Deep Brain Stimulation (DBS) requires invasive, expensive surgery and doesn't deliver consistent or lasting outcomes because candidate selection is haphazard, and the procedure doesn't alter the disease trajectory. The dopaminergic cells in the striatum continue to die. That depends on the kind of Parkinson's. In some cases, the root cause is genetic, not neurodegenerative, and in those cases DBS can significantly alter the disease trajectory.
