Impact of World Cerebral Palsy Day on Public Interest in Brazil: Evidence from Internet Search Data.

Aim: This study investigated the impact of the World Cerebral Palsy Day (WCPD) campaign on the public interest using Google Trends Analysis data in Brazil.

Methods: Google Trends was used to collect Relative Search Volume (RSV) data for "cerebral palsy" from 2004 to 2011 (control years) and 2012 to 2022 (WCPD years). RSV during the 4 weeks around WCPD (period of interest) was compared with the rest of the year (control period) in each timeframe.
