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.
When to See a Doctor
Seek professional care if you experience any of the following symptoms
- Injury to head
Possible Causes
Generally, Head injury can be related to:
- Concussion
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 Axon Injury
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.
- Head Contusion (Minor)
Minor head injuries often cause a bump or bruise. It's unlikely there will be any serious or permanent damage.
- Cervical Spondylosis
Related Serious Diseases
Sometimes, Head injury may be related to these serious diseases:
- Acute Subdural Hematoma
Acute subdural hematoma is the buildup of blood between the brain and its outermost covering and can be a medical emergency. It is usually caused by a head injury. Older age, blood-thinning drugs, and alcohol abuse can increase the risk.
- Acute Epidural Hematoma
- Cerebrospinal Fluid Rhinorrhea
- Chronic Subdural Hematoma
- Cerebral Edema
- Cerebral Hemorrhage
