Traumatic Brain Injury (TBI) Definition
Traumatic brain injury occurs when an external mechanical force causes brain dysfunction.
Traumatic brain injury usually results from a violent blow or jolt to the head or body. An object penetrating the skull, such as a bullet or shattered piece of skull, also can cause traumatic brain injury.

Mild traumatic brain injury may cause temporary dysfunction of brain cells. More serious traumatic brain injury can result in bruising, torn tissues, bleeding and other physical damage to the brain that can result in long-term complications or death.

Symptoms
Traumatic brain injury can have wide-ranging physical and psychological effects. Some signs or symptoms may appear immediately after the traumatic event, while others may appear days or weeks later.

Mild traumatic brain injury
The signs and symptoms of mild traumatic brain injury may include:

Physical symptoms

• Loss of consciousness for a few seconds to a few minutes
• No loss of consciousness, but a state of being dazed, confused or disoriented
• Headache
• Nausea or vomiting
• Fatigue or drowsiness
• Difficulty sleeping
• Sleeping more than usual
• Dizziness or loss of balance

 Sensory symptoms

• Sensory problems, such as blurred vision, ringing in the ears, a bad taste in the mouth or changes in the ability to smell
• Sensitivity to light or sound

 Cognitive or mental symptoms

• Memory or concentration problems
• Mood changes or mood swings
• Feeling depressed or anxious

Moderate to severe traumatic brain injuries
Moderate to severe traumatic brain injuries can include any of the signs and symptoms of mild injury, as well as the following symptoms that may appear within the first hours to days after a head injury:

Physical symptoms

• Loss of consciousness from several minutes to hours
• Persistent headache or headache that worsens
• Repeated vomiting or nausea
• Convulsions or seizures
• Dilation of one or both pupils of the eyes
• Clear fluids draining from the nose or ears
• Inability to awaken from sleep
• Weakness or numbness in fingers and toes
• Loss of coordination

 Cognitive or mental symptoms

• Profound confusion
• Agitation, combativeness or other unusual behavior
• Slurred speech
• Coma and other disorders of consciousness

When to see a doctor
Always see your doctor if you or your child has received a blow to the head or body that concerns you or causes behavioral changes. Seek emergency medical care if there are any signs or symptoms of traumatic brain injury following a recent blow or other traumatic injury to the head.

The terms “mild,” “moderate” and “severe” are used to describe the effect of the injury on brain function. A mild injury to the brain is still a serious injury that requires prompt attention and an accurate diagnosis.

Causes
Traumatic brain injury is caused by a blow or other traumatic injury to the head or body. The degree of damage can depend on several factors, including the nature of the event and the force of impact.

Injury may include one or more of the following factors:

• Damage to brain cells may be limited to the area directly below the point of impact on the skull.
• A severe blow or jolt can cause multiple points of damage because the brain may move back and forth in the skull.
• A severe rotational or spinning jolt can cause the tearing of cellular structures.
• A blast, as from an explosive device, can cause widespread damage.
• An object penetrating the skull can cause severe, irreparable damage to brain cells, blood vessels and protective tissues around the brain.
• Bleeding in or around the brain, swelling, and blood clots can disrupt the oxygen supply to the brain and cause wider damage.

Common events causing traumatic brain injury include the following:

• Falling out of bed, slipping in the bath, falling down steps, falling from ladders and related falls are the most common cause of traumatic brain injury overall, particularly in older adults and young children.
• Vehicle-related collisions. Collisions involving cars, motorcycles or bicycles — and pedestrians involved in such accidents — are a common cause of traumatic brain injury.
• About 20 percent of traumatic brain injuries are caused by violence, such as gunshot wounds, domestic violence or child abuse. Shaken baby syndrome is traumatic brain injury caused by the violent shaking of an infant that damages brain cells.
• Sports injuries. Traumatic brain injuries may be caused by injuries from a number of sports, including soccer, boxing, football, baseball, lacrosse, skateboarding, hockey, and other high-impact or extreme sports, particularly in youth.

Explosive blasts and other combat injuries. Explosive blasts are a common cause of traumatic brain injury in active-duty military personnel. Although the mechanism of damage isn’t yet well-understood, many researchers believe that the pressure wave passing through the brain significantly disrupts brain function.
Traumatic brain injury also results from penetrating wounds, severe blows to the head with shrapnel or debris, and falls or bodily collisions with objects following a blast.

