Traumatic Brain Injury - Part V - Prevention

Every 16 seconds in the U.S., a person suffers a TBI. This entry is related to how to PREVENT being a statistic. For a traumatic brain injury (TBI), there is no cure, only prevention. What can a person "do" to prevent this? Most things are common sense, but my suggestions focus on falls because they are the biggest cause (see TBI Part II Causes). These suggestions have been collected from various websites and from my own personal experience. Links to all of the other websites appear on the TBI entries I've made (click on the Misc/Brain Dump page above for related posts or the related links at the end of this post).

Falls can occur in nearly ANY part of daily life, and we rarely pay attention to each and every move we make. Here are some common sense things that can help you prevent a fall and possible TBI:
  • Use handrails on stairways and look at the steps when walking 
    • Stop reading the mail or magazine 
    • Look for items that have been left there
  • Provide lighting on stairs for people with poor vision or who have difficulty walking
    • A nightlight at the top or bottom is a good idea at night
  • Sit on safe stools and chairs. 
    • Wobbly chairs collapse, stools tip, throwing you to the floor
  • Do not place obstacles in walking pathways (such as stairs, hallways and traffic patterns)
  • If a cabinet door is open on a cabinet in the kitchen and you drop something on the floor, be careful standing back up or your head may impact against the bottom of the open door
  • Use a mat/rug on bathroom and kitchen floors (near the tub/shower and sinks)
    • Those 2 floors are notorious for getting wet. You do NOT want to slip on one (that is what happened to me). 
    • Trying to get back on your feet isn't easy and you can repeatedly fall, making the injury even worse.
The second largest part of our lives that cause falls, are sports and physical activities. Here are some suggestions focused on them. Most sports (football, baseball, soccer, lacrosse, etc.) have specific requirements for the gear that must be worn to protect the various parts of the body. I am focusing on the points below because they are about helmets, which help prevent TBIs. I'm not here to explain the pros or cons about helmets, simply provide you with some suggestions and information.
  • Always wear a helmet when on a bicycle, motorcycle, scooter, snowmobile, jet-ski
  • State Helmet Laws
    Some Local Helmet Laws
    White states have no known helmet laws

    • Some states have laws about helmets for under 18 age people riding bicycles and this site [link] shows info and has a lot of good links about other issues surrounding helmets. The image to the right is an overview of the states that have known/reported laws.
  • Wear a helmet while skiing, snowboarding, skating and skateboarding
  • Wear a helmet when participating in contact sports
    • Not just in "official" ones, but even during the weekend pick-up games
I mention contact sports in the last bullet because I am a ref for a roller derby league and have been at countless bouts where a skater (or even ref) has been knocked down and hit their head on the floor. Helmets are required to be a competing skater or ref (yes, they sometimes get taken out). Basically what a helmet does in any of the activities mentioned above is PREVENTS a fall from being a severe TBI and reduces it to a mTBI, more commonly known as a concussion.

Overall, use common sense in your daily life and when taking part in any physical activity... your head will thank you.

Traumatic Brain Injury (TBI) - Part IV - Recovery & Rehab

This entry is an overview of what is involved in recovery and rehab for a TBI victim. Chances are that you know someone that has experienced a TBI. Peppered throughout the information are links to sites that contain more details on each topic.

Obviously the medical team will address any physical injuries that require attention. Something to keep in mind about that though, is that a mild TBI (mTBI) or closed head injury may not be diagnosed until well after all of the physical injuries have been tended to. Refer to the TBI Part III - Types for more info about those.

