Indications of head injury among adults

Millions of individuals suffer from head injuries. Most cases of head injuries are not considered significant due to the bony structure of the head. Since the skull protects the fragile brain, a head injury usually involves cuts and bruises.

Head injuries are categorized as open and closed. When it comes to a closed head injury, the skull was not penetrated. As for an open injury, an object damaged the skull and penetrated the brain. Depending on the type of head injury, there are various types of symptoms that can occur. Once any symptoms manifest after an individual sustains an injury to the head, it is best to consult a doctor for proper assessment.

What are the physical signs?

Individuals who end up with a head injury might develop physical indications of brain dysfunction. The visible or evident signs simply indicate that a certain degree of damage has occurred to the brain. One of the common signs is a change in the dilation of the pupils.

The third cranial nerve or oculomotor nerve is responsible for controlling the pupil dilation. When damage or irritated by inflammation, the pupils will no longer react appropriately or present as varying sizes. Some of the nerves that control the facial muscles can lead to paralysis when damaged. The individual will also have drainage of fluid or blood from the ears or nose which is a serious sign. In severe cases, the brain can also become badly damaged that can result to paralysis and even coma.


Seizures typically occur at some point after sustaining a head injury and the greater the injury; the more likely seizures will develop. In addition, individuals who sustained brain trauma are more likely to end up with seizures. Oftentimes, seizures will start almost right away but the onset is often delayed for week or months after the injury.
