Common Signs of a Head Injury
When to Seek Emergency Medical Attention
Call 911 or go to the emergency room right away after a head injury if there is any loss of consciousness, even for a few seconds. You should also seek emergency care for a headache that keeps getting worse, repeated vomiting, seizures, slurred speech, one pupil larger than the other, weakness or numbness in the arms or legs, extreme drowsiness, trouble waking the person up, severe confusion, agitation, or clear fluid or blood draining from the nose or ears. A visible deformity or soft spot on the skull also requires immediate medical attention.
Seeing blood or another obvious injury
Blood or clear fluid coming from the nose or ears after a head impact can be a serious warning sign and should be treated as an emergency.
Another sign can be confusion
Some people also feel mentally foggy, have trouble concentrating, or cannot remember the events right before or right after the injury. Severe confusion, unusual agitation, or an inability to recognize people or places are red flags that require immediate care.
Dizziness can also be cause for concern
Balance problems, blurred vision, and sensitivity to noise can also appear after a concussion and should not be ignored.
Double Vision
Vision changes can also include blurred vision. If one pupil becomes larger than the other, this is a medical emergency.
Headaches
A headache that gets worse instead of better should be evaluated right away. Repeated vomiting, rather than a single isolated episode, is another important warning sign after a head injury.
Other Concussion Symptoms to Watch For
Not every head injury causes dramatic symptoms right away. Some concussion symptoms are more subtle but still deserve medical attention. These can include sleeping much more or less than usual, trouble falling asleep, irritability, sadness, mood swings, and ongoing trouble with focus or memory.
Signs in Infants and Young Children
Young children may not be able to explain how they feel after a head injury, so parents should watch for warning signs such as inconsolable crying, unusual fussiness, refusing to eat or nurse, loss of interest in favorite toys or activities, or changes in walking and coordination. These symptoms should prompt a medical evaluation.
