Parkinson's disease is characterized by four cardinal motor symptoms: postural instability, bradykinesia (slowed movements), tremor, and rigidity. Bradykinesia is known for slowness of movement and can make daily tasks more challenging. Rigidity means stiffness of muscles, which can lead to limitation and discomfort in movement. Postural instability means maintaining a balance that causes falls. Tremor is mostly known as "pill-rolling," which generally happens at rest and affects the jaw, tongue, face, and limbs.

Additionally, these motor symptoms, such as Parkinson's disease, can be present with non-motor symptoms like anxiety, depression, cognitive decline, and sleep abnormalities.
