8 Personality Changes After a Traumatic Brain Injury

The human mind is a fascinating thing – it controls your entire personality, the way you behave, and the way you display your moods. Unfortunately, a single injury can change the way you behave. Many people go through accidents every day and most of them can suffer from a major accident. A major car accident can lead to brain injuries and even surgery.

Personality Changes After A TBI

People might suffer from a traumatic brain injury that can also lead to personality changes. Even if it’s just a concussion, people can still go through an emotional change. Obviously, the way our mind processes the emotions and also depicts information changes with the accident, so it’s quite obvious that the emotions can be wrecked in a negative way as well.

Common Symptoms After a Brain Injury

People suffer from different emotions after an injury. This change of emotions can alter their entire personality. The most common mood changes that people can experience after a brain injury are:

  • Irritability
  • Anger
  • Depression
  • Egocentricity
  • Social Anxiety
  • Mood Swings
  • Emotional Breakdown
  • Impulsiveness

Consider your personality as a set of characteristics and your mood as your present situation. In a normal situation, our moods keep on changing during a head injury, such moods can become quite common. Moods, including depression, distress, or frustration following a head injury, can contribute to the mental symptoms of changes in personality being wrong and confusing to patients and their families. Fortunately, most of these changes in personality can easily go away if you take proper peripheral neuropathy treatment following a brain injury.

Why Do People Suffer from Personality Changes After a Brain Injury?

Almost 70% of people who have been in a car accident and are suffering from brain injuries have reported having emotional changes in their personality. Even though serious medical issues like depression and anxiety require psychiatric treatment, most of the other mood swings can actually resolve with time.

Personality changes following a TBI can start from two different sources:

  • Psychological changes in the brain.
  • A natural response to changes in life.

Emotional Symptoms After a Brain Injury

Brain damage is mentally painful. It’s natural to miss the life you once had and continue to figure out how to deal with lingering complications. Brain injury patients may be affected by weakened interactions mentioned above and may have unexplained changes in behavior. Many patients are going through a dysregulated neurovascular coupling, this means that certain brain regions are hypoactive and are not performing their jobs while the other regions are insanely hyperactive and are trying to do too much. In any other case, the brain is known to work overtime just to complete the work.

Let’s explore the different changes this brain injury can cause a patient emotionally:

Anger and Irritation

Irritation and anger are one of the more commonly reported symptoms at the car accident clinic by patients who are recovering from brain injuries post-accident. It is typical to react in a much more dramatic way than you normally would.

If you are still not recovered from the injury, your mind and body are handling a lot more than they are normally used to. This is why small inconveniences start becoming a big deal. These emotional outbursts of irritation, anger, and unwanted mood swings can be controlled if you tried looking for ways to avoid overstimulation of emotions.

Anxiety and Depression

Well, all of us have anxiety in our daily lives one way or the other. Although after an injury, the anxiety may get out of control and get worse. You might experience different emotions like feeling on the edge, failing to sleep properly, negative thinking, and the most common – having flashy feelings in the stomach. Just after brain damage, you may notice yourself concerned in ways you’ve never experienced previously. Or, you might notice that the previous anxiety that you were suffering is getting worse. If you have had depression in the past, it can also be triggered after the injury.

If you are experiencing any suicidal thoughts or the feeling of being extremely negative, it is okay to seek professional help from a psychiatrist. Research showed that people suffering from brain injuries had a double suicide rate than those who didn’t.

Emotional Breakdown

It’s common to cry or tear up from sadness or disappointment after a TBI triggers and it does result in lingering and painful symptoms. Really, it’s safe to sob and express any of the feelings you’re experiencing. Sometimes it is common for patients to get confused over their present situation and cry over their majority problems. Even in car accident clinics, people have reported losing their emotions in front of the doctor. Emotional lability can cause extreme happiness and sadness – even in the most inconvenient moments. This can be your body’s way of handling the overwhelming emotions so don’t control your tears. Instead, share your emotions (even if they are meaningless) with someone you genuinely trust.


People can also become egoistic after suffering from brain injuries. They can behave to be self-centered, and seem to be oblivious of the thoughts or desires of their families and friends. In distress, it is typical for someone to want to concentrate on their own interests, although this can be highly amplified for an individual with brain damage. Such cognitive impairments mean that the patient is oblivious to the intense changes in personality as well as the needs of the others. Since they are your family, you need to consider things that might be hurtful and explain to them what you are feeling nowadays.    


A patient suffering from a brain injury may have a propensity to talk or act without caring about the potential effects of their actions. This can add to humiliation in social settings, such as saying an offensive joke without realizing that it could offend the person they’re talking to. Or, in some cases, it can lead to logistical problems, such as whether they agree to carry out a mission that they are not reasonably able to perform, or if they expend more cash than they can spare.

Tips to Handle Emotions Following a Brain Injury

Although it is mandatory to visit your doctor to get a peripheral neuropathy treatment as well as with your psychiatrist in case you are suffering from any emotional distress. Here are a few things that you must do on your own for a complete recovery:

  • Identify the points and situations that trigger you.
  • Talk to family members and friends who have been with you for a long time and want to see you get better.
  • Have a plan to handle your emotions whenever you are feeling emotionally distressed.
  • Exercise to release your stress (physical and mental). But make sure that you have the doctors’ approval.
  • Keep a record of how your day went and try to remember different setbacks and emotional distress you went through.
  • Get the right treatment and go to your doctor until he clears you as completely healthy.


Brain injuries can have a bad impact on one’s personality. It’s normal to go through emotional changes like mood swings, irritability, and anger. It is important to get the right treatment and make sure that you are following your doctor.
