Head injury can be as mild as a bump, bruise (contusion), or cut on the head, or can be moderate to severe in nature due to a concussion, deep cut or open wound, fractured skull bone(s), or from internal bleeding and damage to the brain requiring emergency medical care.
Seek professional care if you experience any of the following symptoms
Generally, Head injury can be related to:
Concussion is a brain injury caused by a blunt blow to the head or a violent shaking of the head and body. The effects are usually temporary.
Diffuse axonal injury (DAI) is a type of damage that occurs to nerve cells as a result of traumatic brain injury (TBI). TBI is most often caused by blunt head trauma. DAI is sometimes accompanied by severe alterations in someone's level of consciousness, such as lethargy or coma.
Minor head injuries often cause a bump or bruise. It's unlikely there will be any serious or permanent damage.
Sometimes, Head injury may be related to these serious diseases:
Acute epidural bleed or epidural hematoma is when bleeding occurs between the outer membrane covering the brain (dura mater) and the skull. The most common cause is a head injury with skull fracture accompanied by an injury to an artery.
Your doctor may ask these questions to check for this symptom:
