Why minor head injuries can be serious

A head injury may look minor from the outside but it can sometimes cause serious problems inside the brain. Health experts have highlighted several warning signs that people should never ignore after a head injury.

A head injury can happen because of a fall a road accident, a sports injury or a blow from a hard object. Even if a person feels fine immediately after the incident, it is important to watch for any unusual symptoms.

Experts warn that some signs of a serious brain injury may not appear straight away. In some cases, symptoms can develop several hours or even days after the injury.

Unusual Sleepiness or confusion

According to Indian neurosurgeon Dr Nitin Bhakal, mild tiredness or slight sleepiness after a head injury is not always a sign of danger.

However certain changes in a person’s condition require immediate medical attention.

These include difficulty waking the person unusual weakness or tiredness, confusion during conversations and noticeable changes in behaviour.

Such symptoms may indicate a concussion, which occurs when a blow or sudden movement affects the brain. In more serious cases, they could also be signs of bleeding inside the skull.

Children need special attention after a head injury.

If a child vomits following a blow to the head, seek medical advice promptly, especially if vomiting continues or other symptoms appear.

Severe headache or loss of consciousness

Some symptoms require immediate medical attention. These include

A severe or worsening headache

•Repeated vomiting

•Seizures

•Loss of consciousness

•Extreme sleepiness or difficulty waking up

•Trouble speaking or walking

•Weakness in any part of the body

•Unusual confusion

•One pupil becoming larger than the other

•Clear watery fluid coming from the nose or ears

These symptoms may indicate a serious brain injury.  If any of them occur after a head injury seek emergency medical care immediately.

Why monitoring is important

A person’s condition can change after a head injury, even if there are no serious symptoms at first. For this reason, close observation is important particularly during the first 24 hours.

If possible a responsible adult should stay with the injured person and watch for any changes in their condition. Do not delay medical care if new or worsening symptoms appear.

Is it safe to sleep after a head injury?

Sleeping after a head injury is not always dangerous.  However unusual drowsiness, difficulty waking up or a reduced level of consciousness can be signs of a serious problem.

If the injury appears significant or any warning signs develop seek medical help rather than assuming the person simply needs rest.

Depending on the symptoms, a doctor may perform a neurological examination or recommend a CT scan or other tests to check for damage inside the skull.

Final tips

A head injury should never be judged only by how serious it looks from the outside. Some dangerous symptoms can develop hours or days later.
