A brain injury can change your personality

On Behalf of | Apr 23, 2025 | Brain Injuries

A serious brain injury can cause more than physical pain. It can also change how someone thinks, feels and acts. 

These changes may affect relationships, work and everyday life. Understanding the impact and your legal rights is important if you or someone you love has been hurt.

Types of brain injuries linked to car accidents

Car accidents may cause traumatic brain injuries (TBIs). Some common types include:

  • Concussions, caused by the brain shaking inside the skull

  • Contusions, which are bruises on the brain and may need surgery

  • Diffuse axonal injuries, which involve tearing of brain fibers

  • Penetrating injuries, where an object enters the skull

Even mild TBIs can lead to serious long-term effects if not properly treated.

Altered personality after a brain injury

The brain controls behavior, emotions and judgment. When certain areas are damaged, personality changes can happen. These may include mood swings, lack of impulse control, anxiety, depression or even aggressive behavior. Some people become quiet or withdrawn, while others may act in ways that are out of character.

In New Jersey, the person who suffered the brain injury can file a personal injury claim. If the injury has harmed the marriage, the spouse may also file a loss of consortium claim. This is meant to compensate for the loss of companionship and support. 

If a brain injury has changed your life or affected your loved ones, seeking legal guidance will help you explore your options.
