Head Injury First Aid: What to Do — and When It's an Emergency

Head injuries range from a minor bump to a life-threatening emergency, and the tricky part is that a person can seem fine at first and deteriorate hours later. Knowing the danger signs — and what to do in the first few minutes — can save a life. This is general first-aid guidance; when in doubt, always get medical help.

First aid in the first few minutes

• Keep calm and keep them still. If there was a fall or a high-impact hit, assume the neck may be injured — avoid moving or bending it unless there is danger where they are.
• Check response and breathing. If unresponsive and not breathing normally, call for emergency help and begin CPR if you are trained.
• Control bleeding by pressing a clean cloth gently around — not directly into — any wound. Scalp wounds can bleed a lot even when minor.
• Apply a cold pack wrapped in cloth to a bump to reduce swelling.
• Do not let them drive. Someone else should take them to hospital, or call an ambulance.

Danger signs — go to hospital now

Take the person to an emergency department (or call an ambulance) if any of these appear, whether immediately or in the hours and days after the injury:

• Loss of consciousness, even briefly, or difficulty staying awake.
• Increasing drowsiness, confusion, or unusual behaviour.
• Repeated vomiting.
• A severe or worsening headache.
• A fit or seizure.
• Weakness, numbness, slurred speech, or difficulty walking.
• Unequal pupils, double or blurred vision.
• Clear fluid or blood leaking from the nose or ear.
• A deep cut, a dent in the skull, or a wound that won't stop bleeding.

What not to do

• Don't move the neck unnecessarily if a spinal injury is possible.
• Don't give food, drink or medicines (other than as advised) until serious injury is ruled out.
• Don't leave the person alone in the first 24 hours after anything more than a trivial knock.
• Don't apply pressure directly onto a wound if the skull may be dented or fractured underneath.
• Don't assume “they seem fine” means safe — some bleeds show up hours later.

Concussion and the “talk and deteriorate” trap

A concussion is a temporary disturbance of brain function after a knock — headache, dizziness, feeling dazed, nausea or trouble concentrating. Most people recover with rest. The important warning is the “talk and deteriorate” pattern: a person who is conscious and talking soon after injury but then becomes drowsy or confused may have a slow bleed pressing on the brain. That is an emergency and needs an urgent CT scan.

When is a CT scan needed?

Not every head injury needs a scan. A CT of the head is usually advised when there has been loss of consciousness, repeated vomiting, a seizure, worsening drowsiness or confusion, a suspected skull fracture, any focal weakness or speech problem, or a dangerous mechanism such as a high-speed accident or fall from height. The treating doctor decides based on the exact circumstances — when advised, don't skip it.

Extra caution for some people

• On blood thinners (such as warfarin or similar): even a modest head injury can bleed more, so seek assessment promptly.
• Older adults: bleeds can develop with less force and sometimes days later — keep a closer watch.
• Young children: watch for persistent crying, refusal to feed, drowsiness or repeated vomiting, and have any significant fall checked.

Monitoring after a minor head injury at home

If a doctor has assessed a minor injury and advised home care, someone should stay with the person for 24 hours. Rest, simple pain relief if advised, and gentle observation are usually enough. Return to hospital at once if any danger sign above appears. It is always safer to be checked twice than to miss a bleed once.

Head injuries are unpredictable, but early action makes a real difference. If you are worried about someone after a head injury in Indore, seek emergency care without delay — timely assessment and, when needed, a scan are what protect the brain.
