Parkinson's disease: Causes and incidence
(Professional Guide to Diseases (Eighth Edition))

Although the cause of Parkinson’s disease is unknown, study of the extrapyramidal brain nuclei (corpus striatum, globus pallidus, and substantia nigra) has established that a dopamine deficiency prevents affected brain cells from performing their normal inhibitory function within the central nervous system. Parkinson’s disease occurs in families in some cases; in others, it’s secondary to external factors such as medications used to treat schizophrenia.

Parkinson’s disease, also called parkinsonism, paralysis agitans, and shaking palsy, is one of the most common crippling diseases in the United States. Parkinson’s disease strikes 2 in every 1,000 people, most often developing in those older than age 50; however, it also occurs in children and young adults. Because of increased longevity, this amounts to roughly 60,000 new cases diagnosed annually in the United States alone. Incidence increases in persons with repeated brain injury, including professional athletes, and persons using psychoactive substances, whether prescribed or illicit.

About prevalence and incidence statistics:

The term 'prevalence' of Parkinson's Disease usually refers to the estimated population of people who are managing Parkinson's Disease at any given time. The term 'incidence' of Parkinson's Disease refers to the annual diagnosis rate, or the number of new cases of Parkinson's Disease diagnosed each year. Hence, these two statistics types can differ: a short-lived disease like flu can have high annual incidence but low prevalence, but a life-long disease like diabetes has a low annual incidence but high prevalence. For more information see about prevalence and incidence statistics.
