Young Onset Parkinson’s Disease (YOPD) is defined by age of onset less than 40 years of age.  (Some authors use a looser definition of 50 years of age.)  Up to 10% of people with PD may be classified.  A higher percentage of young-onset patients have a genetic form of PD compared to older or typical age of onset patients.

Motor-Symptoms of Young Onset Parkinson’s Disease:

  • Tremor (hands, arms, legs, etc.)
  • Rigidity of limbs/trunk
  • Bradykinesia
  • Postural Instability
  • Impaired balance and/or Coordination

Non-Motor Symptoms

  • Depression
  • Changes in memory and thinking
  • Sleep disturbances
  • Constipation and/or urinary issues

How does Parkinson’s Disease Differ from Young Onset PD?

Patients diagnosed with YOPD typically have a more frequent family history of Parkinson’s Disease. This genetic component typically corresponds with a slower progression of PD symptoms, increased side effects to dopaminergic medications, and more frequent cases of dystonia.
