The cause of Parkinson’s disease is unknown, however, research has shown that there are a number of attributing factors that may play a role in the disease’s development. Risk factors for Parkinson’s disease may include, but are not limited to:
- Age: Those that are aged 60 and older have a higher chance of developing PD than the general population.
- Gender: For unknown reasons, men are about one-and-a-half more likely to develop PD than women.
- Genetics: Though the risk is small, about 15 to 25 percent of those with PD report also having a relative with the disease.
- Head injuries: Those that have suffered head injuries in which they were knocked unconscious are at a greater risk of developing PD.
- Lewy bodies: Lewy bodies are irregular clumps of protein found in the brain stems of people with PD.
Encourage your parents to receive regular check-ups to screen for any signs of Parkinson's disease or other underlying conditions.
