Study Estimates CTE Among Nearly 3 in 4 Former NFL Players
A new study estimates that nearly 3 in 4 former NFL players had CTE, a trending topic in the San Francisco-Oakland-San Jose area.

San Francisco Oakland San Jose, CA, October 28, 2026 —
A new study estimates that nearly three in four former National Football League players had CTE, according to a trend summary that also identifies the subject as a trending topic in the San Francisco-Oakland-San Jose area.
The summary does not provide the study’s title, publication date, authors, sample size or methodology. It also does not explain how the researchers determined the estimate or specify which former players were included. Those details are not available in the information provided, so the estimate cannot be examined further here.
The summary does not expand the acronym CTE or describe the study’s findings beyond the estimate. It also gives no information about whether the researchers reported limitations, compared results across groups or drew conclusions beyond the figure. No additional findings or explanations are provided.
The San Francisco-Oakland-San Jose area is identified as a place where the topic is trending; the summary does not say that the study was conducted there or that the estimate is specific to former players from the region. It also does not provide a date or platform for the reported trend.
The central reported finding is therefore limited to the study’s estimate: nearly three in four former NFL players had CTE. Further details about the research and its context were not included in the summary.
