Parkinson’s disease (PD) is called a movement disorder because of the tremors, slowing and stiffening movements it can cause, and these are the most obvious symptoms of the disease. However, Parkinson’s affects many systems in the body. Its symptoms are different from person to person and usually develop slowly over time.
Primary Movement Symptoms
There is no single test or scan for Parkinson’s, but there are three telltale symptoms that help doctors make a diagnosis:
- Bradykinesia (slowness of movement)
Bradykinesia plus either tremor or rigidity must be present for a PD diagnosis to be considered.
Another movement symptom, postural instability (trouble with balance and falls), is often mentioned as a primary symptom, but it does not occur until later in the disease progression. In fact, problems with walking, balance and turning around early in the disease are likely a sign of an atypical parkinsonism. Though each person's path with PD is unique, active engagement in exercise and wellness is central to maintaining balance and movement for everyone who lives with PD.
Slowness, stiffness and shakiness can impact daily living. Exercise is proven to ease these and other PD symptoms and can slow disease progression. Verified exercise strategies can keep you moving well. A physical therapist with Parkinson’s expertise can help you get started.
What causes Parkinson’s movement symptoms?
Dopamine is a chemical messenger (neurotransmitter) that is primarily responsible for controlling movement, emotional responses and the ability to feel pleasure and pain. In people with Parkinson’s, the cells that make dopamine are impaired. As Parkinson’s progresses, more dopamine-producing brain cells die. Your brain eventually reaches a point where it stops producing dopamine in any significant amount. This causes increasing problems with movement.

Exercise — and tools such as PD Health @ Home Fitness Fridays — can minimize movement symptoms. In fact, exercise is as important to living well with Parkinson’s as medications and other therapies. Find an activity you love and work with your doctor to create a plan to stay well.
