We read the article entitled “Cortical Venous Thrombosis – A Case Series and Review of Recent Updates” on the esteemed “Apollo Medicine” with great interest. Garg et al. reviewed the etiology, clinical features, diagnostic tools, and mainstay therapy of cortical venous thrombosis with recent advancements and reported a series of cases.[1]

Here, we would like to discuss more stroke-seeking behavior trends and other specialties such as movement disorder and epilepsy. Google is an important search engine, in which millions of people worldwide every day look for health-related information. In this context, the analysis of this database is important because it provides insight into the current trends and changes over time.[2]

We aimed to compare the number of search results and trends returned by Google for the terms of Parkinson's disease (PD), stroke, and seizure. Each of these disorders belongs to different clinical syndromes such as movement disorders, cerebrovascular diseases, and epilepsy. In addition, the prevalence of these diseases varies, with ischemic stroke being the fifth cause of death; in the United States, stroke is estimated to occur in more than 700,000 people every year.[3] In its turn, the cumulative lifetime incidence of seizure is about 4%.[4] However, PD affects only approximately 1 to 2 people/1000 at any time; the prevalence of this movement disorder increases with age to affect 1% of the population aged above 60 years.[5]

To evaluate how often people search the Google to look for online information related to PD, stroke, and seizure, we entered a set of keywords, namely “Parkinson,” “stroke,” and “seizure” at the “Google's” main page (available at http://www.google.com/, accessed on 11/19/2019). Moreover, to analyze the trends, we used the same keywords at the “Google Trends'” main page, which was selected worldwide in a period of 1 year (available at https://trends.google.com/, accessed on 11/19/2019).

The numbers found were in decrescent order as follows: stroke 729,000,000; seizure 208,000,000; and PD 135,000,000. These results are in accordance with the incidence of the diseases in the general population. We summarize the information of Google Trends in [Figure 1], in which the numbers represent the search interest relative to the highest point on the chart for the given region and time, where higher values are associated with higher popularity of the term.[6] Stroke was the most interest-based term among the three during the last year, but it is intriguing the second place most of the time being PD. Therefore, the term “Parkinson's disease” is more searchable than seizure, but the incidence and number of information about seizure are higher in the Google database.