The people most at risk of traumatic brain injury include:

• Children, especially newborns to 4-year-olds
• Young adults, especially those between ages 15 and 24
  Adults age 75 and older

What is Post-traumatic Stress Disorder (PTSD)?
When in danger, it’s natural to feel afraid. This fear triggers many split-second changes in the body to prepare to defend against the danger or to avoid it. This “fight-or-flight” response is a healthy reaction meant to protect a person from harm. But in post-traumatic stress disorder (PTSD), this reaction is changed or damaged. People who have PTSD may feel stressed or frightened even when they’re no longer in danger.

PTSD develops after a terrifying ordeal that involved physical harm or the threat of physical harm. The person who develops PTSD may have been the one who was harmed, the harm may have happened to a loved one, or the person may have witnessed a harmful event that happened to loved ones or strangers.

PTSD was first brought to public attention in relation to war veterans, but it can result from a variety of traumatic incidents, such as mugging, rape, torture, being kidnapped or held captive, child abuse, car accidents, train wrecks, plane crashes, bombings, or natural disasters such as floods or earthquakes.

Signs & Symptoms
PTSD can cause many symptoms. These symptoms can be grouped into three categories:

1. Re-experiencing symptoms

• Flashbacks—reliving the trauma over and over, including physical symptoms like a racing heart or sweating
• Bad dreams
• Frightening thoughts.

Re-experiencing symptoms may cause problems in a person’s everyday routine. They can start from the person’s own thoughts and feelings. Words, objects, or situations that are reminders of the event can also trigger re-experiencing.

2. Avoidance symptoms

• Staying away from places, events, or objects that are reminders of the experience
• Feeling emotionally numb
• Feeling strong guilt, depression, or worry
• Losing interest in activities that were enjoyable in the past
• Having trouble remembering the dangerous event.

Things that remind a person of the traumatic event can trigger avoidance symptoms. These symptoms may cause a person to change his or her personal routine. For example, after a bad car accident, a person who usually drives may avoid driving or riding in a car.

3. Hyperarousal symptoms

• Being easily startled
• Feeling tense or “on edge”
• Having difficulty sleeping, and/or having angry outbursts.

Hyperarousal symptoms are usually constant, instead of being triggered by things that remind one of the traumatic event. They can make the person feel stressed and angry. These symptoms may make it hard to do daily tasks, such as sleeping, eating, or concentrating.

It’s natural to have some of these symptoms after a dangerous event. Sometimes people have very serious symptoms that go away after a few weeks. This is called acute stress disorder, or ASD. When the symptoms last more than a few weeks and become an ongoing problem, they might be PTSD. Some people with PTSD don’t show any symptoms for weeks or months.

Do children react differently than adults?
Children and teens can have extreme reactions to trauma, but their symptoms may not be the same as adults. In very young children, these symptoms can include:

• Bedwetting, when they’d learned how to use the toilet before
• Forgetting how or being unable to talk
• Acting out the scary event during playtime
• Being unusually clingy with a parent or other adult.

Older children and teens usually show symptoms more like those seen in adults. They may also develop disruptive, disrespectful, or destructive behaviors. Older children and teens may feel guilty for not preventing injury or deaths. They may also have thoughts of revenge. For more information, see the NIMH booklets on helping children cope with violence and disasters. (from Post-Traumatic Stress Disorder (PTSD) )

Who Is At Risk?
PTSD can occur at any age, including childhood. Women are more likely to develop PTSD than men, and there is some evidence that susceptibility to the disorder may run in families.

Anyone can get PTSD at any age. This includes war veterans and survivors of physical and sexual assault, abuse, accidents, disasters, and many other serious events.

Not everyone with PTSD has been through a dangerous event. Some people get PTSD after a friend or family member experiences danger or is harmed. The sudden, unexpected death of a loved one can also cause PTSD.

Why do some people get PTSD and other people do not?
It is important to remember that not everyone who lives through a dangerous event gets PTSD. In fact, most will not get the disorder.

Many factors play a part in whether a person will get PTSD. Some of these are risk factors that make a person more likely to get PTSD. Other factors, called resilience factors, can help reduce the risk of the disorder. Some of these risk and resilience factors are present before the trauma and others become important during and after a traumatic event.

Risk factors for PTSD include:

• Living through dangerous events and traumas
• Having a history of mental illness
• Getting hurt
• Seeing people hurt or killed
• Feeling horror, helplessness, or extreme fear
• Having little or no social support after the event
• Dealing with extra stress after the event, such as loss of a loved one, pain and injury, or loss of a job or home.

Resilience factors that may reduce the risk of PTSD include:

• Seeking out support from other people, such as friends and family
• Finding a support group after a traumatic event
• Feeling good about one’s own actions in the face of danger
• Having a coping strategy, or a way of getting through the bad event and learning from it
• Being able to act and respond effectively despite feeling fear.

