More effective treatments on the horizon for Parkinson's patients

Parkinson's disease affects about six million people worldwide and does not have a cure.

Still, researchers are learning more and more about the disease every day.

Now, an old drug may offer patients new hope.

Dr. David Higgins lives a busy and active life but, a few years ago, some mysterious symptoms threatened to slow him down.

"I was having trouble swimming and I was having trouble running, says Higgins. Stiffness, soreness, lack of control."

David was diagnosed with Parkinsons, a disease that affects movement.

"It does not make me feel good about the future, says Higgins.

However, neurologist Irene Litvan says the future is looking brighter for people like Higgins.

Litvan is studying a new therapy for Parkinsons that is already being used to treat high blood pressure.

The good thing is that multiple people have taken it, says Litvan.
