What type of traumatic brain injury (TBI) leads to "Talk and Die" syndrome?

What is "Talk and Die" syndrome?
 
Talk and Die syndrome is the after-effect of a head injury that is commonly seen by neuroscience physicians and surgeons.  (Patients suffer a head injury, assume they are ok, but then decline rapidly.)  Talk and Die syndrome is one of many names describing several different types of brain injuries.  If you type "fatal brain injury" into Google, you'll be able to better understand the serious attention doctors give to the many types of existing brain injuries.

The actual injury known to cause Talk and Die syndrome is an epidural hemorrhage.  This type of head injury causes blood to become trapped between the skull and the hard layer of skin between the bone and brain known as the dura mater. As the blood flows from the ruptured artery, the fluid continues to build until it punctures the dura.

Most car accident victims who fracture their skull are often unaware of their injury. In these cases, the fracture typically occurs just above the ear, in the temporal bone. If the artery that runs above the skull gets torn and begins to bleed above the lining of the brain, pressure begins building on the brain causing the brain to swell.  As the blood flow to the brain is reduced the patient begins to feel the symptoms associated with Talk and Die syndrome.     

IMPORTANT: the initial impact does not have to be hard at all. And a delay in any noticeable symptoms or signs of injury can range from three minutes to three hours, or several days, after their car accident or slip and fall.

Getting to a hospital within the first few hours after your accident is critical.  Not doing so can result in permanent brain damage.
