The role of heredity in late-onset Parkinson's disease ____.

Question

Quizplus · Accepted Answer

Heredity is known to play a greater role in early onset Parkinson's disease compared to late-onset Parkinson's disease. In fact, research suggests that only around 10% of cases of late-onset Parkinson's disease are caused by genetic factors, while the majority are believed to result from a combination of genetic and environmental factors. Therefore, option B is the correct choice. Option A is incorrect as heredity is not equally implicated in both forms of Parkinson's disease. Option C is incorrect as MZ twins have a higher concordance rate for Parkinson's disease compared to DZ twins, indicating a greater role of heredity in Parkinson's disease. Option D is incorrect as there is no evidence to suggest that heredity plays a greater role in Parkinson's disease in females compared to males.
