Parkinson's disease is a degenerative neurological disease, and its incidence is increasing. Research in animals suggests that moderate- to high-intensity exercise can slow the disease's progression, says Amy DeBlois, a doctor of physical therapy and member of the faculty of Upstate's department of physical therapy education. She explains the motor symptoms (such as tremors, balance problems or stiffness) and non-motor symptoms (such as changes in smell, sleep patterns and memory) a person may have before being diagnosed with Parkinson's and how physical therapists can help. "We want to see them as soon as the diagnosis is made," she says. Click here for more information on the disease.
