Traumatic Brain Injury (TBI) is getting more attention than ever before. Media outlets have done a great job at highlighting the impact of TBI and Chronic Traumatic Encephalopathy (CTE) on football players. This extra attention and research are great news for anyone that's experienced a TBI.
The reality is that TBI and CTE are not only found in football players. According to the Centers for Disease Control (CDC), in 2014, 2.87 million people ended up in an emergency room because of a TBI.
Neuropsychological evaluations for traumatic brain injury are one of the more common types of evaluations that we complete. Most of our patients are very anxious when they come and see us for an evaluation.
We want to help ease your anxiety and provide you with more information on what a TBI is and how it can impact you.
The goal of this blog post is to talk about the leading causes of TBI, how a TBI is diagnosed, how a TBI impacts your brain, and how a neuropsychological evaluation for a traumatic brain injury can help you.
The typical causes of TBI stay fairly consistent year over year.
Here are some stats from 2013:
Every year in the United States over 50,000 people die as a result of a TBI. TBI's make up around 1/3 of all injury-related deaths.
Around 80,000 to 90,000 people a year experience a life-long disability as a result of a TBI.
We didn't include all of these stats to scare you. We want to show you how common a TBI is and how many people it impacts every single year!
TBIs are broken down into three types:
In order to determine the severity of the TBI, doctors use three criteria when they do their assessment in the emergency room.
We've made a simple chart below to help break down how doctors determine the grade of the TBI.
Post-Traumatic Amnesia (PTA) is a state of confusion and memory loss right after a traumatic brain injury. PTA occurs because there are impairments in attention and concentration, which are required to place new information into memory storage.
Here are some of the common signs of PTA:
PTA causes individuals to have “islands of memory”. They can remember bits and pieces of the event but don't have a continuous recollection of what happened.
They also have a hard time forming new memories (anterograde amnesia) and have difficulty remembering information BEFORE the event because of the disruption to their memory system (retrograde amnesia).
PTA ends AFTER the person has continuous awareness of their environment and is able to form new memories.
PTA is an important sign to be aware of because the length of the PTA can help us determine the severity of the TBI. The longer the PTA, the higher the likelihood that the TBI is causing memory impairment.
Here is what PTA looks like following a closed head injury.
Mild traumatic brain injuries (mTBI) make up around 75-80% of all TBI cases. . . .
