Kinds of Anger after Brain Injury

Anger is a very common problem after brain injuries.  When someone with a brain injury has a problem with anger, there are usually several causes acting in combination.  Some people are angry about the injury or problems that may have come with it, such as disabilities and loss of job, friends, money and control over one’s life.  Some people were angry people before their injuries and still have that problem.  People who have always been angry may need psychotherapy to help them learn to cope, and in some cases medication is required.  (In our experience, people unfamiliar with the person or with brain injury are often too quick to assume that personality alone is to blame.)   But many people also develop impulsive anger as a direct effect of the damage to the brain.  In other words, the parts of the brain that normally inhibit angry feelings and behavior have been damaged and do not do their jobs as well.  This means that the person’s anger threshold is lowered so that he or she becomes angry more easily and more intensely.  We can tell that this impulsive anger is directly due to the brain injury when:

  • The anger begins with the brain injury or is made much worse by it
  • Angry feelings come and go relatively suddenly
  • Anger episodes may be in response to minor events
  • The person having the angry episodes is surprised and embarrassed or distressed by them
  • The anger is made worse by physiological stress such as fatigue, pain or low blood sugar

This was the problem Joe had.  Joe was a quiet man, an accountant; active in his church and an assistant little league coach.  He never drank or used street drugs; he was healthy; and he had never been in a fight or in trouble with the law.  He was well liked in the community.  His wife said that he rarely got angry, and when he did he usually sulked.  When his car was hit by a drunk driver and Joe hit his head on the window, all that changed.  He had been knocked out for five minutes but after he was checked out at the Emergency Room they sent him home.  He went back to work a week later but had trouble concentrating and remembering.  Worse, he started yelling at his wife and children, often for little things like laughing loudly at the TV.  One day at work, he broke a computer keyboard by hitting it with a stapler; and he sometimes tore up papers he was working on.  After each of these episodes, he would be very embarrassed and apologetic.  He came for help after loudly cursing at his daughter because she was playing with her program at a Wednesday evening church service.

With Joe, it was clear that he was having impulsive anger resulting from his head injury.  When other more familiar causes of anger are also present, such as difficult personality, alcohol abuse, or anger at the injury itself, the impulsive anger resulting directly from the brain injury can get overlooked.  It is important to try to identify and treat that part of the anger too.

Dealing with Impulsive Anger Resulting from Brain Injury

When brain injured people first wake up from a coma, they are usually disoriented and confused and often they are agitated.  They do not understand what is going on around them, and they are not truly responsible for their own actions.  It is up to the people taking care of then to keep them safe, even if this means restraining them or using medications when absolutely necessary.  As they recover, they gradually come to be able to control their actions.  Their staff and families can then gradually teach them about the best ways to manage their angry feelings.  Because brain injured people’s “anger thresholds” or “flashpoints” have been lowered, they need to relearn how to manage the changed reactions.  They need emotional rehabilitation in addition to physical and cognitive rehabilitation.

Understanding the Anger

The brain injured person is, in some ways, a different person.  What makes him or her angry may be different.  We need to learn what those things are.  Here are some common factors that contribute to anger after brain injury.

Anger Factors

Stimulation factors:

  • High noise or activity level
  • Unexpected events
  • Lack of structure

Personal factors:

  • Frustration
  • Fear or anxiety
  • Embarrassment, shame or guilt
  • Discovery or confrontation of problems
  • Cognitive impairments – especially memory deficits and confabulation (remembering things that did not happen)
  • Communication impairments
  • Rigid thinking

Medical factors:

  • Pain
  • Fatigue
  • Hypoglycemia (low blood sugar)
  • Medications (levels low or high?)
  • Alcohol or drugs

Anger Warning Signs

Speech signs:

  • Loud high voice
  • Cursing
  • Name calling
  • Threats

Behavioral signs:

  • Making fists
  • Increased movement and fidgeting
  • Angry face
  • Moving towards the object of anger
  • Breaking things
  • Throwing things
  • Threatening people
  • Searching for or picking up weapons
  • Hitting, kicking and other forms of violence

Physiological signs:

  • Fast breathing
  • Fast heart
  • Sweating
  • Over-aroused
  • Tense muscles
  • Flushed face
  • Bulging eyes

Mental signs:

  • Fantasies of doing any of the speech or behavioral signs
  • Negative thoughts about others
  • Confusion
  • Feelings of frustration
  • Feelings of fear or anxiety
  • Feelings of embarrassment, shame or guilt
  • Feelings of hurt

Early Strategies

These strategies are for staff and families to use when the brain injured person is too confused to be responsible for his or her actions.  It is important for staff and families to remember during this time that the anger is due to the injury, and they should not take it personally.


