Understanding Closed Head Injury
A closed head injury is when the skull doesn’t break or get pierced. It’s different from a penetrating head injury. These injuries can be serious and need quick, full medical care.
Definition and Types
Closed head injuries have different types, based on how bad they are and which part of the brain is hit. Here are some: Diagnosing Closed Head Injury: Essential Steps
- Concussions: This is the most common type. It happens when a blow to the head causes brain trauma but doesn’t break anything.
- Contusions: These are bruises on the brain. They usually come from a direct hit.
- Diffuse Axonal Injuries: These are very serious. They happen when the brain moves too much inside the skull and hurts nerve fibers.
- Hemorrhages: These are bleedings in or around the brain. They can be epidural, subdural, or subarachnoid hematomas.
Common Causes
Closed head injuries can come from many things. Some common causes are:
- Falls: Falls are a big cause for all ages. They can lead to many types of brain injuries.
