?

Deep brain stimulation (DBS) is primarily utilized for controlling tremors and movement disorders, particularly in conditions such as Parkinson's disease, essential tremor, and dystonia. The therapy involves implanting electrodes in specific areas of the brain that regulate motor function. These electrodes deliver electrical impulses that can alleviate symptoms by modulating abnormal brain activity.

In conditions like Parkinson's disease, patients often experience debilitating tremors, rigidity, and bradykinesia (slowness of movement). DBS works by targeting the basal ganglia, which plays a crucial role in the control of movement. When the electrical impulses from the electrodes are activated, they can improve motor function, reduce tremors, and enhance the overall quality of life for individuals with these movement disorders.

While other options like alleviating headaches, promoting sleep, or enhancing memory may involve various treatments or interventions, they are not the primary applications of deep brain stimulation.
