Brain injury and memory problems

HPRC Fitness Arena: Mind Body, Total Force Fitness
Many service members have been affected by traumatic brain injuries. Some have memory problems too. Learn more.

Since 2000, around 350,000 service members have been affected by traumatic brain injuries. TBI often impacts memory, especially short-term memory. Think of long-term memory and short-term memory as “holding bins” for information. Your long-term memory can hold information from several days to decades, while your short-term memory retains information for just a few seconds. And short-term memory is closely associated with working memory (your ability to manipulate information in your head) and sustained attention (your ability to maintain focus).

When memory problems strike, short-term memory, working memory, and sustained attention tend to suffer before long-term memory does. Regardless of cause, memory of a remote event stands out more than newer events because your mind has “rehearsed” the older event repeatedly, essentially embedding it in your brain through repetition. By comparison, your mind hasn’t yet “learned” the newer event. For example, you might recall every detail of combat stories but have difficulty remembering what you ate for lunch. In this case, brain connections that rehearsed the combat story have become solidified, while connections responsible for learning this new information haven’t formed yet.

Depending on the location and nature of the injury, your brain might work differently than it did in the past. This could happen because brain cells that used to “communicate” with each other easily are now being rerouted.

Short-term memory, working memory, and sustained attention also can be affected by other factors such as stress, distraction, poor sleep, depression, anxiety, and/or body toxins. The cause isn’t always obvious. Your doctor can help sort it out, answer questions about your condition, treatment, and prognosis, and refer you to a neuropsychologist for further evaluation. In the meantime, you might find HPRC’s TBI resources useful too.

Protective eyewear could prevent injuries

Blast shockwaves can seriously damage eyes, but immediate treatment could aid healing. Learn more about protecting your eyesight.

Many service members exposed to bomb blasts in the field walk away unscathed—or so it would seem. However, there could be some damage they’re not “seeing.”

High-pressure shockwaves from explosive blasts can cause serious eye trauma. In fact, up to 10% of all blast survivors experience significant eye injuries from projectiles thrown into their eyes, eye perforations caused by the high-pressure blast waves, or effects on the eyes associated with traumatic brain injury (TBI). If you were exposed to a blast while in the field but weren’t otherwise injured, don’t wait to set up an appointment with your eye doctor. Prompt medical attention could prevent permanent injury.

 

Most eye injuries are preventable if you wear protective eyewear on-duty and off-duty. There are many options to choose from the Department of Defense’s (DoD) approved Authorized Protective Eyewear List (APEL). Your vision is extremely important!

Products for concussions hit by FDA

Some dietary supplement products claim to prevent, treat, or cure a concussion. But FDA says to be on the lookout for these claims.

If you suffer from concussions or traumatic brain injuries (TBIs), don’t be tempted to turn to dietary supplements to help you get back on the field. Several dietary supplement manufacturers have promoted products to help with recovery from concussions and TBIs, but there isn’t enough scientific evidence to support these claims. The Food and Drug Administration (FDA) is monitoring this issue and contacting specific companies making claims that their products can prevent, treat, or cure concussions.

FDA warns consumers to avoid using products that claim to prevent or treat a concussion or TBI. For more information about these claims and FDA’s response, see this Consumer Update.

 

Safe return to duty after a head injury

Filed under: Concussion, Injuries, TBI
Mild traumatic brain injuries (concussions) are very common in the military. Learn how you and your doctor can get you safely back to duty.

Returning to duty after a mild traumatic brain injury (mTBI; also referred to as acute concussion) requires a special recovery process. Until now, procedures used by military healthcare professionals were largely based on sports-related mTBI practices, which are not always appropriate for returning Warfighters to military activities and demands. Medical and military experts worked together to develop new recommendations for returning service members to military activity after mild traumatic brain injury. The six-step process includes progressing from rest through light to moderate activity and exercise and eventually to unrestricted activity. Patients cannot progress until they are symptom free at any given stage in the process. Almost 84% of military brain injuries in 2014 were from mTBI/concussions. Some of the most common causes of concussions occur in non-deployed setting. While not all mTBI/concussions are preventable, there are things that you can do to reduce your risk in your day-to-day life:

  • Always wear a seat belt when driving or riding in a vehicle.
  • Wear a helmet when suitable (for example, on a bicycle or motorcycle).
  • Create safe living spaces to reduce falls. Remove or secure potentially hazardous items from floors and overhead.
  • Be aware of your surroundings. Try these Mind Tactics Performance Strategies to improve your ability to control your attention.
