What condition was Deep Brain Stimulation (DBS) originally developed to treat?

Deep Brain Stimulation (DBS) was originally developed to treat Parkinson's disease, a neurological disorder characterized by motor symptoms such as tremors, rigidity, and bradykinesia (slowness of movement). This therapy involves implanting electrodes in specific areas of the brain, which can help modulate the neuronal activity that leads to these symptoms.

The use of DBS in Parkinson's disease has been shown to significantly improve motor function and quality of life for patients, particularly when other treatments, such as medication, become less effective over time. While DBS is also investigated for other conditions like depression, OCD, and PTSD, it was specifically conceived to address the debilitating motor symptoms associated with Parkinson's disease, making it the first and primary indication for this intervention.
