Prevalence estimates of anger range as high as 71%, and aggression can be seen is as many as 11-34% of patients following a traumatic brain injury (TBI). Classic expressions of anger include:
  • Yelling
  • Cursing
  • Throwing objects
  • Punching walls
  • Slamming doors
  • Threats
Although there is no consistent relationship between injury severity and anger expression, individuals with a pre-TBI history of anger issues may experience exacerbations of these pre-existing difficulties. However, anger may also be seen as a new manifestation even without prior history of anger problems. Such anger may also escalate into physical aggression in some cases.
