PART 3: Traumatic Brain Injury



I first met Alma Hall at a Wounded Warrior Wives’ retreat in El Paso.  As fate would have it, she was my roommate for the weekend, and we quickly found we had many things in common.  Both of our husbands served as combat medics in the Army, both had similar struggles with PTSD, but then she began talking about his traumatic brain injuries and how it had affected him and their daily lives.  He had memory problems, and she had to be the one to remind him when to take his medications and sometimes even when to bathe.  Their latest battle had been with brushing his teeth.  She would ask him if he had brushed his teeth, and even after pausing for a moment to think long and hard, he could not remember.  Using a play out of the Parenting 101 book, she would check his toothbrush—dry. 

She confessed she was nervous to be away from him for the weekend because he relied on her memory to compensate for his own.  Even though he had good friends who were going to be checking in and spending time with him while she was away, she was as anxious as a new parent leaving a newborn with a babysitter for the first time.

Between sessions, Alma, like many other wives, could be found in the hallway, cell phone to her ear, calling to make sure nothing had fallen apart and to remind him to brush his teeth.  On the last day, breakfast moved straight into another class, and she wasn’t able to call as early as she had wanted.  She quickly slipped out, and when she returned, she was wiping tears from her eyes.  Concerned, many of us asked what was wrong.  She began to beam with tears of joy streaming down her cheeks.  “He remembered to brush his teeth,” she announced proudly.  And the room erupted with cheers.

TRAUMATIC BRAIN INJURY
PTSD isn’t the only “invisible injury” that our troops deal with when they return home from war.  Traumatic brain injury (TBI) has also become a signature wound of the war on terror, and like PTSD, sometimes symptoms do not arise, or are not noticed, right away.  PTSD and TBI share many common symptoms, so there can be confusion as to which one is causing the problems, and can sometimes cause a TBI diagnosis to be missed altogether.  What’s worse is when differing symptoms of both begin to compound and even clash, causing new and worsening problems.  Just like not every soldier has PTSD, not every soldier with PTSD has a TBI, but knowing can make a world of difference in the treatment of both.

WHAT IS TBI?
“Why do you look inside a carton of eggs before you buy it?  Because even though the outside of the carton may seem perfectly normal and intact, one of the eggs inside may be cracked.  The same holds true for TBI.  Your Veteran’s head may show no signs of being injured, but the inside, his or her brain, may in fact be damaged.” –Brannan Vines,

A traumatic brain injury occurs when an outside force (trauma) injures the brain.  This can happen with a blow to the head in sports, falls, and other physical contact with a hard object.  It can happen when nothing directly hits the skull, like sudden acceleration or deceleration in a car crash.  TBIs can also be the result of a blast, such as those experienced in Iraq and Afghanistan from improvised explosive devices.  In addition to the blast possibly causing the warrior to be thrown down or hit their head, the shock waves themselves can cause irreversible damage. 

Some may ask why there seem to be more cases of TBI in today’s military than in previous conflicts.  Why wasn’t brain injury more common in other conflicts?  The two easiest answers are advances in armor and the increased use of explosives by the enemy.  Technology has brought military armor a long way, and warriors are surviving many injuries that would have been fatal in the past.  IEDs and suicide bombers have been the weapons of choice for terrorists who seek to inflict major damage to a large number of people.  Veteran advocates estimate that 10-20% of Iraq veterans, or 150,000-300,000 service members have some level of TBI.

In the TBI tip card from Lash & Associates Publishing, Harvey E. Jacobs, Ph. D. and Flora M. Hammond, M.D. explain the types of brain injuries, causes, symptoms, and how to recognize traumatic brain injury.

“The causes and effects of a traumatic brain injury vary with each person.  The location and size of the blow or impact determine what parts of the brain are injured.  No two traumatic brain injuries are alike… Most commonly, the person does not lose consciousness when a brain injury occurs.  These are called mild brain injuries, but they can cause many difficulties that are not necessarily mild.  The person may feel dazed or just a little confused for a brief time and then return to work or usual activities.  Problems may develop later.  Sometimes people wrongly assume the effects of a brain injury are caused by something else such as combat fatigue, illness, stress, or nerves.”

