Sometimes brain injuries are not obvious. An injury such as a concussion, stroke, or whiplash can cause brain damage without showing evidence of serious trauma. The following is a list of common TBI symptoms that victims of brain injury may manifest:

  • Persistent mild headaches
  • Poor memory
  • Poor concentration
  • Poor organizational ability
  • Poor decision making
  • Slow speech
  • Slow reading
  • Confusion
  • Neck pain
  • Lack of energy
  • Change in sleep patterns, such as insomnia or oversleeping
  • Loss of balance or coordination
  • Sensitivity to light
  • Blurred vision
  • Loss of senses
  • Ringing in the ears
  • Loss of sex drive
  • Mood changes


Noticing signs of brain injury in children may be more difficult because they have less developed communication skills. The child may feel some symptoms but cannot express them. If you observe any of the following changes in your child, a brain injury is possible:

  • A lack of energy
  • Crankiness or an increase in temper tantrums
  • Changes in their eating habits
  • Changes in the way they play
  • Altered performance in school
  • Loss of interest in favorite toys
  • Loss of skills, such as toilet training, reading, or writing
  • Loss of coordination and balance
