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
- Postural Instability
- Impaired balance and/or Coordination
- 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.
