Head injuries can range from mild (such as a bump on the head) to severe (such as a brain injury). Knowing the signs of a serious head injury is important in order to seek medical attention promptly. Here are some of the signs you should look out for:.

Loss of consciousness

If someone loses consciousness, it’s a sign of a serious head injury.

It’s normal to feel sleepy or dazed after a head injury, but if the person doesn’t wake up or is unconscious for more than a few minutes, go to the emergency room immediately.

Changes in pupils

If one of the pupils (the black part in the center of the eye) is larger than the other, or if they are of different sizes, it can indicate a serious head injury.

Other changes in pupils to watch out for include pupils that do not react to light or are slow to react.

Severe headache

A headache after a head injury is common, but if it is severe or getting worse, and is accompanied by other symptoms such as vomiting, confusion or seizures, it could be a sign of a serious injury to the brain.

Vomiting

Vomiting after a head injury can be a sign of a serious injury to the brain. If the person vomits more than once or shows signs of severe nausea, seek medical attention right away.

Seizures

A seizure is a sudden, uncontrolled electrical activity in the brain that can cause a variety of symptoms. Seizures after a head injury can indicate a serious injury to the brain.

If you witness a seizure or convulsion, call for emergency medical assistance.

Confusion or disorientation

If the person seems confused, disoriented, or is having trouble remembering things, it could be a sign of a serious head injury. Other signs to look for include slurring of speech, trouble walking, or getting lost even in familiar places.

Clear fluid or blood draining from the ears or nose

If the person has clear fluid or blood draining from their ears or nose, it’s a sign of a serious head injury. Fluid draining from the nose or ears can indicate a skull fracture, and blood can indicate an injury to the brain.

Loss of coordination

If the person is having trouble walking or moving, or seems unsteady on their feet, it could be a sign of a serious head injury. Loss of coordination is a common symptom of a brain injury.

Weakness or numbness in the extremities

If the person experiences weakness or numbness in their arms, legs, hands or feet, it could indicate a serious head injury. This can be a sign of damage to the brain stem, which controls nerve function throughout the body.

Mental changes

If the person is experiencing changes in their behavior or mood, such as agitation, irritability, or depression, it could be a sign of a serious head injury.

These changes can be caused by damage to the brain’s frontal lobe, which controls emotions and behavior.

Conclusion

A serious head injury can have devastating consequences, so it’s important to seek medical attention if you or someone you know shows any of the signs listed above. Do not hesitate to call for emergency assistance if the situation warrants it.