  • Make the environment safe
    • Remove potential weapons
    • Keep alcohol and drugs inaccessible
    • Keep vehicles and dangerous tools inaccessible
  • Regulate Level of Stimulation
    • Some need to avoid over stimulation
    • Some need to be kept busy and distracted
  • Provide Appropriate Level of Supervision
    • Provide the least restrictive environment possible
  • Provide Reorientation as Needed
    • Much of the anger in an agitated confused and disoriented person can come from misperceiving and misunderstanding the situation
    • Staff and families should frequently remind the person of where they are, what is happening and why


  • Withdraw
    • Leave the person alone for a short period of time if this can be done safely. As you leave, tell them briefly what you are doing and why. “You are beginning to get upset. We are going to leave you alone for a few minutes so you can calm down.”
  • Distract
    • Change the subject, the focus of activity or the location
    • Use a concrete object as a focus when possible
  • Reorient and Reassure
    • Remind the person of where they are, what is going on and why
    • Try to clear up misunderstandings when this can be done without renewing argument
    • Direct the person in activities that may reduce agitation, such as guided relaxation

Self-Control Strategies

These strategies are to be phased in when the brain injured person has recovered enough learning abilities and awareness to begin to cooperate in learning to control anger.

“Back Off, Calm Down, Try Again”: Because the impulsive anger resulting from brain injury often comes and goes suddenly, an effective way to deal with it is for the angry person to back off, calm down and try again.  This strategy can be phrased in the individual’s own words or whatever expression is comfortable such as “retreat, relax, return” or “take a break” or “time out”.

Back Off: When warning signs appear, the person should leave the situation and go to a safe place. Others will have to cue him or her to leave. If the person will not leave, the other people present should leave instead, if possible. Practicing backing off when not angry (like a fire drill) will help this go more smoothly when it is really needed.

Calm Down: When the person has backed off to a safe place, he or she should work on claming down. Many techniques can be used to calm down including:

  • deep breathing
  • soft music
  • meditation
  • prayer
  • closed eyes
  • physical exercise

Preparing to Return: Once calm, the person may need to rethink the situation and prepare to return. 

Reviewing a list of questions is a possible preparation;

  • Do I need to apologize? 
  • Do I need to explain why I left? 
  • Do I need to tell anyone my feelings? 
  • What can I do to avoid this next time?

Here are some statements to encourage rethinking the situation;

  • “I don’t hate my mother; I’m just angry with her”
  • “Maybe she had a point I should listen to”
  • “He’s not wrong, we just disagree”

Try Again: When the person returns from backing off and calming down he or she may need to

  • apologize,
  • talk through the issue,
  • explain the backing off and feelings
  • resume what he or she was doing.

Once a person has learned to back off, calm down and try again successfully, he or she can work on calming down in the situation without leaving.

Anger Cue Cards

Anger cue cards can be used to remind the brain injured person of their warning signs such as Loud Voice, Tense Muscles, Confusion, or Thoughts of Hitting. These cards should be carried by the brain injured person and optional copies can be placed where anger incidents often happen or where backing off takes place.

A Back Off card might say:

  • “I’m feeling angry, I need to back off”
  • Leave the room
  • Breathe deeply
  • Relax muscles.

Angry Reactions to Brain Injury

Anger at the cause of injury:  The victim of an injury may be angry at the cause of the injury such as a drunk driver, an assailant, a corporation or a government.  Such people often need help finding effective and satisfying channels for their anger.  Often, they can talk this out with a trusted friend or family member.

Grief Reaction: It is part of human nature to grieve when we lose something, not just when someone dies, but also when we suffer an injury or illness. We try to find reasons for our losses. One part of a grief reaction is anger at what we think caused it. This anger can also get displaced onto any handy target. People can work through these reactions by talking out their feelings. This is such a human experience that it usually does not require a psychologist, just a trusted and understanding person. However, poor memory or judgment or emotional or personality problems can complicate grief reactions and psychotherapy may be needed.

Frustration: When frustration contributes to angry reactions, the person needs to be trying easier things. Specific preparation can also be given before difficult tasks. For example, “Now it’s time to go shopping. I know this is sometimes frustrating for you. How will you know if you are starting to get frustrated, and what will you do about it?”

Normal, Legitimate Anger: Brain injured people still have legitimate reasons to get angry. If their legitimate anger is discounted, ignored or “treated”, they may get angrier. If they have expressed their anger inappropriately, their angry actions should be dealt with separately from their legitimate complaint. They should not get their way just because they made a fuss, but the complaint should not be ignored.