Before recovery/rehab can occur, there has to be a diagnosis of the type or level of TBI has occurred. The victim may be on life saving medical machines, medicated and the evaluation for brain injury will be hard to determine until the victim is physically stable and conscious. Remember, a TBI is not "visually apparent" because it happens inside the head. This is most apparent in a "closed head injury" (explained in TBI Part II).  As explained on one website [click HERE] there are several steps in the "method" of diagnosis:
  • A detailed neurological examination will bring out evidence of brain injury.
  • Brain imaging with CAT scan, MRI, SPECT and PET scan.
  • Cognitive evaluation by a neuropsychologist with formal neuropsychological testing.
  • Evaluations by physical, occupational and speech therapists help clarify the specific deficits of an individual.
Once a diagnosis has been made, a plan for recovery and rehab can be penciled on paper. Of course it will cover any of the physical injuries, but the "length" of the rest of it depends on the individual victim and the success they achieve. It becomes a thought that "only time will tell." For a concussion or mTBI, the victim is typically discharged within a time span of a few hours up to a day after the injury occurs. For more severe types, they may be held in the hospital until they are physically stable and then transferred to a rehab center that specializes in TBIs. For example, I was in 2 different hospitals 2,100 miles from "home" before I was stable enough to transfer to a rehab center that was closer to my house.

So, the question that comes to mind of the family or friend of a TBI victim, is "OMG, what happens at the rehab center?!?!" I'll summarize what can be found on this website [link]. I'm glad you are reading this, but not to be sarcastic, if you are ever checked into a TBI center, you won't remember this or be aware of it until you recover. This is more for the family and friends of a victim. I've highlighted the key points of what happens after the physical things are tended to and the victim is finally in a true TBI center. I've put my personal observations after.

Understanding Traumatic Brain Injury
Similar to the acute care facility, the TBI patient will be cared for by a team of professionals who specialize in the care of trauma victims. Their goals are to:
  1. Stabilize the medical and rehabilitation issues related to brain injury and the other injuries.
  2. Restore lost functional abilities.
  3. Provide adaptive devices or strategies to enhance functional independence.
  4. Begin to analyze with the family and the patient what changes might be required when the person goes home.
Each day, the patient will participate in therapy. Initially, the patient may require staff assistance for even the most simple activities:  brushing teeth, getting out of bed and eating.  The patient also may require staff for safety because there is a risk of falling, eloping (trying to get out of the hospital to go home) or getting hurt. The patient may be confused and forgetful.

The Rehabilitation Team
The Physiatrist is the team leader in the rehabilitation program. The physiatrist is a physician specializing in physical medicine and rehabilitation. The physiatrist will assess and prescribe the treatment and direct the team.

The Neuropsychologist will assess patient's changes in thinking and behavior. Changes could include:
  • Poor memory, attention, concentration, decision-making
  • Impulsivity, disorientation
  • Language and communication abilities
  • Inability to speak or understand when spoken to
Many patients are unaware of the changes in the brain and how those changes affect their daily lives.  A patient may not understand what has happened and may be distraught by being away from home.

The Rehabilitation Nurse assists patients with brain injury and chronic illness in attaining maximum optimal health, and adapting to an altered lifestyle. The focus of nursing care is on:
  • Sleep pattern disturbance
  • Impaired verbal communication and comprehension 
The Physical Therapist job is to minimize or overcome paralyzing effects related to the brain injury. PTs will assess:
  • Balance, posture, strength
  • Increased sensation of sensory-motor activities
  • Pain management
The Occupational Therapist assesses functions and potential complications related to the movement of upper extremities, daily living skills, cognition, vision and perception. OTS  help determine the best ways to perform daily living skills including showering, dressing and personal hygiene. The OT also will look at skills to prepare the patient for a return to the home. These skills include:
  • Cooking, grocery shopping
  • Banking, budgeting
  • Readiness for returning to work by assessing prevocational and vocational skills
Now a personal explanation of being released and being allowed to return "home." The victim of a TBI will only be released from the rehab center once they can demonstrate that they are capable of performing all of the above (and more). They will also have to schedule the follow up assessments, to make sure they are progressing down the path of life, and not experiencing a "relapse." It takes months to "recover" from a severe TBI, but years to "rehab."

