How a brain injury can change personality in your family member


A brain injury is a traumatic event for the victim of the damage. But the impact of a traumatic brain injury goes beyond the victim. A brain injury can change personality. Specifically, damage to the frontal lobe can be the most devastating for family members because it can change the personality of the injured victim so profoundly.

The Frontal Lobe Is in the Cerebrum

The brain can be divided into three main structures:

  • Cerebrum
  • Brainstem
  • Cerebellum (which sits on top of the brain stem)

The last two — the brainstem and cerebellum [the two structures in brown in the picture below] — are older parts of the brain because they evolved longer ago. These areas mostly are responsible for automatic physical behaviors such as breathing, swallowing, and heart rate that are necessary for life.

The cerebrum is the most recently evolved most elaborate and largest brain structure. (The words cerebrum – the newer part – and cerebellum – the older part – look and sound very similar.  Think cerebrum = drum because it is larger, and cerebellum = bell because it is smaller.)

The cerebrum [the blue, green, red, and yellow structures in the picture to the right]
is divided into 5 lobes that are responsible for different functions. The five lobes are the

  • frontal lobe [blue structure to the right}
  • occipital lobe [yellow structure]
  • temporal lobe [red structure]
  • parietal lobe [green structure]
  • limbic lobe [not pictured]

Frontal Lobe Brain Injury Can Change Personality

The frontal lobe controls many of the personality and behavior functions that differentiate
human beings from one another. The frontal lobe is responsible for:

  • problem solving
  • spontaneity
  • memory
  • language
  • motivation
  • judgment
  • impulse control
  • social and sexual behavior

A frontal lobe brain injury change change personality, sometimes resulting in permanent mental and personality changes.
