Symptoms of PD

Parkinson's disease (PD) includes motor and non-motor symptoms.

Motor Symptoms

The four cardinal motor symptoms are:

  • bradykinesia:  slow movement
  • rigidity:  stiffness of the arms, legs, or neck
  • tremor
  • postural instability:  balance issues  

One must have two of the four cardinal symptoms to have a diagnosis of Parkinson's disease. 

Other motor symptoms (that are related to the cardinal four) include:

  • walking or gait difficulty:   freezing of gait, festination or shuffling, lack of arm swing
  • dystonia
  • speech problems:  such as hypophonia or soft voice
  • swallowing issues:  also called dysphagia

Our "Overview of PD" page contains links to good general overviews of these motor symptoms.  Plus our "Speech and Swallowing" page contains links to good resources on speech and swallowing dysfunction.

 

Non-Motor Symptoms

Although PD is classified as a movement disorder, the non-motor symptoms of PD are numerous.  Some common non-motor symptoms are:

 

Our "Non-Motor Symptoms in PD" page contains links to good general overviews of these non-motor symptoms.  Plus we have webpages on the specific non-motor symptoms listed above.