Personal Observations
You have to go through physical therapy for a few reasons. Your muscles may be weak from being immobile. Second point is because of how your brain is "misfiring." Physical therapy is to get your muscles active again, but also because the damage to your brain means that it doesn't send the signals to the muscles to be active. You will walk A LOT, perform hand/arm/leg exercises, etc. I studied tai chi, qi gong, do yoga, walk my dog about 20 miles per day, and became  a roller derby ref. I stay very active.
Another thing not discussed openly is trying to "elope" or "get away" from where they are. When you become conscious again, and don't know where you are or why you are there, the survival instinct kicks in. You want to "flee." But know, the TBI victim may be restrained to prevent it. It stops more injuries from occurring until the person is able to safely conduct a "normal" demonstration of getting through the day. A lot of TBI victims may spend some time cuffed or strapped to their bed to prevent them from trying to get away until they are conscious enough to understand that they shouldn't.
Another point is related to rehab exercises to regain the ability to communicate. They will track your ability to communicate, but the don't really provide therapy to assist. You have to do it on your own. I suggest playing cards, doing crossword puzzles, sudoku, word finds, read the newspaper, etc. Just letting a TBI victim watch TV or listen to the radio doesn't do it because it doesn't challenge the brain.
I highlighted the rest of the points just to give you a summary of what a TBI victim will be analyzed on before they are "released" to go home. What isn't really "discussed," is what your restrictions will be when released. You may not be allowed to drive, go up the stairs, use hand tools, be alone in the bathroom, go anywhere unsupervised, cook, clean, etc. It all depends on what level of success you have at the rehab center and at follow up appointments, before they begin to remove your restrictions..
Another thing not mentioned in rehab is how some other things in your body may change. They will tell you that your sleep patterns may change (you may need less or more), but they don't tell you that your metabolism and hormone levels may also change. The only way they mention the hormone changes is to say that "you will be more impulsive and/or uninhibited in your expressions of your feelings." Yeah, sorry to say, but THAT affects everyone around you. Same with metabolism. You may need MORE or even maybe LESS meals.


I could probably write a novel about my personal experience and observations, but I just wanted to provide some overviews about traumatic brain injuries and concussions so more people would begin to learn more about them. There are 1.5 million cases every year... that's a LOT. And those are only the counts of the victims that are checked into a hospital. If you receive a concussion, go to the ER, and are released shortly after, you don't count because it isn't reported. So, ask yourself, how many concussions occur that aren't counted in the stats? Hmmm... makes you wonder... Just be careful out there...

Traumatic Brain Injury (TBI) - Part III - Types

While this [link] explains the "effects" of a TBI, I feel that it better explains the 2 types (mild & severe) of a TBI, which is why I'm summarizing it and providing some personal observations after that. Yeah, this entry is going to be LONGER than normal because this is what needs to be most understood about TBIs.

Most are unaware of the range of a TBI or its overwhelming nature. TBI is common, and will be overlooked initially when the medical team is focused on saving the person's life. TBIs can be categorized into 2 levels: mild and severe. Let's talk a little about them. For more information, click on the links above.

Understanding Traumatic Brain Injury
A TBI is classified as mild if loss of consciousness, confusion and disorientation is shorter than 30 minutes. The victim may experience headaches, difficulty thinking, memory problems, attention deficits, mood swings and frustration. Even though this type of TBI is called "mild", the effect on the family and the injured person can be devastating. Unfortunately, the family and friends may be the recipients of the frustration of the victim, but they don't realize "why" they are. And, the victim doesn't realize that they are venting on them.

The most common mTBI is a concussion. Even though most sports require pads and helmets, it still occurs. Wearing a helmet helps prevent 60% of mTBIs, but they can still occur. I'll discuss more about helmets in the prevention entry. A key point to understand about a concussion is that the effects can last up to a year or more after the injury.

Common Symptoms of Mild TBI (mTBI):
  • Fatigue, sleep disturbances, memory loss, dizziness/loss of balance 
  • Irritability-emotional disturbances, depression
Other Symptoms Associated with Mild TBI (mTBI):
  • Nausea, loss of smell, sensitivity to light and sounds
  • Mood changes
  • Slowness in thinking
These symptoms may be delayed days or weeks before they show up.  They are subtle & often missed by the injured person, family and doctors. The victim "appears" normal. Family and friends notice changes in behavior before the injured person realizes there "is" an issue.

