b'Chapter hapterConcussionThe brain can move a little within the skull and it can be shaken by a blow to the head. A blow to one side of the head can cause injury to the opposite side of the head. This may cause concussion, which is a condition of widespread temporary disturbance of normal brain activity. Unconsciousness often follows a concussion injury but it is usually only brief. Concussion is the most common type of brain injury, but it is not normally associated with any lasting damage to the brain.Sports concussion has become a significant problem. In recent years, it has made headlines with reports about the consequences of returning to play too soon, as well as research findings into the long-term effects of the injury.A blow to one side of the head can cause injury to the opposite side of the brain.How to RecogniseBrief loss of consciousness.Dizziness.Nausea, vomiting.Blurred vision.Memory loss and a mild or generalised headache.Confusion, loss of short term memory.A mild case of concussion often quickly resolves, but medical advice should always be sought as soon as possible because serious signs and symptoms such as unrelieved headache, blurred vision, vomiting and altered conscious responses may develop much later. This could indicate the likelihood of a serious head injury such as fractured skull and/or cerebral compression.Not recognising concussion may result in serious consequences. All patients who have sustained a head injury, regardless of severity, are advised to seek assessment by a health care professional or at a hospital.The most important indicator of a head, neck and spinal injury is the history of the incident and the mechanism of injury.Head, Neck and Spinal Injury 91'