Brain injured people often have impaired judgment which can contribute to anger problems.  Cognitive rehabilitation for judgment can help.  People with these difficulties need to check their judgments with caregivers or people they trust.  Alcohol and drugs can contribute to anger problems.  The clearest solution is abstinence but abuse programs or counseling may be needed.  Not taking prescribed medications can also contribute to anger problems.  The doctor should be told if the medications have not been taken as directed and if there have been any problems.


Anger is a common problem following brain injury.  It has many causes, and there are many solutions to be tried.  The rehabilitation team, the family and friends and the brain injured person can all work together to understand and manage the problem to help the brain injured person to work towards recovering self control.

Dallas, you take care of yourself. I've had 14 concussions and if I could go back to being 13 when I too had 2, I would have stopped playing hockey. I promise you'll heal and get back to normal from your 2 but don't risk your life to keep playing. Believe me when I say it isn't worth it. The more you get, the less of a person you seem to become and that anger amplifies and depression takes over. Never lie on your concussion protocol. Only ever go back when you're yourself again, that includes the memory and anger problems. Your life will round out to have so many possibilities other than soccer, so just remember that it isn't worth your life. Suicide may never be in your thoughts now but the more you get, the harder it is to hang on to people and enjoy your life and have clear thoughts and then the thoughts creep up on you even though the thoughts don't seem to be your own. Please be careful.

Hi im Dallas Gill, im 13 years old and i have sustained already 2 concussions. Both of which i sustained playing soccer. Soccer is my everything and it caused me more problems in my life than ever. After i suffered from the second one, i have tons of anger built up all the time. Please if you or someone you know has all this anger get help it can result it things that are un able to be taken back. I don't even remember some of the things i have supposedly done.

I suffered a concussion 8 months ago and my life has changed for the worse. Im 34 yrs old..I have angry outbursts all the time now..and my fiance just left me. I had to quit my job. I cry constantly. I try to take it day by day but the grief is SO thick, almost suffocating. I lost me. And so much more. No one understands because i look fine. Tired but fine. There isn't alot of help out there from doctors. . The best treatments I've found are fish oil, exercise, eating a clean diet, tumeric, making sure I get enough sleep (which never happens, I have an 18 month old) acupuncture, a therapist who knows about tbi, and I'm starting neurofeedback soon since I've heard alot of success with brain injuries. Worst thing to ever happen to me. I remember laying in bed next to my fiance just a week after it happened and I said "Im going to lose everything. I can feel it" and 8 months later I'm still watching it all slip away even as I put everything I have into trying to help myself and stop thus and turn it all around. I'm hanging on by my fingertips. I need a miracle

Last year l fell down a steep flight of stairs. My roommate found me semiconscious. I was admitted to the hospital for one week. There they said l had concussion from the fall.since then, I almost have recovered from stuttering , memory is much better, focusing is still a problem but one thing l wasn't expecting to be faced with is anger issues. Before the fall, l was quiet and calm and in control of my emotions. But now l can go from being calm to frighteningly angry in a matter of seconds. It scares me. I often get embarrassed. I don't like not having any control over my emotions. What l fear is that l could really hurt myself or anyone else should a confrontation arise. I'm scheduled to see a neurologist in a few weeks.

Interesting article. Anger like any emotion can be controlled. I have epilepsy as the result of a serious head injury in the Marine Corps. I had real anger issues at first and then I decided to do something about it. I found a job where anger was not only unacceptable but costly. I was a commission salesman for over forty years. I made an above average income especially during the last 26 when I was a stockbroker. And, no, I didn't hold it in. I replaced it.

My experience with anger, volatility and depression are related my brain injuries yes injuries. The guilt the shame at my behavior is absolutely crippling. What it has done to me and my family can never be taken back. If I just would have known but that's not possible since the old me is gone. I have tried to put in measures to gain space at times when I need it. But people who know but just see me standing in front of them and forget what I'm going through. I look normal, no 1/4 of my skull is missing. Some people love to push, and manipulate that is not a wise thing to do with someone who is trying to keep things constantly in balance as a way to survive. I am constantly trying to keep the demons at bay. Coming upon this site today may or may not help in the long term but in the short term it has reminded me of what I'm dealing with I too have forgotten. I often forget myself the path I am on until like today I search for reasons why? The good things that have come out of it, and there is good, I play music now, I take time to gather my thoughts or leave when I feel cornered. I'm thoughtful and considerate of other peoples situations and try to give people a wide berth. I have a better appreciation for my good days thou they maybe few. I wish i could remember what has happened to me sometimes. Haha i forget to remember auuggghhh! I have had to spend thousands of dollars because none of this was covered by car insurance Healthcare not a thing. I was diagnosed. I knew, something was wrong. I was never treated, simply put I was told there is no help. i love i care i live one day i hope to be alive.