Researchers are studying the importance of various risk and resilience factors. With more study, it may be possible someday to predict who is likely to get PTSD and prevent it.

Diagnosis
Not every traumatized person develops full-blown or even minor PTSD. Symptoms usually begin within 3 months of the incident but occasionally emerge years afterward. They must last more than a month to be considered PTSD. The course of the illness varies. Some people recover within 6 months, while others have symptoms that last much longer. In some people, the condition becomes chronic.

A doctor who has experience helping people with mental illnesses, such as a psychiatrist or psychologist, can diagnose PTSD. The diagnosis is made after the doctor talks with the person who has symptoms of PTSD.

To be diagnosed with PTSD, a person must have all of the following for at least 1 month:

• At least one re-experiencing symptom
• At least three avoidance symptoms
• At least two hyperarousal symptoms

Symptoms that make it hard to go about daily life, go to school or work, be with friends, and take care of important tasks.

PTSD is often accompanied by depression, substance abuse, or one or more of the other anxiety disorders.

Treatments
The main treatments for people with PTSD are psychotherapy (“talk” therapy), medications, or both. Everyone is different, so a treatment that works for one person may not work for another. It is important for anyone with PTSD to be treated by a mental health care provider who is experienced with PTSD. Some people with PTSD need to try different treatments to find what works for their symptoms.

If someone with PTSD is going through an ongoing trauma, such as being in an abusive relationship, both of the problems need to be treated. Other ongoing problems can include panic disorder, depression, substance abuse, and feeling suicidal.

Psychotherapy
Psychotherapy is “talk” therapy. It involves talking with a mental health professional to treat a mental illness. Psychotherapy can occur one-on-one or in a group. Talk therapy treatment for PTSD usually lasts 6 to 12 weeks, but can take more time. Research shows that support from family and friends can be an important part of therapy.

Many types of psychotherapy can help people with PTSD. Some types target the symptoms of PTSD directly. Other therapies focus on social, family, or job-related problems. The doctor or therapist may combine different therapies depending on each person’s needs.

One helpful therapy is called cognitive behavioral therapy, or CBT. There are several parts to CBT, including:

• Exposure therapy. This therapy helps people face and control their fear. It exposes them to the trauma they experienced in a safe way. It uses mental imagery, writing, or visits to the place where the event happened. The therapist uses these tools to help people with PTSD cope with their feelings.
• Cognitive restructuring. This therapy helps people make sense of the bad memories. Sometimes people remember the event differently than how it happened. They may feel guilt or shame about what is not their fault. The therapist helps people with PTSD look at what happened in a realistic way.
• Stress inoculation training. This therapy tries to reduce PTSD symptoms by teaching a person how to reduce anxiety. Like cognitive restructuring, this treatment helps people look at their memories in a healthy way.

Other types of treatment can also help people with PTSD. People with PTSD should talk about all treatment options with their therapist.

How Talk Therapies Help People Overcome PTSD
Talk therapies teach people helpful ways to react to frightening events that trigger their PTSD symptoms. Based on this general goal, different types of therapy may:

• Teach about trauma and its effects.
• Use relaxation and anger control skills.
• Provide tips for better sleep, diet, and exercise habits.
• Help people identify and deal with guilt, shame, and other feelings about the event.
• Focus on changing how people react to their PTSD symptoms. For example, therapy helps people visit places and people that are reminders of the trauma.

Medications
The U.S. Food and Drug Administration (FDA) has approved two medications for treating adults with PTSD:

• sertraline (Zoloft)
• paroxetine (Paxil)

Both of these medications are antidepressants, which are also used to treat depression. They may help control PTSD symptoms such as sadness, worry, anger, and feeling numb inside. Taking these medications may make it easier to go through psychotherapy.

Sometimes people taking these medications have side effects. The effects can be annoying, but they usually go away. However, medications affect everyone differently. Any side effects or unusual reactions should be reported to a doctor immediately.

The most common side effects of antidepressants like sertraline and paroxetine are:

• Headache, which usually goes away within a few days.
• Nausea (feeling sick to your stomach), which usually goes away within a few days.
• Sleeplessness or drowsiness, which may occur during the first few weeks but then goes away.
• Agitation (feeling jittery).
• Sexual problems, which can affect both men and women, including reduced sex drive, and problems having and enjoying sex.

Sometimes the medication dose needs to be reduced or the time of day it is taken needs to be adjusted to help lessen these side effects.
