About three years before he retired, David Campbell noticed something weird happening as he typed. Whenever he tried to hit a letter, say "a," he'd get "aaa," like the keyboard was jamming or his finger was triple-tapping the key. That wasn't the only thing that seemed off—his sense of smell was faltering. "Little things," he says, "that I didn't think of as being a big deal."

Freezing is one of the most common and debilitating symptoms of Parkinson's disease, a neurodegenerative disorder that affects more than 9 million people worldwide. When individuals with Parkinson's disease freeze, they suddenly lose the ability to move their feet, often mid-stride, resulting in a series of staccato stutter steps that get shorter until the person stops altogether. These episodes a
