What are some of the most common types of head injuries?

Concussions: These commonly cause survivors to briefly lose consciousness, become disoriented and confused — or suffer temporary or more lasting memory loss.
Skull Fractures: Signs of this type of injury can include: bruising, bleeding, and swelling – although they may not be visible. Permanent brain damage (or even death) can occur after the most serious skull fractures – especially when they aren’t promptly evaluated.
Intracranial hemorrhage: Tests are often run to determine whether TBI patients have developed any bleeding inside their skulls that may also involve blood clots.
Cerebral contusions: These types of injuries often result in both memory or attention difficulties.
These are just some of the many types of traumatic brain injuries that people may suffer following different types of serious blows to the head.