Observations
Frustration at school, work or when performing daily tasks occur. Trust me, I know... I've gone through this and continue to work through it. Unfortunately, it affects those around me too, and I'm not always aware of that until they point it out to me.

Understanding Traumatic Brain Injury
TBIs result in permanent neurobiological damage that can produce lifelong deficits to varying degrees. Severe brain injury is associated with loss of consciousness for more than 30 minutes and memory loss after the injury longer than 24 hours. Survivors may have limited function of arms or legs, abnormal speech or language, loss of thinking ability or emotional problems.

The impact of a moderate to severe brain injury can include difficulties with attention, concentration, being distracted easily and impulsive responses. Other key effects of a severe TBI are:

Speech and Language
  • difficulty speaking and being understood
  • slurred speech
  • speaking very fast or very slow
  • problems reading or writing
Sensory
  • blurred vision, problems judging distance
  • decrease or loss of hearing, ringing in the ears (tinnitus)
  • loss or diminished sense of smell
Social-Emotional
  • Lack of motivation, irritability, aggression
  • Depression
  • Denial/lack of awareness
Observations
Another key thing not mentioned on most websites about TBIs is prosopagnasia (commonly called "facial blindness"). This is when a victim cannot recognize someone just by looking at their face. I know I suffer from this because I once spent an half an hour visually "searching" for a family member that had been standing 20 feet away from me the whole time, but I didn't recognize them. Yeah, this will probably be another blog entry.
The abnormal speech & slurred speech occur more often when the victim is tired or stressed. I have had several people approach me and ask me if I was drunk because my speech was slow, slurred, and not easy to understand. No, I hadn't been drinking, but the connections between the brain and the voice are stressed more, so it "sounds" like that I am.
When in a tired, stressed, anxious, or distracted environment, I have been overly impulsive (verbally) to things. A victim can lose their mental "filters" and end up saying or doing things they wouldn't "normally" have done before. It is because the connections between emotions and expression are stressed more than normal, and the person is not performing a mind check before they utter or do something. And when they DO utter them, they probably sound "drunk."
Sometimes there is a disconnect in the brain of a victim because they "know up here" what they are trying to communicate, but the signal never makes it to the tongue. There are times that I know what I am thinking, but the actual words don't come out of my mouth, and that leads to frustration when you have to ask someone what the word is for something as simple as a "doorbell," or "remote control." It leads to more frustration, but also personal embarrassment, which typically leads to even more emotional feelings related to self-esteem.
Sometimes the victim has more of a ROM drive brain but not a RAM drive brain (this is related to memory). I can tell you about things I cooked over a camp fire 2 decades ago, but I can't remember if I had breakfast this morning. Sometimes I wish I could use a PC code of "C:\del *.*" on my brain and just start over.

Part IV will be about recovery & rehab.

Traumatic Brain Injury (TBI) - Part II - Causes




pie chart of causes of traumatic brain injury
(Photo credit: Wikipedia)
As I mentioned in my TBI - Part I entry, this second part is about what can cause a traumatic brain injury. First, some facts. Followed by personal observations.

The graph to the right (based on a CDC report) shows that the top 3 causes of a TBI are from car accidents, falls, and struck by/against. According to the CDC (United States Centers for Disease Control and Prevention), there are approximately 1.5 million people in the U.S. who suffer from a traumatic brain injury each year.  50,000 people die from TBI and 85,000 people suffer long term disabilities.

This is higher than the combined incidence of Alzheimer's, Parkinson's, and multiple sclerosis.

Brain injuries occur more often than breast cancer or AIDS. One out of every fifty Americans is currently living with disabilities from TBI.


