9. Prevalence and Epidemiology: The Numbers Behind the Conditions
Parkinson’s disease and Parkinsonism also differ in terms of prevalence and epidemiology. Parkinson’s disease is the most common movement disorder, affecting an estimated 1% of the population over the age of 60. The prevalence of Parkinson’s disease increases with age, and it is more common in men than in women.
On the other hand, Parkinsonism encompasses a wide range of conditions, with varying prevalence rates depending on the specific underlying cause. Secondary Parkinsonism, including drug-induced and toxin-induced forms, is less common than Parkinson’s disease. Atypical Parkinsonism associated with other neurodegenerative diseases is also relatively rare, with prevalence rates varying based on the specific condition.
Recognizing the differences in prevalence and epidemiology between Parkinson’s disease and Parkinsonism can help raise awareness of these conditions and inform public health strategies and research priorities. (9)