Another strike against warriors who received a TBI in a warzone is the lack of rest that is crucial to recovery after a brain injury.  When an athlete sustains a concussion, the doctor will typically order rest so the brain has time to heal and recover.  This is not an option for warriors who are still in an extremely stressful environment with a mission to accomplish.  Repeated blasts and injuries, often before the previous injury has healed with very little rest in between, can compound to make very serious changes to the way the brain functions. 

“Injury on the football field can be devastating, but after the concussion, people aren’t trying to kill you,” says Dr. Shane McNamee from the Richmond VA.  “People aren’t shooting at you.  You’re not seeing your loved ones, your brothers, maimed and killed in front of you.  You’re not then pressed out the next day, to go back out and do it again, and again, and again.”

In recent years, the military has also begun to notice the increased risks for concussions and multiple TBIs.  In 2011, PBS ran a series called “Where Soldiers Come From”.  In the episode on TBI, they talked about changes the military has made to stop warriors from suffering multiple concussions.

“The Pentagon recently released a new policy for the treatment of TBI, which includes a mandatory 24-hour rest period after a blast and a complete neurological assessment for anyone who’s had three or more concussions.  The United States Congress has mandated that military and veterans’ hospitals screen all service members returning from combat assignments.  Yet even when TBI is properly diagnosed, it is difficult to treat properly.  Often a soldier does not realize he or she has suffered a concussion—symptoms may first surface months or years later.”

SIMILARITIES TO PTSD
Some warriors who return home with PTSD often don’t realize they could have a TBI because some of the symptoms overlap.  Difficulty with short-term memory could be written off as cognitive problems from PTSD and lack of sleep.  Substance abuse can be suggested as the warrior trying to avoid, but instead could mean that the area of the brain regulating impulse control and judgment have been compromised.  Some studies also suggest that having a TBI increases the risk for PTSD in service members.

Marilyn Lash has over 35 years’ experience working with persons with disabilities and is a respected key-note speaker on the topic of brain injuries.  She has spoken at many wounded warrior wives retreats, including the El Paso retreat mentioned earlier.  She says the five areas that she most often hears about being common in both PTSD and TBI are cognition, depression, anxiety, insomnia, and fatigue.  When asked if there was one area that seemed more common in veterans with PTSD and TBI, she said it would probably be those in terms of thinking, such as memory changes, organizing, problem-solving, and other executive skills.

SYMPTOMS
TBI symptoms can be broken down into four categories: Physical, Cognitive, Communication, and Emotions and Behaviors.  Again, every TBI is different, and symptoms are usually a result of what part of the brain was injured. Some people may have several different symptoms while others only have a few.  These are just general lists of possible symptoms.

Physical: headaches; seizures; nausea; weakness/paralysis; balance; clumsiness; changes to vision, hearing, smell, taste, or appetite; sensory sensitivity (sensitive to light, sound, smells, etc.); fatigue; sleep disorders.

Cognitive: amnesia; memory problems; slowed processing; organization and planning; poor judgment; inability to multitask; poor initiation; confusion; easily distracted; repetitive thoughts and comments; impulsive.

Communication: slurred speech; word finding (trouble finding the right word- “it’s right on the tip of my tongue!”); not on topic; trouble listening; dominates conversation; problems with reading and writing; change in rate of speech (usually slower); repetitive storytelling; literal; comprehension problems.

Emotions & Behaviors: anxiety; depression; self-centered; short temper; frustrated; inappropriate crying or laughing; mood swings; rigid or stubborn; dependent; personality change; disinhibited.

If you or a veteran you know has been exposed to blasts, has had a head injury, or has had repeated concussions while serving overseas and you have noticed any of the above changes, then it’s time to be checked for a TBI.

LIVING WITH TBI
It was after the El Paso retreat that I began to reassess my husband’s behaviors and symptoms.  I knew he had been in multiple blasts and had lots of hard landings that made him “see stars” when he jumped out of planes with the 82nd Airborne.  He had a lot of the symptoms that were common to TBI but not PTSD.  We were both more than shocked to find when he asked to be tested at the VA for TBI that it was actually already in his medical record.  They knew very early on what we did not know: that TBI had caused significant changes to the way he functioned each day.

