Letter to the Editor

Millions of people surf the Internet every day as a source of health care information looking for materials about symptoms, diagnosis, treatments and their possible adverse effects, or diagnostic procedures.

Since its launch in 2001, the free online encyclopedia Wikipedia has become the most popular general reference website, which contains approximately 30 million articles available in up to 287 languages and over 4.6 million English articles. With 18 billion page views and nearly 500 million unique visitors per month, the English version of Wikipedia ranks the fifth place in the list of the most visited websites, thus being very likely a common source of health care information by both patients and caregivers.

Worth of note, the first webpage that appears after entering the keyword “Parkinson’s disease” (PD) on Google, the most popular search engine worldwide, is the Wikipedia article on PD (’s_disease) (search conducted on 7 November 2014)....
