A head injury can be any sort of injury to the brain, skull, or scalp. Head injuries range for a mild bump to a traumatic brain injury. Concussions are among the most common brain injury along with hematomas and hemorrhages.
An injury can happen from two causes. The head could either obtain injury from a blow to the head or from shaking. Falls, car accidents, assaults, and sports accidents are among the most common ways to obtain a head injury. Though the human body has a thick skull, severe injuries are still able to occur.
When the blood clots outside of a blood vessel it is called a hematoma. Hematomas in the brain are very serious because it can lead to pressure building inside the skull. It can result in permanent brain damage and cause you to lose consciousness. Patients that take blood thinners are more likely to develop a hematoma and it can be caused by even a minor head injury.
When your brain starts to hemorrhage, it means there is uncontrolled bleeding. Subarachnoid hemorrhage means that the bleeding is in the space around your brain and an intracerebral hemorrhage is bleeding within the brain tissue. The subarachnoid hemorrhages can result in headaches and vomiting. Depending on the severity of intracerebral hemorrhages, could affect the result of this trauma. There can be a large amount of blood which can lead to pressure buildup or death.
Probably the most common head injury that comes from playing sports, concussions are due to an impact to the head that is severe enough to cause a brain injury. Concussions occur when the head hits against a hard surface leading the brain to hit against the skull. Vomiting, sensitivity to light, memory loss, insomnia, and more symptoms can result from a concussion. Depending on the severity of the concussion or if it is a repeated concussion, it could lead to permanent brain damage and sometimes death.
Assessing if a head injury is serious or not could be difficult just by looking. Some minor injuries could bleed a lot while major traumas could not having any bleeding. Head injuries should be treated serious no matter what.
