If you’ve had a serious blow to your skull or scalp you should seek medical attention immediately, because there’s a risk of bleeding and blood clots, which could lead to permanent brain damage.
Head injury is a leading cause of death and disability and knowing when an injury could be serious, will enable you to get help sooner.
A head injury is a general term used to describe any injury to the skull, scalp or brain. It’s usually caused by a sudden impact or jolt to the head.
Signs and symptoms of a head injury can be subtle and difficult to identify.
If the head was caused by a forceful blow to the head at speed you should call an ambulance, regardless of any other symptoms.
If you or someone you know has become unconscious or unresponsive as a result of a head injury, this is another reason to get medical help immediately.
Another warning sign is when a person experiences concussion, showing signs of memory loss, dizziness, confusion, blurred or double vision or trouble balancing or staying awake.
Fits or seizures also suggest a serious injury, as well as changes in mood (like becoming more irritable), continuous vomiting and swelling or bruising around the eyes or behind the ears.
At the hospital, doctors will ask a series of questions and are likely to take a CT scan to see the extent of your injury and provide a diagnosis.
A serious head injury can cause bleeding, blood clots or a build-up of fluid in the brain. This can then put pressure on the brain and lead to temporary or permanent brain damage.
If your skull has been fractured, this could lead to an infection as bacteria can enter through any skin that’s been broken.
If left untreated, a serious head injury can also cause impaired consciousness, where a person is less aware or conscious, for example if they are in a coma or vegetative state.
Sometimes head injury symptoms may not be noticeable at the time of an injury. Symptoms usually start within 24 hours but they may take up to 3 weeks to appear.
If you’re at all worried about a head injury get it checked by a doctor. They should be able to tell you whether it’s serious or refer you for further tests.
