Study finds 96 percent of former NFL players had brain disease

The video discusses a study revealing that 87 out of 91 former NFL players tested had chronic traumatic encephalopathy (CTE), a brain disease linked to repetitive head trauma. CTE can be detected through brain scans but confirmed only after death. The disease progresses through stages, causing symptoms like rage, depression, confusion, memory loss, and eventually dementia. A $1 billion settlement was approved between the NFL and former players affected by CTE.
