More than one million Americans are living with Parkinson's disease, but scientists say new breakthroughs in treatments, including deep brain stimulation, dopamine therapies, focused ultrasound, and stem-cell replacement, are bringing real hope and the potential to slow or even stop the progression of the disease.

Why it matters

Parkinson's disease is a debilitating neurological disorder that affects millions, and these new treatments could dramatically improve quality of life and long-term outcomes for patients. The research represents significant progress in the fight against this challenging disease.

The details

Researchers at Vanderbilt University Medical Center are studying deep brain stimulation (DBS), a medical device implanted in the brain that sends electrical pulses to control movement. A new study found DBS may actually slow or stop the progression of motor symptoms in some patients. Additionally, new dopamine therapies, focused ultrasound treatments, and stem-cell replacement therapies are all showing promise in providing more precise, long-lasting relief and potentially modifying the course of the disease.

  • In 2026, more than 1 million Americans are living with Parkinson's disease.
  • Another 90,000 people are expected to be diagnosed with Parkinson's this year.

What they’re saying

“At the time I was diagnosed, I did some research online and came up with the accepted life expectancy for someone with Parkinson's was 10 years.”

— Steve Purcell (Ivanhoe Newswire)

“A medical device that's implanted in the brain in people with Parkinson's disease, two electrodes, which are about the thickness of an angel hair pasta noodle, are implanted in each side of the brain.”

— David Charles, MD, Professor & Vice-Chair of Neurology, Vanderbilt University Medical Center (Ivanhoe Newswire)

“About a third of the people that received deep brain stimulation, in fact, did have their motor symptoms stop progressing over a course of two years. And in Parkinson's disease, that should never happen.”

— David Charles, MD, Professor & Vice-Chair of Neurology, Vanderbilt University Medical Center (Ivanhoe Newswire)

“It's just not something to get a diagnosis of and lose hope.”

— Steve Purcell (Ivanhoe Newswire)

What’s next

Researchers at Vanderbilt University Medical Center plan to continue studying the long-term effects of deep brain stimulation and other emerging treatments to further understand their potential to slow or stop the progression of Parkinson's disease.

The takeaway

The new breakthroughs in Parkinson's research, from advanced surgical options to next-generation medications and cell-based therapies, are offering renewed hope for patients and their families. These developments represent significant progress in the fight against this debilitating neurological disorder.
