Head injuries range from a minor knock to a life-threatening emergency, and the difference is not always obvious in the first few minutes. Road accidents and falls are the most common causes. Knowing which signs matter helps families act quickly when it counts.
Why the first hours matter
Some of the most dangerous consequences of head injury — particularly bleeding inside the skull — can develop over hours rather than instantly. A person may seem fine immediately after an accident and deteriorate later. This is precisely why observation after a significant head injury is taken seriously, and why access to a neurosurgeon at any hour matters.
Warning signs to watch for
After any significant blow to the head, watch closely for the following over the next 24–48 hours:
- Loss of consciousness, however brief
- A headache that steadily worsens rather than settling
- Repeated vomiting
- Increasing drowsiness, or difficulty waking the person
- Confusion, unusual behaviour or difficulty recognising people
- Weakness, numbness or clumsiness in an arm or leg
- Slurred speech or blurred/double vision
- Clear fluid or blood coming from the nose or ear
- A seizure
What to do at the scene
- Call for help immediately if any warning sign above is present
- Do not move someone with a suspected neck or spine injury unless they are in danger
- Keep the person still, and do not leave them alone
- Do not give food, drink or painkillers until they have been assessed
- Note the time of injury and what happened — this genuinely helps the treating team
Assessment and treatment
In hospital, assessment involves a neurological examination and usually a CT scan of the head. Many head injuries need observation rather than an operation. Where there is significant bleeding or pressure on the brain, urgent surgery may be required — and advanced ICU support afterwards is often as important as the surgery itself.