I've come accross this website not knowing what I was looking for and just realised this is a condition. My brother had a quad bike accident and I found him by chance semi-conscious, jaw snapped in half, cut down the head a smashed ankle with his leg bone sticking out. I live 70km from nearest major town 0and took about 40mins for an Ambo from which he was eventually airlifted out. Luckily he recovered physically but the hardest part has been his anger, which till now I never understood. I took over a farm by myself at 19 & my brother came and lived with me at 15, we were always best mates and in business together. Now post accident he is very angry and blames me for every or anything that happens. And the rage, he was a very smart calm person. Everything we've worked for is kind of falling apart. I'm a bit overwhelmed to read other peoples stories that it lasts for years or forever. Sad to think that's it. If anyone can comment below on things they've tried or support. I'm very limited being far from a town and running my own business 7 days a week.

My partner has a frontal lobe injury from 20 years ago. He takes away household takes like cooking, cleaning - which he does well - THEN he feels overwhelmed and yells that he does everything. He absolutely refuses to let anyone help because we don't do things as he does. He's broken every door in the house, slammed every doorknob into the walls. He threatens to punch me, he has spit on me for not agreeing with him, he pushed me into the door yesterday because our car got broken into and he was convinced it was some guys from up the street but all that happened was someone threw our glove box contents around and I offhandedly said, "That sounds like kids." And he lost his mind for me not agreeing with him and it culminated with him slinging me by my arm into the back door and shoving me outside. He later will alternately claim he is sorry or I need to agree with him but it's always "an accident." 
I try to leave the room when he starts yelling and getting angry but he only follows me. I need some guidance for what to do here... is it time to cut my losses after almost 20 years. He's just getting worse and worse and completely blame me and our 10-year old son.

I suffered a tbi 8 years ago. Spent some time on life support. Thought I was fine. Found a great woman who has twins and we had another baby. I watch as I have irrational outbursts with actions I cannot control. I scare myself. Want to check myself into the hospital. It keeps getting worse and I'm so confused. I want to bury a hole and hide in it forever. It's so hard. I have so many other traumatic things that have happened to me in my life time. Am I a monster or a survivor? Monster, evil, devil. All are words that describe myself. 3 months I lost my job, my family at home, and most of my support team is gone as well. Help

Jul 19th, 2015 9:50pm

Anger after tbi is a huge problem for my family. My spouse, who was such a calm person before the car accident, has morphed into such an angry person who is so prone to yelling and screaming, often without provocation. I am not a fortune teller and cannot easily predict what will set him off. As much as I can provide a calm and peaceful home environment and as often as I try to be accommodating and cooperative, he still lashes out in anger. It's been almost 16 years since his accident and his anger is destroying our family. I don't think we'll be together for much longer and it breaks my heart. He was such a good person before his tbi and I miss who he used to be. My heart has been heavy ever since his tbi. It destroyed our lives.

My TBI was nearly 42 years ago. In the last ten years I have had increasing issues with anger, especially when I get frustrated after dealing with my children but at times it is with other issues. Six years ago I divorced my first husband. I still have times when he pushes my buttons. I know the intense anger is from the head injury. I just don't know what to do about it, how best to control it without feeling drugged.

Jan 24th, 2015 5:26pm

(Responding to the previous comment "can it go away") My control difficulties are completely irrational. I feel as if the "real" me is an observer unable to stop what is happening. Initially, I dealt with the problem by trying to warn people I had difficulty in this area. That was a bad strategy. It worked part of the time, but was was just as likely to put others into a defensive mode that actually made it more likely I would loose control.

The strategy that worked was recognizing that my "anger" was actually an extension of the confusion I experience due to mental fatigue when I encounter too many things to think about, and I start feeling mentally drained. I can usually feel my thoughts slowing, but sometimes my first warning is noticing my speech is getting "thick." Slurred and slow speech and slow reactions (sometimes only discernable because other start talking over me, and not waiting for me to finish) are danger signals. 

When I recognize I am in that state, it is time to immediately withdraw. Unfortunately, many situations don't allow for sudden withdrawal. My solution was to never go anywhere alone, but to always have a "backup" person with me who understands my situation and can take over for me. For example, I take one of my adult children with me when I go shopping, and I do all of my decision-making before I leave to go shopping, going over my list and comparing it with the store's online specials. Then I shop as long as my thinking is clear, although I have had days in which I considered my thinking clear, but strangers were coming up to me and asking if I was "OK..." Obviously my self-evaluation of clear thinking is not always correct. (My kids took away my car two weeks ago...) 

When I become aware I am slipping into a confused mental state, I turn over control to one of my children, and they take over for me. That is how I avoid irrational outbursts. 

Oct 21st, 2014 5:27pm

can it go away? or is it something permanent we have to learn to control?
