Symptom types

The symptoms of Parkinson’s disease (PD) can vary from person to person, but the main (core or cardinal) movement-related symptoms are:

• slowness of movement (also called bradykinesia)
• stiffness (rigidity)
• tremor
• loss of balance (postural instability)

As well as these four main symptoms, PD can produce other symptoms that are not related to movement, known as ‘non-motor’ symptoms. Treatment of both the motor and non-motor symptoms is vital for the successful management of PD.
