    The cardinal signs of PD are the primary motor symptoms:

    • Shaking or tremor
    • Slowness of movement, called_bradykinesia
    • Stiffness or rigidity of the arms, legs or trunk
    • Trouble with balance and possible falls, also called postural instability

    It is important to know that there are many other possible symptoms that are called secondary motor symptoms and nonmotor symptoms. In the past, it was generally thought that the primary motor symptoms are the most troubling for PD patients. However, in recent years it has been recognized that for many patients, nonmotor symptoms such as cognition issues, fatigue, constipation, and sleep problems can be the most troubling.

    There are four primary motor symptoms of PD: tremor, rigidity, postural instability, and bradykinesia (gradual loss and slowing down of spontaneous movement). These four symptoms are considered the key characteristics of the disease but there are many other secondary and non-motor symptoms that affect people with PD.
