Sometimes, the symptoms don’t appear so quickly.
For example, this has been the case for a lot of soldiers suffering from traumatic brain injury, or TBI, a signature injury of a war.
The conditions can range from a mild concussion to harsh, visible injury. Some people suffering from a brain injury do not seek care because symptoms may not seem apparent immediately.
So is this the case of Natasha Richardson?
This is what Los Angeles Times reports:
“The head injury Natasha Richardson suffered in a skiing accident Tuesday produced what is often called a “walk and die,” syndrome, which is usually due to delayed bleeding from an artery in the brain, said Dr. Christopher Giza, a neurologist at the UCLA Brain Injury Research Center.”
“In such cases, the patients, like Richardson, appear normal immediately after the injury, walking and talking as though nothing happened. But symptoms can develop within an hour, causing the patients first to suffer impaired speech and vision and then to fall into a coma.”
According to CNN, those injuries are also called “epidural hemorrhage.”
“Blood gets trapped between the skull and the hard layer of skin between the bone and brain, known as the dura matter. As the blood flows from the ruptured artery, the fluid builds and punctures the dura,” the network reported.
