How Brain Injury Leads to Personality Changes

Home > Ernst Law Group Blog > How Brain Injury Leads to Personality Changes

One of the most dramatic impacts of a brain injury, especially for the loved ones of the victim, is the changes in behavior that can occur as a result. A traumatic brain injury causes different symptoms depending on the area of the brain that is affected, and two patients rarely, if ever, experience the same exact symptoms.

Behavioral and emotional changes typically occur when a person’s frontal lobe is damaged. This is the area of the brain that helps to dictate our personalities and allows us to control impulsivity. When the frontal lobe sustains damage, it can be difficult for people to practice self-control.  A person with frontal lobe damage may not be able to control their anger. They may become aggressive, and they make inappropriate comments.

In other cases, a person will “lose their effect.” In other words, their personality becomes flat and they seem to lack any emotion at all. The person may seem like a shadow of themselves after the brain injury. Some of the most common behavioral and emotional issues that occur after a traumatic brain injury are:

  • Physical or verbal outbursts
  • Impulsive behavior
  • Negativity
  • Apathy
  • Intolerance
  • Inflexibility
  • Risky behaviors or lack of impulse control
  • Depression or anxiety

It is also not unheard of for people with damage to the brain to exhibit mood swings. Victims often lose their ability to regulate their emotions, feeling giddily happy one moment and crushingly sad the next. Another victim may laugh or cry suddenly with no reason to do either. At times, a victim is aware of these changes, but not all are. Some people experience these mood and behavioral changes without realizing that anything is different.

Anyone who has experience a brain injury or suspects that they may have should seek medical attention as soon as possible. While recovery varies from patient to patient, beginning treatment as soon as possible has been shown to have a positive effect.