Alma Hall picked up on signs that something was not right immediately, even from another continent.  Her husband, Russ, called her after his vehicle took a direct hit from an IED and flipped over.  He wanted to let her know that he was okay, but she could tell something was off.

“He kept repeating himself over and over again, and he was speaking very slowly,” she said.  “It just didn’t sound right.”

His fellow combat medics showed concern, but as senior medic, he waved them off saying he was fine.  He completed his tour and returned home in December 2007.  It was then that Alma really began seeing the red flags that he was not “fine”.

“It was pretty obvious,” said Alma.  “He had developed a stutter, he would repeat things within a few minutes of each other, he had horrible migraines, and he would constantly lose his train of thought.”

Russ has since had two years of occupational therapy to help with the cognitive issues as well as two and a half years of speech therapy.  While it’s not a permanent fix, they did teach him tools and coping skills to make living with a TBI easier.  She still has to remind him to take his meds, guide him through the steps for everyday tasks, and yes, sometimes still remind him to brush his teeth, so it’s easy to see why something so small would be such a big celebration when he remembered without prompting.

Still, just as with PTSD, there are good days, and there are bad days.

“If he is extremely tired, has had very little sleep, or has migraines, the first thing I notice is his speech is wonky,” said Alma.  “He’ll start throwing out words that don’t pertain to anything about what he is saying.  His short-term memory loss is also ten times worse.”

Sometimes it’s hard to explain these symptoms to others, especially civilian wives.  I’ve spoken to many wounded warrior wives who are frustrated when they try to describe what it’s like, only to have someone say, “Oh, that’s just a man for you.  They don’t listen, and they never remember.”

I’m sure everyone has had those moments when you walk into a room and forget what you went in there for in the first place.  That’s common, but much, MUCH more frequent, and sometimes on a much larger scale.  There have been times my own husband has gone to Amarillo, only to hit I-40 and think, “What was I coming to town for?”  He confessed to me that there had been times that he simply drove around town for hours, hoping to see something that would spark his memory.

We also have the same conversations over and over, sometimes in the same 10-minute time frame because they don’t remember having it the first time.  The times when there is disagreement over who said what and when are daily.  Getting flustered and giving him a hard time about not remembering something I said or asked  him to do doesn’t help, so we chalk it up as a “TBI moment” and move forward.  Just as I have learned not to take it personally when he forgets, he has learned not to take it personally when I remind him ten times a day about an upcoming appointment or something he needs to do.

“The best advice I can give is to be patient,” said Alma, a sentiment that echoed from every PTSD/TBI group I posed the question to.

LONG-TERM EFFECTS
Multiple studies have found an increased risk for Alzheimer’s in people with TBI.  Moderate and severe TBIs (respectively) are associated with a 2.3 and 4.5 times increased risk for Alzheimer’s.  If you were to look at some of the early warning signs of Alzheimer’s, you would see that most of those symptoms listed are also symptoms of TBI.  Knowing you have a TBI, learning ways to cope, and always being aware of any changes or worsening symptoms are the best way to detect problems later on.

There have also been studies that suggest people with TBIs have a higher rate of suicide.  Add that to the higher rate because of PTSD, and it can be a scary situation for the veteran who has both.  It has also gotten attention from outside the military.  Athletes, particularly football players who take hard hits for a living, are showing their vulnerability as well.  The NFL has been in the spotlight as some of its former players have committed suicide the past few years with some experts theorizing a link between suicide and brain injuries.  Junior Seau, NFL linebacker, took his own life this year, and preceded by Dave Duerson who left a note asking for his brain to be sent to the “NFL brain bank” for study.  This fall, the U.S. Army and NFL publicly announced that they would be teaming up to spread awareness and pioneer research on TBI.

There seems to be new research coming out every day about TBI and its effect on the military and athletes.  Technology is beginning to catch up, bringing new imaging machines and therapies, but they are still out of reach for many veterans, especially in rural areas.  Many of the first troops who returned home from Iraq and Afghanistan did not have the information on TBI that has become more common and readily available.  Many who separated before 2008 were not tested for TBI or may have had symptoms that began to manifest years later.  And just like PTSD, it’s created another group of disabled veterans with invisible wounds who struggle every day with a public that doesn’t understand.



YOU ARE
NOT ALONE.
