A concussion can arise from the brain moving either rapidly back and forth or banging against the side of the skull, generally associated with an accident or sports injury. This sudden movement can stretch and damage brain tissue and trigger a chain of harmful changes within the brain that interfere with normal brain activities. Common symptoms include nausea, headache, confusion, dizziness and memory problems. No two concussion injuries are the same. Our physiotherapists are trained to assess, treat and manage concussion symptoms.
