Parkinson’s Disease Symptoms & Signs

Signs of Parkinson’s disease include motor and no-motor symptoms. Each person with Parkinson's experiences the disease differently. While tremors are a common primary symptom not all people with PD have tremors. Additional, symptoms and disease progress at different rates between individuals.

Primary Symptoms of Parkinson’s

Tremor – Tremors occur in about 70% of those living with Parkinson’s. At first, the tremor appears on one side of the body in the hand or foot while relaxed or at rest.

Slowness of Movement (Bradykinesia) – Individuals with Parkinson’s disease may experience a change in spontaneous movement that causes a person with Parkinson’s to respond slowly and often lack facial expressions (masked face).

Rigidity – Muscles may fail to relax like normal muscles causing the individual to appear rigid and have a decreased range of motion. Rigidity may be painful.

Postural Instability – Loss of some reflexes needed to maintain a normal posture may cause individuals to be unstable when standing upright. Postural instability increases the likelihood of falling.

Secondary motor symptoms include:

  • Problems with speech and voice
  • Incontinence
  • Difficulty swallowing
  • Freezing

Non-motor symptoms of PD include:

  • Excessive sweating – especially of hands and feet
  • Constipation
  • Dry skin
  • Mood changes – anxiety and depression
  • Cognitive changes
  • Sleep disturbances
  • Hyper sexuality or low sex drive
  • Frequent urination and incontinence

The symptoms someone has and how quickly the condition develops will differ from one person to the next. Always consult your doctor to determine if the symptoms you’re experiencing may be a sign of Parkinson’s disease or a sign of other health issues.
