Could acupuncture protect brain cells in Parkinson's disease?

What if a traditional therapy could slow the brain cell loss at the heart of Parkinson's disease? A fresh look at the science suggests acupuncture might do just that by influencing several forms of programmed cell death—the natural processes that go haywire and destroy dopamine-producing neurons in the condition. The review found that these cell death pathways are deeply interconnected through inflammation and cellular stress, and that acupuncture appears to have a beneficial effect on them. It's important to understand this is a review paper, not a new clinical trial. The authors are piecing together existing evidence to propose a biological story for how acupuncture might work. We don't have numbers on how much it might help people, what the side effects could be, or how it stacks up against other treatments. The finding is a promising clue about a potential mechanism, not proof of a cure.