The following information (from HERE), explains the "mechanisms" of the top 2 causes of TBIs. I'm only covering the top 2 because they are the most prevalent. I've highlighted the key points and my personal observations appear below that.
Mechanisms of Injury
These mechanisms are the highest causes of brain injury: Open head Injury, Closed Head Injury, Deceleration Injuries, Chemical/Toxic, Hypoxia, Tumors, Infections and Stroke.
1. Open Head Injury
  • Results from bullet wounds, etc.
  • Largely focal damage
  • Penetration of the skull
  • Effects can be just as serious as closed brain injury
2. Closed Head Injury
  • Resulting from a slip and fall, motor vehicle crashes, etc.
  • Focal damage and diffuse damage to axons
  • Effects tend to be broad (diffuse)
  • No penetration to the skull
Personal Observations:
Some things that aren't mentioned above that were my personal observations about TBIs:
It make sense why "falls" and "traffic accidents" cause TBIs, because the head is prone to striking something hard. What came to mind about the "struck by/against" was mentioned in my TBI Part I entry, that a friend's nephew was playing lacrosse when it happened.
My TBI was in the "falls" category. I was at a work conference and stepped out of the shower because I left my shampoo on the counter. I fell on the wet tile floor... repeatedly... According to the doctors, 6-8 times. My recommendation is to always be safe in the bathroom.
A side thought & some reading on websites confirms that a TBI is part of the Shaken Baby Syndrome. Think about it...when shaking a baby, their brain is bouncing around in there and it kills brain cells when that happens. My recommendation is to not do it.

Traumatic Brain Injury (TBI) - Part I

Recently a friend told me that the nephew of a friend suffered a traumatic brain injury (TBI) while playing lacrosse. It made me cringe a lot, not because of the sport being played, but because I've also suffered a TBI. Hence, a series of blog entries related to a traumatic brain injury (TBI), one of the most misunderstood injuries in North America.

As a technical writer, I will keep things factual but I would be remiss to not include some personal observations about my experience. Bear with me... One of the best websites that explains a TBI in a little more detail than I am going to do, is the Traumatic Brain Injury site.

So, the point of this entry is to explain "what" a TBI is. Future entries will cover causes, types, effects, and recovery/rehab. Rather than reinvent the wheel, this is what the above site & links below explain. I have highlighted some key points, and added my comments after the definition:
Understanding Traumatic Brain Injury

     Traumatic brain injury, often referred to as TBI, is most often an acute event similar to other injuries. That is where the similarity between traumatic brain injury and other injuries ends. One moment the person is normal and the next moment life has abruptly changed.
     In most other aspects, a traumatic brain injury is very different. Since our brain defines who we are, the consequences of a brain injury can affect all aspects of our lives, including our personality. A brain injury is different from a broken limb or punctured lung. An injury in these areas limit the use of a specific part of your body, but your personality and mental abilities remain unchanged. Most often, these body structures heal and regain their previous function.
     Brain injuries do not heal like other injuries. Recovery is a functional recovery, based on mechanisms that remain uncertain. No two brain injuries are alike and the consequence of two similar injuries may be very different. Symptoms may appear right away or may not be present for days or weeks after the injury.
     One of the consequences of brain injury is that the person often does not realize that a brain injury has occurred.
DEFINITION:
There are several ways to describe brain injuries.  The brain is enclosed in the bony vault of the skull.  The cerebrospinal fluid surrounds the brain and, most of the time, protects it from impact with the skull.  If there is a rapid force applied to the skull or rapid deceleration of the head, the brain may strike the inside of the bony vault.
Brain tissue may stretch or tear because of the rapid movement.  This can injure the nervous tissue of the brain directly.
Personal Observations:
Some things that aren't mentioned above that were my personal observations about TBIs:
You can't "SEE" a TBI when it occurs inside the head. There aren't any scars (other than how it was caused or hospital equipments used). For some TBI injuries (like mine), there are no visible scars related to it.
A TBI will not only affect the victim, but their family, friends, significant others, employers / employees. They have to adapt to the changes that you've gone through, and be supportive during your recovery/rehab. BUT, you need to ready to accept that the TBI has changed THEIR life too.
The victim of the TBI will not realize it happened when it did. In my occurrence, I didn't know I had a TBI until several weeks after it happened. Why so long? I had to come out of my coma and begin to recover enough to understand what all of those people standing around my hospital bed were even talking about.
