Notes from the Nurse's Office


The brain is made up of soft tissue and is cushioned by blood and spinal fluid.  When someone gets a blow to the head or his/her head hits something very hard, the brain suddenly shifts inside the skull and can knock against the skulls bony surface.  A concussion is a temporary change in the way the brain works when it is suddenly moved or jarred in this way.

Concussions can last a few moments or a person may be unconscious (knocked out or passed out) for a couple of minutes or longer.

Signs of concussion and/or head injury include:

  • Severe headache
  • Excessive drowsiness
  • Nausea and vomiting
  • Double vision, or pupils of different sizes
  • Loss of muscle coordination, such as walking strangely, or staggering
  • Any unusual behaviour such as confusion, irregular breathing, or dizziness
  • Bleeding or discharge from the ears

Can concussions be prevented?

Injuries happen.  But the best way to prevent a concussion is to take care of your head.

  • Always wear a seatbelt in a car.
  • When walking across the street, always look both ways and obey all street lights and traffic signs. 
  • Always use a crosswalk.
  • Wear helmets or headgear and other safety equipment when riding a bike, riding motorized bikes or vehicles skateboarding, riding a scooter and playing contact sports.

If you use your head, you can protect your head!
