Parkinson’s disease is a chronic, progressive neurological disorder that primarily affects movement and coordination. It develops as nerve cells in the brain deteriorate, especially those that produce dopamine, a chemical critical for smooth, coordinated motion. This decline leads to hallmark symptoms such as tremors, muscle stiffness, slowed movement, and balance difficulties. As the disease progresses, many people also experience non motor symptoms like depression, sleep disturbances, and changes in speech and thinking.
At the Mayo Clinic, specialists emphasize that Parkinson’s is not the same for each individual. A diagnosis often involves careful medical history review, neurological exams, and sometimes imaging or genetic testing.
A Mayo Clinic neurologist, Dr. Eric Ahlskog, M.D., Ph.D., explains, “The focus of the Movement Disorders Clinic is to treat the symptoms of Parkinson’s disease, which we can do fairly well up to a point — not everything is perfectly responsive, but overall we do pretty well treating both the movement problems as well as some of the antecedent conditions that occur with it.”
Ongoing research at the Mayo Clinic aims to better understand genetic, environmental, and biological factors that contribute to Parkinson’s disease, improve early detection, and develop novel treatments to slow progression.
