What are the Symptoms of Concussion?


Some concussion symptoms may develop immediately.  Others, however, may be more subtle or may not be apparent until hours, day, or even longer after the concussion, such as when daily routines and associated demands are resumed.


The symptoms of a concussion may involve memory and cognition, judgment, attention, emotion and mood, and physical effects.


Such symptoms may include:

  • Confusion, disorientation, and appearing dazed or stunned
  • Memory loss (amnesia) that may or may not be associated with loss of consciousness, such as loss of memory of the impact
  • Headache
  • Nausea
  • Balance problems or dizziness
  • Blurred or double vision
  • Sensitivity to light and sound
  • Slurred speech
  • Behavioral or personality changes
